Effect of Different Surface Treatments on Bond Strength of Resin Cement to a CAD/CAM Restorative Material

Abstract

Surface treatments of hybrid ceramic resin blocks could enhance the bond strength to resin cement; however, using Single Bond Universal without surface treatment showed a higher bond strength value.

The Effect of Surface Treatments on the Mechanical and Optical Behaviors of CAD/CAM Restorative Materials

“…Erbium‐doped: yttrium, aluminum, and garnet (Er:YAG) laser shows similar effects on tissues and dental materials since the wavelength of Er:YAG laser (2.94 nm) is close to that of Er,Cr:YSGG laser (2.78 nm) . Erbium lasers were evaluated in previous studies in terms of bond strength of lithium disilicate ceramics and composite resins to resin cement; however, the results are inconsistent, because the power settings of lasers and irradiated material affected the surface alterations . In this study, Er,Cr:YSGG laser was applied at two energy settings (2 and 3 W) and with 55% water because when Er,Cr:YSGG laser is applied to dental materials, the laser interacts with exogenous water for ablation.…”

“…For glass‐ceramics, hydrofluoric acid (HFA) etching is accepted as gold standard because the glassy matrix is dissolved and crystalline phase is exposed after acid etching, and the surface of the ceramic becomes available for micromechanical interlocking of resin cement . The efficacies of HFA etching, airborne‐particle abrasion, tribochemical silica coating, and erbium, chromium: yttrium, scandium, gallium, and garnet (Er,Cr:YSGG) laser irradiation have been evaluated in terms of bond strengths of the novel CAD/CAM materials to resin cement.…”

Microtensile Bond Strength of CAD/CAM Resin Blocks to Dual‐Cure Adhesive Cement: The Effect of Different Sandblasting Procedures

“…Kassotakis et al revealed that Al 2 O 3 , CoJet, and Siljet showed similar μTBS results on luting CAD/CAM restoratives; however, they reported that aluminum oxide‐based sandblasting powders provided the best surface treatment of CAD/CAM systems . Barutcigil et al examined the effect of CoJet and 50‐μm Al 2 O 3 powder on shear bond strength of resin cement to CAD/CAM restoratives, reporting 8.75 MPa bond strength values from CoJet‐treated surfaces and 9.13 MPa from 50‐μm Al 2 O 3 ‐treated surfaces. Accordingly, in our study, specimens sandblasted with 50‐μm Al 2 O 3 powders exhibited higher μTBS values than those treated with 27‐μm Al 2 O 3 and 30‐μm CoJet.…”

“…Thus, silane provides chemical bonding between different materials . Several articles reported that silanization improved the bond strength of CAD/CAM restoratives to resin cements by providing chemical bonding between the materials …”

“…22 Several articles reported that silanization improved the bond strength of CAD/CAM restoratives to resin cements by providing chemical bonding between the materials. [23][24][25] Sandblasting is an established method for increasing the bonding surface on CAD/CAM resin restoratives; however, in the most current literature, Yoshihara et al 26 reported that sandblasting may damage the surface of composite CAD/CAM blocks. The manufacturers of Cerasmart (GC Corporation, Tokyo, Japan), LAVA (3M ESPE, St Paul, MN), and VITA (Vita Zahnfabrik H. Rauter, Bad Säckingen, Germany) recommended that CAD/CAM blocks be sandblasted using 25-to 50-µm sand.…”
