“…The results of the present study also showed a significant difference in translucency between IPS e.max CAD and Katana zirconia UTML after cementation and after aging. This finding is supported by previous studies 9,10,14 . The least observed change in translucency was found in Katana zirconia.…”

To investigate the effect of resin cements on the color stability and translucency of ceramic laminate veneers used for diastema closure. Sixty resin abutments were prepared for ceramic laminate veneers and divided into six groups according to the ceramic type (lithium disilicate, zirconia-reinforced lithium silicate, and translucent zirconia) and the cement type (Variolink Esthetic LC and RelyX Veneer). Color coordinates and translucency were analyzed after cementation and after soaking in the coffee solution. Differences in color and translucency were estimated, and results were statistically assessed (α = 0.05). Ceramic materials showed a significant impact on color changes after soaking in coffee within Variolink Esthetic groups. Translucent zirconia showed the highest color change, followed by zirconia reinforced lithium silicate and lithium disilicate. Ceramic materials showed a significant impact among the RelyX Veneer groups. A significant interaction in color changes was found between ceramic types and cement types after cementation, and after soaking in coffee was found. All groups showed a clinically acceptable difference in translucency parameters after soaking in coffee. The resin cement affects the color and translucency of ceramic laminate veneers used for diastema closure, and ceramic laminate veneers bonded with Variolink Esthetic LC resin cement are more translucent, while ceramic laminate veneers bonded with RelyX Veneer resin are more resistant to coffee staining. The lithium disilicate laminate veneer is more resistant to coffee staining than zirconia reinforced lithium silicate and translucent zirconia laminate veneers used for diastema closure.

“…Another possibility is pressing fluorapatite glass-ceramic ingots onto CAD/CAM milled zirconia frameworks: IPS e.max ZirPress (Ivoclar Vivadent, Schaan, Liechtenstein), which allows pressing onto IPS e.max ZirCAD (Ivoclar Vivadent, Schaan, Liechtenstein), Zenostar Wieland Dental (Pforzheim, Germany), and other zirconia frameworks with a CTE of 10.5-11.0. The press-on technique is indicated for multi-unit bridges and crowns and implant superstructures [38][39][40].…”

Human teeth play an important role in facial aesthetics. The modern society trends for more and more demanding aesthetics strongly reflect in teeth appearance. Perfect shaped, aligned, and white teeth are considered the business card of an appealing smile. Fixed prosthetics not only aim to restore the lost function of human teeth but also their aesthetics. The ideal in this matter is to provide an indirect restoration that perfectly matches the neighboring teeth or aims to improve the overall appearance of the patient’s teeth, depending on the situation. However, the choice of aesthetic materials and technologies has experienced a significant development in recent years. By far, dental ceramics are the state-of-the-art material when a high-quality indirect fixed prosthetic restoration is the goal. This chapter will provide information on this class of materials and their indications in fixed prosthodontics, focusing on novel manufacturing technologies, as well.

Objective To investigate the effect of resin cements on color stability and translucency of ceramic laminate veneer materials used for diastema closure. Materials and Methods Sixty resin abutments were prepared for ceramic veneers and divided into six groups according to the ceramic type (lithium disilicate, zirconia reinforced lithium silicate, and translucent zirconia) and cement type (Variolink Esthetic LC and RelyX Veneer). The color coordinates and translucency were analyzed after cementation and after immersion in coffee solution. The differences in color and translucency were estimated, and the results were statistically assessed (α = .05). Results Ceramic materials showed a significant impact on the color changes after coffee immersion within Variolink Esthetic groups. Zirconia showed the highest color change, followed by zirconia reinforced lithium silicate and lithium disilicate. The ceramic materials showed a significant impact among the RelyX Veneer groups. A significant interaction in color changes between ceramic type and cement type after cementation, and after coffee immersion were found. All groups showed a clinically acceptable difference in translucency parameters after coffee immersion. Conclusions Cement selection is important for the color stability and translucency of ceramic laminate veneers after coffee immersion. Lithium disilicate veneer is more resistant to coffee staining than zirconia reinforced lithium silicate and zirconia veneers. Ceramic laminate veneers cemented with resin cement contain benzoyl germanium compounds (Variolink Esthetic) are more translucency. However, ceramic laminate veneers cemented using resin cement contain iodonium salts (RelyX Veneer) are more resistant to coffee immersion.
