Abstract

Porcelain laminate veneer crown is an excellent system to improve the color of a discolored tooth in the anterior region having an occlusal contact.<BR>Since musking porcelain has opacity for hiding the discolored tooth, it was difficult to give a high translucency to the laminate crowns by conventional methods. The purpose of this study was to produce the natural color and excellent appearance of laminate crowns using the Computer Color Matching (CCM) system to compensate opacity of musking porcelain. CCM sample is composed of three layers: surface layer, musking layer, discolored layer. CCM formulation for musking porcelain was calculated to give optimum color to the CCM sample. The formulation indicated the mixing ratio of the translucent (TL) and three kinds of opaques selected from 8 (white, yellow, blue, pink, gray, A1, A2, A3). In accordance with the CCM formulation, musking porcelain was baked and the CCM porcelain samples (underlaying layer + musking porcelain layer: 0.3mm+surface layer: 0.3mm) was made.<BR>Compared to the target color and CCM sample, both reflectance curves are very similar and the color differences dE ranged from 2.0 to 4.0. Furtheremore, CCM sample showed the color to be indistinguishable from the target color by the naked eye.
