Abstract:
Objective: To observe morphological change and diversity of periodontium and alveolar bone after tooth transplantation into artificial tooth socket. Methods: 6 dogs were divided randomly into 2 groups: 2 dogs were used as the controls and 4 used for the experiment. In the control group 4 teeth were autotransplanted into the inherent sockets. In the experiment group 4 teeth were autotransplanted into the artificial sockets. The dogs were sacrificed at the 16th week after operation. The healing condition of periodontal tissue and the remodeling of alveolar bone were examined. Results: None of the transplanted teeth in both groups was loosen or dropped. Mircro-CT examination showed that cancellous bone and bone trabecula around the transplanted teeth lined tightly,no significant difference of bone trabecula thickness was observed between the 2 groups. Hard tissue slice examination revealed that parodontium of both groups grew and adhered to the teeth,and the quantity of new-born bone between the top of alveolar ridge and the neck of transplanted teeth was fundamentally the same in the 2 groups. Conclusion: Autotransplantation of teeth into the artificial socket is similar to that into inherent socket.
