“…This results was similar with the results of Gateno et al In patients with disk displacement the head of the condyle was located more posterior and superior in the mandibular fossa when compared with normal individual.Burke et al [6] found that the vertical plane and the Sjs in the long face patients were less than short face patients and there was no correlation between facial morphology and anterior-posterior position of the condyle in glenoid fossa. Katsavrias et al [5,9] reported that the Sjs is smaller in class III group who had closer vertical relationship between the condyle and the roof of the fossa.In our study Sjs was greater in symptomatic TMD male patients, when compared to Dalili, et al [9,5,10] who found that Sjs was the largest space in class I skeletal category [5] . Cohlmia et al [9,10] and Seren et al [10] stated that anterior position of the condyle was a more frequently positioned in the class III patients with smaller Ajs in the class III patients than class I.…”

The loss of the thick posterior band of the disc, normally interposed between the superior surface of the condyle, and the height of the articular fossa would allow for superior condylar settling.…”

Temporomandibular joint (TMJ) is a unique joint. The dimension joint space is determined by the optimal Condylar position. Conventional radiographs cannot exactly show the relationship hence MRI and CT are being used frequently for imaging of TMJ. CBCT has recent advancement into technology especially in this field as helped to analyse the TMJ in more comphrehensive manner. The aim of this study is to assess the position of condyle in TMJ with patients of TMDs. The importance of relationship between condyle and glenoid fossa remains controversial. The CBCT utilizes less radiation and as higher resolution than normal CT. The position of condyle in the glenoid fossa is measured with high accuracy using CBCT technique for reconstruction and imaging of the TMJ. It provides reliable and accurate images. The study was designed to compare the condylar morphology in symptomatic and asymptomatic patients with TMD s.

Purpose: The aim of this comparative observational study is to evaluate and compare the size and position of the condyle among male and female patients with different skeletal patterns in the anterior‐posterior dimension using cone beam computed tomography (CBCT) images.Materials and Methods: CBCT images of 120 patients, all prepared for other treatment purposes under the same conditions, were included in the study. The patients were classified into three groups—class I, class II, and class III—based on ANB angles and Wits analysis. The size of the condyle was measured in terms of width, height, and length. The position of the condyle was assessed by measuring the superior joint space (SS), anterior joint space (AS), and posterior joint space (PS) on the right and left sides separately. The measurements and results were analyzed using analysis of covariance (ANCOVA) and Bonferroni analysis. A statistical significance level of p < 0.05 was considered.Results: The study found no statistically significant differences in the size of the SS and AS (p = 0.481 and p = 0.392, respectively) across different skeletal patterns. However, the size of the PS was significantly greater in class I subjects compared to class III subjects (p = 0.015). There were no statistically significant differences in condyle height and width among the different skeletal patterns (p = 0.367 and p = 0.720, respectively). In contrast, condyle length was statistically significant in class II individuals (p = 0.002) and was the lowest among the other skeletal pattern groups.Conclusions: Based on the results obtained, class I individuals have lower PS values compared to class III individuals. Additionally, class II individuals have shorter condyle lengths compared to those in class III and class I.

To assess condylar position using Gelb’s grid in subjects with different malocclusion. Pre- treatment lateral cephalogram of 45 subjects (aged above 18yrs) were taken and equally divided in three groups, Group I(skeletal Class I malocclusion), Group II-(skeletal Class II malocclusion) and Group III (Class III malocclusion) based on three Cephalometric parameters (ANB, Yen angle and Wits appraisal). Condylar position in relation to glenoid fossa was assessed with Gelb’s grid. For Group I condyle was positioned normally (4,7) in 86.66% of subjects and was positioned posteriorly (5,8)13.33% of subjects. For Group II condyle was displaced posteriorly (5,8) in 86.66% of subjects and in normal position (4,7) for remaining subjects. For Group III subjects condyle was again found in posteriorly displaced 66.66% of subjects and normally positioned in rest of subjects. It can be suggested that the condylar position showed variability in three malocclusion groups. Class I malocclusion group with no skeletal discrepancy was associated with more symmetric normal condylar position than malocclusion groups with skeletal discrepancy (Class II and Class III).
