“…Studies on use of dentin bonding agents for bond of composite resin to porcelain or metal are limited. Knight et al used different bonding systems in bond of composite resin to base metal and showed that the highest bond strength was obtained by All Bond 2 followed by Single Bond and Optibond FL [9]. The bond strength range of composite to non-precious metal by different surface treatments and adhesives in previous studies has been similar to the range reported in our study (2.78 to 13.72 MPa).…”

“…The bond strength range of composite to non-precious metal by different surface treatments and adhesives in previous studies has been similar to the range reported in our study (2.78 to 13.72 MPa). Gourav et al [1] showed that the bond strength values varied between 3 to 10 MPa; this value was 11 to 16 MPa in the study by Knight et al, [9] and 9-18 MPa in the study by Jain et al, [7] who reported the lowest values in Monobond S applied over bur treated surface and the highest values for the same adhesive applied over sandblasted surfaces; this was attributed to the presence of phosphate ester groups and the ability to form chemical bond with the oxide layer on the alloy surface.…”

“…Currently, some bonding systems are available providing acceptable bond strength to porcelain [8]. Bond strength to base metal alloys in different adhesive systems is highly variable and has a wide range [5,7,9]. Considering all the above, this study aimed to assess the effect of different mechanical surface preparations and different adhesive systems on shear bond strength of composite resin to a non-precious metal alloy.…”

Background and Aim: Fractured metal-ceramic restorations may be repaired with composite in some cases to postpone the fabrication of a new restoration. Knowledge about the bond strength can help predict the success rate of this treatment modality. The aim of this study was to assess the effect of two types of mechanical surface treatment of metal along with the use of different adhesive systems on bond strength of composite to a non-precious metal alloy. Materials and Methods: In this in vitro experimental study, 110 metal discs were fabricated of nickel chromium alloy and were randomly divided into two groups of surface preparation with sandblasting (S) and bur (B). In each group, the samples were divided into five subgroups based on the adhesive system and composite resin used: Group NC: Z350 composite without application of adhesive; group AC: Alloy primer/Clearfil AP-X; group ZA: Z-Prime Plus/Aelite; group MT: Monobond Plus/Tetric N Ceram; group AZ: Adper Single Bond Plus/Z250. In the positive control group (PC), metal discs were covered with feldspathic porcelain. All samples were then subjected to 1000 thermal cycles and shear bond strength was measured. Data were analyzed using one-way ANOVA, two-way ANOVA and Tukey's HSD test (P<0.05). Results: The interaction effect of type of surface treatment and type of adhesive system on bond strength was significant (P<0.05). The highest bond strength (148.7 MPa) was noted in group PC and the lowest bond strength (2.78 MPa) was noted in group B+NC. The bond strength was 13.72 MPa in group S+AZ, 10.84 MPa in group B+AZ and 12.72 MPa in group S+ZA, which did not have a significant difference with the bond strength of group PC. Conclusion: Type of surface preparation and adhesive affect the bond strength. Surface preparation by sandblasting or bur combined with the use of Adper Single Bond Plus and also combination of Z-Prime Plus adhesive and sandblasting yielded the highest bond strength value.

“…The reasons for fractures are frequently repeated stresses and strains during chewing or trauma 1–6 . Repairing CFM in vivo can increase the clinical longevity of the failed restorations, thereby offering the patient and the dentist a cost‐effective alternative to replacement; however, the repair of fractured CFM crowns represents a potential clinical challenge, particularly when the metal substructure has been exposed, and when bonding of resin to metal alloy is required 4,7 …”

“…No que diz respeito às restaurações metálicas e metalocerâmicas, como não existe uma união química eficiente entre o cimento resinoso, com ou sem adesivo ou primer para metal, e o substrato metálico, a retenção micromecânica é o tratamento de superfície mais eficiente para este tipo de restauração 4,5 . Diante desses motivos, associado à sensibilidade da técnica adesiva, tem-se dado preferência à utilização de cimentos de fosfato de zinco para cimentação de restaurações com infra-estrutura metálica.…”

Influence of Tooth Preparation Surface and Zinc Phosphate Cement on the Tensile Bond Strength of Metallic Copings Objective: To assess the tensile bond strength of silver-tin copings cemented in human dentin varying the zinc phosphate cement and tooth preparation surface. The null hypothesis was that the preparation surface and the type of zinc phosphate cement have no influence on the tensile bond strength of the metallic copings. Method: Standard full crown preparations were made on a power lathe in 60 human third molars extracted for periodontal reasons. Thirty preparations (G1) were made with diamond burs (Komet, USA) and the other 30 (G2) were made with carbide burs (Komet, USA). For each preparation, metallic copings were fabricated and cemented (axial load: 5 kg; time: 7 minutes) on the respective tooth preparation with three different zinc phosphate cements (n=10): G1a/G2a: S.S.White; G1b/G2b; DFL; and G1c/G2c: LS (Vigodent). After 48 hours of storage at 37ºC, the specimens were subjected to the tensile bond strength test (1 mm/min; 50 kgf) in a universal testing machine (EMIC). The data were subjected to statistical analysis by two-way ANOVA and Tukey's test at 5% significance level. Results: The values (kgf) obtained under the experimental conditions were the following: G1a (20.43±2.4), G1b (23.5±5.6), G1c (33.2±6.3), G2a (25.1±9.5), G2b (27.8±3.6) and G2c (32.5±8.3). The results demonstrated that tooth preparation surface did not have a significant effect (p=0.1), but the analysis of the type of cement showed that G1c and G2c were better than the other groups (p=0.001). The null hypothesis was rejected. Conclusion: The LS cement provided higher tensile bond strength values, regardless of the type of bur used for tooth preparation.
