Once the desired vertical dimension is achieved, the final res- torations of the upper arch included ceramic bridges (
zirco- nium) in teeth 17-15-13 and all ceramic crowns (Emax.press) in teeth 12-17.
Optical Characteristics: yttria-stabilized zirco- nia (ySZ) shows high refractive index (2.1 to 2.2) low absorption coefficient and high opacity in the visible and infrared spectrum.
