微种植体支抗在双颌前突正畸治疗中的应用意义

Micro implant anchorage in orthodontic treatment of bimaxillary protrusion in the application

目的:微种植体与非微种植体支抗在双颌前突正畸治疗中的疗效及临床意义。方法:将100例双颌前突患者随机分为对照组50例(非微种植体支抗),观察组50例(微种植体支抗),对照两组患者治疗后上、下颌切牙切缘内收、磨牙前移水平及疗效比较。结果:两组患者治疗后上、下颌切牙切缘内收、磨牙前移水平比较(t=4.67、4.66、4.68,P<0.05,具有显著性差异),两组治疗后疗效比较(χ2=4.66、4.78.4.55,P<0.05,具有显著性差异)。结论:微种植体支抗在双颌前突正畸治疗中具有效果确切疗效好的特点值得临床推广。

Objective Micro Implant with a micro implant anchorage in orthodontic treatment of bimaxillary protrusion in the curative effect and the clinical significance. Methods 100 patients with bimaxillary protrusion were randomly divided into 50 cases in the control group （ no Micro Implant Anchorage ）, 50 cases in observation group （ Micro Implant Anchorage ）, control group two patients after treatment, mandibular incisor margin adduction, molar advancement level and effect. Results of two groups of patients after treatment, mandibular incisor margin adduction, molar advancement level comparison （ t=4.67, 4.66, 4.68, P〈0.05, with significant difference ）, efficacy of the two groups after treatment （χ2=4.66, 4.78.4.55, P〈0.05 comparison, significant difference ）. Conclusion micro implant anchorage in orthodontic treatment of bimaxillary protrusion with the exact effect the characteristics of a good curative effect in clinic.
