38.) Trasplante Dentario Método terapeutico en Ortopedia Maxilar/Ortodoncia

Primera parte

Autotransplantation is the surgical procedure of removing a tooth and replanting it within the same individual. This treatment concept was first described thoroughly by John Andreasen and Poulsen in 1990, but one of the first tooth transplantations was done in England by John

Hunter in the late 18th century. Modern interdisciplinary treatment concepts involve a wide variety of specialists and make comprehensively treated cases with a perfect result possible. With the ongoing development of dental implants they more and more become part of our orthodontic planning, but there are still specific indications in which dental implants are either impossible or the second choice. The lecture will focus on the indications of autotransplantations and the basic treatment concepts. We shall have a closer look at the biologic basis, the surgical procedures and techniques of transplantation of vital teeth, and shall discuss autotransplantation in adults as well.

Segunda parte

The second part of the lecture shows treatment details and we shall look at possible problems during the pre- and postoperative orthodontic tasks and how to prepare the autotransplantation site prior to the surgical intervention. Due to the lack of experience of the surgeon, a traumatic surgical technique, or other possible trauma to the freshly transplanted tooth, or wrong timing of the procedure, the loss of the transplant, the development of root resorption, or a later ankylosis might be possible. A strict treatment regimen and a perfect teamwork between orthodontist and surgeon are necessary to avoid these undesired side effects. Treatment alternatives are discussed including orthodontic space closure, extraction of contra-lateral teeth, leaving of deciduous teeth, prosthodontic bridgework, or dental implants. With the help of a check-list it will be easier for dentists and orthodontists to decide on one or the other treatment method.
