Effectiveness of current adhesive systems when bonding to CAD/CAM indirect resin materials: A review of 32 publications

Abstract

SummaryThe purpose of this review was to assess the available literature regarding bonding between current adhesive systems and computer-aided design/computer-aided manufacturing (CAD/CAM) indirect resin materials, to provide clinicians with a comparative overview of the relevant bonding procedures. An electronic search was performed through PubMed based on the keywords CAD/CAM and dental bonding. Additional relevant literature was obtained from the citations in the articles. A total of 313 papers were identified, of which 281 were excluded as being unsuitable, and an additional 3 papers were identified, giving a total of 32 articles that are included in this review. Based on this survey, it is recommended that microretentive surfaces should be generated by either blasting or hydrofluoric acid etching. This initial process should be followed by silanization to ensure chemical adhesion prior to bonding to CAD/CAM indirect resin composite materials (including Lava Ultimet, KATANA AVENCIA block, Gradia Block, Cerasmart, Paradigm, and Block HC) and CAD/CAM polymer-infiltrated ceramics (such as Vita Enamic). The use of materials containing methyl methacrylate (MMA) also appears to improve the bonding of CAD/CAM poly(methyl methacrylate) (PMMA) resin materials (including XHIPC-CAD/CAM, artBloc Temp, and Telio).

Comparison of shear bond strengths of different types of denture teeth to different denture base resins

“…Yanikoglu et al 10 examined the shear bond strengths of light-polymerized composites and cold-polymerized acrylics to acrylic teeth and reported that, if an adequate bonding agent is used, enhanced bonding can be attained with a composite material. In a systematic review, Mine et al 32 concluded that materials containing methyl methacrylate improved the bonding of CAD/CAM PMMA resin materials. Previous research 10,17,32,33 and the present study results (Fig.…”

Bonding performance of dispersed filler resin composite CAD/CAM blocks with different surface treatment protocols

“…The physical adsorption is affected by surface topography (roughness) of the substrate 12,14) which will change the surface area and the wettability 15) , subsequently improve its surface energy 12) . Surface pretreatment with sandblasting (SB) is recommended by the manufacturer for all DF-RCBs 11,13,[16][17][18][19][20][21][22] to increase their roughness. SB with 50 µm alumina particles under a controlled air pressure of 0.1-0.2 MPa has been reported as the most effective method for bond durability 16) , but it may affect the fatigue strength and long-term durability of DF-RCBs 23,24) due to the development subsurface cracks (1-10 µm) 23) .…”

Clinical outcomes of single crown restorations fabricated with resin-based CAD/CAM materials

“…To obtain a strong resin bond, the dispersed nanoparticlefilled composite resin (i.e. Lava Ultimate) should be pretreated through airborne-particle abrasion with alumina particles, followed by application of silane [2,[16][17][18]. On the other hand, the resin infused ceramic hybrid (i.e.…”

“…On the other hand, the resin infused ceramic hybrid (i.e. VITA Enamic) should be applied with hydrofluoric acid etching and then silanized [2,[16][17][18]. This difference in the adhesive procedure is due to the composition of the resin-based CAD/CAM materials (Table 1).…”
