The effects of various surface treatments on the bond strength between lithium disilicate pressed-ceramics and luting agent

抄録

Purpose: This study aimed to evaluate the effects of various surface treatments, including resin coating, on the bond strength between lithium disilicate ceramics and luting agent. Materials and Methods: All specimens were air-abraded with alumina particles and separated into the following four groups based on the surface treatment method used: silane coupling agent (PA); multipurpose ceramic/metal primer (CP); multipurpose ceramic/metal primer with resin coating (CM); and silica coating with multipurpose ceramic/metal primer followed by resin coating (RM). A luting agent was placed on the treated surface and photopolymerized. The shear bond strengths of the materials were measured after 10,000 thermal cycles. Results: The bond strengths of the specimens in the PA group were significantly higher than those in the CP group. CM and RM groups presented with significantly higher bond strengths than CP. Conclusion: The combination of multipurpose ceramic/metal primers and resin coating can significantly increase the bond strength between lithium disilicate ceramics and luting agent.
