Abstract
The objectives of this project are: (1) To compare the stress corrosion suscebility exponent (n), obtained by cyclic fatigue and dynamic fatigue for two dental ceramics: Yttria partially stabilized tetragonal zirconia polycrystal (Y-TZP) and a feldspathic porcelain (VM). (2) To verify the existence of R curve behavior for the studied materials and correlate these results with the n values…
