Abstract
This study aims to evaluate the resistance to physiological wear of the characterization layer applied on hybrid ceramics with different surface treatments, as a function of the zirconia antagonist. One hundred and sixty (14 mm diameter, 1.2 mm thick) discs of hybrid polymer ceramics (Vita Enamic, Vita Zhanfabrick, Bad Säckingen, Germany) will be made, which will be polished with silicon …
