Effect of immediate and delayed dentin sealing on the fracture strength, failure type and Weilbull characteristics of lithiumdisilicate laminate veneers

Nov 23, 2017 by in Dental Materials Comments Off on Effect of immediate and delayed dentin sealing on the fracture strength, failure type and Weilbull characteristics of lithiumdisilicate laminate veneers

Abstract Objectives Adhesion on dentin is less reliable than on enamel, which could affect the durability of laminate veneers (LV). Immediate dentin sealing (IDS) is suggested instead of delayed dentin…

Probing the dual function of a novel tertiary amine compound in dentin adhesive formulations

Nov 23, 2017 by in Dental Materials Comments Off on Probing the dual function of a novel tertiary amine compound in dentin adhesive formulations

Abstract Objectives A novel tertiary amine compound containing three methacrylate-urethane groups was synthesized for application in dentin adhesives. The synthesis, photopolymerization kinetics, and leaching were examined in an earlier study…

Complexity of the relationships between the sintering-temperature-dependent grain size, airborne-particle abrasion, ageing and strength of 3Y-TZP ceramics

Nov 23, 2017 by in Dental Materials Comments Off on Complexity of the relationships between the sintering-temperature-dependent grain size, airborne-particle abrasion, ageing and strength of 3Y-TZP ceramics

Highlights • Sintering temperature affects the grain size, transformability and strength of 3Y-TZP. • The high-temperature-sintered, coarse-grained 3Y-TZP experiences a higher surface strengthening than the low-temperature-sintered, fine-grained 3Y-TZP. • Ageing…
