摘要/Abstract

摘要： 目的　探讨骨性Ⅲ类错患者正畸正颌联合治疗前后面部软组织变化的特征。方法　选择在江苏省口腔医院正畸科就诊的14例骨性III类错畸形的患者为研究对象，分别于正畸正颌联合治疗前后拍摄3dMD，利用3dMD vultus软件对颌面部软组织进行重建，然后选取面部软组织有代表性的17个三维标志点并测量线距和角度，比较骨性III类错患者正畸正颌联合治疗前后的差异。结果　面凸角、鼻唇角、颏唇角、上唇长度、鼻翼宽度及鼻基底宽度有统计学差异， P<0.05。结论　1.3dMD提供了三维测量软组织的一种方法。2.骨性III类错患者正畸正颌联合治疗前后面型改善。

Abstract: 　Objective　To investigate the changes of facial soft tissue before and after orthodontic and orthognathic treatment in patients with skeletal Class Ⅲ malocclusion。Methods　14 patients with skeletal Class Ⅲ malocclusion are chosen from the Orthodontic Department of Jiangsu provincial stomatological hospital. The patients are required to take 3dMD photos before and after treatments. We use 3dMD vultus to rebuild the patients ’soft tissues. In order to compare the soft tissue changes, 17 points are selected and are used for length and angle measurements. Results：A significant difference was found in the angle of N‘-Sn-Pog‘，the nasolabial angle ，the mentolabial angle、the length of upper lip and the width of alar and alar base。Conclusions　1.3dMD provides a method for three-dimensional measurement of soft tissue. 2. The profile of patients with skeletal class III malocclusion were improved before and after orthodontic and orthognathic treatment。

Key words: skeletal Class Ⅲ malocclusion, orthodonticandorthognathictreatment, three-dimensional photogrammetry, facial soft tissue change
