“…The advantage of the airborne particle abrasion procedure over mechanical roughening with diamond burs has already been demonstrated. 26 The abrasive process removes loose contaminated layers and the resulting roughened surface provides some degree of mechanical interlocking or "keying" with adhesive agents. It can be argued that the increased roughness also forms a larger surface area for the bond.…”

“…16,18,26 The chemical coupling is achieved by the reaction of 10-methacryloxypropyltrimethoxysilane (MPS) to the silicon oxide phase in the ceramic. Particularly with feldspathic ceramics, HF acid etching combined with silane coupling agents yielded satisfactory results with respect to bond strength, and also revealed results superior to those of surface treatments with aluminum oxide air-abrasion.…”

The aim of this study was to qualitatively demonstrate surface micro-morphological changes after the employment of different surface conditioning methods on high-alumina and glassy-matrix dental ceramics. Three disc-shaped high-alumina specimens (In-Ceram Alumina, INC) and 4 glassy-matrix ceramic specimens (Vitadur Alpha, V) (diameter: 5 mm and height: 5 mm) were manufactured. INC specimens were submitted to 3 different surface conditioning methods: INC 1 -Polishing with silicon carbide papers (SiC); INC 2 -Chairside air-borne particle abrasion (50 µm Al 2 O 3 ); INC 3 -Chairside silica coating (CoJet; 30 µm SiO x ). Vitadur Alpha (V) specimens were subjected to 4 different surface conditioning methods: V 1 -Polishing with SiC papers; V 2 -HF acid etching; V 3 -Chairside air-borne particle abrasion (50 µm Al 2 O 3 ); V 4 -Chairside silica coating (30 µm SiO x ). Following completion of the surface conditioning methods, the specimens were analyzed using SEM. After polishing with SiC, the surfaces of V specimens remained relatively smooth while those of INC exhibited topographic irregularities. Chairside air-abrasion with either aluminum oxide or silica particles produced retentive patterns on both INC and V specimens, with smoother patterns observed after silica coating. V specimens etched with HF presented a highly porous surface. Chairside tribochemical silica coating resulted in smoother surfaces with particles embedded on the surface even after air-blasting. Surface conditioning using air-borne particle abrasion with either 50 µm alumina or 30 µm silica particles exhibited qualitatively comparable rough surfaces for both INC and V. HF acid gel created the most micro-retentive surface for the glassy-matrix ceramic tested.

“…In order to improve adhesion to ceramic materials, various ceramic surface treatments have been developed. Mechanical roughening with a coarse diamond bur 12) , air-abrasion using alumina particles 13) , and chemical etching with hydrofluoric acid 14) have been shown to provide micromechanical interlocking at the ceramic-resin interface. Moreover, it has been reported that the applications of silane coupling agent and acidic functional monomer could produce chemical bonding to silica-based and zirconia ceramic materials [15][16][17] .…”

This study evaluated the effects of ceramic surface treatment agents on shear bond strengths to ceramic materials with and without thermocycling. Ceramic plates were prepared from feldspathic ceramic; AAA, lithium disilicate ceramic material; IPS e.max Press, zirconia ceramic; Lava. Ceramic surfaces were pretreated with one of five surface treatment agents (Clearfil PhotoBond mixed with Porcelainbond activator (PB), Clearfil SE One mixed with Porcelainbond activator (SO), Ceramic Primer (CP), Universal Primer (UP), Scotchbond Universal (SU)), and then a resin cement (Clapearl DC) was filled. After 0, 5,000, and 10,000 thermocycles, micro-shear bond strengths between ceramic-cement interfaces were determined. SU exhibited significantly lower initial bond strength to AAA and e.max than PB, SO, CP, and UP. For Lava, PB, SO, CP and SU exhibited higher initial bond strengths than UP. Thermocycles reduced bond strengths to all the ceramic materials with any surface treatment.

“…These primers typically contain a silane coupling agent (such as γ-methacryloxypropyltrimethoxysilane (γ-MPS)) and an acidic monomer (such as 4-methacryloyloxyethyl trimellitic acid (4-MET) or 10-methacryloyloxydecyl dihydrogen phosphate (MDP)) [1][2][3][4][5] . However, these studies offered no information on whether the acidic group in 4-MET or MDP provided a sufficient amount of dissociated protons to induce the hydrolysis of methoxy group in γ-MPS and facilitate its chemisorption.…”

Effects of degree of dissociation of acid used on hydrolytic durability of ceramic primer

et al. 2014

In this study, effects of the degree of dissociation of acids on the hydrolysis rate of methoxy group in γ-methacryloxypropyltrimethoxysilane (γ-MPS) and the adsorption characteristics of γ-MPS on ceramic surfaces were studied using acetic, phosphoric, and hydrochloric acids. Hydrolytic stability of γ-MPS adsorption layer at the resin-ceramic interface was thus examined.29 Si NMR observations of acidactivated γ-MPS and contact angle measurements following ceramic surface silanization were performed. Bond strengths of resin to the silanized ceramic surfaces were measured. Statistical analyses of shear bond strength and contact angle data were performed. Increase in the degree of dissociation of the acid used increased the hydrolysis rate of methoxy group in γ-MPS, but lowered the contact angle to the silanized ceramic surface. Decrease in the contact angle increased the hydrolytic stability of γ-MPS adsorption layer.
