摘要： 目的:探讨微种植体支抗矫治高角开牙合病例的可行性。方法:9例高角开牙合拔牙矫治病例,在双侧上、下颌后部牙槽骨上植入微种植体使用轻力对磨牙进行持续压低,对矫治前后的X线头颅定位侧位片进行测量分析。结果:治疗后所有患者建立了正常的覆牙合覆盖关系,上下磨牙被有效压低,下颌骨发生了逆时钟旋转,矫治前后SNB、ANB、MP-FH、MP-SN、ANS-Me/N-Me、U6-PP、L6-MP、OB的变化比较均具有统计学差异。结论:微种植体支抗压低磨牙可有效矫治高角开牙合病例,是一种疗效确切且经济便捷的治疗方法。

Abstract: Objective: To investigate the feasibility of treating high-angle and open-bite cases by micro-implant anchorages. Methods: 9 patients with high-angle and open-bite were included. Micro-implants were placed on the posterior alveolar bone of the upper and lower jaw in the four quadrants, and then molars were intruded lightly and continuously. The lateral cephalometric X-ray films were analyzed before and after treatment. Results: After treatment, normal overbite and overjet were obtained for all patients. Upper and lower molars were intruded effectively with the mandibular counterclockwise rotated. SNB, ANB, MP-FH, MP-SN, ANS-Me/N-Me, U6-PP, L6-MP and OB values were significantly changed after treatment. Conclusion: Intruding molars by micro-implant anchorages can treat high-angle and open-bite cases effectively.
