Tooth Transplantation With Sticky Bone for Vertical Bone Defects: A 4‐Year Follow‐Up Case Report

Background Severe buccal vertical bone defects accompanied by combined periodontal–endodontic lesions are challenging to manage, and evidence regarding the long‐term outcomes of digitally assisted autotransplantation combined with sticky bone grafting remains limited. We aimed to report a case of digitally assisted tooth autotransplantation combined with autologous alveolar bone and sticky bone grafts for the reconstruction of a severe buccal vertical defect. Case Description A 23‐year‐old female patient underwent autotransplantation of the right maxillary third molar (#1) to replace the left mandibular first molar (#19) affected by a severe buccal vertical bone defect in July 2020. The autotransplantation procedure involving the donor tooth and the attached autologous alveolar bone from Tooth #1 was simulated using surgical planning software to determine the optimal rotation and angulation of the donor tooth. Buccal bone augmentation for the vertical defect associated with severe furcation involvement was achieved by transplanting the distal alveolar bone of Tooth #1 in combination with sticky bone grafts. The tooth was stabilized with resin fiber tape for 4 weeks. Conclusion At the 4‐year follow‐up, no clinical or radiographic abnormalities or signs of infection or inflammation were observed. This approach may represent a feasible option for selected cases with severe buccal vertical bone defects.
