| 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) |

| #1) 19215747 | Fugazzotto/2009 | | Narrative Review | | Key results | A 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) 15237872 | Van Dalen/2004 | | Narrative Review | | Key results | Two-unit cantilevered resin-bonded FPDs were found to have significantly greater longevity than two abutment resin-bonded FPDs. | | #3) 16803807 | Botelho/2006 | 269 prostheses placed in 214 patients | Retrospective study | | Key results | In 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. |
