【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(P0.05);颧弓部分h2的宽度大于h3(P=0.048),d3的宽度大于d4(P0.01)。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 TMJ of temporomandibular joint (TMJ) with computed tomography (CT) reconstruction in Chinese. To elucidate the safe fixation area of TMJ prosthesis in Chinese. Methods: the width of zygomatic arch in bilateral TMJ prosthesis was measured by CT scanning and 3D reconstruction of 100 adults. The thickness and angle of H1H2H2OH3H3H3H4 and D2D2D3D3D4 ababa bccncncdcdnad, 伪 and 尾; Width and height of the articular fossa part BD and h; The width, thickness and angle of the mandibular branch: h _ (5) h _ (6) / h _ (7) ~ (1) ~ (1) ~ (1) ~ (1) ~ (l3) ~ (l3) ~ (1) ~ (l4) ~ (l5) / m _ (1) ~ (?). M5 and 纬. All the indexes were divided into two groups according to the direction. The difference of the two groups was compared by SPSS 19.0 software. Results: the zygomatic arch of TMJ was measured. The measurement index of prosthetic fixation region of articular fossa and mandibular branch was H1OH2H2H3OH4 (H1H2H3H4), H1H2H3H4, H1H2H4, H1H2H3H4, H1H2, H2H3, D4D4, BCD5, 伪, 尾, BDH5. The data of H7, L1, l2, l3, l4, l5, m1, m2m3, m3, m4, m5 and 纬. There was no significant difference between the two groups (P 0.05). The width of H2 in zygomatic arch was larger than that in H3 Pu 0.048). The width of d3 is larger than that of d4 P0.010.Conclusion: the data of Chinese TMJ prosthesis safety fixation area are obtained by using 3D CT images.

【正文快照】： 颞下颌关节(temporomandibular joint,TMJ)由颞骨鳞部的关节窝、下颌骨的髁突和二者之间的关节盘及周围韧带组成。多种TMJ疾病会造成其结构破坏进而影响其重要生理功能和患者的生活质量,需进行手术修复和功能重建。安放TMJ假体是被广大患者接受的治疗上述疾病的重要手段之一[1
