Endodontic endosseous implants (EEI) have been historically advocated to retain teeth or roots that have been compromised by trauma, periodontal disease, and resorption due to orthodontic tooth movement. The EEI has an advantage in that it can be totally intraosseous without communicating with the oral cavity. While successful in some cases, many failures resulted, which led to their falling out of favour during treatment planning. Presently their use has been significantly overshadowed by the use of endosseous implants following tooth extraction. The paper will discuss the history of EEI, their primary causes for failure, and tissue responses to their placement, coupled with a case of long-term success using this modality for tooth retention following trauma.
