Autogenous tooth transplantation in a severely insufficient alveolar ridge without a bone graft: Two case reports

Abstract

© 2019 The Authors Background: Autogenous tooth transplantation is a simple technique that typically results in a satisfactory outcome. However, there are still many challenges, such as insufficient alveolar bone and tooth vitality. The aim of this study was to report two clinical cases of autogenous tooth transplantation with severe alveolar bone defects, one tooth with immature root development and one with mature root formation. Methods: Clinical and radiographic data of the two cases were collected over three and twelve years. Results: The two cases of autogenous tooth transplantation demonstrated successful bone regeneration without using a bone graft. The gingiva regained their normal characteristics and the teeth maintained their vitality with both immature- and mature-rooted transplants surviving with almost complete pulp obliteration and without endodontic treatment through the follow-up period of twelve years. Conclusions: Autogenous tooth transplantation in a severely insufficient alveolar ridge can be achieved based on standard success criteria. Furthermore, endodontic treatment might not always be necessary when the transplanted tooth has a completely formed root with a closed apex.
