Effect of light-curing techniques and preheated composite types as luting agents on lithium disilicate bond strength

Majalah Kedokteran Gigi Indonesia
he bond strength between lithium disilicate veneers and tooth structure depends on factors such as curing technique and luting agent. Preheated composite resins have been proposed as alternative luting agents due to their favorable mechanical and ...

Influence of Different Multilayer Zirconia Materials on the In Vitro Load‐Bearing Capacity of Resin‐Bonded Fixed Partial Dentures in the Posterior Region

Journal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Objective Comparison of the load‐bearing capacity and failure pattern of posterior resin‐bonded fixed partial dentures (RBFPDs) differing in retainer design, zirconia material, and vertical nesting position. Materials and Methods RBFPDs replacing a maxillary first molar were fabricated with 2 retainer designs (inlay‐retained, IR; wing‐retained,

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

Influence of Universal Adhesives With or Without Silane Compared to One‐Step and Two‐Step Silane Agents on Bond Strength to Lithium Disilicate

Journal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Objective To evaluate the microshear bond strength (μSBS) to lithium disilicate achieved with universal adhesives (with and without silane) compared with one‐step and two‐step silanes, immediately (IM) and after thermocycling (TC). Chemical interaction (CI) was also assessed.
