Abstract
Chipping of veneer porcelain is a recurrent problem in all-ceramic systems with yttria-stabilized tetragonal zirconia (Y-TZP). In order to eliminate the necessity of porcelain veneering, high translucency Y-TZP has been introduced, which as well as lithium disilicate, were developed for monolithic indication. However, the mechanical behavior of these new materials under fatigue and the mi…
