Autogenous Tooth Transplantation Assisted By An Autonomous Dental Surgical Robot

Autogenous tooth transplantation involves transferring a tooth within the same patient, requiring precise socket preparation that is technically challenging. This case demonstrates a robot-assisted technique to improve precision. A 46-year-old male with an unrestorable mandibular first molar (#46) underwent transplantation using the erupted third molar (#48) as the donor. Preoperative CBCT revealed #48′s bifurcated, longer roots necessitating osteotomy expansion. CBCT and intraoral scans were integrated into Dental Navi software for virtual planning, enabling automated osteotomy trajectory calculation. The robotic system performed osteotomy autonomously via foot pedal control, minimizing manual intervention. The donor tooth was transplanted and splinted, followed by root canal therapy at 2 weeks. Six-month follow-up showed successful outcomes. This case report presents a preliminary application of an autonomous dental robotic system for performing patient-specific osteotomy with complex geometric configurations in the jawbone, potentially facilitating autogenous tooth transplantation. This initial attempt suggests that the technological approach may help reduce procedural complexity and could contribute to improved postoperative healing efficiency. Robotic assistance reduced surgical difficulty while preserving alveolar bone. The planned osteotomy enhanced primary stability, shortening healing time.
