文题释义:
颞下颌关节:颞下颌关节由下颌骨髁突、颞骨关节面、居于二者之间的关节盘、关节周围的关节囊和关节韧带(颞下颌韧带、蝶下颌韧带、茎突下颌韧带)所组成。是颌面部唯一的左右双侧联动关节,具有一定的稳定性和多方向的活动性。在肌肉作用下产生与咀嚼、吞咽、语言、及表情等有关的各种重要活动。
数字解剖:是通过计算机技术,将人体结构数字化,在电脑屏幕上出现看得见的、能够调控的虚拟人体形态,进一步测量比较分析的学科。
 
摘要
背景:
颞下颌关节结构功能复杂,国外假体不适合国人解剖学参数,因此临床急需相关参数以指导适合国人假体的设计。
目的:通过计算机三维数字化法对颞下颌关节应用解剖学参数进行测量,为人工颞下颌关节设计改进提供参考。
方法:选取正常颞下颌关节CT连续影像学扫描资料30例,层厚0.625 mm,采用Mimics10.01软件进行三维数字化重建并测量关节窝、髁突等8项相关解剖学参数。
结果与结论:下颌头、下颌颈和下颌窝内外径均大于前后径,下颌孔位于下颌支中后部,下颌头与冠突的距离大于下颌切迹的深度,全部指标左右侧别间差异无显著性意义。结果说明颞下颌关节骨性结构解剖学参数具有一定规律,所以实验结果可为标准型颞下颌关节假体设计提供理论参数。

Abstract:

BACKGROUND: Guidances for design of Chinese people’s temporomandibular joint prosthesis are urgently needed because foreign prosthesis is unsuitable for Chinese people due to variant anatomy parameters.
OBJECTIVE: To provide a reference for improving the design of artificial temporomandibular joint through computer three-dimensional digital measures of the anatomy parameters of the temporomandibular joint.
METHODS: Continuous CT data with layer thick 0.625 mm of 30 normal temporomandibular joints were selected. Three-dimensional digital reconstruction and eight related anatomy parameter measurements of the articular fossa and condylar of the joints were performed using Mimics10.01 software.
RESULTS AND CONCLUSION: The internal and external diameter of the mandibular fossa, head of mandible and neck of mandible were greater than the anterior and posterior diameter. The mandibular foramen was located at middle-posterior of the ramus of the mandible. The distance between head of the mandible and coronoid process was longer than the depth of the mandibular notch. There were no significant differences between two sides regarding all above-mentioned parameters. There are certain regular patterns in anatomy parameters of the temporomandibular joint. The study results will provide a reference for improving the design of artificial temporomandibular joint.
