MANEJO QUIRÚRGICO, REGENERACIÓN BIOLÓGICA Y FORMACIÓN RADICULAR EN AUTOTRANSPLANTES DENTALES: SCOPING REVIEW.

Abstract

Dental autotransplantation is an effective therapeutic alternative for the rehabilitation of young patients with tooth loss. Unlike implants, it preserves vital structures such as the periodontal ligament, promoting a more physiological biological integration.
Objective: To explore and map the scientific evidence on surgical, biological, and root development factors that influence healing and clinical success of dental autotransplantation in young adults.
Methods: A scoping review was conducted following PRISMA-ScR guidelines. Articles published between 2015 and 2025 in PubMed, Elsevier, Epistemonikos, and SciELO were included, focusing on clinical, histological, and biological outcomes in humans.
Results: Of the 18 studies selected, clinical success was associated with multiple interrelated factors: atraumatic surgical technique, planning with 3D guides, preservation of the donor tooth in physiological solution, adequate patient selection, and stage of root development. Immature teeth with 50–75% root formation showed higher revascularization rates and lower risk of complications. The use of PRF and PRGF promoted healing by stimulating angiogenesis and preserving the viability of the periodontal ligament.
Conclusions: Successful dental autotransplantation requires a comprehensive approach that considers both surgical and biological factors. Although no standardized technique currently exists, the combination of advanced planning, accurate patient selection, and adjuvant biomaterials improves the clinical prognosis and integration of the transplanted tooth.
