摘　　要：目的:通过对比不同的覆盖覆条件下下唇形态的差异,为临床诊断和治疗提供参考依据。方法:选取前牙正常覆盖覆为对照组25例,深覆盖正常覆,正常覆盖深覆,深覆盖深覆3组为实验组,各25例。应用invivo 5.4三维测量软件对5项下唇软组织测量项目进行测量分析。结果:与对照组相比,3组实验组中除深覆盖正常覆组的Stmi-Me'外其测量项目均有统计学差异;3组实验组两两比较,深覆盖正常覆组与正常覆盖深覆组的Li-L1、B'Li-FH及LiB'Pg'有统计学差异,深覆盖正常覆组与深覆盖深覆组的Li-L1、B'Li-FH、Stmi-Me'及LiB'Pg'有统计学差异。结论:覆盖覆均对下唇形态有影响,覆对下唇的影响相对更大。Objective：To provide the basis for clinical diagnosis and treatment by observing the morphology of lower lip soft tissue at different conditions of overjet and overbite.Methods：The experiment was divided into four groups：control group,overjet and overbite（n=25）;experimental group,deep overjet normal overbite（n=25）,normal overjet deep overbite（n=25）,and deep overjet deep overbite（n=25）.Five measurements and analyses of lower lip soft tissue were performed with Invivo5.4software.Results：Compared with control group,significant difference was found among the three experimental groups except Stmi-Me’of deep overjet normal overbite group.Among multiple comparisons between three experimental groups,there were significant differences between deep overjet normal overbite group and normal overjet deep overbite group on Li-L1,B’Li-FH,and LiB’Pg’;between deep overjet normal overbite group and deep overjet deep overbite group on Li-L1,B’Li-FH,Stmi-Me’,and LiB’Pg’.Conclusion：Both overjet and overbite have an influence on morphology of lower lip soft tissue,and overbite influences more.
