摘　　要：目的评价前牙龈下3 mm以内残根正畸牵引加纤维桩核全瓷冠修复的效果。方法选择61例患者102颗前牙龈下3 mm以内残根,均经完善的根管治疗后,采用正畸牵引术:在控制好支抗和力量柔和而持久弹性橡皮圈牵引出残根面至少1.5 mm牙本质肩领的高度,并遵从生物学宽度2.04 mm要求,矫治结束保持6周稳定后纤维桩核全瓷冠修复。结果 61例患者102颗残根中,随访1~5年,失访1颗;成功91颗(成功率90.1%),失败10颗(9.9%),失败中主要桩核折断2颗,桩核冠脱落1颗,牙龈水肿2颗及牙周袋形成1颗,牙根松动3颗,牙根及牙槽骨混合性吸收1颗。结论对龈下3 mm以内残根者,采用正畸牵引加纤维桩核全瓷冠修复效果较满意。Objective To assess the curative effect of repairing residual roots with orthodontic traction plus fiber posts cores and all ceramic crown within 3 mm beneath the gingiva. Methods 61 patients were selected who were with 102 front gingival residual roots. After root canal therapy, they were treated with orthodontic traction： with well controlled anchorage and enduring elastic rubber rings, the residual roots were tracted out at least 1.5 mm of ferrule. According to the requirement of 2.04 mm biological width, they were repaired with fiber posts cores and all ceramic crown six weeks after orthodontic treatment. Results Follow-up observation of 1-5 years showed that among 61 patients with 102 gingival residual roots, except one patient failed to be followed, 91 residual roots were successfully restored （90.1%）; 10 failed （9.9%）, among which 2 with broken fiber posts cores, one with post-core crown falling off; 2 with gingival oedema; one with periodontal pocket; 3 with loose dental roots, and 1 with mixed resorption of dental root and alveolar bone. Conclusion The curative effect of restoring residual roots within 3mm beneath the gingiva with orthodontic traction plus fiber posts cores and all ceramic crown is satisfactory.
