Shear bond strength of a self-etched resin cement to an indirect composite: Effect of different surface treatments

Abstract

In Shear bond strength of resin, cement was independent of the surface conditioning methods applied on tested indirect resin composite.

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

“…Kimyai et al examined the impact of three methods of surface treatment, 2W Er,Cr:YSGG laser, air abrasion, and diamond bur application, on the repair bond strength of a laboratory composite and confirmed the effect of Er,Cr:YSGG laser on laboratory composite repair . Furthermore, in a recent study, different power settings (1.5, 2, and 3 W) of Er,Cr:YSGG laser were compared on indirect resin composite, and no differences were determined between power settings . In this study, 2 W and 71 J/cm 2 energy density Er,Cr:YSGG laser was used.…”

“…33 Furthermore, in a recent study, different power settings (1.5, 2, and 3 W) of Er,Cr:YSGG laser were compared on indirect resin composite, and no differences were determined between power settings. 34 In this study, 2 W and 71 J/cm 2 energy density Er,Cr:YSGG laser was used. This method was found to be as effective as Al 2 O 3 sandblasting and CoJet in accordance with the previous reports.…”

Micro-shear bond strengths of resin-matrix ceramics subjected to different surface conditioning strategies with or without coupling agent application

“…The procurement of a durable bond between machine-milled restorations and luting cement by the genesis of chemical bonds and mechanical interlocking is one of the major climacterics influencing the long-term viability of prosthetic treatment as poor bonding may lead to low fracture strength, low retention, inferior marginal fit, and micro-leakage. 1 2 3 4 5 6 As attempts to achieve a durable bond, manifold micromechanical (mechanical, chemical, and laser irradiation) and chemical (silicon coatings, use of coupling agents) surface conditioning strategies are in use. 1 2 3 4 7 8 9 10 …”

“… 14 Of these; air-borne particle abrasion (APA) and laser irradiation (LI) are common. 5 15 16 In APA, the substrate surface is roughened by throwing abrasive particles. 17 18 Although being a well-established strategy; 6 9 18 it has a propensity for surface-damage 1 9 and microcrack creation.…”

“… 14 Although several types have emerged to roughen ceramics; 4 11 14 the use of erbium, chromium-doped yttrium, scandium, gallium, and garnet (Er,Cr:YSGG) laser has recently been widespread. 1 2 4 5 16 Due to its hydrokinetic nature, there is less risk of forming a heat-damaged layer. 4 15 …”
