EVALUATION OF THE CONDYLAR SHAPE AND POSITION IN PATIENTS WITH TEMPOROMANDIBULAR JOINT DISORDERS USING CONE BEAM COMPUTED TOMOGRAPHY

| Summary: | Background:
TMJ disorders are common and often self-limited in the adult population. In
epidemiologic studies, up to 75 percent of adults show at least one sign of
joint dysfunction on examination and as many as one third have at least one
symptom. The present study was conducted to investigate the position and shape
of the condyle in patients with TMD divided into two groups (a group with disc
displacement and a group with osteoarthritis) and based on their CBCT images.Materials: The present study was conducted on 45 patients (5 men
and 37 women) aged 13 to 82 (with a mean age of 37.5) known by their clinical
examinations to have TMD type II (disc displacement) and type III
(osteoarthritis). To investigate the shape and position of the condyle and the
slope of the articular eminence in the sagittal, coronal and axial planes, CBCT
images were taken from the patients' TMJ on both sides at maximum dental
occlusion.Results: The result of this study showed the lack of a normal
distribution of the data in the quantitative analysis of the horizontal
condylar position with the mouth closed (post+ante/post-ante). The compare this
indicator in the RDC and the TMD groups, revealing a significant difference
between the two (P=0.002). In group II, the condyle showed a greater tendency
toward the posterior position. A significant relationship was found between the
mediolateral condylar position (central, medial and lateral positions) and the
RDC or TMD group type (P=0.02), and the condyle showed a greater tendency toward
the lateral position in both groups. However, a significant relationship
between the sagittal shape of the condyle and the RDC or TMD group type
(P=0.02.
Conclusion: The results obtained indicate that adolescent disc
displacement and osteoarthritis can cause the condyle to change its position
and shape in the fossa. |
