Abstract

The purpose of the current study was to investigate the effect of surface preparations on bond strength to heat-pressed ceramic material (IPS Empress 2, E2) of glass-ionomer luting materials. The E2 specimens were employed as the adherend materials and E2 surface treatments for mechanical retention were; 1) etching with phosphoric acid, 2) etching with hydrofluoric acid (HF) and 3) air-abrasion with alumina. Surface treatments for chemical retention were silane treatments. Two conventional glass-ionomer materials and two resinmodified glass-ionomer materials were used as the luting agents. Shear bond strengths were determined after 24 hours.<BR>The HF etching enhanced bond strength of all luting materials. Surface preparations for mechanical retention were effective for conventional glass-ionomer materials, nevertheless silane treatments gave negative effects. Application of the silane primer was effective for resin-modified glass-ionomer materials. Especially, conbined use of the surface preparation of HF and silane treatment was the most effective in enhancing bond strength of resinmodified glass-ionomer materials.
