Abstract:

Objective

Study the radiological change of temporomandibular joint (TMJ) in the idiopathic condylar resorption(ICR)with cone beam computed tomography(CBCT)data.

Methods

Thirtynine patients with idiopathic condylar resorption and 28 volunteers without TMJ disorders were underwent CBCT examinations. Then the parameters of condyle-fossa relationship were assessed and statistically analyzed.

Results

Significantly statistical difference between the ICR group and normal group were detected in condylar medial-lateral distance, anteroposterior distance, articular eminence inclination,and joint space.

Conclusions

Shortened condyle, resorption of former cant, reduced articular eminence inclination, and an upward-moved and anteromedially-rotated condyle are good indicators for assessing ICR development and its treatment effect and prognosis.

Key words: Idiopathic condylar resorption, Temporomandibular joint, Cone beam computed tomography
