摘　　要：目的:研究反[牙合]伴单侧颞下颌关节紊乱病患者颞下颌关节的CBCT影像学特点。方法:收集52例确诊为单侧颞下颌关节结构紊乱伴反[牙合]患者临床资料,并进行CBCT影像学检查。利用Mimics 22.0软件重建髁突-关节窝,测量患者双侧关节间隙、关节窝深度、关节结节斜度及骨密度。运用SPSS22.0软件对数据做分析。结果:单侧DD伴反[牙合]患者健患侧对比,患侧前间隙增大。按口腔中反[牙合]牙位置(即前、后牙是否均有反[牙合])为依据分组中,前后牙均反[牙合]组与非前后牙均反[牙合]组对比,患侧前间隙与患侧上间隙具有统计学意义(P<0.05),其余检测指标均无统计学意义。结论:反[牙合]会造成髁突-关节窝影像学改变,造成患侧前间隙增宽,CBCT能较好地显示颞下颌关节骨性结构及关节间隙的改变。Objective:To study the CBCT imaging features of temporomandibular joint in patients with unilateral crossbite and temporomandibular joint disc displacement(DD).Methods:A total of 52 patients with unilateral crossbite and DD were enrolled in the clinical data and CBCT imagings were performed.The condyle-joint socket was reconstructed using Mimics 22.0 software,and the joint depth,joint nodule slope,joint space were measured.Data were analyzed using SPSS22.0 software.Results:The anterior space was increased in the patients with unilateral crossbite and DD.According to the position of the crossbite in the oral cavity(whether the anterior and posterior teeth were crossbite),the anterior and upper spaces in patients whose anterior and posterior teeth were non-crossbite were bigger than those had crossbite(P<0.05).Conclusion:Crossbite can cause imaging changes in the condyle-joint socket,resulting in widening of the anterior space of the affected side.CBCT can better show the changes of the skeletal structure and joint space of the temporomandibular joint.
