Abstract

Objectives To investigate the effects of polishing systems on the roughness, gloss and color of two zirconia materials as a function of the rotational speed and number of polishing movements. Materials and methods Specimens (n = 8/group) from 4Y-TZP and 5Y-TZP were milled, diamond grinded and polished. The intraoral polishing varied in the number of polishing steps, the grain size and the ...
