  • 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.

  • Evidence Quality Rating:
