摘要/Abstract

摘要： 目的利用Mimics软件研究不同性别、正常健康人群与颞下颌关节紊乱病(temporomandibular disorders,TMD)患者髁突形态学及位置差异。方法从台州市中心医院口腔科就诊患者中选取符合纳入标准的研究对象40例,符合TMD诊断患者20例为研究组,无关节疾患的安氏Ⅰ类错牙合正常健康人群20例为对照组,行锥形束CT扫描,利用Mimics19.0三维重建,测量髁突体积、表面积、形态学指数(morphological index,MI),进行统计学分析。结果 TMD患者髁突体积、表面积、MI值均小于正常健康人群(P<0.05),男性髁突体积、表面积、MI值均大于女性(P<0.05),左右侧髁突体积、表面积、MI值差异无统计学意义(P>0.05)。结论 TMD患者相比正常健康人群髁突体积、表面积更小,Mimics软件可以有效地测量髁突体积和表面积,并为确立正常人群和TMD患者髁突体积和表面积参考值提供助力。

Abstract: Objective To study the morphological differences of condyles in different genders, positions, normal healthy people and temporomandibular disorders(TMD)patients by using Mimics software. Methods Forty subjects were enrolled in our study from the Department of Stomatology, Taizhou Central Hospital(Taizhou University Hospital). Twenty patients with TMD and 20 volunteers without temporomandibular joint(TMJ)disorders were included. All subjects received CBCT examination of the TMJ. Three-dimensional reconstruction of the condyle was conducted by Mimics 19.0 software and condylar volume, surface area and morphological index(MI) were measured and statistically analyzed. Results The condylar volume, surface area and MI of TMD patients were lower than those of normal population(P<0.05).The condylar volume, surface area and MI of males were higher than those of females(P<0.05), and there were no significant differences between left and right sides in the condylar volume, surface area and MI(P>0.05). Conclusion Patients with TMD have smaller condylar volume and surface area than normal population. Mimics can effectively measure condylar volume and surface area, and provide assistance for establishing reference values of condylar volume and surface area in normal population and patients with TMD.
