摘要: 目的:采用计算机断层扫描(CT)重建技术测量国人颞下颌关节(TMJ),阐明国人TMJ假体的安全固定区域。方法:对100例成年人头部进行CT扫描和三维重建,测量双侧TMJ假体固定区域中颧弓部分的宽度、厚度和角度h1、h2、h3、h4、d1、d2、d3、d4、ab、bc、cd、ad、α和β;关节窝部分的宽度和高度BD和h;下颌支部分的宽度、厚度和角度S、h5、h6、h7、l1、l2、l3、l4、l5、m1、m2、m3、m4、m5和γ。所有测量指标依据方向分为左右侧2组,采用SPSS 19.0软件比较左右侧2组测量指标的差异。结果:测得TMJ颧弓、关节窝和下颌支假体固定区域部分的测量指标h1、h2、h3、h4、d1、d2、d3、d4、ab、bc、cd、ad、α、β、BD、h、S、h5、h6、h7、l1、l2、l3、l4、l5、m1、m2、m3、m4、m5和γ的数据,左右侧2组各指标测量值比较差异均无统计学意义(P > 0.05);颧弓部分h2的宽度大于h3(P=0.048),d3的宽度大于d4(P < 0.01)。结论:采用CT三维图像得到了国人TMJ假体安全固定区域的测量数据。

Abstract: Objective: To measure the morphologic data of Chinese temporomandibular joint (TMJ) with computed tomography (CT) reconstruction technology, and to clarify the safe area for the fixation of Chinese temporomandibular joint prosthesis. Methods: A total of 100 adult skulls were scanned by CT and reconstructed.The width,thickness and angle h1,h2,h3,h4,d1,d2,d3,d4,ab,bc,cd,ad,αandβof zygomatic arch,the width and height BD and h of articular fossa and the width,thickness and angle S,h5,h6,h7,l1,l2,l3,l4,l5,m1,m2,m3,m4,m5 and γ of mandible in the fixed area of the TMJ prosthesis were measured; all the measurement indexes were divided into left and right groups by direction, and SPSS 19.0 software was used for the comparion of the measurement between left and right groups. Results: There were no statistical differences in the measurement index values of h1,h2,h3,h4,d1,d2,d3,d4,ab,bc,cd,ad,α,β,BD,h,S,h5,h6,h7,l1,l2,l3,l4,l5,m1,m2,m3,m4,m5 and γ in zygomatic arch, articular fossa and mandible in the fixed area of the TMJ prosthesis between left and right groups (P>0.05); the width of h2 was longer than that of h3 in zygomatic arch (P=0.048); the thickness of d3 was thicker than that of d4 (P<0.01). Conclusion: The measurement data of TMJ fixed area is obtained with three-dimensional CT images.
