(TC42) One Last Chance for Natural teeth When There's No Way Other Than Extraction

Severe dental problems including periapical lesion, vertical root fracture, and advanced alveolar bone loss cannot always be fully treated with conventional root canal therapy or periodontal treatment, leaving extraction as the only option. Now, however, with the significant improvement in implant technique, clinicians usually choose to extract teeth with poor prognosis rather than treating them. However, implants cannot fully take place of the natural teeth in many circumstances. So, intentional-replantation or autotransplantation can be considered as a last resort for hopeless teeth. These treatments do not seem to be widely practiced since there are concerns, such as damage to teeth during extraction and possible tooth resorption or ankylosis. However, if cases are properly selected and exact surgical processes are performed, these treatments would provide favorable long-term success rates with reduced complications. The purpose of this table clinic is to suggest a treatment protocol for successful Intentional-replantation and autotransplantation through the following three cases.
1) chronic periapical-periodontitis untreated by conventional RCT - intentional-replantation (five years follow up)
2) periodontally involved teeth - intentional-replantation with heterogenous bone graft (10 years follow up)
3) periodontally involved teeth - Transplantation with heterogenous bone graft (four years follow up)
