Resumo: Este estudo teve como finalidades realizar uma análise comparativa entre duas técnicas radiográficas transcranianas com o auxílio do cefalostato ACCURAD-200, nas posições Padrão e Corrigida e desenvolver um gabarito que auxilie o profissional a medir os espaços articulares anterior e posterior, fornecendo informações sobre o posicionamento condilar. Foram radiografados 59 pacientes, numa faixa etária entre 18 e 35 anos, que voluntariamente se propuseram a participar deste estudo. Foi realizada uma radiografia ínfero-superior para a correção da incidência do feixe de raios X (posição Corrigida). Sobre as radiografias transcranianas foram realizados os traçados com o auxílio do gabarito e feitas as medidas lineares dos espaços articulares, usando para tal um paquímetro digital. Nossos resultados demonstraram que para ambas as técnicas empregadas o espaço articular posterior apresentou-se menor que o anterior, e que o método desenvolvido permite a avaliação do posicionamento condilar
Abstract: This study had the purpose of making a comparative analyse between transcranial radiographs utilizing ACCURAD-200 headholder in standard and corrected positions and to develop a Template to help professionals measure the anterior and posterior joint spaces and give some information about condyle position. Transcranial radiographs were taken from 59 voluntaries who participated in this study, aged between 18-35 years. A submental-vertex radiograph was obtained to correct the direction of X-rays (corrected position). A drawn was made over the films whith help of the Template and the linear measure of the joint space was made with a digital pachymeter. The results have shown that for both technics used the posterior joint space was smaller than the anterior one, and the method developed permitted the estimation of condylar positioning

Resumo: Este estudo teve como objetivo comparar, por meio de radiografias transcranianas (técnica Accurad), duas técnicas descritas na literatura para a obtenção da relação centrica e posição das cabeças da mandibula nas fossas mandibulares. Uma delas, a manipulação bilateral descrita por DAWSON em 1974. A outra, um traçado gráfico dos movimentos mandibulares no plano horizontal, denominado por GYSI, em 1910, de arco gotico, obtido por meio de um dispositivo, chamado de registro intra-oral. Foi utilizada uma amostra composta de vinte voluntarios (10 homens e 10 mulheres). Os resultados foram submetidos a uma analise estatística pelo teste não paramétrico de Wilkocson com significância de 5%. O alto valor do coeficiente de variação mostrou que a técnica que utiliza a manipulação bilateral, apresentou maiores variações quando comparada à técnica que utiliza o registro intra-oral para a obtenção do arco gótico de Gysi. A técnica que utiliza o registro intra-oral do arco gótico de Gysi posicionou as cabeças da mandíbula aproximadamente 1,5mm para tres em relação a posição das cabeças da mandíbula, quando as mesmas estavam em oclusão centrica. A tecnica da manipulação não posicionou as cabeças da mandibula na região mais superior e anterior como o preconizado pela técnica
Abstract: The purpose of this study was a radiographs investigate variations in condilar positions using two different methods of determining centric relation; bilateral mandibular manipulation advocated by DAWSON since 1974 and the arch tracing for the mandible movements in horizontal plane. This arch was denominate arch gothic in 1910 by Gysi. The sample consisted of 20 adults, 10 females and 10 males. On the basis of the analysis of the Wilkocson test (sampling error of 5%), it can be concluded that high coefficient of variation showed the most variation of bilateral mandibular manipulation method when compareted with Gysi gothic arch method. Both techniques showed condyles positioned more posteriorly and inferiorly than the mandibular position of maximum intercuspation. The distance existent between centric oclusion and the vertex of the gothic arc was approximately 1,5 mm

Повний текст джерелаMost studies of condylar movement are based on the movement of an arbitrary condylar point. As the condyle is a 3-dimensional body which undergoes complex rotations and translations in function, the movement of one point in the vicinity of the condyle may not accurately represent condylar movement. The aims of this investigation were to determine in human subjects, during open-close and excursive jaw movements, the movement patterns of arbitrary and anatomical condylar points; and whether the trajectory of a single selected point can accurately reflect the movement of the condyle. In 44 subjects, condylar point movements were recorded with an opto-electronic tracking system (JAWS3D), which recoded the position of three light-emitting diodes attached to each dental arch. The primary point, selected to represent movement of the condyle, was 15 mm medial to the palpated lateral condylar pole, parallel to the Frankfort horizontal plane. Additionally, four points were selected along orthogonal axes in the sagittal plane, and four in the horizontal plane: each was 5 mm from the primary point. In two subjects, the mandibular condyles were imaged by computerised tomography (CT) and the lateral and medial poles, most superior, anterior and posterior points of their condyles were selected. The trajectories of each point were compared for each subject for the mandibular movements listed above. Variability in both path form and dimension was noted between the subjects for all mandibular movements. For example, in an open-close mandibular movement the condylar point translation varied in the antero-posterior direction between 1.8-22.8 mm, and in the supero-inferior direction between 4.5-12.1 mm. For each subject, the pathway of each point was different in form and dimension from that subject’s other condylar points for the open-close, and ipsilateral lateral mandibular movements. For the open-close movement, in only four of the 44 subjects were the arbitrary point traces similar in form within a subject; and the tracings of each subject’s condylar points showed, on average, a 3.2 mm difference in maximal horizontal (i.e. antero-posterior) translation and 2.9 mm in maximal vertical (i.e. supereo-inferior) translation. For contralateral lateral mandibular movements, the path form and dimension in the sagittal plane of the condylar points were similar within a subject; however the lateral component showed variability in path length for the different points within a subject. The pathways of the condylar points for a protrusive movement displayed the most similarity within a subject, with an average of 0.4 mm variation in maximal horizontal or vertical displacement between each subject’s arbitrary condylar points’ tracings. The anatomical condylar points of the two subjects showed variability between and within each subject. For these two subjects the trajectories of the arbitrary condylar points moved in directions similar to the anatomical points of all movements except for the ipsilateral lateral mandibular movement, where in one subject, the arbitrary condylar points moved posteriorly, inferiorly and laterally whereas the anatomical points moved anteriorly, inferiorly and laterally. There is much variability in both form and dimension for mandibular condylar movement between human subjects. There is also considerable variability within subjects in the form and dimension of condylar point movement, whether arbitrary or anatomical, depending on the point selected. By inference therefore, a single condylar point cannot accurately reflect the movement of the mandibular condyle, except perhaps for a protrusive mandibular movement. Multiple mandibular points are therefore required to describe the motion of the condyle. In an ipsilateral lateral mandibular movement, for example, an arbitrary point may move in a completely different direction to the mandibular condyle, and so anatomically derived condylar points should be utilised to assess accurately condylar movement.

Повний текст джерелаTo evaluate the anterior-posterior (A-P)/medial-lateral (M-L) dimension, and morphology of the mandibular condyle in patients aged 18 to 65 years with Class I skeletal pattern on Cone Beam Computed Tomography scans (CBCTs). Materials and Methods: Seventy one CBCTs were evaluated using RealScan 2.0 software. The dimension was determined by points A (most anterior in the sagittal plane), P (most posterior in the sagittal plane), M (most interior in the coronal plane), L (most exterior in the coronal plane). The morphology of the condyle was evaluated in two coronal and sagittal planes, being classified as: round, flat, convex or mixed. The size of the condyle was analyzed by descriptive statistics and the morphology by frequency distribution. For the bivariate analysis, the Student’s t-test was applied. Results: Measurements were obtained for the A-P diameter of the right condyle (RC) (8.72mm ± 1.25mm) and the left condylar (LC) (8.50mm ± 1.50mm), the M-L diameter of the RC (19.24mm ± 2.03mm) and the LC (18.97mm ± 1.87mm). There were significant differences in the male M-L dimension of the LC compared to the female (p=0.002). The most prevalent morphology of RC (35.21) and IQ (23.94) in the coronal plane was round.. Conclusion: The A-P dimension of the right and left condyle is similar in both genders; however, there are differences in the M-L dimension of the left male condyle. The most prevalent morphology of the right and left condyle was round in the sagittal plane with the exception of the coronal plane.

Повний текст джерелаAdolescent internal condylar resorption (AICR) is a progressive disease that affects the temporomandibular joint, which could result in malocclusion, facial deformity, TMJ dysfunction and pain. The onset of this disease occurs between 10 and 15 years, being more common in female adolescents. These patients have characteristic clinical signs such as: increased occlusal and mandibular plane angle, progressive mandibular retrusion, and Class II malocclusion with or without open bite. In imaging studies (computed tomography and magnetic resonance imaging), internal resorption of the condyles and articular disc displacement of the TMJ are observed. Given the difficulty in determining the cause of the AICR and the importance of eliminating pain and improving masticatory function, this study is proposed to evaluate the changes brought to the mandibular positioning and it s long-term stability and the painful symptoms, using the protocol treatment: surgical repositioning of the articular disc and orthognathic surgery performed on the same surgery. In this retrospective study, we assessed the lateral cephalograms obtained at initial assessment (T1), pre-surgery (T2), immediately after surgery (T3), and longest followup, with at least one year post-surgery (T4) and questionnaires of pain and mandibular function of a sample of 24 Class II patients (20 females and 4 males) diagnosed with AICR, wich underwent the treatment protocol: surgical repositioning of the TMJ articular disc simultaneously with orthognathic surgery. The treatment protocol used was fairly positive, since the long-term stability was acquired and a significant improvement in levels of pain and jaw function were achieved. The treatment of patients diagnosed with AICR and treated with the proposed protocol, shows that the procedure is very stable and acts directly on a gain in pain reduction.
A reabsorção condilar interna no adolescente (RCIA) é uma doença progressiva que afeta a articulação temporomandibular (ATM) e que pode resultar em maloclusão, deformidade facial, disfunção de ATM e dor. O aparecimento desta doença ocorre entre os 10 e os 15 anos, sendo mais freqüente em adolescentes do sexo feminino. Esses pacientes apresentam sinais clínicos característicos como: ângulo do plano oclusal e do plano mandibular aumentados, retrusão progressiva da mandíbula e maloclusão Classe II, com ou sem mordida aberta. Nos exames de imagem (tomografia computadorizada e ressonância magnética), observa-se reabsorção interna dos côndilos e deslocamento dos discos articulares da ATM. Tendo em vista a dificuldade em determinar a causa da RCIA e a importância em eliminar a dor e melhorar a função mastigatória, este estudo se propôs a avaliar as alterações promovidas no posicionamento mandibular, a sintomatologia dolorosa e a estabilidade do tratamento da RCIA, utilizando o protocolo de tratamento (Dr. Larry M. Wolford) em pacientes adolescentes submetidos a cirurgia de reposicionamento do disco articular e cirurgia ortognática, realizadas no mesmo ato cirúrgico. Neste estudo retrospectivo, foram avaliadas as telerradiografias laterais adquiridas na avaliação inicial (T1), pré-cirúrgica (T2), pós-cirúrgica imediata (T3) e de maior acompanhamento, com pelo menos um ano pós-cirurgia (T4) e questionários de dor e função mandibular de uma amostra de 24 pacientes com maloclusão de Classe II (20 do sexo feminino e 4 do sexo masculino) diagnosticados com RCIA, os quais foram submetidos ao protocolo de tratamento composto pela cirurgia de reposicionamento do disco articular da ATM concomitantemente à cirurgia ortognática. O protocolo de tratamento utilizado mostrou-se bastante positivo, uma vez que a estabilidade foi adquirida e uma melhora significativa nos níveis de dor e função mandibular foram atingidos. O tratamento dos pacientes diagnosticados com RCIA, através do protocolo de tratamento proposto, é um procedimento estável e atua diretamente em um ganho na redução da dor.

The aim of this study was to evaluate the healing of the mandibular condyle fracture and facial symmetry in rats treated with MTX. 100 Wistar male rats undergone surgery using an experimental model of mandibular condyle fracture of the right side. The rats were distributed in four groups and received the following treatments: Control Saline (1 ml/week); Dexamethasone dexamethasone (0,15mg/kg); MTX Low dose MTX (3 mg/kg/week); MTX High dose MTX (30 mg/kg). Animals were sacrificed at one, seven, 15, 30 and 90 days postoperatively (n=5). Animals body weight were recorded. Blood has been taken to provide the biochemical analysis of total proteins and alkaline phosphatase. Radiographic axial exams from the heads were provided to cephalometric analysis. Linear measures of jaw and mandible, as well as angular measures of the mandibular deviation were done. The samples were histologically processed and coronal sections were obtained. Quantitative data were submitted to statistical analysis (=0,05). The animals regained body weight over the time, except in MTX High dose group. Total protein serum levels demonstrated the increase in initial periods and the alkaline phosphatase levels showed decrease in the periods of bone callus formation. There was reduction in the mandibular length and also changes in the jaw and progressive deviation in the mandible in relation to the skull basis in the MTX High dose group. The histological analysis revealed that there were repair of the bone and temporomandibular joint although in the MTX High dose group there was a delay in this process, in wich there was deviation of the condyle and one specimen was fibrous ankylosis. Histomorphometry revealed that the new bone formation area was lower in MTX High dose group. It was concluded that treatment with high dose MTX had a deleterious effect on facial symmetry of rats submitted to fracture of the condylar process and damaged the bone callus formation and repair of the temporomandibular joint, with possible induction of fibrous ankylosis.

Повний текст джерелаThe aim of this study was to evaluate the condylar position in patients with articular TMD before and after treatment with occlusal splints by cone beam computed tomography. Were evaluated and treated 22 patients with signs or symptoms of TMD joint, screened in the Clinical School of Dentistry, Universidade Estadual de Montes Claros, who met the inclusion and exclusion criteria. The diagnosis of TMD was conducted with the Research Diagnostic Criteria for Temporomandibular Disorders (RDC / TMD). The patients were subjected to therapy for occlusal splints for 90 days. Three cone beam computed tomography scans in the region of the TMJ right and left, were being conducted: the first at the beginning of treatment, with the patient in the position of MIH (G1); the second after 90 days of treatment with the patient occluding the occlusal splint (G2); and the third after 90 days of treatment with the patient in the position of MIH (G3). Measures of joint spaces were performed in front, superior and posterior in sagittal cuts of the TMJ. The collected data were analyzed statistically using the t test: paired samples at the 5 % significance level for the comparison between two groups. In the comparison between G1 and G2 and between G2 and G3, a statistically significant increase for the superior joint space and the posterior, but there was no statistically significant difference in the front joint space. For the comparison between G1 and G3, was observed a statistically significant increase in front joint space and superior, and not significant in the posterior joint space. The results of the analysis of the RDC / TMD showed a significant improvement in pain reported by patients and statistically significant increase in maximal mouth opening at the end of therapy with occlusal splints. Considering the method used and the sample data, it was possible to increase the space between the condyle and the articular cavity during use of occlusal splints and also that this therapy improved pain reported by patients and increased range of motion of mandibular opening.

Повний текст джерелаDuring the development of occlusion, malocclusions installation may result in disharmony dento facial nature and various severity, can cause changes in craniofacial development, among the structures involved in the temporomandibular joints mandibular (ATM), may suffer some influence, thus the evaluation of this region, the morphological and functional aspect, constitutes topic of interest, when taken into account the functional aspects of occlusion. The relationship between form and function, both the heads of the jaw, as well as the outline of the mandibular fossa with malocclusion remains controversial and is not fully understood, but the literature on the subject shows correlation between the installation of malocclusions and modifications to this system, even if some changes are not of statistical order and samples from individuals at an early age, they can compromise the proper development in adults and even young adults. With the intent of this study was to evaluate the heads of the jaw as the volume and surface of the right and left sides, crossed and uncrossed, the selected sample of 20 subjects with unilateral posterior cross bite, aged from 06 to 09 years old, using computed tomography cone beam, images obtained by a device model i-Cat, being used in reformatting and manipulation of images the computer program - NemoCeph 3D® version 11.5. The proposals measurements for this study, we used the paired t-test of Student for samples with normal distribution. The observation of the tables and their graphs, we can see that the comparison between the right and left sides, and crossed and uncrossed the heads of the mandible in relation to the volume and surface, there are numerical differences between them, but can not be observed differences statistically significant, this sample specifies the methodology used for this study. Thus it was concluded that the Unilateral Posterior Crossbites the heads of the jaw in both its volume and its surface showed no statistically significant differences

Повний текст джерелаMandibular surgery such as distraction osteogenesis can generate anatomical modifications in the temporomandibular joint (TMJ) discs. The resulting stress modifications can be at the origin of a temporary or permanent disc dislocation with degeneration and may cause severe oral and facial pain or masticatory dysfunctions. The aim of this work was to predict stress modification in the temporomandibular joint (TMJ) after mandibular symphyseal distraction (SD). This surgical procedure is used to resolve dental crowding on the mandibular dental arch.In order to study the potential impact of such a surgery on TMJ discs a three-dimensional finite element analysis of a complete mastication model was performed. Geometric data were obtained from MRI and CT scans of a healthy male patient and each component was meshed individually. The distraction was performed on the model with a 10 mm expansion after simulation of a surgical vertical osteotomy line in the mandibular midline region. The geometry and mesh of the bone callus were generated. The bone callus was modeled as a strengthened region characterized by a Young's modulus corresponding to consolidated bone to predict the long-term biomechanical effect of SD. Boundary conditions for jaw closing simulations were represented by different jaw muscle load directions. The von Mises stress distributions in both joint discs and condyles during closing conditions were analyzed and compared before and after SD. Contrary to usual analyses, no symmetry was used, and the whole mandible was analyzed in order to exhibit potential asymmetries. Stress distribution was similar in discs and on condylar surfaces in the pre- and post-distraction models. The outcomes of this study suggest that anatomical changes in TMJ structures should not predispose to long-term tissue fatigue and demonstrate the absence of clinical permanent TMJ symptoms after SD

Повний текст джерелаThe purpose of this work was the implementation of a methodological chain for bilateral sagittal split osteotomy (BSSO) virtual planning and its transfer in the operating room. In the first part of the work, usual methods for planning BSSO are exposed. Usually realized from plaster models on articulator, the planning and the occlusal surgical guides production are at risk of temporo-‐mandibular functional disorders. The quality of the functional result depends on the correct positioning of the mandibular condyle, considered as a skeletal stability element. An assessment of the maxillofacial surgeons practices was realized regarding intra-‐operative condyle positioning. Using a condylar positioning device (CPD),less frequently employed than the empirical method, meets an acceptable benefit/risk balance. This method was virtually reproduced through various steps of the methodological chain described. Computerized innovative techniques for three-‐dimensional acquisition, design and manufacturing were used. In the second part of the work, the methodology of each step of the chain was presented and estimated, either on cadaveric subjects, or on patients. The aim was to demonstrate the feasibility of the whole chain. The “acquisition and surface extraction” step pointed the issue of artefacts due to dental or orthodontic metallic devices. Ninety % of the obtained meshes were satisfactory, allowing not to use plaster models. The “virtual surgical planning” step allowed reproducing the usual method and showed great interest in bone interferences prevention. The “modelling and printing of the surgical guide” step described the stages of occlusal and condylar positioning device (OCPD) invention. Its technical characteristics, its methods of manufacturing by 3D printing, and its intraoperative use were specified. The step “OCPD evaluation” showed the method feasibility and the clinical, technical and biological equivalence of this custom-‐made medical device as compared to those used in the usual method. Finally the condylar position obtained with this device was estimated in a preliminary clinical study and compared with the literature. Thanks to the OCPD, we showed the possibility of transferring in the operating room an OSBM virtual planning controlling condyles position

Purpose: This study was conducted to quantify mandibular condylar resorption in patient with the temporomandibular joint degenerative disease with condylar volume and HU value. Materials and Methods: This study was a cross-sectional case-control study, Taiwanese adults patients (18-45 years old, 70 females and 20 males) were grouping in two groups base on image criteria for RDC/TMD: TMJ-DJD group (60 patients) and non TMJ-DJD group (30 patients). CBCT image and ITK-SNAP software were used to evaluate volume, HU value and condylar morphology between two groups. Age, gender, mandibular deviation were also recorded to assess the association between these variations. Results: Condylar volume of TMJ-DJD group is smaller (P <.001) than non TMJ-DJD group, especially in the late stage of TMJ-DJD. HU value is not different between TMJ-DJD and non TMJ-DJD group (P=.257), but it increased in the late stage of TMJ-DJD. The more mandibular asymmetry, the lesser condylar volume and the higher HU value in the deviated side of TMJ-DJD group. Gender influence condylar volume and HU value while age is negligible in our study group. Conclusion: The results suggest that the current quantification technique using condylar volume and HU value can represent the severity of TMJ-DJD. The current method could be a benefit to initially evaluation patient’s TMJ or follow up patients who is undergo a treatment that could affect mandibular condyle.

Повний текст джерелаThe temporomandibular joint (TMJ) is the main connection between the skull and the mandible and is the most complex and functionally requested joint in the human body. This joint is not immune to changes, whether these are caused by mechanisms intrinsic to the stomatognathic system, on through accidents or even surgery for correction of the jaws. The most common alteration in TMJ after orthognatic surgery is condylar resorption. This narrative review of the literature aimed to assess the relationship between orthognatic surgery and condylar resorption as well as the characteristics of this pathology. The literature shows a relationship between orthognathic surgery and condylar resorption, most frequently associated with the type of osteotomy and the type of postoperative fixation. However more case-control studies with larger sample sizes should be performed to support this evidence.
