Autogenous Tooth Transplantation For Repair Of Oroantral Communication

A case of successful autogenous tooth transplantation performed simultaneously to repair maxillary sinus communication following a tooth extraction, achieving favorable outcomes. The patient presented with persistent pain after multiple treatments at an outside clinic. Subsequent examination at another institution revealed a perforation at the floor of the pulp chamber of tooth 26. Upon referral to our hospital, it was proposed to extract tooth 26 and perform simultaneous autogenous tooth transplantation for repair. During the operation, maxillary sinus communication was identified; autogenous tooth transplantation was then performed to close this communication while also replacing the missing tooth. A CGF membrane was applied to the perforation area . Two months post-surgery, root canal treatment was performed. At the five-month follow-up, the patient reported no subjective discomfort, and the transplanted tooth exhibited good healing. There was no mobility (-), no percussion pain (-), and no signs of gingival inflammation. Radiographic examination showed a visible periodontal membrane around the transplanted tooth, with osseous formation observed in the surrounding area. Follow-up CT scans revealed a clear sinus cavity, new bone formation at the sinus floor, and no pathological changes at the root apex. Autogenous tooth transplantation not only effectively seals maxillary sinus communication but also promotes bone regeneration at the extraction site and restores the missing tooth without causing additional trauma to the patient. This approach provides clinicians with a simple and reliable method for repairing maxillary sinus perforations, quickly restores missing teeth, and reduces the overall treatment duration.
