Abstract:

Objective This study aimed at using cone beam computed tomography (CBCT) to study the influence of prolonged unilateral posterior teeth loss on bilateral condylar morphology. Methods  The CBCT images of 30 patients with prolonged unilateral posterior teeth loss and 30 healthy people as controls were corrected. Mimics 15.0 software was used to measure volume, area, distance, and bone density of condyle. The results were statistically analyzed. Results The volume and bone density of condylar head and the entire condyle on missing teeth side were less than the contralateral side (P<0.05). The area and bone density of condylar transverse plane were greater than the contralateral side (P<0.05). Conclusion  After prolonged unilateral posterior teeth loss, adaptive reconstruction occurs in the bilateral condyles, and condyle of missing teeth side is smaller than the contralateral side.
