Abstract

The appropriate treatment for eruption guide of impacted teeth necessitates the formulation of a comprehensive treatment plan, which is dependent upon a number of factors such as the condition of the deciduous teeth, dental and skeletal relationship, dental age of the patient, willingness of the patient to undergo extensive dental treatment and financial considerations. If the etiology of the eruption disturbance has been identified, the elimination of the causes and various procedures can be used for eruption guide. Particularly the transplantation is a valuable alternative to extraction of impacted teeth, where surgical exposure and subsequent orthodontic realignment are difficult or impossible. This report present three cases of autotransplantation of impacted maxillary canine. As the result in these cases, atraumatic removal of donor tooth during operation is prerequisite to an optimal clinical result. Due to a high possibility of pulp necrosis, endodontic treatment of fully developed transplanted teeth should be undertaken. In complex case, autotransplantation can save time and less expensive than orthodontic forced eruption. Recipient socket should be prepared to a size that is slightly larger than the root of the donor tooth, and can be prepared with open or close procedure depends on root size of donor tooth and buccolingual width at transplantion site.
