Metal-free FDPs (zirconia ceramic) vs Metal-ceramic FDPs

Periodontal/peri-implant status (secondary outcomes) · Adults (18 years or older) needing a three-unit fixed dental prosthesis (FDP)

The review found no eligible studies for this question.

Metal-free cantilevered FDPs (feldspathic-veneered zirconia) vs Metal-ceramic cantilevered FDPs

Cantilevered bridge complications · Adults (18 years or older) needing replacement of one premolar or incisor with a cantilevered fixed dental prosthesis

It is very uncertain whether metal-free cantilevered FDPs (feldspathic-veneered zirconia) changes cantilevered bridge complications compared with metal-ceramic cantilevered FDPs (very low certainty).

Metal-free FDPs (zirconia ceramic) vs Metal-ceramic FDPs

Patient satisfaction (measured by patient satisfaction or aesthetic scales) · Adults (18 years or older) needing a three-unit fixed dental prosthesis (FDP)

It is very uncertain whether metal-free FDPs (zirconia ceramic) changes aesthetic evaluation (patient aesthetic satisfaction changes) compared with metal-ceramic FDPs (very low certainty).

Metal-free cantilevered FDPs (feldspathic-veneered zirconia) vs Metal-ceramic cantilevered FDPs

Aesthetics evaluated by the patient · Adults (18 years or older) needing replacement of one premolar or incisor with a cantilevered fixed dental prosthesis

It is very uncertain whether metal-free cantilevered FDPs (feldspathic-veneered zirconia) changes aesthetic evaluation (patient VAS) compared with metal-ceramic cantilevered FDPs (very low certainty).
