目的:对应用矫正器对骨性Ⅲ类错牙合患者进行治疗的临床效果进行研究分析。方法:抽取76例患有骨性Ⅲ类错牙合的患者病例,将其分为对照组和治疗组,平均每组38例。对照组患者采用活动矫治器方法牙合垫舌簧进行治疗;治疗组患者采用固定矫正器加活动矫治进行治疗。结果:治疗组患者骨性Ⅲ类错牙合症状治疗效果明显优于对照组;治疗前后上下唇和切牙位置的改善幅度明显大于对照组;不良反应发生率明显低于对照组。结论:应用固定矫正器与活动矫治器联合运用对骨性Ⅲ类错牙合患者进行治疗的临床效果非常明显。
Objective: To study the clinical effect of orthosis on the treatment of skeletal Class Ⅲ malocclusion. Methods: A total of 76 cases of patients with skeletal Class Ⅲ malocclusion were selected and divided into control group and treatment group with an average of 38 cases in each group. The patients in the control group were treated with the active appliance method of occlusal flap reed; the patients in the treatment group were treated with fixed appliance and active appliance. Results: The treatment effect of group Ⅲ malocclusion was significantly better than that of control group. The improvement of upper and lower lip and incisors position was significantly greater than that of control group before and after treatment. The incidence of adverse reactions was significantly lower than that of control group. Conclusion: The clinical effect of using fixed orthotics and active appliances in the treatment of patients with skeletal Class Ⅲ malocclusion is very obvious.
