Title Conventional Single Tooth Fixed Partial Dentures (FPD) vs. Resin-Retained Fixed Partial Dentures
Clinical Question For the replacement of a single missing tooth, how do cantilevered resin-bonded FPDs compare to conventional cantilevered FPDs in terms of longevity?
Clinical Bottom Line Conventional FPDs tend to have greater longevity than resin-retained FPDs, though cantilevered (single-retainer) resin-retained FPDs have greater longevity than those with two retainers, and they represent a reasonable treatment option. (See Comments on the CAT below)

(level of evidence)
#1) 19215747Fugazzotto/2009Narrative Review
Key resultsA review of the current literature was performed and retrieved the five year survival rates for single-tooth replacement options as follows: three unit FPD: 94%; cantilevered FPD: 91.4%; resin bonded bridge: 87.7%.
#2) 15237872Van Dalen/2004Narrative Review
Key resultsTwo-unit cantilevered resin-bonded FPDs were found to have significantly greater longevity than two abutment resin-bonded FPDs.
#3) 16803807Botelho/2006269 prostheses placed in 214 patients Retrospective study
Key resultsIn a study recalling patients with two-unit resin-bonded FPDs after a period of at least 24 months, the survival rate was found to be 95.5%.
Evidence Search PubMed search performed with the following MESH terms: “Denture, partial, fixed,” and “Denture, partial, fixed, resin-bonded.” Limits were set initially to include only review articles and systematic reviews; limits were removed to produce more search results.
Comments on
The Evidence
Fugazzotto reviewed the current literature and two meta-analysis - one determined the 5 year survival for FPDs to be 94%, and another determined the 5 year survival for FPDs and cantilevered FPDs to be 93.8% and 91.4%, respectively.
Applicability This information applies directly to anyone seeking replacement a single missing tooth, especially those with options limited by financial considerations or those for which other options may be contraindicated.
