Abstract

Cognitive Design of Crowns and Bridges

M. van der Zel

  • Three anterior crowns were produced in Vita A1, A2 and A3 color, with the Primero process and the substructure library model. Three different cervix colored zirconia substructures in zA1, zA2, zA3 were used with the same transparent enamel porcelain. After production the crowns were evaluated for any anomalies, like bubbles or whiteness. The color was measured with a Coloreye® spectrophotometer (Olympus, Japan). The overall color and appearance was compared with the Vita Classic color guide for matching.
