Abstract
This case report presents the 8-year follow-up result of autotransplantation on a healed alveolar ridge, with sinus elevation and autogenous bone grafting. We present a case of a 30-year-old male patient whose maxillary first molar was extracted 1 year ago. Under general anesthesia, after the membrane of the left maxillary sinus was elevated, an artificial socket was prepared on the healed alveolar ridge of the left maxillary first molar area. The left maxillary third molar was extracted and tried on the prepared artificial socket. The autogenous bone was harvested and grafted to the left maxillary sinus floor. The transplanted tooth received root canal therapy 2 months after surgery. During the 8-year follow-up period, no discomforts, periodontal ligament (PDL) widening, or root resorption signs were observed. Desirable bone remodeling signs and regeneration of PDL were observed on the radiograph. Therefore, autotransplantation can be a treatment option for healed and deficient alveolar ridge.
