LITERATURE REVIEW

as an Alternative to Endodontic Retreatment: A Review of
Literature

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.
Key Words: dental implants, postextraction sockets, apical periodontitis, immediate implants, treatment
planning
INTRODUCTION
O
rthograde primary endodontic therapy is an effective treatment, as
indicated by systematic reviews reporting success rates ranging between 31% and 100%1,2; the variability was mainly due to the inclusion criteria of the
studies and to the adopted criteria of success. In
cases of failures with persistent periradicular lesions,
secondary endodontic treatment was recommended,
and those outcomes were investigated in systematic
reviews.3,4 Reported success rates for nonsurgical or
surgical secondary treatment are greater than 70%

for both,3,5 and no significant difference in outcomes
between procedures was found.4,5 Endodontic surgery performed with a modern technique, that is,
with the aid of microinstruments, magnification
devices, and retrograde canal preparation through
the use of ultrasonic retrotips, has been reported to
achieve a success rate greater than 90% after 1 year.6
When the tooth pathologic condition cannot be
solved with endodontic retreatment (either orthograde or retrograde) or in the presence of root
fractures that become evident during diagnostic or
treatment phases, the extraction of the involved tooth
becomes the most indicated solution. Tooth extraction and immediate placement of dental implant in
the extraction socket is a viable and effective
technique in anterior zones7,8 and posterior regions,
though many requisites need to be considered.
The presence of active infection in the extraction
site is considered one of the main contraindications
