Treatment of malocclusion of lateral incisor abnormality by orthodontic-prosthesis combined therapy

目的探讨正畸与修复联合治疗伴侧切牙异常的错畸形患者的临床效果。方法选择正畸门诊伴有侧切牙异常的错畸形患者49例,先期采用固定正畸技术,排齐整平牙弓,矫治异常的覆覆盖及偏斜的中线,对应好磨牙尖窝关系,合理集中或开辟间隙,后期进行固定冠桥修复或牙体美学修复。结果经过12～24个月先期正畸矫治和最后的修复治疗,49例患者牙齿排列整齐,中线对齐,无间隙,磨牙关系及覆牙合盖关系正常。结论对于伴有侧切牙异常的错畸形病例,应根据患者的年龄、面型、侧切牙缺失的数目、畸形牙大小、牙弓拥挤度、错类型及自身美观要求等综合考虑,具体分析,设计不同的治疗方案,采用正畸与修复联合治疗可以达到良好的临床效果。
