Protocol for immediate implant replacement of infected teeth

Extraction and immediate implant placement has become routine procedure due to reduced treatment time and the preservation of anatomical structures. However, in many cases, this technique involves teeth with different degrees of tissue compromise due to underlying infections. Until now, the degree of implant compromise has not been described, nor has a clinical management protocol been established for these cases. The aim of this article is to report the clinical results of a protocol used for immediate implant placement and provisionalization in infected extraction sockets. A classification of the implant surface compromise (in contact with previously infected tissue) is also described to facilitate the comparative analysis. It is possible to maintain the benefits of immediate implant placement and provisionalization in infected sites by applying a clinical protocol that considers antibiotic therapy, a thorough curettage of the infected tissue, antisepsis, and sufficient primary implant stability.
