摘要
目的:探讨上颌侧切牙先天缺失的治疗.方法:采用Broussard双力矫治技术,分别选择正畸关闭间隙及正畸集中间隙后义齿修复缺牙两种方法,对8例上颌侧切牙先天缺失患者进行治疗.结果:患者主要错牙合畸形得以纠正,对美观、功能改善满意,尖牙改形随访无异常.结论:(1)间隙集中法适合青少年安氏Ⅰ类、安氏Ⅲ类错牙合及所有成年患者;(2)关闭间隙法适合青少年安氏Ⅱ类错牙合伴上颌前突病例.尖牙改形替代侧切牙是安全可行的.
Object： To investigate the treatment of patients with congenital absence of upper lateral incisors. Methods： 8 patients with congenital absence of upper lateral incisors were selectively therapied by orthodontically redistributing the space prior to prosthodontics and by simply orthodontically closing the space. The orthodontical appliance used in all patients was Broussard two - forced technique system. Result ： All patients were delighted with the improvement both of aesthetics and function. No pathological changes were found in the reshaped canines in a review half a year later. Conclusion： （1） Space redistributing is preferable to young patients with class Ⅰ or class Ⅲ malocclusion and all adult patients. （2） Space closing is preferable to young patients with class Ⅱ malocclusion associated with proclined upper central incisors. The procedure of re.shaping eanine.s to resemble the missing lateral incisors is safe clinically.
