前牙龈下牙折的磁力牵引

龈下牙折在临床上较为常见,如何进行完善的修复治疗是摆在临床医师面前的一个难题.目前已得到认可的修复方法包括用常规固定矫治器对残根进行正畸牵引,或进行临床牙冠延长术,或将断根拔出后进行修复.本文报道了采用磁力正畸对龈下牙折的断根进行正畸牵引,配合修复治疗获得了良好的临床效果,综合满足了患者美观和功能的需要.

Abstract：

Treatment of the case with sub-gingival crown fractures was a challenge to clinicians. Acceptable treatment options include the extrusion of the remaining root with a conventional orthodontic appliance, surgical crown lengthening, or root extraction with prosthetic tooth replacement. In this case, orthodontic extrusion with magnets was used to extrude sub-gingival crown successfully. After prosthodontic treatment, both esthetics and function waere satisfiec.
