摘　　要：目的:应用种植支抗压入伸长磨牙,评价磨牙压入的安全性、有效性,探讨支抗钉的植入部位。方法:选择10例患者,男2例,女8例。年龄25～53岁,平均33岁。上颌磨牙由于对牙长期缺失而伸长,咬合于对颌牙槽嵴黏膜,妨碍牙列修复治疗。利用种植支抗,使用弹性牵引力根向压入伸长的磨牙。结果:10例患者的缺牙区均获得了足够的义齿修复垂直间隙,成功进行种植牙修复。伸长磨牙平均压入3mm,治疗时间平均3.5个月。治疗过程中未发现明显的牙根吸收、牙髓坏死、明显的牙松动。未见牙根尖进入上颌窦。结论:磨牙伸长可通过种植支抗技术予以安全有效地压入,为缺失牙修复创造足够的义齿修复空间。PURPOSE： The purpose of this study is to evaluate the efficiency and security of self-drilling mini-screw implant anchorage for molar intrusion, to achieve the right position of the mini-screw implant. METHODS： Ten patients with overerupted maxillary molars were selected, aging from 25 to 53 years old, the average age was 33 years old. There were 2 men and 8 women. All the overerupted molars were intruded in gingival direction with mini-screw implants anchorage. RESULTS： The mean intrusive movement of the overerupted maxillary molars was 3 mm, the mean treatment time were 3.5 months.All of the missing teeth were treated by prosthetic treatment. No obvious root resorption, pulp necrosis and tooth loosen were found. CONCLUSIONS： Significant true intrusion of maxillary molars could be obtained by mini-screw implant as bony anchorage.Supported by Shanghai Leading Academic Discipline Project （Grant No.Y0203） and Research Fund of Science and Technology Committee of Shanghai Municipality （Grant No.05B224）.
