目的 比较哈尔滨地区安氏Ⅰ、Ⅱ、Ⅲ类错(牙合)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(牙合)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(牙合)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SPSS 13.0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(牙合)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,上唇一审美平面距、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,下唇一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(牙合)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.
目的 比較哈爾濱地區安氏Ⅰ、Ⅱ、Ⅲ類錯(牙閤)畸形患者脣形態的差異,探討頭影線性測量與頭影區域測量之間的關繫.方法 選取120例哈爾濱地區18～25歲女性錯(牙閤)畸形患者為研究對象,根據治療前頭顱定位側位片上∠ANB大小劃分為Ⅰ、Ⅱ、Ⅲ類骨型,每類骨型各有40例患者,要求(牙閤)型與骨型一緻.對其X線頭顱定位側位片上21項脣部軟組織項目進行測量,併採用SPSS 13.0統計軟件對測量結果進行方差分析和兩兩比較.結果 安氏Ⅰ、Ⅱ、Ⅲ類錯(牙閤)畸形患者脣形態的差異有統計學意義P<0.05),以安氏Ⅱ、Ⅰ、Ⅲ類為序,上脣一審美平麵距、上脣突度、上下脣突度差、軟組織ANB角、下脣中部麵積呈遞減趨勢,下脣傾角、下脣基角和上脣上部麵積呈遞增趨勢.以安氏Ⅱ、Ⅲ、Ⅰ類為序,頦脣溝角和Z角呈遞增趨勢,下脣一審美平麵距呈遞減趨勢.上下脣長度的差異無統計學意義(P>0.05).結論 安氏Ⅰ、Ⅱ、Ⅲ類錯(牙閤)畸形的脣形態有一定差異,按照Ⅱ、Ⅰ、Ⅲ類的順序,脣部軟組織覆蓋有傾嚮于減小上脣突度和增加下脣突度的趨勢.頭影區域測量能夠準確反映脣部組織的分佈情況.

Objective To get reference for the diagnosis design and the clinical diagnosis, the difference is compared among lip profile on malocclusion of Class Ⅰ, 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 (P<0.05). 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 SI were increased. In order of Class II, ID 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 Class Ⅰ, 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 accu rately presented by the regional cephalometric measurements.
