8세 男兒의 上顆右側 中切齒의 再植症例

生物學的임프란트症例

This is a case of replantation of upper right centeral incisor in a 8-year-old boy. The tooth was avulsed because of falling down. The patient visited our dental clinic after 12 hours passed with avulsed tooth. The tooth was treated endodontically, replanted and fixed with acid etching technique for 4 weeks. Many investigators have reported that root resorption and ankylosis of replanted is common and depend on extraoral period of avulsed tooth, storage condition, and etc. Since, in this case, extraoral period was long and the tooth was severe dried, extensive root resorption and ankylosis was observed raiographically and clinically. However, 12 months after replantation, it remains a satisfactorilly functioning tooth. We have observed, in spite of dislodgement of replanted tooth after several years, replantation is more biological and economic than prosthetic treatment.
