Tooth Autotransplantation With Attached Gingiva Preservation Technique

Objectives: This clinical innovative case series describe an autotransplantation attached gingiva preservation technique that positions the connective tissue of the donor tooth to form a biological barrier that resulted in the vertical growth of alveolar bone.
Methods: Mandibular third molars were autotransplanted immediately after extraction of the adjacent second molar. The third molar distolingual attached gingiva was preserved in the extraction process. Two cases were followed-up for two years.
Results: In the follow-up visits, the autotransplantion was asymptomatic and possessed natural periodontal tissue with biological mobility. Radiographic examination indicated the absence of apical radiolucency without endodontic treatment, and significant vertical growth was shown in the distal alveolar bone
Conclusions: Third molar autotransplantation using attached gingiva flap preservation technique can lead to optimal periodontal healing and a promising prognosis in vertical alveolar bone growth.
