摘要
目的:分析安氏Ⅱ类Ⅰ分类错女性唇部软组织厚度与唇部回收的关系。方法:选取某城市中270例成年人作为研究对象,并按照性别分为两组,两组均为135例。随后通过定位测量头颅侧位片的方式建立本研究的唇部厚度标准,分析不同性别上唇软组织厚度的差异和男女不同唇型的方差分析差异,同时根据该标准对女性唇部软组织厚度与唇部回收的关系进行分析。分析项目包括女性不同唇型软组织厚度切牙上唇回收比差异、影响女性唇部回收的因素及相关性。结果:通过对上述各项指标进行观察分析发现,(1)男性群体的上唇厚度显著高于女性群体(P<0.05);(2)两组的唇型并对其进行方差分析发现组间结果差异较为显著(P<0.05);(3)利用LSD-t对唇型进行组内比较发现薄唇型与厚唇型、均衡型与厚唇型、薄唇型与均衡型三项比较结果的差异均较为显著(P<0.05);(4)薄唇组的唇部回收量最大,厚唇组的唇部回收量则最小;(5)不同性别上唇软组织厚度、不同唇型软组织厚度以及正畸治疗后不同唇型软组织厚度均能影响唇部回收量,并且切牙唇部回收程度与上唇软组织的厚度之间的关系为负相关。结论:不同性别的错人群实施正畸治疗调整上唇软组织的厚度对唇部回收程度有影响,需采取具有针对性的措施进行正畸治疗。
Objective:To analyze the relationship between lips soft tissue thickness and lips retrusion in ClassⅡdivision I malocclusion.Methods:270 adults in a certain city were selected as subjects and divided into two groups according to gender,135 cases in each group.Subsequently,the lips thickness standard in this study was established by measuring the cranial lateral radiographs.The difference in upper lips soft tissue thickness of different genders and the analysis of variance of different lip types between male and female were analyzed,as well as the relationship of recycling.The analysis included the differences in the retrusion ratio of the upper lip of the incisors and the factors affecting the retrusion of the female lips.Results:Through observation and analysis of the above indicators,it was found that(1)the upper lip thickness of the male group was significantly higher than that of the female group,P<0.05.(2)The lip shapes of the two groups are different and analysis of variance showed that the difference of the two groups were significant.P<0.05.(3)Using LSD-t test to compare the lip shapes within the same group,it was found that the difference between the three comparison results of the thin lip type and the thick lip type,the balanced type and the thick lip type,the thin lip type and the balanced type are more significant.P<0.05.(4)The thin lip group had the largest amount of lip retrusion,and the thick lip group has the smallest lip recovery.(5)The thickness of the upper lip tissue of different genders,the thickness of different lip soft tissues and the thickness of different lip soft tissues after orthodontic treatment can affect the amount of lip retrusion,and the difference of lip recovery of the incisors and the thickness of the upper lip soft tissue.The relationship between the degree of incisor lip recovery and the thickness of upper lip soft tissue is negatively correlated.Conclusion:Adjusting the thickness of the soft tissue of the upper lips by orthodontic treatment of people with malocclusion can affect the degree of lips recovery and thus affect the profile.Thus targeted measures should be taken in the process of orthodontics treatment.
