Limited evidence that cantilevers are associated with slightly lower survival rates of implant-supported fixed partial dentures

Carlos Flores-Mir DDS, DSc, FRCD(C); Heeje Lee D.D.S.; Alika Yu DDS .


Systematic Review Conclusion

Implant-supported fixed partial dentures (FPDs) with cantilevers have a higher incidence of technical complications and lower five-year survival rates compared with those for FPDs without cantilevers.

Critical Summary Assessment

The authors included only three studies (totaling 175 patients) of limited methodological quality, which weakened their conclusions.
