(PR96) Clinical Outcomes of Guided Autotransplantation Procedures

Autotransplantation is a viable treatment option that replaces hopeless teeth by transplanting a non-strategic sound tooth in the same individual. Viability and maintaining the cells of the donor tooth periodontium is key for a better prognosis and to avoid potential ankylosis. This treatment has not been widely practiced due to early reports of failure and complications. The aim of this study was to present the digital workflow and outcomes of guided autotransplantation procedures. Four cases were treated at the graduate endodontic clinic at King Abdulaziz University and were suitable for autotransplantation procedure. Preoperative CBCT studies and virtual planning were completed for all cases. 3D printed replicas were prepared and, for one of the cases, a surgical guide. The four cases had different presentations and were all managed differently with full documentation. All cases had a minimum of 12 months follow up with clinical, radiographic, and photographic documentation. None of the cases developed a periapical pathosis nor ankylosis. On the other hand, they demonstrated a continuation of root development in terms of length and dentin thickness for those with open apices and, in one case, a notable pulp space narrowing. Pulp sensibility test was recorded every six months but a delay in response was noted for both cold and EPT tests at follow-up visits 18 months later. The digital-assisted planning in guided-autotransplantation procedures improved the treatment outcomes and predictability. Our report highlighted the importance of autotransplantation as a viable treatment option and we need to encourage practitioners to embrace it again.
