Abstract
In the presence of body fluid, polycrystalline tetragonal zirconia (3Y-TZP) presents a transformation from the tetragonal to the monoclinic crystalline phase, with a volumetric expansion (4-5%) with an increase in tension, which can generate microcracks from the loading process that will cause the material fracture, this effect was called "Low-Temperature Hydrothermal Degradation" (LTD), …
