The Effect of a Tooth Gingival Transplantation on Periodontal Healing

We investigated the effects of a tooth gingival transplantation (TGT) on autologous tooth transplantation using tooth with both periodontal ligament and gingiva. Stabilization period, degree of tooth mobility, and periodontal pocket depth (PPD) were compared with those of transplanted teeth using the conventional method (tooth with periodontal ligament). The subjects were 76 healthy adults (56 cases for the conventional method and 20 cases for TGT). Stabilization period of the tooth was shorter in the cases of TGT than that of the conventional method. Degree of tooth mobility was almost the same for TGT and the conventional technique. The value of PPD at 12 weeks after operation was better in the TGT group than in the conventional method group. The results for both stabilization period and PPD were better in TGT than in the conventional method, indicating low risk for periodontal disease in TGT.
