目的对微种植钉支抗与其它支抗技术临床应用效果进行分析比较。方法随机选择我院双颌前突较为严重患者55名,分成A、B两组,A组32名患者为治疗组,给予微种植钉支抗技术医治;B组23名患者为对照组,给予南西氏弓及口外弓联合支抗技术医治。结果经治疗,A组患者疗程相对于对照组较短,上下唇内收值明显大于B组,U1-SN角度缩小值小于B组,有效率高于B组,患者满意度高于B组患者。结论微种植钉支抗相对于其它支抗技术,效果较好。
Objective To compare and analyze the clinical effect of micro-implant nail support and other support techniques. Methods A total of 55 patients with severe bimaxillary protrusion in our hospital were randomly divided into two groups: A and B, and 32 patients in A group were treated with micro-implant nail technique. Twenty-three patients in B group were given control South West s bow and mouth combined with anti-tumor technique. Results After treatment, the duration of treatment in group A was shorter than that in control group. The values in upper and lower lips were significantly greater than those in group B, and the reduction in angle of U1-SN was smaller than that in group B, and the efficiency was higher in group A than in group B . Conclusion Micro-implant nail support is better than other support techniques.
