Autotransplantation is the transplantation of organs, tissues, or even particular proteins from one part of the body to another in the same person (auto- meaning "self" in Greek).

The autologous tissue (also called autogenous, autogeneic, or autogenic tissue) transplanted by such a procedure is called an autograft or autotransplant.

It is contrasted with allotransplantation (from other individual of same species), Syngeneic transplantation (Grafts transplanted between two genetically identical individuals of the same species) and xenotransplantation (from other species).

A common example is the removal of a piece of bone (usually from the hip) and its being ground into a paste for the reconstruction of another portion of bone.

Indications
Autotransplantation of teeth can be considered in the following circumstances:
 * Movement of impacted or severely ectopic teeth to their correct position if conventional surgical exposure and orthodontics is not appropriate.
 * Management of congenitally absent teeth in one arch with crowding present in the other arch.
 * Premature loss of permanent dentition from caries, trauma, iatrogenic damage or developmental abnormalities. The tooth of choice to replace a tooth missing in the anterior maxillary region is the maxillary second premolars. Poor prognosis first permanent molars can be replaced with third molars

Autotransplantation has the best outcome in growing patients with some root development complete but incomplete development at the apex. If fully developed, autotransplantation can still be successful if an RCT is performed prior to autotransplantation or within 4 weeks following. . It has been suggested that tooth autotransplantation may be a successful alternative to osseointergrated dental implants in growing patients, as osseointergrated dental implants are contra indicated in growing patients as they do not grow down with the developing dentition and become fused to the bone.

Contraindications
Contraindications include the autotransplantation of deciduous teeth, transplant to an infected site, if the donor tooth is already restored and if the patient has poor oral hygiene and compliance
