A Novel Autologous Root Slice Replantation Technique Applied for Immediate Implantation of Maxillary Central Incisors: A Case Report With 6-Year Review.

This case study describes a novel approach to autologous tooth transplantation combined with immediate implantation. This article presents a 6-year follow-up observation of a 22-year-old male patient who requested oral implant restoration after a fracture of the maxillary anterior tooth caused by trauma. Treatment involved immediate implantation of the maxillary central incisors using a novel autologous tooth transplantation technique called autologous root slice replantation (ARSR). It avoided the absorption of soft and hard tissues on the labial side after immediate implantation of the maxillary anterior teeth. Moreover, the implant area and its surrounding soft tissues were healthy without obvious inflammation. The ARSR develops the application of autologous tooth transplantation combined with immediate implantation, providing a new solution for esthetic implantation in the anterior teeth area.
