Title	Which Lasts Longer: Implant or FPD?
Clinical Question	In an otherwise healthy adult patient missing just one tooth, does a fixed partial denture or an implant-supported crown last longer?
Clinical Bottom Line	When other factors are the same, single implant-supported crowns last longer on average than fixed partial dentures.
Best Evidence
PubMed ID Author / Year Patient Group Study type (level of evidence) 17936128 Torabinejad/2007 Included 46 ISC papers and 31 FPD papers out of 7701 papers identified Systematic Review with Meta-analysis Key results After 6+ years, the weighted success rates were 80% (79-82 95% CI) for FPD restorations and 97% (96-98 95% CI) for ISC restorations.
Evidence Search	Using PubMed, searched: "Denture, Partial, Fixed"[Mesh] AND "Dental Implants"[Mesh] AND survival
Comments on The Evidence	This systematic review compared not only FPD and implant-supported crowns but also no treatment for an edentulous space as well as root canal therapy and subsequent crown placement when the tooth in question had not been extracted yet.
Applicability	These findings would apply to most adult patients with adequate health and alveolar bone for dental implant placement who are missing a single tooth.

Comments and Evidence-Based Updates on the CAT (FOR PRACTICING DENTISTS', FACULTY, RESIDENTS and/or STUDENTS COMMENTS ON PUBLISHED CATs) by Mackenzi McAfee and Christopher Beard (San Antonio, TX) on 11/28/2017 A PubMed search on implant and FPD survival rates was done in November 2017. A more recent publication on the question was located: Muddugangadhar 2015, PubMed: 26435609. This systematic review with meta-analysis of 63 prospective and retrospective cohort studies showed similar results; it showed that single implant-supported crowns have overall higher 5-year survival rates than implant-supported FPDs. However, this more recent research included implant tooth-supported prostheses as well.
