Flexural strength and microstructure of two lithium disilicate glass ceramics for CAD/CAM restoration in the dental clinic
OBJECTIVES There has been a growing interest in glass ceramic systems with good esthetics, high fracture resistance and bonding durability, and simplified fabrication techniques using CAD/CAM. The aim of this study is to compare flexural strength before and after heat treatment of two lithium disilicate CAD/CAM blocks, IPS e.max CAD (Ivoclar Vivadent) and Rosetta SM (Hass), and to observe their...

متن کاملEffect of Heat-Pressing Temperature and Holding Time on the Microstructure and Flexural Strength of Lithium Disilicate Glass-Ceramics
The present study aimed to evaluate the influence of various heat-pressing procedures (different holding time and heat pressing temperature) on the microstructure and flexural strength of lithium disilicate glass ceramic. An experimental lithium silicate glass ceramic (ELDC) was prepared from the SiO2-Li2O-K2O-Al2O3-ZrO2-P2O5 system and heat-pressed following different procedures by varying tem...
متن کاملEffects of Different Polishing Protocols on Lithium Disilicate Ceramics.
The aim of this study was to evaluate the effect of different polishing protocols on surface roughness and morphology of lithium disilicate ceramics (IPS e.max CAD). Fifty ceramic bars (2.0x3.0x2.5 mm) were produced and randomly divided into five groups (n=10), according to surface treatments: C: Control; Cer: Ceramaster (60 s); CW: cloth wheel with large-grit diamond (30 s) + cloth wheel with ...
متن کاملA Comparison of Tensile Bond Strength between Low Translucency and High Translucency Lithium Disilicate Ceramics Using Two Different Resin Cements
Objectives: To compare two different dual-curing resins cement interfaces between low translucency and high translucency lithium disilicate glass-ceramics in vitro. M~aterials and Methods: ISO 11405 was modeled by using a standardized dumb-bell test to compare the tensile bond strength of two different resin cement interfaces ofa low translucency lithium disilicate ceramic to a high translucenc...
