Abstract

3 mol% yttria-stabilized tetragonal zirconia polycrystal (3Y-TZP) ceramics are promising restorative materials being extensively used for fabricating dental prosthodontics. The invited talk aims to report a novel method of surface texturing to improve the serving properties of 3Y-TZP ceramics. Different types of surface textures, including micro-honeycombs, micro-composite grids, and micro-grooves, were fabricated onto the zirconia specimens. The effects of different microtextures on surface behaviors, including wettability, bacteria adhesion, and wear behavior, of 3Y-TZP ceramics were rigorously studied. The results obtained can provide technical guidance for the design and application of microtextures in the restorative dental fields.
