Method for direct multi-shading of natural color in full ceramic restoration, involves forming glaze on full ceramic restoration with multi-shading colors by covering full ceramic restoration with glaze material

摘要

The method involves forming a full ceramic restoration from a ceramic green body mold (S100). Required multi-shading colors are applied (S120) on the restoration by a computer-aided process. The full ceramic restoration is formed with the shadow colors for sintering the full ceramic restoration green body and the shading color dyes (S130). A glaze is formed on the full ceramic restoration with the shading colors by covering the full ceramic restoration with a glaze material in a high temperature oven for sintering the glaze material (S150). Pigment is applied on the ceramic green body. The pigment is made of artificial caramel, edible pigment, azo pigment and non-azo pigment i.e. phthalocyanine.
