Clinical and laboratory surface finishing procedures for zirconia on opposing human enamel wear: A laboratory study.

Aim: To investigate the effect of laboratory and clinical finishing procedures for zirconia on antagonistic enamel wear.

Materials And Methods: Forty-eight yttria-tetragonal partially stabilised zirconia (Y-TZP) specimens were prepared and divided into four groups according to their surface preparation: laboratory polished (LP); laboratory polished and glazed (G); clinically adjusted (CA); and clinically adjusted and repolished (CAR). Enamel opposing enamel was used as a control.
