Shear bond strength to feldspathic porcelain of two luting cements in combination with three surface treatments

The effect of five kinds of surface treatment agents on the bond strength to various ceramics with thermocycle aging

“…Statistical analysis of the failure modes was performed using the Kruskal-Wallis rank test. For this, each failure mode was given a score from 1 to 5 prior to statistical analysis 23,25) . A score of 1 was given for interfacial failure, a score of 2 for mixed failure with interface and cement, 3 for mixed failure with ceramic material and interface, 4 for cohesive failure within cement; and 5 for cohesive failure within ceramic material.…”

Influence of Different Ceramics on Resin Cement Knoop Hardness Number

“…Dual-cure adhesive luting cements have shown higher bond strength values than chemically-activated adhesive luting cements, perhaps because the latter have fewer initiators and/or more inhibitors of polymerization to extend the working time. 6 Furthermore, the degree of conversion of cement affects hardness, wear resistance, water absorption, residual monomer and biocompatibility of adhesive luting resin cements and these properties affect the survival of the restoration. 7 Dual cure resin cements have the advantage of both chemical-cure and light-cure materials.…”

Porcelain laminate veneer restorations bonded with a three-liquid silane bonding agent and a dual-activated luting composite

“…The use of a methacrylate-based silane monomer is essential for bonding feldspathic porcelain. Based on previous reports evaluating in vitro bond strength (9,(15)(16)(17), the three-liquid Clearfil Porcelain Bond material was selected for seating the restorations. The advantages of the Clearfil three-liquid system are that the acidic MDP monomer is effective for bonding tooth structure and for activating silane couplers, and the composition is selfpolymerizing.…”

“…8-12). After try-in of the restoration, the surface to be bonded was etched with 5% hydrofluoric acid (HF-Gel, GC Corp.) for 60 seconds (4), washed under tap water, ultrasonically cleaned in methanol, dried with an air syringe, and primed with a three-liquid ceramic bonding agent (Clearfil Porcelain Bond, Kuraray Medical Inc.) (7,9) (Figs. 13-18).…”

“…Application of a methacrylate-based silane monomer enhanced the bonding between acrylic resin and feldspathic porcelain materials (6)(7)(8)(9). The improvement in bonding of acrylic resin to enamel by phosphoric acid etching was reported more than 50 years ago (10).…”
