The aim of the study was to evaluate the shear bond strength of different core/veneering ceramic systems compared to the well-known metal/ceramic frame-works. In particular, the null hypothesis tested is that there is no difference in terms of bond strength between different cores. Other purposes of the study were to specifically analyse Bonding Strength Evaluation on Metal/Ceramic Interfaces Jan 01, 2012 · The higher mean values of bond strength observed in the sandblasted samples versus non sandblasted ones, comparing within the B-type series, must be due to the increase of the contact surface between metal and 481 N. Nieva et al. / Procedia Materials Science 1 ( 2012 ) 475 â 482 ceramic; this had already been observed in other metal
The SBS of the ceramic brackets in each group was less than the bond strength reported by Reddy et al. 9 and Uysal et al. 10 but comparable to the bond strength demonstrated by Bishara et al. 11 and Zielinski et al. 12 Although the SBS of the APC Flash-Free group was significantly greater than that of the other two groups, all three methods of Designs of bond strength tests for metal-ceramic complexes Despite the popularity of metal-ceramic restorations, the bonding mechanism remains the subject of theoretical discussion. Different experimental designs to evaluate bond strengths at the metal-ceramic interface are described. The effects of various stresses with each design are also discussed. A predictive experimental design should minimize variables and result in the least residual EVALUATION OF THE SHEAR BOND STRENGTH OF Due to the increase in the number of adults seeking orthodontic treatment, new challenges have risen for orthodontists, such as the need to bond orthodontic brackets to ceramic restorations, whose glazed surfaces are not amenable to resin penetration and have a higher degree of failure compared with bonding to enamel. The aim of this study was to conduct an inclusive and substantial analysis
The aim of this study was to conduct an inclusive and substantial analysis of the factors affecting shear bond strength (SBS) of metallic and ceramic orthodontic brackets bonded to different ceramic surfaces used for prosthetic restorations. EVALUATION OF THE SHEAR BOND STRENGTH OF substantial analysis of the factors affecting shear bond strength (SBS) of metallic and ceramic orthodontic brackets bonded to different ceramic surfaces used for prosthetic restorations. The research was conducted with 144 ceramic specimens of three different types (feldspar-porcelain Evaluation of The Shear Bond Strength of Laser Evaluation Of The Shear Bond Strength Of Laser Sintered Alloy, ceramic applied around metallic patterns in a semi-circle shape, or applied over a flat metal surface, in order to avoid tensions on ceramic. The circular-planar interface shear test, which provides easy fabrication and

O objetivo deste trabalho foi avaliar a resistência ao cisalhamento entre as porcelanas de cobertura e a infraestrutura de dois materiais estéticos:In-Ceram Alumina e zircônia, e uma liga metálica (Cr Evaluation of shear bond strength of orthodontic resin the highest shear bond values when compared to Vitremer (5.5 ± 3.2 MPa). The ceramic bracket (8.3 ± 2.9 MPa) obtained shear bond strength values higher than metallic brackets (5.4 ± 3.9 MPa). Table II Means and standard deviations of the shear bond strength (MPa) of the tested groups* Bracket type Bonding material Evaluation of the Bond Strengths between Dental Porcelain B. Henriques, D. Soares, and F.

Shear Bond Strength Test. The shear bond strength test was performed using a universal testing machine (LFplus, Ametek, Inc., Largo, FL) with a crosshead speed of 0.5 mm/min. A load was applied to the adhesive interface of the mounted specimen until failure occurred and the corresponding software recorded the maximum force (Mpa). Shear Bond Strength of Ceramic Brackets with Different Nov 01, 2016 · Knowledge about the Shear Bond Strength (SBS) of ceramic brackets with different base design is essential as it affects bond strength to enamel. Aim The aim of the present study was to evaluate and compare the effect of base designs of different ceramic brackets on SBS, and to determine the fracture site after debonding. Shear bond strength of ceramic and metallic orthodontic Jan 25, 2017 · Uysal T, Ustdal A, Kurt G. Evaluation of shear bond strength of metallic and ceramic brackets bonded to enamel prepared with self-etching primer. Eur J Orthod. 2010; 32 (2):2148. doi:10.1093/ejo/cjp035. [Google Scholar]
Aims:The aim of this in vitro study is to evaluate shear bond strength (SBS) of metal and ceramic brackets using conventional acid etch/primer and self-etch primer (SEP) adhesive systems. Methodology:Healthy, extracted 120 human premolar teeth were collected and were divided into group 1 teeth bonded with metal brackets and group 2 teeth bonded with ceramic brackets. Shear bond strength of metallic and ceramic brackets using The bond strength obtained in G1 and G2 was too low to orthodontic use. 9,14,19 The adhesive strength for G3 and G4 was a bit low for bonding orthodontic accessories, but it was acceptable. 22 The tensile strength shown in G5 and G6 was adequate according to Aasrum et al. 1 However, while Reynolds 21 recommends shear strength of 7 MPa, he also Evaluation of shear bond strength of ceramic and metal Evaluation of shear bond strength of ceramic and metal-ceramic systems used in prostheses on implants .
