摘要: 目的:通过CT及MR数据结合三维重建软件建立关节盘前移位颞下颌关节的数字化仿真模型。方法:根据马绪臣颞下颌关节病分类标准,选取成年颞下颌关节紊乱病志愿者1名,X线片及CT检查排除颌骨疾患及颌面部肿瘤,MR斜矢状位扫描明确右侧颞下颌关节盘分界角向前为12.21°,盘前分界超过关节结节顶点。通过Simpleware及Ansys等三维重建软件处理其右侧颞下颌关节的CT薄层扫描数据及3D-MR扫描数据,建立关节盘前移位颞下颌关节的数字化仿真模型。结果:建立了包括骨皮质、骨松质、软骨和关节盘在内的关节盘前移位颞下颌关节数字化仿真模型,客观反应了关节盘前移位时颞下颌关节的外形及解剖特点。结论:成功建立了关节盘前移位颞下颌关节的数字化仿真模型,为关节盘前移位的研究奠定了基础。

Abstract: Objective:  This study purposed to describe a TMJ  digital simulation model with anterior disc displacement fabricated by three dimensional reconstruction technology. Methods: One volunteer with TMJ disorder was selected. X-ray and CT examination was performed to exclude related mandible diseases and tumors. The anterior disc displacement was diagnosed by oblique sagittal MR scanning which showed that the Drace was 12.21° and the plate boundary crossed the joint nodules. The digital simulation model  was established by Simpleware and Ansys software on the basis of the imaging data obtained from the head spiral CT and 3D-MR scanning. Results: Digital simulation model of temporomandibular joint with anterior disc displacement which accurately showed their anatomic structures was successfully fabricated. Conclusions: The establishment of the digital simulation model of temporomandibular joint with anterior disc displacement is high precise and verisimilar, which can be widely applied in the biomechanical research.

Key words: anterior disc displacement, temporomandibular joint, digital simulation model
