Bond Strengths of Cements to a New CAD/CAM Resin Composite
Objectives: The aim of this study was to evaluate the bond strengths of three luting agents to CAD/CAM resin composite. Methods: Three luting agents were used for this study; 1) ESTECEM / UNIVERSAL Primer (Tokuyama Dental) 2) Panavia V5 / K-etchant GEL and Clearfil Ceramic Primer Plus (Kuraray Noritake Dental) 3) G-CEM LinkAce / Ceramic Primer 2 (GC)
The surfaces of fifteen specimens made of a newly developed CAD/CAM resin composite (ESTELITE BLOCK, Tokuyama Dental) were ground flat with #600-grid SiC paper and airborne-particle abraded. Then they were divided into three groups of five each. Stainless steel rods were bonded to the specimens’ surfaces using one of the three cements. The tensile bond strengths were tested after 24h water storage (37°C) using universal testing machine. These specimens were fractured under the tension at a crosshead speed of 1 mm/min, and the maximum load at the fracture was recorded. Average fracture loads were compared with one-way ANOVA and Dunnett T3 (p<0.05). Results: The results are presented in the table below. The bond strengths of ESTECEM was significantly higher than Panavia V5 (p<0.05). Conclusions: In this study, ESTECEM was useful for the adhesion to resin composite block for CAD/CAM system.
