This formation produces a considerable increase in flexural strength higher than 200 MPa. The material approaches the prerequisites of an ideal all ceramic restorative material. Surface smoothness, extreme accurate marginal fits and biological compatibility, plus its higher strength, make Empress ideal for crowns, inlays, and veneers.
Empress is a pressure-molded ceramic that was prepared from a wax pattern.
After the pattern is invested and burned out in a two stage oven, molten ceramic is pressed into the mold. The restoration can either be enhanced by surface characterization or layered to achieve the maximum aesthetics possible. It is important to note that tooth preparation for ceramic crowns is extremely important. Proper tooth preparation optimizes the material's ability to achieve maximum strength and accuracy of fit.
