Análise da estabilidade de cor de facetas laminadas confeccionadas em cad-cam : estudo observacional de coorte

Abstract

The improvement demand for aesthetic restorations, in association with the evolution of techniques and materials, made it possible to manufacture restorations of significant reduced thickness. The introduction of CAD-CAM technology made it possible to perform precise restorations and reduce the clinical execution time. It´s known that different factors, including surface texture, opalescence, translucency, substrate color, cement color, thickness of restorative material affect the final color of restorations. However, the final color of the restoration remains the direct responsibility of the dentist, where a visual assessment of color can cause errors, while an instrumental color measurement has accurate readings. Therefore, the aim of this clinical study is to investigate the color stability of veneers manufactures with different CAD-CAM materials.
