Full textAbstract:
Orthodontic treatment is a long-lasting and difficult process which requires compliance between doctor and patient. It is a complex process, duration of which increases with transition from temporary to permanent bite. The main factor of orthodontic treatment is the cost of the procedure because there are new and modern tools and equipment. There are several ways to reduce orthodontic treatment: in the period of changing teeth, these are methods of corrective teeth extraction, based on the difference in the mesial-distal dimensions of milk (temporary) molars and method Hotz, replacing them with premolars, is the removal of individual healthy teeth according to the chosen treatment strategy bite disorders, compact osteotomy, the use of various physiotherapeutic methods without drugs and with the use of agents that promote bone tissue relaxation in combination with active physical factors and others related to the improvement of orthodontic appliances. The most significant factor in orthodontic treatment, resulting in a number of cases of interrupting the correction process, is its duration, up to 2-3 years in the period of permanent teeth. One more serious problem in orthodontic treatment associated with strategic choice of extraction or nonextraction method of treatment is stability of received clinical results. Only therapeutic prognosis of stabile morphological and functional clinical advantages of orthodontic treatment can be a basis for choice of orthodontic treatment management with the use of extraction of some healthy teeth. So, the problem of orthodontic treatment both in children and adults is one of the most important in bite correction. That’s why surgeries are involved in complex orthodontic treatment. Extraction of some permanent teeth is coordinated decision between patient and orthodontist considering the number of factors. Orthodontist must be theoretically competitive in the peculiarities of child’s organism. Despite the use of surgery of healthy teeth in orthodontic treatment in European and scientific literature the choice of extraction and nonextraction method of treatment has been yet discussable. New diagnostic methods, modern orthodontic appliances, national peculiarities of face and other features are needed for correct European thought in orthodontist.

The success of orthodontic treatment quite often depends on cooperation between the orthodontist and the dental surgeon. An integrated approach, including orthodontic treatment of dento-maxillary anomalies in combination with using the latest surgical techniques can provide quick defect correction of the maxillofacial region and ensure better stability of the results achieved; in most cases of teeth crowding, there is no alternative to the removal of the third lower molars. The purpose of this study was to analyze the surgical interventions performed on for surgical extraction of wisdom teeth for orthodontic reasons and the approach to their choice. Materials and methods. During 2016-2020 years, 158 patients were subjected to 241 surgical interventions for surgical extraction of the third lower molars for orthodontic reasons. We performed on 160 (66.4%) standard operations of atypical tooth extraction, 43 (17.8%) germectomies and 38 (15.8%) coronectomies. The patients' age ranged from 12 to 26 years. All patients were examined by applying the standard technique including orthopantomogram. In cases then it was impossible to clearly assess the ratio between the roots of the wisdom tooth and the mandibular canal as a result of the superposition of their projections on the obtained pantomograms, we used computed tomography. Based on the data obtained from the examination of the patient, the optimal safest surgical intervention was chosen for removal: the surgical extraction of the wisdom tooth, germectomy, or coronectomy. Conclusions: 1. Operations on surgical extraction of the lower wisdom teeth require mandatory planning and an individual approach to each patient based on a thorough preliminary examination. 2. In cases when it is impossible to clearly assess the ratio between the roots of the wisdom tooth and the mandibular canal as a result of overlapping their projections on the pantomograms, patients are recommended to undergo computed tomography, and then based on the assessment of CT findings to determine the topographic and anatomical relationship of the mandibular canal and roots. 3. The operation of surgical extraction of the lower wisdom tooth can be performed as a standard operation, germectomy can be recommended for patients with underdeveloped roots, coronectomy is a good option when the roots of the wisdom tooth are very close to the mandibular canal.

Complete correction of Class II malocclusion in an adult patient is not an easy task. In a case with large skeletal discrepancy, orthognathic surgery is the treatment of choice. However, in case of slight or borderline discrepancy, other treatment options are available, such as tooth extractions and miniscrews. Intermediate cases can also be treated with Class II correctors and elastics. This clinical report presents the orthodontic treatment of a 25-year-old female patient with Class II malocclusion. Clinically, the maxilla was well positioned, and the mandible was slightly retruded. The patient presented vestibularized upper incisors, well-positioned lower incisors and opted for a more aesthetically attractive orthodontic appliance. The treatment plan included teeth leveling and aligning in both arches, Class II correction, establishment of Class I molar and canine relationships, correction of overjet and overbite, midline correction, and improvement of facial and dental aesthetics. The orthodontic treatment consisted of removable Invisalign aligners and Class II elastics.

OBJECTIVE: Evaluate axial mesiodistal inclinations of the mandibular molars in orthodontically treated cases, analyzing whether inclusion of second mandibular molars in treatment mechanics has any influence on final and postretention molars angulations. METHODS: The sample comprised 150 panoramic radiographs of 50 patients. Patients were treated with extraction of four first premolars and divided into 2 groups: Group 1 comprised 25 subjects without inclusion of mandibular second molars during orthodontic treatment, whereas Group 2 comprised 25 subjects with inclusion of mandibular second molars. Panoramic radiographs at three observation times were evaluated: pretreatment, posttreatment and postretention. The statistical analysis included one-way analysis of variance (ANOVA) for intragroup evaluation and independent t-tests for intergroup comparisons. RESULTS: Intragroup analysis demonstrated significant uprighting of mandibular first and second molars during treatment in Group 2, which remained stable during the postretention stage. Intergroup comparison demonstrated that Group 2 presented first and second molars significantly more uprighted in relation to Group 1 in both post-treatment and postretention stages. CONCLUSIONS: It was concluded that inclusion of mandibular second molars in the orthodontic mechanics is relevant not only to correct the angulation of these teeth, but also to aid mandibular first molars uprighting.

ABSTRACT Objective: To evaluate the skill of orthodontists and oral/maxillofacial surgeons (OMFS) in providing a prognosis of mandibular third molars spontaneously erupted, through follow-up panoramic analysis. Methods: 22 orthodontic patients treated without extraction, presenting spontaneously erupted mandibular third molars (n = 44) were analyzed through panoramic serial radiographs. The first panoramic radiograph was obtained just after orthodontic treatment (PR1), in patients aging from 13 to 19 years. A second panoramic radiograph (PR2), was obtained in average two years later. The radiographs were randomly analyzed by 54 specialists, 27 orthodontists and 27 OMFS, to obtain the opinion about the approach to be adopted to these teeth in PR1. Then, another opinion was collected by adding a serial radiograph (PR1+2). Results: The concordance of the answers was moderate for OMFS (Kappa 0.44; p< 0.0001) and significant for orthodontists (Kappa 0.39; p< 0.0001). In the analysis of the first radiograph (PR1) of the spontaneously erupted molars, OMFS indicated extraction in 44.5% of cases, while orthodontists indicated in 42%, with no difference between groups (p= 0.22). In PR1+2 analysis, orthodontists maintained the same level of extraction indication (45.6%, p= 0.08), while surgeons indicated more extractions (63.2%, p< 0.0001). Conclusions: Orthodontists and OMFS were not able to predict the eruption of the third molars that have erupted spontaneously. Both indicated extractions around half of the third molars. A follow-up analysis, including one more radiograph, did not improve the accuracy of prognosis among orthodontists and worsened for OMFS.

Full textAbstract:
In planning orthodontic cases that include extractions as an alternative to solve the problem of negative space discrepancy, the critical decision is to determine which teeth will be extracted. Several aspects must be considered, such as periodontal health, orthodontic mechanics, functional and esthetic alterations, and treatment stability. Despite controversies, extraction of teeth to solve dental crowding is a therapy that has been used for decades. Premolar extractions are the most common, but there are situations in which atypical extractions facilitate mechanics, preserve periodontal health and favor maintenance of the facial profile, which tends to unfavorably change due to facial changes with age. The extraction of a lower incisor, in selected cases, is an effective approach, and literature describes greater post-treatment stability when compared with premolar extractions. This article reports the clinical case of a patient with Angle Class I malocclusion and upper and lower anterior crowding, a balanced face and harmonious facial profile. The presence of gingival and bone recession limited large orthodontic movements. The molars and premolars were well occluded, and the discrepancy was mainly concentrated in the anterior region of the lower dental arch. The extraction of a lower incisor in the most ectopic position and with compromised periodontium, associated with interproximal stripping in the upper and lower arches, was the alternative of choice for this treatment, which restored function, providing improved periodontal health, maintained facial esthetics and allowed finishing with a stable and balanced occlusion. This case was presented to the Brazilian Board of Orthodontics and Dentofacial Orthopedics (BBO), as part of the requirements for obtaining the BBO Diplomate title.

ABSTRACT This manuscript describes the treatment of a 27-year-old patient who was previously treated with two maxillary first premolar extractions. The patient had skeletal Class III malocclusion, Class III canine relationship, anterior crossbite, and a concave profile. As the patient refused orthognathic surgery, a miniplate was used on the right side of the lower arch as an anchorage unit after the extraction of mandibular first premolars, aiding the retraction of anterior teeth. At the end of treatment, anterior crossbite was corrected, in which first molars and canines were in a Class I relationship, and an excellent intercuspation was reached. Furthermore, patient's profile remarkably improved as a result of mandibular incisor retraction. A 30-month follow-up showed good stability of the results obtained. This case was presented to the Brazilian Board of Orthodontics and Dentofacial Orthopedics (BBO) as one of the requirements to become diplomate by the BBO.

Full textAbstract:
Background: Supernumerary teeth are present in 0,2-3% of the population. Multiple supernumeraries are often associated with syndromes such as cleidocranial dysplasia and Gardner's syndrome. They often hinder the permanent eruption’s teeth, causing cavities, periodontal lesions, pulp necrosis, and in some cases follicular cysts. Reactive lesions such as fibroma, local fibrous hyperplasia, pyogenic granuloma, and peripheral ossifying fibroma are frequent gingival lesions. Materials and Methods: We reported a case of a 9 years old patient with the missed eruption of a permanent element caused by a supernumerary tooth, associated with an exophytic palatine lesion. The deciduous incisor was still present and the supernumerary included. It was decided to proceed with the extraction of the deciduous and to wait for scheduling checks every two months. After a few months, the conoid shape supernumerary tooth erupted in the maxillary arch, so a fixed orthodontic therapy was performed to create the space for the central incisor’s eruption. Results: After a few months, the tooth began to erupt in the arch thanks to orthodontic traction. The patient was instructed to correct and specific oral hygiene maneuvers to lower the plaque index and try to reduce gingival hypertrophy. Conclusion: Supernumerary teeth often hinder the eruption and development of the related permanent tooth causing localized periodontal problems. Corrective fixed orthodontics requires more strict oral hygiene to avoid periodontal complications.

Gigitan terbuka merupakan maloklusi yang bercirikan tidak terdapatnya tutup menutup gigi rahang atas dan bawah, dapat terjadi pada regio anterior maupun posterior dan dapat melibatkan dental maupun skeletal. Maloklusi ini memerlukan ketelitian dalam penentuan diagnosis dan perawatan untuk mendapatkan hasil perawatan yang baik dan kestabilan jangka panjang. Tujuan penulisan studi kasus ini adalah untuk menginformasikan manajemen pasien dengan gigitan terbuka tipe skeletal. Pasien pria berumur 19 tahun datang ke Klinik Ortodonsia FKG UGM dengan keluhan utama gigi depan yang tidak rata dan tidak dapat digunakan untuk menggigit. Pemeriksaan klinis menunjukkan pasien memiliki kebiasaan menelan dengan menjulurkan lidah. Pemeriksaan model studi menunjukkan maloklusi Angle kelas I dengan gigitan terbuka anterior dari regio premolar kedua kanan ke kiri sebesar 10,7 mm disertai malposisi gigi individual dan pergeseran garis tengah rahang bawah ke kiri. Pemeriksaan sefalometri menunjukkan relasi skeletal kelas II dengan retrusif bimaksila, rotasi mandibula searah jarum jam dan gigitan terbuka skeletal. Pasien menolak tindakan bedah ortognatik sehingga dilakukan perawatan ortodontik kamuflase. Perawatan diawali dengan latihan miofungsional untuk melatih cara penelanan yang benar dilanjutkan dengan perawatan ortodontik teknik straightwire dengan pencabutan empat gigi molar pertama. Penutupan gigitan terbuka menggunakan elastic box anterior. Hasil evaluasi menunjukkanpengurangan besar gigitan terbuka dari 10,7 mm menjadi 1,25 mm. Kesimpulannya elastic box anterior dapat digunakan untuk mengoreksi gigitan terbuka yang etiologinya melibatkan intrusi gigi anterior. Skeletal Anteroposterior Open Bite Treatment with Straight Wire Technique. Open bite is a malocclusion with characteristic no overlapping between maxillar and mandibular teeth. This malocclusion may occur in anterior or posterior region and involved dental or skeletal. This malocclusion needed precise diagnosis and treatment to get a good treatment result and long term stability. The aim of this case report was to inform management of patient with skeletal open bite. A 19 years old male came to orthodontic clinic Faculty of Dentistry Gadjah Mada University with the chief complaint anterior crowding, and anterior teeth cannot be used to bite. Clinical finding showed patient had tongue thrusting habit. Study model analysis showed class I Angle malocclusion with 10.7 mm anterior open bite from right second premolar to left second premolar, with individual teeth malposition and mandibular midline shifting to the left. Cephalometric finding showed class II skeletal relationship with bimaxillar retrusive, clockwise mandibular rotation and skeletal open bite. This patient refused orthognatic surgery, so he received camouflage orthodontic treatment. This treatment was started with monofunctional exercise to correct the swallowing action then continued with straight wire orthodontic treatment with four first molar extractions. Anterior box elastic was used to close the bite. Evaluation result showed open bite was decreased from 10.7 mm to 1.25 mm. The conclusion was anterior box elastic could be used in open bite correction that involved anterior teeth intrusion as an etiology.

The use of Corrective Orthodontics to modifying dental aesthetics, has been increasingly effective in modifying and improving the profile of patients. Objective: Review the literature on the treatment of Cl I malocclusions with severe dental crowding and to report a clinical case performed in the dental clinic of a private educational institution. Methodology: After dental extraction and fixed orthodontic appliance treatment, the facial and dental aesthetics patient evolution with the diastema presence between dental elements 11 and 21 and supernumerary elements. The case was treated in two phases, with the aim of correcting the dental crowding. In the first phase, the first premolars and a supernumerary tooth were extracted, to initiate the isolated canine retraction and, later, the space closures by means of the retraction of the incisors. In the second phase, after the closure of spaces, the intrusion and molarization verticalization phase was started. For the subject review in case, articles were searched in the Pubmed databases, Lilacs and Scielo and selected 8 articles between the years 2010 and 2019.Results and Conclusions: It was observed that the exodontia provided the necessary spaces for the alignment and leveling of the teeth and the intrusion and mandibular rotation of the molars allowed the mandible to rotate counter clockwise, reducing the convex profile of the patient. At the end of the treatment, a facial response was observed according to the mechanics employed and significant improvement in the dental, facial aesthetics and, consequently, social improvement of the patient.
