单侧后牙长期缺失后髁突形态的锥形束CT研究
目的采用锥形束CT（CBCT）研究单侧后牙长期游离缺失对双侧髁突形态的影响。方法收集30例单侧后牙长期游离缺失患者和30例正常对照者的CBCT图像,应用Mimics 15.0软件测量双侧髁突体积、面积、线距及骨密度,对测量结果进行统计学分析。结果缺牙侧的髁突体积、髁顶体积及其骨密度明显小于非缺牙侧（P〈0.05）;髁突横截平面的面积及其骨密度大于非缺牙侧（P〈0.05）。结论单侧后牙长期游离缺失后,双侧髁突均发生适应性改建,缺牙侧髁突小于非缺牙侧。...

Hangzhou Bofan Dental Hospital, Hangzhou 310007, China） cone beam computed tomography; posterior teeth loss; condyle 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 rec |
