The aim of this literature review is to evaluate the outcomes of implants placed after extraction of teeth with infections of endodontic origin. An electronic search was performed through electronic databases (Medline and Embase) using the terms "immediate implant," "post-extractive implants," "endodontic infection," "infected site," and "extraction socket" combined with the use of Boolean operators ("AND" and "OR"). Only articles on human subjects were considered. At least 12 month of mean follow-up was required for inclusion. No restriction was placed regarding study design. Ten studies were included in this review. Survival rates ranged from 92% to 100%. A total of 497 implants were placed in sites with endodontic infection. In nine studies the use of bone substitutes was associated with immediate implant placement. Because of the low number of included studies and the heterogeneity of study design, more well-designed studies are required to assess the relevance of this treatment alternative.
