目的:分析种植体支抗辅助安氏Ⅰ类双牙弓前突矫治的疗效。方法:选取2011年6月至2013年12月收治的安氏Ⅰ类双牙弓前突患者37例,均使用唇侧矫治器配合微螺钉种植体支抗矫治,观察微螺钉种植体的稳定性,并对患者治疗前后的头颅侧位片进行头影测量,评价治疗效果,采用自制的调查表调查患者的满意度。结果:微螺钉种植体的成功率为95.9%。与矫治前比较,矫治后上颌前牙明显内收,上中切牙切端平均远中移动(5.8±1.3)mm,唇部与审美平面之间的距离显著减小,差异有统计学意义(P<0.05)。与矫治前比较,矫治后的上颌第一磨牙近中移动较少[(0.4±0.1)mm],差异无统计学意义(P>0.05)。37例患者完成矫治,满意33例,基本满意4例,满意率100%。结论:唇侧矫治器联合微螺钉种植体支抗治疗安氏Ⅰ类双牙弓前突患者,能够有效控制磨牙支抗,在内收上颌前牙的同时能有效控制转矩,治疗效果满意,患者满意度高。
OBJECTIVE: To analyze the effect of implant anchorage-assisted angioplasty on the treatment of Class Ⅰ bidentata protrusion. Methods: Thirty-seven patients with Class Ⅰ Bidentôs were admitted from June 2011 to December 2013. All the patients were treated with labial appliance and micro-screw implants, and the stability of micro-screw implants was observed , And before and after treatment of patients with cephalometric films cephalometric measurements to evaluate the therapeutic effect of using self-made questionnaire survey of patient satisfaction. Results: The success rate of micro-screw implants was 95.9%. Compared with those before treatment, the maxillary anterior teeth were obviously adducted, the incisors of the upper incisors moved on average (5.8 ± 1.3) mm, and the distance between the lip and the aesthetic plane was significantly reduced (P < 0.05). Compared with the pre-treatment, the maxillary first molar moved less ([(0.4 ± 0.1) mm], the difference was not statistically significant (P> 0.05). Thirty-seven patients completed correction, satisfied with 33 cases, basically satisfied with 4 cases, the satisfaction rate was 100%. Conclusion: The combination of labial appliance and micro-screw implants in the treatment of Class Ⅰ bidentata patients can effectively control the molar support and effectively control the torque while adducing the maxillary anterior teeth. The treatment effect is satisfactory, Patient satisfaction is high.
