The use of monolithic lithium disilicate for posterior screw-retained implant crowns

, 2017
Lithium disilicate is typically used for fabricating prosthetic crowns to be cemented on teeth or implant abutments. However, its use for producing screw-retained implant crowns has been less commonly described.

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

Translucency Changes of Ceramic Veneers After Aging When Cemented on Substrates With Different Saturation: Effect of Ceramic Translucency and Resin Cement Shade

Journal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Objective To evaluate the effect of ceramic translucency and resin cement shade on the translucency alteration after aging over different substrates. Methods Sixty specimens were divided into 12 groups (n = 5) composed of lithium disilicate (IPS e.max CAD, Ivoclar Vivadent) in three translucencies (HT, MT, LT).

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 ...

Partial Mock‐Up–Guided Rehabilitation of Severe Tooth Wear: A Clinical Technique

Journal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Objective This article describes a staged temporary occlusal protocol for selected patients with severe tooth wear and altered mandibular closure, illustrated through a clinical case. Clinical Considerations Advanced tooth wear may be associated with a protrusive mandibular posture, reduced posterior support, and incisal‐dominant function.
