S-7 - Tooth Autotransplantation, Intentional Replantation and Surgical Extrusion. the Technique Evolution over 15 Years

Tooth autotransplantation, intentional replantation and surgical extrusion are different treatment options with a similar principle; the preservation of the periodontal ligament (PDL) in order for the tooth to heal and be newly articulated with the bone.
Tooth autotransplantation is defined as the surgical movement of a tooth from one alveolar socket to another, either after extraction or by surgically preparing the recipient site in the same patient, it is a viable option to replace lost teeth or poor prognosis teeth. Thus, both function and preservation of the alveolar bone crest is maintained. Its success is associated with healing of the PDL and pulp tissue, absence of root resorption, soft tissue healing, and radicular formation. Intentional replantation is the atraumatic extraction of a tooth enabling the clinician to do a procedure (mostly endodontic microsurgery, or cervical resorption treatment) in less than 15 minutes (extra-alveolar time) in teeth in which, otherwise, access would not be possible. Surgical extrusion consists of atraumatic luxation and coronal repositioning of a tooth with in its same socket, this with the purpose of exposing root resorption, root fractures or decay and treat it, leaving sound tooth structure subgingival.
Over the last 15 years these techniques have had a great evolution due to the introduction of cone beam computed tomography (CBCT), intraoral scanning, 3D planning software, 3D printers and computer aided dynamic navigation devices. All this technology enables a more predictable, faster and safer procedure with lower extra-alveolar times. In this lecture several clinical cases, with a proper follow up period, show the rapid progress of the technique always based in the best scientific evidence available and trying to inspire Endodontists to have this type of treatments as valid options to help their patients.
