The replacement of a tooth (or teeth) that has been avulsed from its alveolar socket due to accidental or non-accidental trauma. Reimplanted teeth require stabilization with a functional splint, such as one made of resin composite, for about 7–10 days to allow periodontal ligament reattachment to take place. The splint should allow some normal tooth movement within the socket to avoid ankylosis. Factors affecting the success of reimplantation include the time from avulsion to reimplantation, the storage medium, the splinting time, and the viability of the pulp. Unwanted sequelae of reimplantation are root resorption or ankylosis.
