Abstract
The most used material for implants is titanium and there are ceramic implants of zirconia partially stabilized with yttria (3Y-TZP) on the market. However, in the presence of liquid (body fluid), 3Y-TZP presents a transition from the tetragonal to the monoclinic crystalline phase, with a volume expansion of 4-5%, generating microcracks that with the loading process may result in fracture…
