This study aimed to investigate the effects of optical properties lithium disilicate glass ceramics and light-curing protocols (LCP) on curing performance light-cured resin cement. Lithium glass-ceramics with different were sectioned produce ceramic specimens 0.8 mm thickness. Irradiance through was measured by a radiometer. Light transmittance assessed using UV/Vis spectrophotometer. The cemen...

PURPOSE The goal of this study was to evaluate the fracture resistances of various monolithic crowns fabricated by computer-aided design and computer-aided manufacturing (CAD/CAM) with different thickness. MATERIALS AND METHODS Test dies were fabricated as mandibular molar forms with occlusal reductions using CAD/CAM. With different occlusal thickness (1.0 or 1.5 mm), a polymer-infiltrated ce...

Recommendations to obtain the best bonding silica-based ceramics are prepare its surface by hydrofluoric-acid HF etching and regular application of a silane. This study investigated how HF-etching following ultrasonic water bath cleaning (recommended protocol improve with composite resin), modifies chemistry lithium disilicate glass-ceramic impacts chemical Lithium discs (IPS Emax Press, Ivocla...

The aim was to evaluate the adaptation of CAD/CAM occlusal veneer with different cement space settings using micro CT scan. Three groups IPS e.max-CAD lithium disilicate veneers (30, 40, and 50 µm) were produced. A circle 20 diameters centered at center same image position every scanned specimen scan measure four locations [Occlusal (OCG), axial (AXG), Marginal (MAG), absolute marginal discrepa...
