The purpose of this study is to assess the aesthetic outcome of glass ceramic restorations of various thicknesses cemented to composite resin substrates of different shades with multiple cements. 120 samples of IPS e.max® CAD (HT) (Ivoclar Vivadent, Schaan, Liechtenstein) lithium disilicate ceramic and 120 samples of VitaBlocs® Mark II (VITA Zahnfabrik, Bad Säckingen, Germany) feldspathic ceramic in colour A1 were obtained. The samples were cut with a thickness of 0,5mm and 0,8mm. For the simulation of the substrate, 240 samples of FiltekTM Supreme XTE Universal Restorative Body (3M ESPE, Minnesota, USA) composite resin in colours A2 and A3 were produced with a thickness of 1mm. All samples were polished. After surface treatment, the ceramic samples were cemented to the composite resin samples, according to the groups formed, initially with glycerine and subsequently with RelyXTM Veneer Cement System (3M ESPE, Minnesota, USA) in the Translucent (TR) and White Opaque (WO) shades, and...
