摘要: [摘要」 目的 评估片段隐形矫治器结合微种植体矫治前突患者时对上前牙垂直向和转矩方面的控制效果。 方法 选取12例双牙槽前突患者,通过测量治疗前后X线头颅定位侧位片上颌前牙矢状向与垂直向的变化值,以及模型上的转矩变化值,使用SPSS20. 0软件进行统计分析。 结果 治疗后上切牙切缘至腭平面距离U1E-PP增加0.78mm,上切牙根尖点至腭平面距离U1AP-PP减小0.29mm,上切牙阻抗中心至腭平面距离U1CR-PP的变化无统计学差异(P > 0.05),上切牙阻抗中心的位置基本不变;治疗后的上前牙转矩值减少,尖牙出现直立趋势。 结论 片段隐形矫治技术治疗前突患者对其上前牙的垂直向和转矩控制较好,总体获到了良好的治疗效果,并且在治疗期间充分发挥了隐形、美观的矫治效果。

Abstract: Abstract: Objective To evaluate the clinical efficiency of segmental invisible technique with mini-implant for en-masse retraction of maxillary anterior teeth on the aspect of vertical and torque in the treatment of bimaxillary protrusion. Methods Twelve subjects with upper dental alveolar bone protrusion were selected for this study. Arch-dimension variables were evaluated by cephalometric and dental models before and after orthodontic retraction. All data were analyzed by SPSS20. 0 software. Results For vertical control,U1E-PP was decreased by 0.78mm, U1AP-PP was decreased by 0.29mm,while U1CR-PP was showed no significant difference(P > 0.05). For sagittal control,all the anterior teeth were showed a decreased torque with canine displayed uprighting. Conclusion Segmental invisible technique with mini-implant is efficient in the vertical and torque control of anterior teeth in the treatment of bimaxillary protrusion,and provide an invisible effect meanwhile.
