Metal-free implant-supported single crowns (zirconia veneered with feldspathic ceramic) vs Metal-ceramic implant-supported single crowns

Patient satisfaction (measured by patient satisfaction or aesthetic scales) · Adults (18 years or older) with one missing tooth in the aesthetic zone needing an implant-supported single crown

It is very uncertain whether metal-free implant-supported single crowns (zirconia veneered with… changes aesthetic evaluation (patient satisfaction VAS) compared with metal-ceramic implant-supported single crowns (very low certainty).
