目的：探讨种植体和微型种植体支抗在正畸与修复中的联合应用的可行性，并观察临床效果。方法：选择24例下颌磨牙缺失对牙伸长需要做种植的患者。缺牙区植入ITI种植体，常规种植治疗。同时在对伸长的磨牙的近中腭侧和远中颊侧各植入一枚微型种植体，用橡皮链挂在颊、腭侧的种植体上，以压低伸长的对牙齿，定期更换并进行临床检查。结果：24例患者中，1枚微型种植钉松动脱落，余23例患者伸长牙平均压低2.4mm，平均压低时间为5.6个月，经种植修复后均获得满意的临床效果。结论：针对下颌磨牙缺失对牙伸长的病例，种植体和微型种植体支抗的联合应用，能达到最佳的修复效果。%Objective: To evaluate the clinical effects of combination application of implant and mini-screw implant as anchorage in orthodontic and renovation. Methods: Choose 24 patients who's mandibular molar had defected and maxillary molar had elongated>2.5mm. The patients' mandibular molar defect were received ITI implant installation under the normal treatment rules. At the same time, the extruded maxillary molar were treated with self-drillinng mini-screw implant as anchorage for intrusion. Rusults:1 patient's miniscrew implant were loosed and then lost because of peri-implant inflammation. Other 23 patients' maxillary molar were average intruded 2.4mm in 5.6 month. After ITI implant installed in par-tial edentulous area, the effect of the treatment were excellent. Conclusion: To the patients of mandibular molar defected and maxillary first molar elongated, combination application of implant and mini-screw implant as anchorage in orthodontic and renovation can obtain optimal results.
