摘要: 目的:研究特发性髁突吸收(ICR)患者下颌骨锥体束CT(CBCT)的影像学特点。方法:选取ICR患者和正常志愿者各41例,应用Invivo5软件测量所有受试者下颌骨CBCT数据资料,并进行统计学分析。结果:ICR组与正常组间SNB、NP-FH、S-Go、S-Go/N-Me、Co-Go、H、ACo-PCo、PCo-Co、前斜角、S-Ar-Go、Co-Go-Me的差异有统计学意义(P<0.05),而N-Me、Go-Me、S-Co、ACo-Co、后斜角无统计学意义(P>0.05)。结论:ICR仅发生在髁突的顶端和前斜面,以髁突高度降低为主。ICR患者的下颌后缩由下颌骨后下旋转引起,而非髁突后移所致。

Abstract: Objective: To analyze the radiographic features of mandibular cone beam computed tomography (CBCT) films in patients with idiopathic condylar resorption (ICR). Methods: Forty-one ICR patients on their first visit to the Department of Orthodontics were selected as the experiment group, and 41 healthy volunteers were served as the control group. Mandibular indicators on CBCT were collected by Invivo5 software and the statistical differences were analyzed by SPSS 17.0. Results: Indicators that showed significant differences between the experimental group and control group included SNB, NP-FH, S-Go, Co-Go, S-Go/N-Me, H, ACo-PCo, PCo-Co , angle of anterior slope, S-Ar-Go and Co-Go-Me (P<0.05), while those showed no significant differences between two groups included N-Me, Go-Me, S-PCo, ACo-Co and angle of posterior slope(P>0.05). Conclusion: Bone resorption in ICR mainly occurred in the top and anterior slope of the condyle, resulted in reduction of condylar height, which was a main feature of ICR. The mandibular retraction in ICR patients was caused by the rotating of the mandible rather than the receding of the condyle.
