How do we make your sameday porcelain dental crown, overlay or veneer? When we make you a sameday porcelain restoration we create the crown, overlay or veneer in our E4D Computer CAD/CAM design centre - Same process as Cerec. Here in Milford on Auckland's North Shore we can create beautiful, strong emax porcelain restorations that blend into your smile. Emax porcelain is incredibly strong - over 3 times stronger than the porcelains we used to use. If your dental crown is broken or chipped we can remove it & replace it with a much stronger biocompatible emax crown. All porcelain restorations refract light naturally which means no more black lines where the crown meets your tooth. This video clip gives you an idea of how a restoration is designed...........
