Statement Of Problem:
Evidence is limited on the efficacy of narrow-diameter implants (NDIs) in the posterior jaw.
Purpose:
The purpose of this systematic review was to assess the survival of NDIs and provide guidelines for their safe use.
Materials And Methods:
Electronic search of the English-language literature enriched by hand search to identify suitable publications was made. Only peer-reviewed clinical studies published from January 1990 through March 2014 were included.
Results:
Seventeen studies with a total of 1644 implants met the inclusion criteria, with an observation period from 1 up to 12 years. The mean survival rate of 98.6% was reported. Technical and other complications were observed.
Conclusion:
Short-term clinical data suggest that NDIs may serve in the posterior jaw as an alternative to standard-diameter implants. However, certain clinical conditions must be observed to assure long-term success.
