Autogenous tooth transplantation: a reevaluation.

This paper discusses whether autogenous tooth transplantation can survive as an option in the future dental armamentaria. Clinically, successful transplants must show a radiolucent space between the roots and surrounding bone. There must be no evidence of ankylosis, no permanent root resorption, and no inflammation. Histologically, the criterion of success is a normal and functional periodontal ligament between the root surfaces of transplants and the bone or gingival connective tissues. Case reports are presented to illustrate replantation or transplantation of teeth. Possible donor teeth are those with the proper amount of viable periodontal ligament, single-rooted teeth, third molars, and malpositioned or impacted teeth. The transplantation procedure involves extraction of the donor tooth, measurement of the root form and amount of periodontal ligament, preservation of donor tooth, preparation of recipient socket, positioning of donor tooth, suturing, and temporary splinting.
