Metal-free single crowns (full-contour zirconia) vs Cast gold (conventional metal) single crowns

Crown complications · Adults (18 years or older) needing a single crown in the molar or premolar region

It is very uncertain whether metal-free single crowns (full-contour zirconia) changes crown complications compared with cast gold (conventional metal) single crowns (very low certainty).
