摘　　要：目的评价应用种植支抗和铸造支架压低上颌第二磨牙的效果。方法选择因下颌第二磨牙长期缺失而导致对牙合牙伸长、影响牙列修复的患者8例,年龄24～52岁。利用微种植钉作稳定支抗,利用铸造支架进行力量转移传导,橡皮链压低伸长的磨牙。结果 8例患者磨牙平均压低3.2 mm,缺失牙均获得足够的垂直向间隙,成功地进行义齿修复。治疗时间平均5个月。治疗中未发现明显的牙根吸收、牙髓坏死及牙齿松动。结论种植支抗结合铸造支架可以安全压低伸长的磨牙。Objective To evaluate the effects of microimplant anchorage combined with casting appliance on the intrusion of extruded upper second molars. Methods The 8 cases were 24-52 years old. They had lost one lower second molar for a long time, which resul- ted in protruded upper second molars and no space for restoration. Micro-implants were used as absolute anchorage and casting appli- ances as the force transmission system. The power chain was the tool to intrude prolonged molars. Results The average intrusion of the eight cases was 3.2 mm. The achieved vertical space was enough for the restoration. Denture restoration was completed. The aver- age treatment period was 5 months. There was no obvious root resorption,pulp necrosis and teeth loosening. Conclusions Combina- tion of microimplant anchorage and casting appliance is a useful force system to intrude protruded utaper second molars.
