摘要
目的:探讨恒牙初期安氏Ⅲ类错软组织侧貌特征,分析硬组织改变对软组织侧貌的影响。方法:选择恒牙初期正常、安氏III类错青少年各50名,确定22项常用的软组织侧貌测量指标和9项硬组织测量指标进行X线头影测量。结果:除9项软组织测量值和1项硬组织测量值外,其余软硬组织测量值均有显著性差异(P<0.01)。多因素判别分析筛选出LsNsLi、CmSnLs、NsLi-FH、Ls-E、Li-E5项主要软组织指标。软硬组织有显著相关性(P<0.05)。结论:III类错青少年软组织侧貌明显异常,最敏感的、最能体现III类错软组织侧貌异常的有5项软组织指标。正畸临床中可有针对性的纠正硬组织异常来改善软组织不调。
Objectives：To study the soft tissue profile characteristic in the early permanent dentition with Class Ⅲ malocclusion, and then to analyze the relationship between hard and soft tissue. Methods： 50 normal occlusion and 50 Class Ⅲ malocclusion children were examined cephalometrially with the lip at rest. Results：Compared with the normal occlusion group, All measurement except 9 soft tissue variables and 1 hard tissue variables was statistically significant with t-test in the Class Ⅲ malocclusion group （P 〈 0.05 ）. Five indexes were selected through discriminant analysis. Pearson correlation analyses showed there was correlation between the hard tissue variables and the facial balance indexes. Conclusion：LsNsLi,CmSnLs,NsLi-FH,Ls-E and Li-E were selected as five indexes which may represent the abnormality of facial profile of Class III malocclusion. The soft tissue profile will be harmonious by the treatment of inharmonious hard tissue.
