Maloklusi kelas III dapat didefinisikan sebagai kelainan wajah skeletal dengan karakteristik posisi mandibula lebih maju terhadap dasar cranium dan atau terhadap maksila. Ada tiga pilihan perawatan untuk maloklusi kelas III dentoskeletal yaitu; modifikasi pertumbuhan, kamuflase dan bedah orthognatik. Artikel ini mempresentasikan kasus seorang pasien dewasa dengan maloklusi kelas III dentoskeletal yang dirawat dengan ortodontik kamuflase menggunakan teknik Begg. Seorang pasien laki-laki, berusia 16 tahun, didiagnosa maloklusi kelas III Angle dengan hubungan skeletal kelas III dan gigi depan maksila dan mandibula berjejal. Perawatan menggunakan alat cekat teknik Begg dengan pencabutan premolar kedua maksila dan premolar pertama mandibula serta elastis intermaxillar kelas III. Kesimpulan hasil perawatan selama 10 bulan menunjukkan bahwa kamuflase ortodontik dapat dianggap sebagai terapi yang efektif untuk koreksi maloklusi kelas III dentoskeletal. ABSTRACT: A Camouflage Treatment Of Dentoskeletal Class III Malocclusion In Adult Using Begg Technique B. Class III malocclusion can be defined as a skeletal facial deformity characterized by a forward mandibular position with respect to the cranial base and or the maxilla. There are three main treatment options for dentoskeletal class III malocclusion: growth modification, orthodontic camouflage and orthognatic surgery. The article presented a case of an adult patient with dentoskeletal class III malocclusion treated with orthodontic camouflage treatment with Begg technique. A male patient, 16 years old, diagnosis malocclusion Angle class III, skeletal class III with crowding anterior teeth maxilla and mandibular. Using the fixed appliance, Begg technique, with the extraction of second premolars maxilla and first premolars mandibular. The appliance is completed with intermaxillary class III elastics. The results for 10 months of this treatment indicated that orthodontic camouflage can be considered an effective therapy for corection of dentoskeletal class III malocclusion.

This cephalometric study investigates the changes in the facial skeleton and dento-alveolar structures which occur during orthodontic treatment of the Class II Division 1 malocclusion by extraction of four first premolars followed by fixed appliances. The Begg and edgewise appliances are compared, and both are contrasted with a group of untreated Class II Division 1 subjects. The main effects of treatment were in the dento-alveolar structures, the changes in the overall facial pattern being small and largely due to extrusion of the molars during overbite reduction. Molar extrusion tended to interrupt forward growth rotation of the mandible, temporarily making it more backwards in direction, and increasing the lower anterior face height. An increase in the posterior lower face height was also noted in the edgewise group. Whilst SNA, and therefore ANB, reduced significantly during treatment, this was probably the result of palatal root torque to the upper incisors. The Begg appliance was more successful than edgewise in this respect.

Latar Belakang: Maloklusi Pseudo kelas III ditandai dengan hubungan yang tidak harmonis antara relasi anteroposterior rahang dan posisi mandibula terhadap maksila. Ketidakharmonisan tersebut dapat disebabkan karena mandibula yang normal dengan maksila retrusif. Maloklusi pseudo kelas III mempunyai perhitungan yang menunjukkan bentuk antara klas I dan skeletal klas III. Perbedaanya hanya pada sudut gonial dimana pada skeletal klas III sudutnya lebih tumpul, sedangkan pada sampel pseudo klas III, sudut gonial lebih mirip dengan klas I. Perawatan ortodontik dengan alat cekat teknik Begg dapat juga untuk merawat maloklusi Angle kelas III, termasuk maloklusi skeletal yang menyertainya. Tujuan: memaparkan perubahan dental dan skeletal setelah perawatan dengan alat cekat teknik Begg. Kasus: perempuan 20 tahun mengeluhkan gigi-gigi rahang atas ada yang tumbuh di belakang dan rahang bawah nyakil sehingga menganggu penampilan dan mengurangi rasa percaya diri. Diagnosis: Maloklusi Angle Klas III subdivisi serta hubungan skeletal klas III dengan maksila retrusif dan mandibula protusif disertai Crossbite: 12, 11, 21, 22 terhadap 34, 32,31, 41, 42, 43. Perawatan: menggunakan alat cekat teknik Begg tanpa pencabutan. Kesimpulan: Hasil menunjukkan crowded terkoreksi, overjet dan overbite terkoreksi, relasi molar menjadi klas I. Background: Pseudo class III malocclusion characterized by disharmony between anteroposterior relationship of jaw and mandibulae position toward maxilla. This disharmony cause by normally shaped mandibles and underveloped maxillae. Pseudo clas III malocclusion is an intermediate form between class I and skeletal clas III malocclusion. The only exception was the gonial angle, which was generally more obtuse in the skeletal class III sample. Measurement of gonial angle in the pseudo class III sample was found to be rather similar to class I sample. Fixed Begg orthodontic appliance can be used to treat Angle’s class III malocclusion accompany with skeletal problem. Purpose: to describe dental and skeletal changes after begg fixed orthodontic. Case: 20 year old woman complained of crowded maxilla front teeth and mandible protrusion. Diagnosis: malocclusion Angle class III subdivision, skeletal class III with maxilla retruded and mandibular pronation along with anterior crossbite: 12, 11, 21, 22, to 34, 32, 31, 41, 42, 43. Treatment: using the Begg fixed appliance techniques without extraction. Conclusion: The result showed that crowded, overjet and overbite corrected, and molar relation become class I.

Gigi kaninus sangat penting untuk estetika dan fungsi mastikasi seseorang. Impaksi gigi adalah gagalnya gigi untuk muncul ke dalam lengkung gigi yang dapat disebabkan karena kekurangan ruang, adanya sesuatu yang menghalangi jalur erupsi gigi atau karena faktor keturunan. Prevalensi impaks gigi kaninus maksila adalah 0,9-2,2%, sedangkan impaksi gigi kaninus mandibula lebih jarang terjadi. Alternatif perawatan gigi impaksi kaninus maksila adalah operasi exposure dan diikuti dengan kekuatan ortodontik untuk membantu erupsi dengan alat cekat ortodontik. Tujuan dari perawatan adalah untuk koreksi malrelasi dan malposisi gigi geligi, khususnya koreksi gigi kaninus impaksi menggunakan teknik Begg. Pasien laki-laki, 19 tahun, gigi sangat berjejal, gigi kaninus kanan kiri rahang atas dan gigi kaninus kanan rahang bawah impaksi, kelas I, deep overbite, overjet 3 mm dan overbite 8,8 mm. Perawatan dilakukan dengan menggunakan alat cekat Begg dengan tanpa pencabutan. Operasi exposure dilakukan untuk membuka gigi kaninus kanan kiri atas yang impaksi yang diikuti perekatan braket ortodontik. Kawat busur multiloop, anchorage bend dan elastik intermaksiler klas II digunakan pada tahap leveling dan unraveling. Dalam waktu 14 bulan,overbite terkoreksi, gigi kaninus kanan kiri atas sudah erupsi, overjet 3,00 mm, overbite 3,00 mm. Saat ini perawatan masih berlangsung pada tahap leveling dan unraveling untuk koreksi kaninus yang impaksi. Perawatan maloklusi angle klas I dengan berjejal dan impaksi kaninus maksila dapat dilakukan dengan operasi exposure gigi kaninus impaksi diikuti alat cekat Begg. Orthodontic Treatment of Class I Malocclussion with Canine Impaction Using Begg Fixed Appliance. Canine is very important for aesthetic and masticatory function. Impaction refers to a failure of tooth to presence into the dental arch, usually due to either space deficiencies, the presence of an entity blocking the path of tooth eruption or due to hereditary factors. Prevalence of maxillary canines impaction is 0.9 to 2.2%, while the mandibular canine impaction is less common. Alternative dental care is impacted maxillary canine exposure surgery and followed by orthodontic force for help the eruption with fixed orthodontic appliance. The goal of treatment is to correct malrelation and malposition of teeth. Patient man, 19 years old, very crowded teeth, maxillary right and left canine and mandibular right canine impaction, Angle Class I, deep overbite, 3 mm overjet and overbite 8,8 mm. Treatments performed using Begg fixed appliances without extraction. Exposure surgery is done under the right and left maxillary canine impaction followed orthodontic bracket bonding. Multiloop arch wire, bend and elastic anchorage intermaksiler class II used at the stage of leveling and unraveling. Within 14 months, overbite was corrected, maxillaryr right and left canine eruption, Angle Class I canine relationship, 3.00 mm overjet, 3,00 mm overbite. Current treatment is still ongoing at leveling and unraveling stage.

ABSTRACT: Repositioning of Palatally Impacted Canine in Orthodontic Treatment Using Begg Fixed Appliance. Palatally impacted canine often leads to esthetic complaints. Genetic factor is dominant followed by such other factors as dental arch discrepancy, tooth size, retention of deciduous teeth, early decay, premature extraction, abnormal position of tooth germ, lateral incisor agenesis, and cysts. This article provides information about the treatment of palatally impacted maxillary canine case in a skeletal class I malocclusion using Begg fixed appliance technique. A 15-year-old female patient came to the orthodontia clinic of RSGM Prof. Soedomo FKG UGM. The subjective examination found that the patient was disturbed by her protrusive, gapped front teeth. Then, the objective examination indicated the presence of rudimentary, lateral incisor agenesis of right and left upper jaw, and upper left palatally impacted canine. In addition, there was a transposition of upper right canine to lateral incisor area as well as a midline shift. Angle class I malocclusion with class I skeletal relationship and bimaxillary retrusion along with maxillary incisor protrusion and mandibular incisor retrusion also occurred. The treatment began with rudimentary tooth extractions. The first stage used a multiloop archwire for leveling and unraveling of anterior teeth as well as correction of midline shift. The button attached to the impacted canine could tie the ligature wire to the archwire that served to attract the palatally impacted canine in the dental arch. The orthodontic treatment in cases of palatally impacted maxillary canine with skeletal class I malocclusion using Begg fixed appliance technique can be applied with a good treatment result.

Perawatan gigi berjejal biasanya membutuhkan pencabutan gigi untuk mendapatkan ruang yang akan digunakan untuk pengaturan gigi. Pencabutan gigi premolar kedua membutuhkan penguatan penjangkaran (anchorage reinforcement) pada segmen posterior. Evaluasi perawatan gigi berjejal dengan pencabutan gigi premolar kedua menggunakan alat cekat Begg. Pasien perempuan usia 18 tahun mengeluhkan gigi depan atas dan bawah berjejal. Karies besar terdapat pada tonjol palatinal gigi premolar kedua kiri atas. Diagnosis pasien adalah maloklusi Angle kelas I, hubungan skeletal kelas I, jarak gigit 2,8 mm, tumpang gigit 3 mm, crowding anterior dan posterior, serta pergeseran garis inter insisivus rahang bawah ke kiri sebesar 2 mm. Pengukuran indeks iregularitas Little menunjukkan nilai 12,6 (berjejal berat). Perhitungan determinasi lengkung dan metode Kesling menunjukkan toleransi pergerakan molar rahang atas ke mesial sebesar 1,2 mm pada sisi kanan dan kiri (penjangkaran maksimum). Pasien dirawat menggunakan alat cekat Begg dengan pencabutan keempat gigi premolar kedua. Empat gigi molar kedua disertakan sebagai gigi penjangkar untuk memperkuat keempat gigi molar pertama. Hasil pengukuran pergerakan gigi molar pertama ke mesial setelah perawatan selama 29 bulan menggunakan metode dari Ziegler dan Ingervall menunjukkan terjadi pergerakan gigi molar ke mesial sebesar 1,2 mm pada sisi kanan dan 0,7 mm pada sisi kiri. Nilai indeks iregularitas Little adalah 1,9. Gigi molar kedua sebagai komponen penguat penjangkar efektif untuk meminimalkan anchorage loss pada perawatan gigi berjejal dengan pencabutan gigi premolar kedua menggunakan alat cekat Begg. ABSTRACT: Anchorage Reinforcement in Orthodontic Treatment of Crowded Second Premolar Extraction Case Using Begg Appliance. Orthodontic treatment for crowded teeth may need a tooth extraction. The extraction of second premolars may need anchorage reinforcement in posterior segment. To evaluate the treatment progress of crowded teeth with second premolars extraction uses Begg appliance. An 18 year old female patient complained of her crowded teeth in upper and lower arch. The case was Angle class I malocclusion with class I skeletal pattern, with over jet 2.8 mm and over bite 3 mm. The crowded teeth were present in anterior and posterior segments. There was dental midline discrepancy, with the lower arch midline shifted 2 mm to the left. Little Irregularity Index scored 12.6 (severely crowded). Arch length determination and Kesling’s set up model assesment show that a maximum anchorage was necessary. The patient was treated using Begg appliance and four second premolars were extracted. The four second molars were included as anchor teeth. After 29 months of treatment, the movement of maxillary first molars was measured using the method from Ziegler and Ingervall. The mesial movement of right maxillary first molar was 1.2 mm and 0.7 mm for maxillary first molar. Little Irregularity Index scored 1.9. Adding second molars as ancor teeth was effective to minimize anchor loss in orthodontic treatment using Begg appliance with second premolars extraction.

Maloklusi kelas III skeletal pada umumnya memiliki hubungan rahang yang prognatik, yaitu mandibula terletak lebih maju dari maksila. Perawatan kamuflase non pembedahan pada pasien dewasa dengan maloklusi kelas III memerlukan pencabutan dua gigi premolar mandibula atau empat gigi premolar untuk memberikan ruang retraksi gigi incisivus mandibula. Prinsip perawatan teknik Begg adalah mekanisme gaya differensial dengan menggunakan gaya yang ringan dan kontinyu. Penggunaan elastik intermaksiler kelas III menyebabkan ekstrusi gigi molar atas, retrusi gigi insisivus bawah, rotasi mandibula searah jarum jam dan perubahan posisi kondilus. Penelitian ini bertujuan untuk mengetahui perubahan linier dan anguler posisi mandibula pada perawatan kamuflase maloklusi kelas III skeletal setelah dilakukan perawatan ortodontik dengan teknik Begg. Penelitian dilakukan pada 20 pasang sefalogram lateral dari subjek laki-laki dan perempuan usia 18-25 tahun yang memenuhi kriteria penelitian. Seluruh subjek yang dirawat dengan teknik Begg disertai pencabutan dua gigi premolar pertama bawah. Perubahan posisi mandibula ditentukan dengan perubahan titik Pg dan Pg. terhadap sumbu X dan sumbu Y sedangkan perubahan anguler dengan melihat perubahan sudut Y-axis. Data yang diperoleh dianalisisi dengan paired t test. Hasil penelitian perubahan posisi mandibula setelah perawatan ortodontik kamuflase dengan alat cekat teknik Begg menunjukkan perubahan yang bermakna (p<0,05). Titik Pg mengalami pergeseran ke arah posterior dan inferior dan sudut Y-axis mengalami peningkatan berarti terjadi rotasi searah jarum jam.Skeletal Class III malocclusion generally has prognatic jaw relationship. The mandibular is more forward than the maxilla. Camouflage non-surgical treatment in adult patients with Class III malocclusion required extraction of two mandibular premolars or four premolar teeth to give a space of mandibular incisors teeth retraction. The Begg technique treatment principle is the mechanism of differential force using light and continuous force. The use of inter-maxillary elastic Class III causes the extrusion of upper molars, retrusion of lower incisors, clockwise rotation of the mandible and changing of condyle position. This research aims to determine the linear changing and angular position of the mandible on the camouflage treatment of skeletal Class III malocclusion after orthodontic treatment with Begg technique. The research was conducted on 20 pairs of lateral cephalogram of men and women aged 18-25 years who met the research criteria. All subjects were treated with Begg technique with extraction of two lower first premolars. The changing of mandibular position is determined by changing the point Pg and Pg. to X axis and Y axis, while the angular changing is determined by looking at the changing of Y-axis. The obtained data were analysed with paired t test analysis. The results show that there are significant changes in mandibular position after camouflage orthodontic treatment with fixed appliance of Begg technique (p<0,05). Pg point is shifted towards the posterior and inferior, and Y-axis angle increases. It means that the clockwise rotation has happened.

ABSTRACT Objective: To assess the maxillary second molar (M2) and third molar (M3) inclination following orthodontic treatment of Class II subdivision malocclusion with unilateral maxillary first molar (M1) extraction. Materials and Methods: Panoramic radiographs of 21 Class II subdivision adolescents (eight boys, 13 girls; mean age, 12.8 years; standard deviation, 1.7 years) before treatment, after treatment with extraction of one maxillary first molar and Begg appliances and after at least 1.8 years in retention were retrospectively collected from a private practice. M2 and M3 inclination angles (M2/ITP, M2/IOP, M3/ITP, M3/IOP), constructed by intertuberosity (ITP) and interorbital planes (IOP), were calculated for the extracted and nonextracted segments. Random effects regression analysis was performed to evaluate the effect on the molar angulation of extraction, time, and gender after adjusting for baseline measurements. Results: Time and extraction status were significant predictors for M2 angulation. M2/ITP and M2/IOP decreased by 4.04 (95% confidence interval [CI]: −6.93, 1.16; P = .001) and 3.67 (95% CI: −6.76, −0.58; P = .020) in the extraction group compared to the nonextraction group after adjusting for time and gender. The adjusted analysis showed that extraction was the only predictor for M3 angulation that reached statistical significance. M3 mesial inclination increased by 7.38° (95% CI: −11.2, −3.54; P < .001) and 7.33° (95% CI: −11.48, −3.19; P = .001). Conclusions: M2 and M3 uprighting significantly improved in the extraction side after orthodontic treatment with unilateral maxillary M1 extraction. There was a significant increase in mesial tipping of maxillary second molar crowns over time.

Cross bite merupakan kondisi dimana satu gigi atau lebih mengalami malposisi ke arah bukal atau lingual atau labial terhadap gigi antagonisnya. Cross bite dapat terjadi pada gigi anterior maupun posterior. Cross bite posterior dapat terjadi sebagai akibat kurangnya koordinasi dimensi lateral antara lengkung gigi rahang atas dan rahang bawah. Cross bite posterior dapat terjadi secara bilateral atau 2 sisi maupun unilateral atau 1 sisi. Berbagai penyebab cross bite posterior unilateral diantaranya adanya malposisi gigi ke lingual pada gigi rahang atas, adanya kebiasaan buruk seperti bertopang dagu satu sisi dan adanya pengaruh deviasi mandibula ketika menutup mulut. Tujuan artikel ini adalah menyajikan perawatan ortodontik cross bite posterior unilateral dengan teknik Begg. Pasien perempuan umur 19 tahun mengeluhkan gigi-gigi depan serta belakang atas dan bawah berjejal dan tidak nyaman untuk mengunyah. Diagnosis kasus adalah maloklusi Angle klas I, hubungan skeletal klas I dengan protrusif bimaksilar, protrusif bidental, crowding gigi anterior atas dan bawah, crowding gigi posterior atas kiri, edge to edge bite pada beberapa gigi anterior, cross bite antara gigi 22 dan 32, cross bite posterior unilateral pada sisi kanan, pergeseran rahang bawah kearah kiri, serta pergeseran midline gigi rahang bawah dan rahang atas kearah kiri. Pasien dirawat menggunakan alat cekat teknik Begg. Koreksi cross bite dilakukan dengan ekspansi 1 sisi pada rahang atas kanan serta dengan pemasangan cross elastic untuk menarik gigi posterior bawah yang berada di luar lengkung. Setelah perawatan selama 11 bulan, cross bite posterior pada sisi kanan terkoreksi. ABSTRACT: Unilateral posterior cross bite treatment using fixed orthodontic Begg appliance technique. Cross bite is a condition where one or more teeth may be abnormally malposed buccally or lingually or labially with reference to the opposing tooth or teeth. Cross bite can be classified based on location as anterior and posterior cross bite. Posterior cross bite occurs as result of lack of coordination in the lateral dimension between the upper and the lower arches. Posterior Cross bite can be unilateral involving one side of arch or bilateral which involves both sides. Posterior cross bite can be occur as result of a number of causes such us lingual positioning of upper tooth, presence of one side chin propped habit and presence of occlusal interferences can result in deviation of the mandible during jaw closure. The purpose of this articles to present unilateral posterior cross bite correction using Begg technique A 19 years old female patient complained of upper, lower front and back teeth crowded and uncomfortable for mastication. Diagnosis are malocclusion Angle Class I, Class I skeletal relationship with bimaksilar protrusive, upper and lower incisor retrusive, upper and lower anterior teeth crowding, upper left posterior teeth crowding, anterior edge to edge bite on several anterior tooth, anterior cross bite on 22 and 32, unilateral posterior cross bite on right side, shift to the left of mandible, shift to the left of the median line maxilla and mandible, The patien treated with fixed appliance Begg technique. One side expansion of maxilla on right side and posterior cross elastic are used to correct posterior cross bite. After 11 months of treatment, unilateral posterior cross bite on right side corrected.

Background: Bimaxillary and bidental protrusion Class I Angle malocclusions have a characteristic convex facial profile and protrusion lips due to the labial inclination of the anterior teeth. Extraction of the first four premolars is the most common choice for orthodontic treatment of these cases when all the permanent teeth are complete and in good condition. Orthodontic treatment can be performed using the Begg or Straightwire techniques. Purpose: This study aims to investigate the difference in the effect of orthodontic treatment with Begg and Straightwire appliances on molar position, occlusal plane, and anterior and posterior facial height. Methods: Sixty pairs of lateral cephalograms before and after the treatment of patients with bimaxillary and bidental protrusive Angle malocclusion Class I, aged 18–35 years old, who underwent orthodontic treatment using the Begg and Straightwire techniques with the extraction of all first premolars that met the inclusion criteria. Data analysis was performed using two-way repeated analysis of variance (p<0.05) and Pearson correlation (p<0.05). Results: Molar position, occlusal plane angle, and anterior and posterior facial heights increased significantly after the Begg technique treatment and decreased significantly after the Straightwire technique treatment (p<0.05), but there were no significant differences between the four variables in the two techniques (p>0.05). Medium correlation was found between variables in both the Begg and Straightwire techniques. Conclusion: Molars were extruded and mesialized and the occlusal plane angle and height of the anterior and posterior faces increased after the Begg appliances treatment. The molars moved mesially and occlusally and there was a decrease in the occlusal plane angle, as well as the height of the anterior and posterior faces, after treatment with the Straightwire appliances. However, there was no difference between the two techniques.

A retrospective assessment of treatment outcome in a group of 82 orthodontic fixed appliance cases was carried out using the Peer Assessment Rating Index (PAR) in order to explore the usefulness of the PAR index as a means of differentiating the change associated with treatment. Two different fixed appliance techniques, the pre-adjusted Edgewise and the Begg appliance had been used to treat these cases, and all had been under the care of one Consultant Orthodontics. The mean percentage reduction in PAR for the group as a whole was 74 per cent. Comparison of the two different appliance types found that the pre-adjusted Edgewise group achieved a significantly greater reduction in PAR score (81 per cent), than the Begg group (65 per cent). Cases with a low PAE score prior to treatment tended to fare more poorly in terms of percentage reduction and this was more marked for those cases treated with the Begg appliance. Although the PAR index has a high degree of reproducibility, it was found that even the small error present can lead to problems of interpretation if the nomogram categories are used as a method of comparison. Some potential problems in undertaking studies such as this using the PAR index to assess treatment outcome are discussed.

ABSTRACT Objective: To evaluate the skeletal, dentoalveolar, and soft tissue effects of the Forsus FRD appliance with miniplate anchorage inserted in the mandibular symphyses and to compare the findings with a well-matched control group treated with a Herbst appliance for the correction of a skeletal Class II malocclusion due to mandibular retrusion. Materials and Methods: The sample consisted of 32 Class II subjects divided into two groups. Group I consisted of 16 patients (10 females and 6 males; mean age, 13.20 ± 1.33 years) treated using the Forsus FRD EZ appliance with miniplate anchorage inserted in the mandibular symphyses. Group II consisted of 16 patients (9 females and 7 males; mean age, 13.56 ± 1.27 years) treated using the Herbst appliance. Seventeen linear and 10 angular measurements were performed to evaluate and compare the skeletal, dentoalveolar, and soft tissue effects of the appliances using paired and Student's t-tests. Results: Both appliances were effective in correcting skeletal class II malocclusion and showed similar skeletal and soft tissue changes. The maxillary incisor was statistically significantly more retruded in the skeletally anchored Forsus FRD group (P < .01). The mandibular incisor was retruded in the skeletally anchored Forsus FRD group (−4.09° ± 5.12°), while it was protruded in the Herbst group (7.50° ± 3.98°) (P < .001). Conclusion: Although both appliances were successful in correcting the skeletal Class II malocclusion, the skeletally anchored Forsus FRD EZ appliance did so without protruding the mandibular incisors.

OBJECTIVE: This retrospective study aimed to conduct a cephalometric evaluation of the skeletal, dental and soft tissue effects resulting from treatment of adult patients presenting Class II malocclusion, performed with a Mandibular Protraction Appliance (MPA) combined with a fixed orthodontic appliance. METHODS: The sample consisted of teleradiographs obtained before and after treatment of 9 adult patients (initial mean age of 22.48 years) with bilateral Class II, division 1, malocclusion. Paired t test (p < 0.05) was applied to compare initial and final values. RESULTS: t test revealed an increase in anteroinferior facial height and posterior facial height. The dental changes include: extrusion of upper incisors, buccal inclination, protrusion of lower incisors, mesialization and extrusion of mandibular molars. Regarding the soft tissue component, there was an increase in nasolabial angle in addition to upper lip retrusion. CONCLUSIONS: The effects of treating Class II malocclusion adult patients, by means of using Mandibular Protraction Appliance (MPA) combined with a fixed appliance were mostly observed in the mandibular arch, and consisted of buccal inclination, protrusion and intrusion of incisors, and mesialization and extrusion of the molars.

Impaksi gigi terjadi karena gigi gagal untuk erupsi secara sempurna pada posisinya akibat terhalang oleh gigi lain maupun jaringan lunak atau padat di sekitarnya. Gigi yang sering mengalami impaksi adalah gigi geraham ketiga rahang bawah, gigi kaninus rahang atas, dan gigi premolar kedua. Impaksi premolar sering terjadi karena pencabutan prematur dari gig geraham desidui. Gigi premolar pertama jarang terjadi impaksi dibandingkan premolar kedua. Tujuan laporan kasus adalah untuk memaparkan penatalaksanaan perawatan untuk mengkoreksi impaksi gigi premolar pertama mandibula menggunakan alat cekat teknik Begg tanpa prosedur bedah. Pria 21 tahun mengeluhkan gigi yang berjejal pada rahang atas dan rahang bawah. Gigi kaninus desidui kiri rahang atas dan rahang bawah belum tanggal. Diagnosis pasien adalah Maloklusi Angle Klas II divisi 2 bimaksiler protrusif dengan hubungan skeletal klas II, gigi anterior maksila retrusif, disertai impaksi gigi premolar pertama mandibula kiri. Perawatan dilakukan dengan menggunakan alat cekat teknik Begg dan pencabutan gigi desidui, Kesimpulan, impaksi gigi premolar pertama mandibula dapat tercapai pada tahap pertama teknik Begg tanpa pendekatan tindakan bedah, tahap selanjutnya yang akan dicapai adalah tahap memperbaiki inklinasi aksial gigi.Treatment Of Class II Division 2 Angle Malocclusion With Mandibular Premolar Tooth Impaction Using Begg Technique. Tooth impaction is a tooth that fails to erupt perfectly to its position because of the other tooth, surrounding soft or hard tissue that blocks its eruption. Premolar often fails to erupt due to a premature extraction of deciduous molar. This case study aims to illustrate the treatment of mandibular first premolar impaction using Begg technique for fixed appliance. The experiment was conducted to a 21 year-old male patient who complained about his crowding of upper and lower teeth, also the persistence of his upper and lower left deciduous canine. The case was diagnosed as class II division 2 angle malocclusion with bimaxillary protrusion with class II skeletal relation, and maxillary anterior teeth retrusion. The left mandibular of first premolar teeth was impacted. The treatment using Begg technique has helped to fix the appliance with the extraction of the deciduous teeth. From the evaluation, it can be concluded that the treatment of impacted mandibular first premolar is achieved on the first stage of Begg technique without surgical approach. The next objective of the treatment is to correct the teeth axis.

ABSTRACT Objective: To compare Phase 1 treatment, using the Frankel 2 (FR2) or the modified Twin Block (MTB), for Class II division 1 malocclusion in children and adolescents with respect to: treatment duration, number of appliance breakages, occlusal outcome, and patient and parent perspectives. Materials and Methods: Sixty participants with a Class II division 1 malocclusion were randomly assigned to either the FR2 or MTB appliance in a two-armed parallel randomized clinical trial with an allocation ratio of 1 to 1. Time to achieve a Class I incisor relationship was the primary outcome. The number of appliance breakages was recorded. The Peer Assessment Rating (PAR) index was used to evaluate pre- and post-treatment occlusal outcome on study models. Participants completed the child OHRQoL (oral health-related quality of life), Piers-Harris, Standard Continuum of Aesthetic Need (SCAN), and Oral Aesthetic Subjective Impact Score (OASIS) questionnaires pre- and post-treatment; parents completed a SCAN questionnaire. Results: Forty-two participants completed treatment (FR2: 20; MTB: 22). Multiple imputation was used to impute missing data for noncompleters. Mean treatment duration was similar for the two appliances (FR2: 376 days [SD 101]; MTB: 340 days [SD 102]; P = .41). There were no significant differences in mean number of appliance breakages (FR2: 0.3 SD 0.7; MTB: 0.4 SD 0.8; P = .67 or mean PAR score P = .48). Patient and parent perspectives did not differ between appliances (P > .05). Conclusions: Phase 1 treatment duration, number of appliance breakages, occlusal outcome, and patient and parent perspectives were similar in 11–14 year olds with Class II division 1 malocclusion treated using the FR2 or MTB appliance.

Summary Objective To evaluate dental and skeletal effects of a new orthopaedic appliance for the treatment of Class III malocclusion in growing patients. Material and methods This retrospective cephalometric study was performed on a sample of 18 patients with a skeletal Class III malocclusion (4 males; 14 females; mean age 8.8 ± 1.5 years) treated with the Pushing Splints 3 (PS3) protocol. The control group consisted of 18 subjects (5 males; 13 females; mean age 9.1 ± 1.8 years) selected from a database of subjects with untreated Class III malocclusion. The cephalometric analysis was performed at the beginning (T0) and the end of the orthopaedic therapy (T1). Significant differences between the treated and control groups were assessed with independent samples t-test (P < 0.05). Results In the PS3 group, the post-treatment cephalometric values showed a forward displacement of the maxilla, resulting in a statistically significant increase of the SNA angle. ANPg and Wits appraisal improved significantly compared with the control group. Lingual inclination of mandibular incisors and buccal inclination of the upper incisors were significantly increased in comparison with the control group. No significant differences were recorded for backward mandibular rotation. Limitations This study presents a short-term evaluation of the treatment and the use of a historical control group. Conclusions The PS3 was effective for the treatment of Class III malocclusion in growing patients, with favourable maxillary advancement and control of the vertical skeletal relationships.

Background: Malocclusion describes anomaly conditions in orthodontics, namely occlusion abnormal conditions. The preva-lence of malocclusion in Indonesia is still high around 80%. The management of malocclusion cases needs to pay attention ear-lier compared to being alert in adulthood. The treatment that can be performed is to use an activator functional appliance to pre-vent class II malocclusion. Objective: To review how the activator functional appliance was used in the treatment of Class II malocclusion. Methods: Scientific evidence is drawn from various literature to support this paper. Conclusion: Skeletal and dental changes can be achieved with the treatment of functional devices, activators. Activators can influence mandibular growth by increasing the rate of endochondral ossification in the condyles resulting in increased mandibular length in the treatment of Class II malocclusion. The success of the functional plane depends on the patient's developmental period, skeletal disorders, and patient cooperation.

ABSTRACT Objectives To determine factors that could predict Class II/1 malocclusion patient compliance during functional treatment. Materials and Methods The sample consisted of 77 subjects (aged 11–13 years; 47% girls) presenting with Class II/1 malocclusion. Inclusion criteria were distal molar relationship, overjet greater than 5 mm, and confirmed pubertal growth spurt. Removable functional appliances (62% Twin Block [TB], 38% Sander Bite Jumping [BJ]) with built-in maxillary expansion screws were used. Follow-up period was 1 year. Patients and parents independently filled out the Child Perception Questionnaire, Parental/Caregiver Perception Questionnaire, and Family Impact Scale to assess emotional and social well-being, oral symptoms, functional limitations, parental emotions, family activities, conflicts, and financial burden as possible predictors of compliance during treatment. Sex, overjet, and appliance type were also analyzed. Results There were more noncompliant than compliant patients (55% vs 45%). Parental perception of altered emotional well-being of their children was the strongest predictor, increasing compliance odds 3.4 times (95% confidence interval [CI], 1.2–9.4; P = .017). Patients were 3.2 times (95% CI, 1.1–9.3; P = .033) more likely to cooperate with TB compared with BJ appliance. OJ ≥ 8 mm increased compliance odds 3.1 times (95% CI, 1.0–9.4; P = .044). Conclusions Parental perception of child's emotional well-being alteration, severity of malocclusion, and type of appliance are major predictors of compliance. Psychosocial issues and oral function limitations reported by children and family impact are of negligible influence.

ABSTRACT Objective: To test the hypothesis that twin-block and Mandibular Protraction Appliance-IV (MPA-IV) are not effective in improving the pharyngeal airway passage (PAP) dimensions among Class II malocclusion subjects with a retrognathic mandible. Materials and Methods: Eighty-three subjects ranging in age from 8 to 14 years were divided into four groups. Group I included 30 Class I malocclusion subjects (healthy controls); group II consisted of 16 Class II malocclusion subjects (Class II controls); group III had 16 subjects in whom Class II malocclusion was treated by MPA-IV; and the remaining 21 subjects formed group IV, whose Class II malocclusions were corrected by twin-block appliance. Lateral cephalograms recorded at the beginning of orthodontic treatment in group I subjects and at the beginning and end of follow-up/treatment with functional appliance in group II, III, and IV subjects were analyzed to determine the PAP dimensions. Paired t-test, one-way analysis of variance, and Tukey tests were applied for statistical analysis, and a P-value .05 was considered statistically significant. Results: Soft palate length was decreased significantly in group III (P < .05) and group IV (P < .001) subjects. Soft palate thickness in group IV subjects was increased significantly as compared to group II (P < .05) and group III (P < .01) subjects. The improvement in soft palate inclination in group III and group IV subjects was significant (P < .01). The oropharynx depth was increased significantly in group III (P < .05) and group IV (P < .001) subjects. The depth of the hypopharynx was increased significantly (P < .01) in group IV subjects. Conclusions: The twin-block appliance was more efficient than the MPA-IV in the improvement of PAP dimensions among Class II malocclusion subjects with retrognathic mandible.

Latar Belakang: ketidakharmonisan ukuran rahang dengan gigi merupakan salah satu bentuk etiologi maloklusi yang diturunkan dan akan mempengaruhi susunan dan posisi gigi di dalam rahang. Impaksi gigi seperti molar ketiga atau gigi kaninus sering kita temui akibat tidak adanya ruang untuk gigi tersebut erupsi dan menyusun diri di dalam lengkung yang baik. Gigi kaninus memiliki peran penting di dalam mulut, selain untuk mastikasi, gigi ini juga memiliki peran menentukan dalam estetika susunan gigi. Senyum yang menarik tidak akan didapatkan tanpa adanya gigi kaninus di dalam lengkung. Kasus impaksi kaninus dapat dirawat menggunakan teknik Begg dengan proses windowing yang dilakukan oleh ahli bedah mulut. Tujuan: membantu erupsi gigi kaninus dengan bantuan alat orto cekat teknik Begg. Kasus: laki-laki 19 tahun mengeluhkan gigi depan rahang atas protusif langit-langit tergigit oleh gigi depan rahang bawah. Diagnosis: maloklusi Angle kelas II dengan hubungan skeletal kelas I disertai kondisi berjejal di daerah anterior dan gigitan dalam. Perawatan: menggunakan alat cekat teknik Begg dan windowing dengan pencabutan dua premolar pertama rahang atas serta prosedur windo. Kesimpulan: hasil menunjukkan gigi kaninus kiri rahang atas dapat erupsi dengan baik dan bisa diposisikan ke dalam lengkung dalam 5 bulan. Background: Discrepancy in size between jaw and teeth is one of the etiology factor of malocclusion that genetically inherited and will affect teeth allignment and position within the jaw. Third molar and canine impaction frequently found because there is not enough space for theme to erupt and align themselfes in a good alignment. Canine have an important role in mastication as it is in facial aesthetic. Canine impaction can be treated with Begg technique and windowing process performed by oral surgeon. Purpose: to help impacted canine to erupt using fixed Begg appliance technique and windowing process. Case: 19 years old man complained of crowded front teeth. Diagnosis: malocclusion Angle class II, skeletal class I with crowding and deepbite on anterior segment. Treatment: using the Begg fixed appliance and windowing techniques with the extraction of two maxillary first premolars. Conclusion: the result showed that maxillary right canine erupted and can be adjusted within the line of occlusion in 5 months.

ABSTRACT Introduction: Fixed functional appliances are non-compliant solutions to Class II malocclusion treatment. The clinician, however, should be careful of unexpected complications during the therapy. Methods: 58 female adolescents who presented with Class II malocclusion due to deficient mandible were treated with Forsus Fatigue Resistant Device (FFRD) therapy until an overcorrection to an edge to edge incisor relationship was achieved. Results: Incisor relationship and overjet were corrected successfully in all the subjects. Twenty-two patients had a complications-free treatment, while several complications were encountered with the remaining 36 subjects. In particular, mandibular canine rotation and development of posterior crossbites were the most common complications, with percentages of 51.7% and 25.9% respectively. Other complications included the breakage and shearing of the extraoral tubes of the first molar bands, and excessive intrusion of the upper first molars. Conclusions: FFRD is an efficient appliance for treatment of Class II malocclusion; however, different complications were encountered during the appliance therapy. A focus on taking precautions and applying preventive measures can help to avoid such problems, reducing the number of emergency appointments and enhancing the treatment experience with the appliance.

Abstract Objective: To evaluate the “effective” temporomandibular joint (TMJ) changes (the sum of condylar modeling, glenoid fossa modeling, and condylar position changes within the fossa), and their influence on chin position in patients with a Class II division 1 malocclusion treated orthodontically with a multibracket appliance and Class II elastics (Tip-Edge) and orthopedically with a fixed functional appliance (Herbst). Materials and Methods: Two groups of successfully treated subjects were evaluated: Tip-Edge (n = 24) and Herbst (n = 40). The Bolton Standards served as a control group. Lateral head films obtained before treatment and after an observation period of 2.6 years (Herbst also after 0.6-year period) were analyzed. Results: In comparison with the Herbst and control groups, the Tip-Edge group exhibited less favorable sagittal “effective” TMJ growth and chin position changes necessary for skeletal Class II correction. Conclusions: Orthodontic therapy with a multibracket appliance and Class II elastics seems not to have any favorable sagittal orthopedic effect on the mandible, while bite jumping with the Herbst appliance has a favorable sagittal orthopedic effect on a short-time basis.

Summary Objectives The purpose of this study was to compare the results of skeletal anchorage (SAMP) and tooth- borne (TBMP) maxillary protraction followed by fixed appliance in growing skeletal Class III patients. Materials and methods Patients treated with maxillary protraction were selected and classified into two groups (SAMP: n = 19, mean age = 11.19 years; TBMP: n = 27, mean age = 11.21 years). Lateral cephalograms taken before treatment (T0), after the maxillary protraction (T1), and after the fixed appliance treatment (T2) were analysed and all variables were statistically tested to find difference between the two groups. Results Compared to the TBMP, the SAMP showed significant forward growth of maxilla (Co-A point and SN-Orbitale) and improvement in intermaxillary relationship (ANB, AB to mandible plane, and APDI) after the overall treatment (T0–T2), with no significant sagittal changes in maxilla or mandible throughout the fixed appliance treatment (T1–T2). Limitations In maxillary protraction, effects of skeletal anchorage were retrospectively compared with those of dental anchorage, not with Class I or III control. Conclusions and implications After maxillary protraction, skeletal and tooth-borne anchorage did not cause significant differences in the residual growth of maxilla throughout the phase II treatment. Orthopaedic effects with skeletal anchorage showed appropriate stability in maxilla and intermaxillary relationship even after fixed appliance treatment.

A retrospective cephalometric study of 50 consecutively completed Class II Division I malocclusion cases was carried out in order to analyse the resultant data for craniofacial features which might act as predictors for successful overjet reduction. All the patients had clinically measured overjets of between 10 mm and 15 mm at the start of treatment. The sample was subsequently divided into two groups depending on whether or not the overjet had been reduced to 4 mm or less at the end of treatment. No firm predictors were found, but the most favourable results were achieved with the Begg appliance.

ABSTRACT Objective: To explore the impact of fixed labial orthodontic appliances on speech sound production. Materials and Methods: Speech evaluations were performed on 23 patients with fixed labial appliances. Evaluations were performed immediately prior to appliance insertion, immediately following insertion, and 1 and 2 months post insertion. Baseline dental/skeletal variables were correlated with the ability to accommodate the presence of the appliances. Results: Appliance effects were variable: 44% of the subjects were unaffected, 39% were temporarily affected but adapted within 2 months, and 17% of patients showed persistent sound errors at 2 months. Resolution of acquired sound errors was noted by 8 months post–appliance removal. Maladaptation to appliances was correlated to severity of malocclusion as determined by the Grainger’s Treatment Priority Index. Sibilant sounds, most notably /s/, were affected most often. Conclusions: (1) Insertion of fixed labial appliances has an effect on speech sound production. (2) Sibilant and stopped sounds are affected, with /s/ being affected most often. (3) Accommodation to fixed appliances depends on the severity of malocclusion.

ABSTRACT Objective: This study aimed at comparing the dentoskeletal changes in patients with Class II division 1 malocclusion, treated with three types of fixed functional appliances. Methods: A sample comprising 95 patients with the same malocclusion, retrospectively selected, and divided into four groups, was used: G1 consisted of 25 patients (mean age 12.77 ± 1.24 years) treated with Jasper Jumper appliance; G2, with 25 patients (mean age 12.58 ± 1.65 years) treated with the Herbst appliance; G3, with 23 patients (mean age 12.37 ± 1.72 years) treated with the Mandibular Protraction Appliance (MPA); and a Control Group (CG) comprised of 22 untreated subjects (mean age 12.66 ± 1.12 years). Intergroup comparison was performed with ANOVA, followed by Tukey test. Results: The Jasper Jumper and the Herbst group showed significantly greater maxillary anterior displacement restriction. The Jasper Jumper demonstrated significantly greater increase in the mandibular plane angle, as compared to the control group. The MPA group demonstrated significantly greater palatal inclination of the maxillary incisors. Vertical development of the maxillary molars was significantly greater in the Herbst group. Conclusions: Despite some intergroup differences in the amount of dentoskeletal changes, the appliances were effective in correcting the main features of Class II malocclusions.

ABSTRACT Objective: To investigate changes in dental arch configuration, relationship, and malocclusion directly after Class II malocclusion treatment with a Balters bionator modified by Ascher as well as 20 years after treatment. Materials and Methods: Orthodontic dental cast analysis of 18 patients with skeletal Class II treated with a bionator without any additional fixed therapy was performed with a digital caliper at three stages: before (T0), after (T1) and 20 years after (T2) treatment. Arch perimeter and depth, intermolar and intercanine distance, overjet, overbite, sagittal molar and canine relationship, mandibular incisor irregularity (Little's index), and malocclusion (PAR index) were assessed. Results: During treatment (T0–T1), upper arch perimeter significantly increased with a significant decrease in the upper and lower arch perimeter long-term (T1–T2), whereas corresponding arch depths changed only slightly in both periods. Transverse intermolar width increased significantly during treatment, remaining almost constant from T1 to T2. Lower intercanine distance remained fairly unchanged during treatment, but decreased significantly during follow-up. Lower incisor irregularity improved slightly during treatment but increased significantly long-term. After treatment, sagittal molar relationships on both sides were improved, overjet and overbite reduced; these significant changes remained stable long-term. The peer assessment rating (PAR) index was significantly lower after treatment and increased insignificantly during follow-up. Conclusions: 20 years after bionator treatment without additional fixed appliances, the improved sagittal relationship and the reduced overjet and PAR index remained fairly stable. Long-term changes are most likely due to physiological aging processes and are not associated with bionator treatment.

ABSTRACT Introduction: Class II malocclusion, which has a significant incidence in the population, may compromise facial esthetics and the smile, as well as the masticatory and respiratory functions. Often associated with skeletal abnormalities, it severely affects and compromises quality of life. An accurate diagnosis is fundamental to prepare a treatment plan to correct dental and skeletal anomalies. Objectives: This study discusses treatment alternatives to the correction of Class II division 1 and 2 malocclusion in growing patients, using a Bionator and an extraoral appliance.

ABSTRACT Objective: To evaluate the skeletal, dentoalveolar, and soft tissue effects of the Forsus Fatigue Resistant Device (FRD) appliance with miniplate anchorage for the treatment of skeletal Class II malocclusion. Material and Methods: The prospective clinical study group included 17 patients (11 girls and 6 boys; mean age 12.96 ± 1.23 years) with Class II malocclusion due to mandibular retrusion and treated with skeletal anchoraged Forsus FRD. After 0.019 × 0.025-inch stainless steel archwire was inserted and cinched back in the maxillary arch, two miniplates were placed bilaterally on the mandibular symphysis. Then, the Forsus FRD EZ2 appliance was adjusted to the miniplates without leveling the mandibular arch. The changes in the leveling and skeletal anchoraged Forsus FRD phases were evaluated by means of the Paired and Student's t-tests using the cephalometric lateral films. Results: The success rate of the miniplates was found to be 91.5% (38 of 42 miniplates). The mandible significantly moved forward (P < .001) and caused a significant restraint in the sagittal position of the maxilla (P < .001). The overjet correction (−5.11 mm) was found to be mainly by skeletal changes (A-VRL, −1.16 mm and Pog-VRL, 2.62 mm; approximately 74%); the remaining changes were due to the dentoalveolar contributions. The maxillary and mandibular incisors were significantly retruded (P < .001). Conclusion: This new approach was an effective method for treating skeletal Class II malocclusion due to the mandibular retrusion via a combination of skeletal and dentoalveolar changes.

ABSTRACT Objectives To evaluate skeletal, dentoalveolar, and soft tissue changes between intraoral light force application and extraoral heavy force application in growing patients with skeletal Class III malocclusion. Materials and Methods: A retrospective study was conducted with pretreatment and posttreatment lateral cephalometric data from 50 subjects with skeletal Class III malocclusion. In the first group (15 boys, 10 girls; 8.67 ± 2.13 years old), each subject wore a biocreative horseshoe appliance (CHS) with two Class III elastics that exerted a force of 200 g. In the second group (13 boys, 12 girls; 8.96 ± 1.82 years old), each subject wore a Petit-type facemask and a lingual arch with hooks fixed to the maxillary arch with a total force of 700 g. Both groups of patients were instructed to wear the appliance approximately 14 hours a day, and 22 linear measurements and 8 angular measurements were evaluated. Changes of measurements from each group were compared by paired t-tests, considering a 5% significance level. Results Forward growth of the maxilla, improvement of the maxilla–mandible relationship, and upper incisor flaring were achieved in both groups without any statistically significant difference between them. Lateral cephalometric analysis also showed that U1 exposure, IMPA (Angle between mandibular plane and mandibular incisor axis), FMIA (Angle between FH plan and mandibular incisor axis), and L1-APog (Angle formed by the intersection of tooth axis of lower incisor and A-Pog line, Distance from lower incisor edge to A-Pog line) showed statistically significant differences. Lower incisors were inclined lingually in the CHS group. Conclusions During treatment of skeletal Class III malocclusion, the CHS with light Class III intermaxillary elastics therapy exhibits similar orthopedic changes to the maxillary complex and more dental changes to the lower anterior teeth compared with facemask therapy.

OBJECTIVE: To assess the effects produced by the MARA appliance in the treatment of Angle's Class II, division 1 malocclusion. METHODS: The sample consisted of 44 young patients divided into two groups: The MARA Group, with initial mean age of 11.99 years, treated with the MARA appliance for an average period of 1.11 years, and the Control Group, with initial mean age of 11.63 years, monitored for a mean period of 1.18 years with no treatment. Lateral cephalograms were used to compare the groups using cephalometric variables in the initial and final phases. For these comparisons, Student's t test was employed. RESULTS: MARA appliance produced the following effects: Maxillary growth restriction, no change in mandibular development, improvement in maxillomandibular relationship, increased lower anterior facial height and counterclockwise rotation of the functional occlusal plane. In the upper arch, the incisors moved lingually and retruded, while the molars moved distally and tipped distally. In the lower arch, the incisors proclined and protruded, whereas the molars mesialized and tipped mesially. Finally, there was a significant reduction in overbite and overjet, with an obvious improvement in molar relationship. CONCLUSIONS: It was concluded that the MARA appliance proved effective in correcting Angle's Class II, division 1 malocclusion while inducing skeletal changes and particularly dental changes.

OBJECTIVE: The objective of this study was to evaluate dentoskeletal effects in the treatment of Class II malocclusion performed with the Herbst appliance in patients at post-peak stage of growth. METHODS: The sample consisted of 16 patients with Class II malocclusion and average initial and final ages of 14.04 (ranging from 11.50 to 35.66) and 17.14 (ranging from 13.68 to 38.64) years, respectively, who were treated for an mean time of 2.52 years. Lateral cephalograms were obtained at treatment onset (T1) and completion (T2) to evaluate the effects of therapy. Initial dental casts were also used to evaluate the overjet and the anteroposterior severity of molar relationship at treatment onset. The cephalometric changes between initial and final stages were compared by means of the non-parametric Wilcoxon test. RESULTS: The results showed that the Herbst appliance did not promote significant changes in the maxillary component and the effective length of the mandible significantly increased without improving the maxillomandibular relationship. Changes in the maxillary and mandibular dentoalveolar components revealed that the maxillary incisors exhibited retrusion and lingual tipping, while the mandibular incisors presented increased protrusion and buccal tipping. The dental relationships exhibited significant improvements with the treatment. CONCLUSION: Based on the present results, it was concluded that the effects of treatment performed with the Herbst appliance in patients at post-peak stage of growth are predominantly of dentoalveolar nature.

ABSTRACT Objective: To investigate the effect of acrylic capping, treatment duration, overjet, and lower incisor inclination on the posttreatment tooth position in patients treated with 2 Twin Block (TB) appliance versions. Materials and Methods: Cephalograms of 56 patients with Class II malocclusion (21 boys, 35 girls; mean age before treatment [T1] = 12.5 years; standard deviation, 0.7) treated with a TB appliance with either acrylic capping or ball-ended clasps on lower incisors were retrospectively collected and traced. Lower incisor inclination (L1-GoGn, L1-GoMe, L1-MP) was measured at T1 and after TB appliance removal (T2). Regression analysis was performed to evaluate the effect on the lower incisor inclination of appliance type, overjet, lower incisor inclination at T1, and treatment duration after adjusting for baseline measurements. Results: Appliance design was not a significant predictor for either incisor inclination measurement (P< .05). Pretreatment lower incisor inclination was the only factor significantly associated with final tooth inclination (L1-GoGn: β = 0.57, 95% confidence interval [CI] = 0.30, 0.84, P < .001; L1-GoMe: β = 0.56, 95% CI = 0.28, 0.84, P < .001; L1-MP: β = 0.46, 95% CI = 0.17, 0.75, P = .003). There was weak evidence that treatment duration excluding L1-MP (95% CI = –1.85, –0.02; P = .045) and overjet might be associated with inclination of lower incisors at T2. Conclusions: TB appliance design with acrylic capping on lower incisors appears not to significantly control incisor proclination. Pretreatment lower incisor inclination may be significantly associated with tooth inclination after active TB treatment and should be considered in treatment planning.

In the recent years, number of adults seeking orthodontic treatment has significantly increased because of many factors including easier access to orthodontists, the availability of aesthetic treatment alternatives that make the appliance invisible, or improved awareness. Adults not only have malocclusions of different severity when they first arrive, but they also have additional restorative and periodontal considerations that need for interdisciplinary care that is well-coordinated. The two primary types of orthodontic therapy suggested for adult malocclusion are adjunctive and comprehensive. The goal of this article is to evaluate the various adjunctive orthodontic treatment methods and their treatment sequence for adult patients. This article seeks to provide readers with a better grasp of the most recent developments in adjunctive orthodontic therapy.

Background. Depending on the indication, and the age of a patient, class II division I malocclusion can be treated by a fixed or mobile orthodontic appliance, with or without teeth extraction. Case report. A treatment of a male patient, 15 years old, with dentoalveolar class II division I was described. On the base of clinical findings, study case analysis, analysis of orthopan and profile cephalogram, there were class II division I with protrusion of frontal teeth and mild crowding in lower jaw assessed. The patient was treated by fixed orthodontics appliances (SWA Roth .022") in both jaws for 18 months, with the retention period of the same length. Conclusion. Fixed ortodontic appliances are necessary when bodily movement of the teeth is indicated - in this case for cuspids distalization and retraction of incisors.

Abstract Objective: To evaluate the anteroposterior short-term skeletal and dental effects on Class II malocclusion in growing patients following treatment with functional appliances (activators or twin block), extraoral traction, or combination appliances (appliances with both functional and extraoral traction components), based on published data. Materials and Methods: A literature search was carried out identifying a total of nine prospective clinical trials. The data provided in the publications underwent meta-analysis using the random effects model with regard to SNA, SNB, ANB, and overjet. Results: All appliance groups showed an improvement in sagittal intermaxillary relationships (decrease in ANB) when compared to untreated subjects. Activators and twin block appliances accomplish this mainly by acting on the mandible (increases in SNB) while twin block appliances also seem to act on the maxilla (decrease in SNA). Extraoral traction appliances achieve this by acting on the maxilla (decreases in SNA). Combination appliances mainly act on the mandible (increase in SNB). Activators, twin block, and combination appliances also reveal a decrease in overjet, which is not the case in the singular use of extraoral traction. Conclusions: Intermaxillary changes being present in all appliance groups, anteroposterior treatment response following the use of functional appliances and/or extraoral traction in growing class II malocclusion patients is most evident in one of the two jaws (mandible for activators and combination appliances and maxilla for extraoral traction) except for the twin block group, which shows changes on both jaws.

Abstract Objective: To study the effects of cervical headgear treatment of Class II division 1 malocclusion on upper airway structures in children. Materials and Methods: Forty children aged 9.1 (7.2–11.5) years with Class II division 1 malocclusion were treated using a cervical headgear as the only treatment appliance. The headgear consisted of a long outer bow bent 15° upward and a large inner bow expanded 10 mm larger than the intermolar distance. Lateral cephalograms were taken before and after the treatment. Upper airway structures were estimated from the cephalograms. The results were compared to cross-sectional data of 80 age-matched controls with a Class I molar relationship. Results: A Class I molar relationship was achieved in all treated children. The mean treatment time was 1.6 (0.3–3.1) years. The Class II malocclusion was accompanied by a similar or wider nasopharyngeal space than in the controls but narrower oro- and hypopharyngeal spaces. The retropalatal area was widened by the treatment (P < .05), whereas the rest of the oropharynx and hypopharynx remained narrower than in the controls. Before the treatment, the mandibular plane was in a more horizontal position than in the controls, but during the treatment, it rotated to a position similar to that of the controls. Conclusion: Class II division 1 malocclusion is associated with a narrower upper airway structure even without retrognathia. Headgear treatment is associated with an increase in the retropalatal airway space.

Class II represents a considerable part of orthodontic problems to be treated in dental clinics. To correct this malocclusion, there are currently several forms of treatment. Among the functional orthopedic devices, the Herbst device has stood out due to its efficiency and practicality for being fixed and not requiring the collaboration of the patient. The purpose of this article is to present, through a clinical case report, the treatment of class II malocclusion with a modified Herbst appliance with a lower acrylic splint. The female patient initially had 11 years and 11 months, permanent dentition, mandibular retrusion and atresia of the arches. Initially, a maxillary circuit breaker and lower expander were used, followed by the Herbst appliance and finished with fixed orthodontics. At the end of the treatment, the modified Herbst appliance proved to be effective, providing a class I molar relationship, improving the patient’s profile and decreasing the space between the resting lips.

Summary Background The effects of mandibular propulsion appliances in adults have some controversial results. While some authors claim that its use in non-growing patients could produce some dentoskeletal effects, other studies indicate that Class II correction occurs only through significant dental effects. Objective To evaluate the effects in non-growing Class II patients with mandibular retrusion, promoted by the treatment with mandibular propulsion appliances and determine if they produce mandibular changes. Methods The research was carried out in nine electronic databases and additional manual searches up to July 2019. Selection criteria were no restriction was placed on date and publication language. Randomized or non-randomized clinical trials with/without control were included. They must evaluated non-growing patients with Class II malocclusion, treated with mandibular propulsion appliances; outcomes were assessed before and after treatment. Data collection and analysis Data were extracted by two independent examiners in duplicate. The ROBINS-I tool was used to assess the methodological quality of the included studies. Results Of the 2824 articles identified, 11 non-randomized clinical articles were selected for qualitative analysis and 8 for quantitative analysis. SNB (0.87°, CI 95% 0.08, 1.66), ANB (−0.82°, CI 95% −1.24 to 0.40) and Pg/OLp [2.3 to 1.2 mm (P < 0.001)] presented smallest but significant mandibular changes with some differences regarding the used appliance. The Herbst appliance showed the largest mandibular changes followed by the SUS appliance when evaluated through Ar-Pg. SNA showed non-significant changes. Overbite (−2.85. CI 95% −3.06, −2.64), Overjet (−5.00.CI 95% −5.45, −4.55) showed significant changes in all devices. Class II correction occurs through a significant labial movement of the mandibular incisors, some lingual inclination of the maxillary incisors and minor skeletal changes. Conclusions All mandibular propulsion appliances examined, showed efficiency in normalizing the Class II malocclusion in adult patients; however, changes were acquired mainly through dentoalveolar changes. Some minor mandibular forward changes was noted, mainly in patients treated with the Herbst appliance. Randomized clinical trials are needed to improve scientific evidence.
