微螺钉种植体支抗在牙性平面倾斜矫治中的临床应用

Treatment of teeth-induced inclined occlusion plane with microscrew implant

目的:探索微螺钉种植体支抗在牙性平面倾斜矫治中的临床疗效。方法:13例牙性平面倾斜病例,在牙齿伸长最严重部位的牙根间膜龈联合处颊侧植入微螺钉种植体,以橡皮圈作为力源,利用持续轻力(80g/牙)对牙齿进行垂直向调整,纠正倾斜的平面。结果:13例患者均表现出良好且稳定矫正效果,较好地矫治了倾斜的平面。结论:微螺钉种植体支抗能够有效矫正牙性平面倾斜,明显改善患者的面型。

Objective： To investigate the effects of microscrew implant anchorage （MIA）on teeth-induced inclined occlusion plane treatment. Method： 13 orthodontic patients with teeth-induced inclined occlusion plane were treated with MIA and fixed appliance.Microscrew implants were implanted into the mesial-buccal or distal-buccal alveolar bone of the most serious elongation parts of the teeth arc. The implants were ligated with ligature wire to elongation teeth and loaded 80 g / teeth moment. The treatment period, methods and effects on molar intrusion or extrusion were evaluated. Result： 11 of the patients showed good results and stable correction with average period of 6.1±1.4 months, 2 of them with mild recurrence. Conclusion： MIA can effectively correct the teeth of teeth-induced inclined occlusion plane, significant improvement in pa- tient′s face.
