SP-6 - The Tooth “Implant”: Applications and Outcomes of Intentional Replantation and Autogenous Transplantation

When orthograde retreatment and apical microsurgery are considered unfeasible, when they fail to resolve persistent endodontic infection, or when the remaining tooth structure is deemed non-restorable, the tooth is usually extracted and replaced with an implant or another prosthetic device. Alternatively, when clinical conditions permit, the tooth can be extracted, manipulated extra-orally and replanted (Intentional Replantation, Surgical Extrusion), or a non-strategic tooth can be transplanted into the socket of the extracted tooth (Autogenous Transplantation). These seemingly radical but rather simple procedures offer predictably good outcomes when the biologic principles of tooth replantation are respected.
This lecture will discuss the procedures of Intentional Replantation/Transplantation in a contemporary context, as predictable means for retaining otherwise “untreatable” teeth to greatly benefit patients. Strict guidelines for case selection, a step-by-step protocol and a variety of clinical applications will be outlined and illustrated with typical cases. Reported outcomes will also be highlighted for various clinical applications of both procedures.
