Abstract
Autotransplantation is the transplantation of the patient¡¯s own tooth from one site to another, wherethe recipient site may be either an extraction socket or a surgically prepared site.It is a viable treatment option for the replacement of missing teeth when an appropriate donor tooth is available, such as a third molar, a premolar in a crowded arch, or a supernumerary tooth with a high survival rate that is reported to range from 74 -100%.The survival and success of an autogenously transplanted tooth is highly dependent on the health of the periodontal ligament that is attached to its root surface.Therefore, minimizing damage to the donor tooth root surface and extraoral time is critical. For this purpose, CBCT-fabricated RP modelsmayusedin the surgical preparation of the recipient site Alternatively, less accurate wax models may bemanually fabricated from panoramicradiographs and study casts. Furthermore, surgical guides containing stainless steel drill tubes as used in implant surgeries have been suggested.Additionally, animal studies have shown that when transplanted teeth lack viable cells on their root surfaces, using cultured autologous periodontal ligament cells could enhance healing.Moreover, in an effort to store teeth to be transplanted later on, cryopreservation and hypothermic preservation methods are being studied. Despite these successes, there are possible complications associated with autotransplantation including inflammatory root resorptionand replacement resorption.
