Metal-free tooth-supported FDPs (pressed veneering ceramic) vs Metal-free tooth-supported FDPs (layered veneering ceramic)

Aesthetics · Adults (18 years or older) needing a three-unit tooth-supported fixed dental prosthesis
1 finding from 1 review
  • No comparative data were presented with regard to aesthetics. Aesthetics evaluated by the patient was reported dichotomously (yes/no) in the trial but no between-group estimate was presented.

Metal-free tooth-supported FDPs (pressed veneering ceramic) vs Metal-free tooth-supported FDPs (layered veneering ceramic)

Periodontal/peri-implant status (secondary outcomes) · Adults (18 years or older) needing a three-unit tooth-supported fixed dental prosthesis
1 finding from 1 review
  • No comparative data were presented for the pre-specified secondary outcomes. The trial analyzed and reported plaque index, bleeding on probing and pocket probing depth but no between-group estimate was presented in the…

Metal-free tooth-supported FDPs (pressed veneering ceramic) vs Metal-free tooth-supported FDPs (layered veneering ceramic)

Bridge failure · Adults (18 years or older) needing a three-unit tooth-supported fixed dental prosthesis

Metal-free tooth-supported FDPs (pressed veneering ceramic) vs Metal-free tooth-supported FDPs (layered veneering ceramic)

Bridge complications · Adults (18 years or older) needing a three-unit tooth-supported fixed dental prosthesis

It is very uncertain whether metal-free tooth-supported FDPs (pressed veneering ceramic) changes bridge complications compared with metal-free tooth-supported FDPs (layered veneering ceramic) (very low certainty).

Ceramic inlays (all types) vs Composite resin inlay

Outcome not reported · Adults who require restorative treatment in posterior teeth

The review found no eligible studies for this question.

1 finding from 1 review
  • Ceramic inlays for restoring posterior teeth 2003 · Cochrane All outcomes
    One randomised controlled trial (Gladys 1995) compared ceramic and resin composite inlays over 3 years, but it was excluded because the study design (parallel-group or split-mouth) was not clearly described; no…

Ceramic inlays (all types) vs Gold inlay

Aesthetic satisfaction (colour match) · Adults who require restorative treatment in posterior teeth

The review found no eligible studies for this question.

1 finding from 1 review
