The reproduction of natural tooth color using porcelain restorations is quite cumbersome, for it is difficult to select, communicate, reproduce, and evaluate color objectively. The present process of color reproduction lacks precision and is primarily dependent on the individual efforts and abilities of the dentist and ceramist. The computer color-matching system, aided by a spectrophotometer and computer, can be an excellent method for reproducing specific colors of various objects. This paper reports application of the system to reproduce various opaque colors used for metal ceramic restorations.
