摘要/Abstract

摘要： 目的:研究骨性Ⅰ类非高角错牙合颏部软组织形态与牙颌面结构的相关性。方法:选择40例骨组织颏形态正常的患者为研究对象,排除下颌后缩与高角的干扰(0<ANB<5°,SN-MP<40°),根据软组织颏形态不同将研究对象分为颏形态正常组和颏形态异常组,分别测量矢状向、垂直向、牙性等参数,用SPSS 26.0软件包进行统计分析。结果:反映矢状向和下颌骨颏形态的参数没有显著性差异,颏形态异常组的后前面高比S-Go∶N-Me小于正常组(P<0.05),腭平面、牙合平面与下颌平面角的交角(PP-MP,OP-MP)显著大于正常组(P<0.05) 且与软组织颏形态(d∶B’Mess)呈负相关(P<0.05),腭平面与前颅底平面的交角(SN-PP)小于正常组(P<0.05),下切牙与眶耳平面交角(L1-FH)小于正常组(P<0.05)。结论:腭平面的倾斜度与软组织颏形态显著相关,当腭平面呈现出逆时针方向的趋势时,颏部形态差,上下颌骨离散程度大。

Abstract: Objective: To investigate the correlation between soft tissue chin morphology and dento-maxillofacial structure in skeletal class Ⅰ malocclusion without high angle. Methods: Forty patients with normal skeletal chin morphology were selected as the research objects, and the interferences of mandibular retrognathia and high angle were excluded (0<ANB<5°, SN-MP<40°). They were divided into normal chin morphology group and abnormal chin morphology group according to soft tissue chin morphology. Parameters related to sagittal and vertical pattern and dentition were measured respectively. Results: There was no significant difference in the parameters reflecting the sagittal pattern and mandibular morphology. Compared with the normal chin morphology group, the abnormal group exhibited decreased S-Go∶N-Me ratio (P<0.05), increased PP-MP and OP-MP (P<0.05) which negatively correlated with soft tissue chin morphology (d∶B’Mess) (P<0.05), and decreased SN-PP and L1-FH (P<0.05). Conclusion: The inclination of palatal plane is significantly related to soft tissue chin morphology. When the palatal plane shows a counterclockwise direction, the chin morphology worsens with increased dispersion of the maxilla and mandible.
