摘　　要：目的 初步分析运用种植支抗牵引埋伏牙的临床效果,探讨正畸治疗中选择种植支抗牵引埋伏牙的适应证及该项治疗的特点.方法 对6例埋伏牙患者的8颗埋伏牙运用种植支抗进行牵引治疗,牵引后对牙齿的松动度、牙髓活力等各项临床指标进行检查,并摄术前术后曲面断层片对牵引效果进行观察.结果 6例患者经3～5个月的牵引后埋伏牙萌出,牙髓活力正常,未发现牙根吸收.与以往的方法相比,运用种植支抗牵引埋伏牙支抗充足,患者不适感降低.结论 运用种植支抗牵引埋伏牙为埋伏牙牵引治疗提供了一种方法选择.Objective To investigate effectiveness and efficiency of impacted teeth correction with implant anchorage. Methods Eight impacted teeth in six patients were corrected with implant anchorage after surgical exposure. Tooth mobility and pulp vitality were evaluated. Dental radiographs were taken before and after treatment. Results Good results were obtained and the impacted teeth were erupted within 3 - 5 months after orthodontic traction. The pulp of the teeth was vital. Conclusions The implant anchorage could be used in the treatment of impacted teeth.
