What is Optical effect of resin cement, abutment material, and ceramic thickness on the final shade of CAD-CAM ceramic restorations about?

## Statement of problem: High-translucency ceramics can be influenced by the underlying structure, altering the restoration shade. how this affects color matching is unclear. ## Purpose: The purpose of this in vitro study was to investigate the optical effects of cement shade, ceramic type, ceramic thickness, and abutment material on the final color of computer-aided design and computer-aided manufacturing (cad-cam) ceramic restorations. ## Material and methods: Two shades of resin cement (yellow, translucent), 3 types of background (titanium, white zirconia, yellow zirconia), and 3 types of high-translucent ceramic (each type shade a1 and a3) were used in this study. for the experimental groups, a total of 72 ceramic specimens were produced across 4 groups based on ceramic thickness (1.0 mm, 1.5 mm, and 2.0 mm). for the control groups, each ceramic type and shade was prepared at a thickness of 4 mm. a total of 8 resin cement specimens were produced in 4 groups based on shade by using a plastic mold (12×12×0.2 mm). to demonstrate the effect of implant abutment materials, 3 types of background were fabricated with a thickness of 2 mm. for the experimental groups, 3 specimens (cerami
