Stepwise stress testing of different CAD-CAM lithium disilicate veneer application methods applied to lithium disilicate substructures

The Journal of Prosthetic Dentistry, 2022
Whether a computer-aided design and computer-aided manufacture (CAD-CAM) fabricated high-translucency lithium disilicate veneer on a lithium disilicate substructure would increase the strength of the restoration compared with a traditional feldspathic porcelain veneer is unclear.The purpose of this in vitro study was to evaluate the effect of different

The effects of ultrasonic cavitation on the dissolution of lithium disilicate glass

Scientific Reports, 2022
AbstractThere has been little research conducted on how ultrasonic cavitation may affect glass dissolution. The focus of this study was to examine how the mechanisms and kinetics of glass dissolution may change in a system that included ultrasonication. Experiments were conducted on lithium disilicate glass in deionized water at 50 °C between 1 and 7.5

Modulation of Lithium Disilicate Translucency through Heat Treatment [PDF]

Materials, 2021
The aim of this study was to present a control method for modulating the translucency of lithium disilicate ceramics through thermal refinement. Identical lithium disilicate blocks were thermally refined using four different heat treatment schedules, and the microstructure, translucency, and flexural strength of the ceramics were investigated in detail
