目的:探讨二次正畸治疗错畸形的疗效。方法:选择进行诊治的错畸形患者60例,都采用二次正畸治疗。结果:所有患者完成手术,牙齿排列整齐,咬合功能良好。术后患者的SNA与ANB值与术前对比差异有统计学意义(P<0.05),而SNB和U1-SNP值在手术前后对比差异无统计学意义(P>0.05)。结论:二次正畸治疗错畸形能取得很好的预后效果,值得推广应用。
Objective: To investigate the effect of secondary orthodontic treatment of malocclusion. Methods: Sixty patients with malocclusion deformities who were selected for diagnosis and treatment were treated with secondary orthodontics. Results: All patients completed the operation, the teeth arranged neatly, bite function well. There were significant differences in SNA and ANB between preoperative and postoperative patients (P <0.05), but there was no significant difference in SNB and U1-SNP before and after operation (P> 0.05). Conclusion: Secondary orthodontic treatment of malocclusion deformity can achieve good prognosis, it is worth popularizing and applying.
