Pressure‐driven homogenization of lithium disilicate glasses

Journal of the American Ceramic Society
Abstract Lithium disilicate glasses and glass–ceramics are good potential candidates for biomedical applications, solid‐state batteries, and serve as models of nucleation and crystal growth. Moreover, these glasses exhibit a phase separation that influences their nucleation and crystallization behavior. The atomistic mechanisms of the

Wear behavior of pressable lithium disilicate glass ceramic [PDF]

Journal of Biomedical Materials Research Part B: Applied Biomaterials, 2015
AbstractThis article reports effects of surface preparation and contact loads on abrasive wear properties of highly aesthetic and high‐strength pressable lithium disilicate glass‐ceramics (LDGC). Abrasive wear testing was performed using a pin‐on‐disk device in which LDGC disks prepared with different surface finishes were against alumina pins at ...

Marginal gap of printed, milled, and heat‐pressed two‐piece polyetheretherketone abutments before and after thermal cycling, and their pull‐off bond strength after thermal cycling

Journal of Prosthodontics, EarlyView.
Abstract Purpose To evaluate the marginal gap of two‐piece polyetheretherketone (PEEK) abutments fabricated with different methods, before and after thermal cycling, while also focusing on their pull‐off bond strength. Materials and Methods A two‐piece abutment was virtually designed after digitizing a titanium‐base (Ti‐base) abutment.

Color Stability of Three Ceramics After Thermocycling in Coffee, Black Tea, Cola, and Water: An In Vitro Study

International Journal of Dentistry
Conclusion: The color stability of monolithic zirconia was more than lithium disilicate in coffee, black tea, cola, and water solutions. The color of lithium disilicate was more stable than zirconia-reinforced lithium silicate in all staining solutions ...
