摘要
目的比较哈尔滨地区安氏Ⅰ、Ⅱ、Ⅲ类错畸形患者唇形态的差异,探讨头影线性测量与头影区域测量之间的关系。方法选取120例哈尔滨地区18~25岁女性错畸形患者为研究对象,根据治疗前头颅定位侧位片上∠ANB大小划分为Ⅰ、Ⅱ、Ⅲ类骨型,每类骨型各有40例患者,要求型与骨型一致。对其X线头颅定位侧位片上21项唇部软组织项目进行测量,并采用SPSS13.0统计软件对测量结果进行方差分析和两两比较。结果安氏Ⅰ、Ⅱ、Ⅲ类错畸形患者唇形态的差异有统计学意义(P<0.05),以安氏Ⅱ、Ⅰ、Ⅲ类为序,上唇-审美平面距、上唇突度、上下唇突度差、软组织ANB角、下唇中部面积呈递减趋势,下唇倾角、下唇基角和上唇上部面积呈递增趋势。以安氏Ⅱ、Ⅲ、Ⅰ类为序,颏唇沟角和Z角呈递增趋势,下唇-审美平面距呈递减趋势。上下唇长度的差异无统计学意义(P>0.05)。结论安氏Ⅰ、Ⅱ、Ⅲ类错畸形的唇形态有一定差异,按照Ⅱ、Ⅰ、Ⅲ类的顺序,唇部软组织覆盖有倾向于减小上唇突度和增加下唇突度的趋势。头影区域测量能够准确反映唇部组织的分布情况。
Objective To get reference for the diagnosis design and the clinical diagnosis,the difference is compared among lip profile on malocclusion of ClassⅠ,Ⅱ and Ⅲ from patients in Harbin,and the relationship is established between the linear cephalometric measurements and the regional cephalometric measurements.Methods 120 female patients,18-25 years old,were selected.According to the value of ∠ANB which was measured on the pre-treatment cephalographs,they were divided into three groups—Class Ⅰ,Ⅱ and Ⅲ.Each group had 40 patients.Each patient had the same type of skeletal pattern and occlusion pattern,and then 21 lip soft tissues were measured.Finally,the results of measurements were statistically analyzed with ANOVA and were compared between members in each group via SPSS 13.0 software.Results The differences among patients with lip profile on malocclusion had statistic significances(P0.05).In order of Class Ⅱ,Ⅰ and Ⅲ,the UL-E,ULP,ULP-LLP,Sn-Ns-B' and S4 were progressively decreased and the B'-LL-FH,S-Ns-B' and S1 were increased.In order of Class Ⅱ,Ⅲ and Ⅰ,the LL-B'-Pos and Z-angle were raised and LL-E was reduced.The length of the upper lip and the lower lip had no statistic significance(P〈0.05).Conclusion There is difference among the ClassⅠ,Ⅱ and Ⅲ.The lip covering area is inclined to decrease the changes of the upper lip and increase the changes of the lower lip progressively with the variation of skeletal patterns in order of Class Ⅱ,Ⅰ,and Ⅲ.Moreover,the condition of lip tissues can be accurately presented by the regional cephalometric measurements.
