摘要:

目的 评价年轻恒牙完全脱位再植后的愈合方式,对不同发育阶段年轻恒牙再植术后的疗效进行总结,为更好保留患牙的美观与功能提供参考。方法 回顾分析30颗完全脱位年轻恒前牙,根据国际牙外伤协会治疗指南进行治疗。评价再植后年轻恒牙牙周组织愈合方式,分为牙周膜愈合、表面吸收愈合、替代性吸收(骨粘连)、炎性吸收。结果 30颗完全脱位的年轻恒牙再植后,其中7颗为牙周膜愈合,占23.3%;1颗为表面吸收愈合,占3.3%;13颗为替代性吸收,占43.3%;9颗为炎性吸收,占30.0%。结论 年轻恒牙发生完全脱位,再植后愈合方式受多种因素影响。当出现不良的愈合方式限制颌面部发育时,一定要及时干预,减少患者生理和心理的创伤。
