Brief Summary

The aim of the present study is to assess the clinical performance (patient satisfaction, fracture, shade matching, Marginal adaptation and sensitivity) of laminate veneers made with celtra duo press ceramic and IPS e.max press ceramic with incisal wrap design.

Detailed Description

Ceramic materials are widely used for esthetic restorations because of their physical and optical properties that enhance patient satisfaction to dental restorations. several ceramic materials are currently available, including the lithium-reinforced glass ceramic like e.max press, which stands out for its excellent esthetic appearance and mechanical properties.also ZLS (zirconia-reinforced lithium silicate) are a function of its unique micro structure (500-700 nm in size, correspond exactly to the wavelength range of natural daylight). The presence of 10% zirconia in the glass phase in atomically dissolved form provides high strength and ensures safe and long-lasting restorations .The result is a large number of very fine-grained lithium silicate crystals, whose high glass content give the material its excellent light-optical and mechanical properties.

Translucency, opalescence, fluorescence and the chameleon effect all benefit, with high edge stability and excellent polishability being an added plus.3 Despite the recent introduction of improved ceramic materials, patient satisfaction with restoration contour,symmetry,margins and shade matching natural teeth with ceramic restorations is still one of the major challenges in clinical practice. The determination and interpretation of natural tooth color involve the selection and reproduction of ceramic shade and choice of restorative material. These factors have had a major influence on the final color of restorative treatments. Color-measuring instruments assist in shade analysis, thus minimizing the subjective variables of this process. Color readings allow improved determination of the restoration shade and better communication with the dental laboratory.4The influences of underlying substrate,8-9 luting agent,ceramic thickness and translucency, and restoration type14 on the color variation of ceramic restorations have been investigated in in vitro studies. Thus, the purpose of this study was to evaluate clinical performance of celtra duo press ceramic and IPS e.max press ceramic laminate veneers including patient satisfaction, fracture, shad matching, marginal adaptation and sensitivity.
