Objective: To evaluate, by magnetic resonance ımaging (MRI), the effects of surgically assisted rapid maxillary expansion (SARME) on the temporomandibular joint (TMJ) disc position.
Methods: Patients with maxillary transversial discrepeancies treated SARME analyzed prospectively. The magnetic resonance imaging assessments of the TMJ were obtained before SARME operation and after expansion process. Retention period, gender and presence of wisdom teeth were the predictor variables. Disc position index (DPI) values were calculated and analyzed as an outcome variable.
Results: The study included 13 subjects (4 male, 9 female) with a mean age of 19.5±2.3 years. After treatment there was excess changing position seen in three articular disc relative the condyle in three patient. Retention period, gender and presence of wisdom teeth were not significantly effected TMJ disc in terms of DPI values in mouth opened or closed position (p> 0.05).
Conclusion: According to our study TMJ disc position was not effected significantly by SARME (p > 0.05).
