目的比较前方牵引矫治法(A组)与唇向扩弓活动矫治法(B组)均联合方丝弓在替牙期功能性安氏Ⅲ类错患者中的应用效果。方法将我院正畸门诊的替牙期的功能性安氏Ⅲ类错患者30例按治疗方法不同分为A、B两组,分别比较A组(n=13)和B组(n=17)的矫治结果、矫治周期、患者身体适应期、心理接受度、治疗成本、操作难易程度等。结果两组患者对最终矫治结果均表示较满意。但B法较A法矫治周期短,患者身体适应时间短,操作简单,耗时短,且维护简单,治疗成本相对低。结论唇向扩弓矫治法较前方牵引矫治法有更多的优点,更值得临床医生推广应用。
Objective To compare the effect of anterior traction reparation (group A) and lip-extension surgery (group B) combined with square archwire in patients with functional Class Ⅲ malocclusion at the occlusion period. Methods Thirty patients with functional Class Ⅲ malocclusion at orthodontic treatment in our hospital were divided into two groups according to the different treatment methods. Group A (n = 13) and group B (n = 17) results of orthodontic treatment, orthodontic cycle, patient’s physical adaptation, psychological acceptance, treatment cost, ease of operation and so on. Results Both groups were satisfied with the results of final treatment. However, the B method is shorter than the A method, and the patient has a short time to adapt to the body. The operation is simple, the time is short, and the maintenance is simple and the treatment cost is relatively low. Conclusion Laryngeal augmentation correction method has more advantages than the former traction correction method, more worthy of clinicians to promote the application.
