OBJECTIVES: To evaluate the relationship between internal derangement and morphological features of the temporomandibular joint by comparing joint morphology between patients with ID and control patients.
METHODS: The current study prospectively is evaluated the cone-beam computed images of 106 ID patients and 122 patients with asymptomatic joints; recorded angular and linear measurements. The relationships between these measurements and ID are investigated; the differences between the two groups using paired t tests.
RESULTS: There were significant differences in the values of articular slope and the condyle height/glenoid fossa depth (CH/GFD) ratio between patients in the ID and control groups (p < 0.05). There was also a relationship between these parameters and the gender of patients with ID. The condylar position was posterior in the ID group.
CONCLUSION: Posteriorly and superiorly located condyles with an increased CH/GFD ratio, condyles located eccentrically, and a steeper posterior slope may be risk factors for ID.
