Interfacial fracture toughness of different resin cements bonded to a lithium disilicate glass ceramic

Adhesive/silane application effects on bond strength durability to a lithium disilicate ceramic

“…The other two layers formed, holds no value for the bond strength . The external and intermediate layers have loose oligomers, resulting in a weak siloxane bond and can be removed using organic solvent or water; the most external layer and the intermediate can also be removed using hot water …”

Microshear Bond Strength of Resin Cements to Lithium Disilicate Substrates as a Function of Surface Preparation

“…These findings are in agreement with those of other studies that found an increase in bond strength after HF etching, even though the manufacturer's recommendations were not strictly followed, specifically as they regard longer etching times and higher HF concentrations. [24][25][26] However, the 20-second acid-etching time and 4.8% HF concentration (as recommended by the LD manufacturer) were used in the present study because an increase of LD acid-etching time reduces the ceramic flexural strength and modifies the surface roughness. 27 When a self-adhesive resin cement was used with LD our results suggest that HF and MBP (HFMonobond Plus-RelyX Unicem 2) should be applied on the LD intaglio surface, as demonstrated by the significant increase in mean lSBS.…”

Evaluation of Adhesive Bonding of Lithium Disilicate Ceramic Material with Duel Cured Resin Luting Agents

“…It has been proved that application of resin-based luting and priming agents containing the adhesive monomer MDP provide better bond strength to zirconia than do other systems [4]. Tabassom Hooshmand et al, concluded that the interfacial fracture toughness for the lithium disilicate glass ceramic system was affected by the surface treatment and the type of luting agent [5].…”
