“…A bond strength of 49.7±11.9 MPa was obtained compared to 27.2±4.8 MPa [23] but the standard deviation was quite high for the study. However, the difference between the two studies was in [40] the ceramic surface was air abraded with 30 μm Al 2 O 3 in addition to 9% hydrofluoric acid etching and the specimens were, interestingly, not subjected to water storage [23,40]. Some other studies have found that etching with 8% hydrofluoric acid and silanization was not as effective as air abrading the ceramic surface with 50 μm Al 2 O 3 followed by 8% hydrofluoric acid etching and silanizing.…”

The purpose of surface treatment (conditioning) methods on dental ceramics is to improve the retention and bonding between the enamel or the dentin and ceramic veneer, with the help of resin composite luting cements. These types of surface treatments include chemically altering the surface of ceramics with some specific acidic etchants followed by applying a silane coupling agent (silane). The silane currently used in dentistry is 3-methacryloxypropyltrimethoxysilane, a hybrid organic-inorganic trialkoxy ester monomer, which is diluted in an acidified water-ethanol solvent system. Such silane primers are said to be pre-hydrolyzed. Some oxide ceramics with high crystalline content, such as alumina and zirconia, cannot be easily etched with acid etchants. They should be silica-coated and silanized prior to bonding. A silane coupling agent should be applied after silica-coating to the ceramic surface to achieve chemical bonding and the optimal durable bond strength.

“…Etching with hydrofluoric acid leaves a significant amount of crystalline debris precipitate at the ceramic surface. 25 For this reason, laminates were ultrasonically cleaned in distilled water for 5 minutes. Thereafter, the cementation surfaces were silanized (Monobond S, Ivoclar Vivadent) and waited for its reaction for 1 minute.…”

“…The process of silanization promotes the wettability of the substrates and further reacts with the glass particles present on the composite surface forming covalent bonds [7,19]. Composite-composite bond strength simulating aging after silica coating and silanization was reported to deliver significantly higher bond strengths (46-52 MPa) than conditioning the composite substrate with phosphoric acid and adhesive resin application only (16)(17)(18)(19)(20)(21)(22)(23)(24)(25) [18]. Unfortunately, the previous clinical studies did not report application of any surface conditioning method prior to cementation of ceramic laminates [3,14].…”

Clinical longevity of ceramic laminate veneers bonded to teeth with and without existing composite restorations up to 40 months

OBJECTIVES: This study evaluated the survival rate of ceramic laminate veneers bonded to teeth with and without existing composite restorations (ECR). MATERIALS AND METHODS: Twenty patients (mean age: 49.7 years) received 92 feldspathic ceramic laminate veneers (Shofu Vintage AL) on the maxillary teeth (intact teeth: n = 26; teeth with ECR: n = 66). Preparations with incisal overlap were made, and ECR of good quality were not removed but conditioned using silica coating (CoJet) and silanization (ESPE-Sil). Enamel and dentin were etched with 38% H3PO4 for 15-30 s and rinsed 30 s; adhesive resin (Excite) was applied, and laminate veneers were then cemented (Variolink Veneer). Restorations were evaluated at baseline and thereafter every 6 months using modified United States Public Health Service criteria. RESULTS: Mean observation period was 21.6 months. Overall, five absolute failures were encountered (fractures: n = 3; chipping: n = 1; debonding: n = 1), resulting in a survival rate of 94.6% (Kaplan-Meier). Survival rates of the laminates bonded to teeth without (96%) and with ECR (93.5%) did not show significant differences (p > 0.05). Slight marginal defects (16 of 87 laminates) and slight marginal discoloration at the margins were noted (12 of 87 laminates) until the final recall. Secondary caries and endodontic complications were not detected in any of the teeth. CONCLUSION: The clinical survival of ceramic laminate veneers up to 40 months was not significantly influenced when they were bonded onto intact teeth or onto teeth with ECR. CLINICAL RELEVANCE: When no caries is present, it may not be necessary to replace existing composite restorations prior to cementation of ceramic laminate veneers.

“…6). Before cementation, each veneer was etched chairside with hydrofluoric acid, cleaned in an ultrasonic bath to remove crystalline precipitate 31 and silanated. A layer of adhesive resin (Optibond FL adhesive) was placed on the fit surface followed by a thin layer of a translucent enamel shade of nanohybrid composite (Miris 2, Coltene-Whaledent) which had been preheated for at least 15 minutes at 54°C using a Calset Composite Warmer (AdDent Inc).…”
