Autotransplantation or immediate implant for non‑restorable posterior teeth? New meta‑analysis says both work — when to choose the tooth
A 2026 systematic review and meta‑analysis found similarly high short‑ to mid‑term success for immediate implants and autotransplanted mature teeth; choice should be individualized to anatomy, donor availability and the restorative plan.
A new systematic review and meta‑analysis in the Journal of Endodontics pooled 13 cohort studies (7 implant arms, n=153; 6 autotransplant arms, n=189) that compared immediate implant placement with autotransplantation of mature donor teeth for replacement of non‑restorable posterior teeth. At 12 months pooled success rates were essentially identical (immediate implants 97.0% vs autotransplants 95.9%), and at 36 months implants remained at 97.0% while autotransplants fell to 90.3% — differences that did not reach statistical significance in the meta‑analysis. These results support that, in the short to mid term, both options can be successful when cases are well selected. ([pubmed.ncbi.nlm.nih.gov](
Clinical takeaways
- If you have an available donor tooth of suitable size and anatomy, autotransplantation is a viable, biologic alternative to an immediate implant for replacing a non‑restorable posterior tooth.
- Plan for cuspal coverage on autotransplanted teeth — the meta‑analysis found that providing an indirect restoration with cuspal coverage was associated with better 36‑month outcomes (statistically significant). ([pubmed.ncbi.nlm.nih.gov](https://pubmed.ncbi.nlm.nih.gov/42810678/))
- For mature donor teeth, coordinate timely endodontic care (and minimise extra‑oral time); technique and restorative sequencing matter more than the choice of implant versus transplant in many cases.
