【摘要】：目的:分析下切牙倾斜度在不同垂直骨面型侧貌美观患者中的差异,为临床矫治设计提供参考。方法:收集正畸固定矫治结束的侧貌美观女性患者137例,按前颅底平面与下颌平面交角(∠SN-MP)将患者分为3组:低角组(31例)、均角组(89例)及高角组(17例),测量下中切牙与下颌平面交角(∠L1/MP)、下中切牙与上齿槽座点-颏前点连线交角(∠L1/A-Pog),协方差分析不同组间的差异。结果:∠L1/MP(°)在高角组中最小,低角组中最大,均角组居中,3组间差异有统计学意义(F=17.38,P0.001),∠L1/A-Pog(°)在3组间差异无统计学意义(F=2.63,P0.05)。结论:高角型侧貌美观患者下切牙舌向倾斜代偿,低角型唇向倾斜代偿,在制订矫治计划时应结合患者垂直骨面型,综合考虑患者下切牙的倾斜度。
[Abstract]:Objective: to analyze the difference of lower incisor inclination in different vertical bone facial appearance patients, and to provide reference for clinical orthodontic design. Methods: 137 female patients with beautiful side appearance after orthodontic fixation were collected. The patients were divided into three groups according to the angle of anterior skull base plane to mandibular plane ( SN-MPP): low angle group (31 cases), average angle group (89 cases) and high angle group (17 cases). The angle of inferior central incisor and mandibular plane was measured. Angle of intersection of anterior mental line (1 / A-Pogg), covariance analysis of differences between different groups. Results: the average angle group was the lowest in the high angle group and the largest in the low angle group. There was significant difference in the mean angle group between the middle group and the middle angle group (P 0.001), and there was no significant difference between the three groups in the angle L 1 / A Pogo (掳). There was no significant difference between the three groups in the mean angle group (F = 2.63P 0.05). Conclusion: the lower incisor obliquity compensation and low angle labial obliquity compensation in the patients with high angle lateral beauty should be combined with the vertical bone facial type and the inclination of the lower incisor should be taken into account in the preparation of the orthodontic plan.
