Objectives: Tooth-to-implant–connected prostheses have been described as a possible treatment option for patients with long-span edentulous situations that were not conducive for placement of an adequate number of supporting implants. In this comprehensive overview of systematic reviews, the incidence of complications and the long-term survival rates of tooth-to-implant–supported fixed partial dentures (FPDs) were evaluated to determine whether it is a viable treatment.

Materials and Methods: A systematic search of 5 electronic databases was conducted for systematic reviews and meta-analyses of tooth-to-implant–supported FPDs up to January 2017. The articles were AMSTAR rated for methodological quality, and low-quality articles were eliminated.

Results: The initial search yielded 369 reviews in PubMed, 248 in Web of Science, 49 in EMBASE, 63 in Cochrane Library, and 27 in Google Scholar. After removal of duplicates and after full-text analysis, 5 were selected for the overview.

Conclusions: Within the limitations of this overview, it was concluded that (1) the 10-year survival rates for tooth-to-implant FPDs were lower than the 5-year survival rates, (2) the tooth-to-implant FPDs' survival was lower than the individual abutment tooth or implant supporting it, (3) the biological and technical complications were more at 10 years compared with 5 years, and (4) the intrusion of the abutment teeth was more in the nonrigid connection FPDs than the rigid connection FPDs. Therefore, tooth-to-implant FPDs are a viable option but should be considered secondary to other available options with higher long-term survival rates and lower complications.
