Abstract:
Objective To study the effect of two kinds of silane coupling agent on bond strength of resin-ceramic adhesive.Methods Four hundred and thirty-two ceramic samples were divided into 9 groups (48 per group ),and in each group the ceramic surface was treated with r-methacryloxypropyletrimethoxysilane(MPTS) (50 g/L) in 99％ ethanol (Primer A) and the mixture of hydrochloric acid (0.10 mol/L),phosphoric acid (0.05 mol/L) and acetic acid (0.01 mol/L) in 99％ ethanol with the same volume (Primer B).Then the treated ceramic was bonded with resin cement (Link Max).The shear bond strength was tested after 5000 and 10 000 thermo-cycles and standing for 24 h.Results The highest shear bond strengths [ ( 19.5 ± 3.7 ) MPa、( 15.7 ± 3.0) MPa and ( 14.6 ± 3.0) MPa] of the specimens were obtained with 0.05 mol/L hydrochloric acid.At acid solution of 0.10 mol/L,the specimens using hydrochloric acid [ ( 10.6 ±3.5) MPa] and phosphoric acid [ (9.5 ±2.7) MPa] showed remarkably higher strength than that using acetic acid [(6.3 ±2.5) MPa,P＜0.05] after 10 000 thermo-cycles.When the concentration of acid solution was 0.05 mol/L,the shear bond strength of specimens from hydrochloric acid [(14.6±3.0) MPa] was significantly higher than that using phosphoric acid [(6.3 ± 1.9) MPa] and acetic acid [ (4.7 + 1.8) MPa,P ＜0.05].When the concentration of acid solution reached 0.01 mol/L,the specimens using hydrochloric acid exhibited a dramatically increase in shear strength[ ( 12.7 +3.2) MPa] compared with that using phosphoric acid [( 2.3 ± 1.2 ) MPa,P ＜ 0.05 ] and acetic acid [(1.5 +1.2) MPa,P＜0.05].Condusions The maximum adhesive bond strength with highest durability was obtained using hydrochloric acid of 0.05 mol/L hydrolysis catalysts to treat siline couple agent.
