Whitlock and published by . This book was released on 1992 with total page 120 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this study was to compare the bond strengths of three adhesive systems (two-paste, no-mix, and one light-activated) when used alone and combined with a porcelain priming agent to bond ceramic brackets to porcelain surfaces. Sixty porcelain specimens were randomly assigned to the six different treatment groups. One half of the groups were bonded with the porcelain priming agent and one of the adhesive systems and the other half with one of the adhesive systems without the priming agent. The shear bond strengths, expressed in megapascals (MPa), of all specimens were tested, using an Instron testing machine, 10 minutes after being bonded. The surface of the porcelain and the bracket base were examined, using the scanning electron microscope (SEM), to determine the bond failure patterns and check the prcelain surface for the presence of cracks and fractures. Across the three different adhesive systems, mean shear bond strength measurements ranged from 6.3-7.5 MPa when the porcelain primer was used and from 1.8-3.8 when the porcelain primer was not used. There was a statistically significant difference within each adhesive between those samples with the priming agent (mean shear bond strength of 6.5 ± 0.8, 7.5 ± 1.0, and 6.3 ± 1.2) and those without the priming agent (mean shear bond strength of 3.8 ± 0.4, 1.8 ± 1.8, nad 2.6 ± 1.3) (p ≤ 0.5). Differences between the three adhesives were not statistically significant (p ≤ .05). Evaluation of the bond failure sites, using the SEM, revealed failures at the porcelain-adhesive interface, within the adhesive and at the bracket-adhseive interface for the porcelain primer samples. The samples that were bonded with the different adhesives only displayed a failure exclusively at the porcelain-adhesive interface. The failure patterns were verified by qualitative energy dispersive x-ray analysis (EDS). It can be concluded from this study that using any of the three adhesive systems combined with the porcelain priming agent will provide sufficient bond strength to withstand normal orthodontic forces and not damage the surface of the porcelain when debonded.

Available in PDF, EPUB and Kindle. Book excerpt: Orthodontics is a fast developing science as well as the field of medicine in general. The attempt of this book is to propose new possibilities and new ways of thinking about Orthodontics beside the ones presented in established and outstanding publications available elsewhere. Some of the presented chapters transmit basic information, other clinical experiences and further offer even a window to the future. In the hands of the reader this book could provide an useful tool for the exploration of the application of information, knowledge and belief to some orthodontic topics and questions.

This book was released on 2013 with total page 108 pages. Available in PDF, EPUB and Kindle. Book excerpt: Objective: To compare the mean bond strengths and mode of bond failure, in vitro, of five bonding systems (MIP 1, Plastic Conditioner 2, Assure 2, Scotchbond 3, and Transbond XT 1), when bonding an orthodontic bracket to an artificially-aged composite resin restoration, with and without mechanical surface preparation with a diamond bur. Methods: Class V buccal composite resin restorations were prepared in 240 upper right central incisor dentoform teeth. The restorations were artificially age d for 35 days, bonded with metal brackets, stored in distilled water at 37°C for 30 days, thermocycled for 500 cycles, and subsequently debonded with an Instron universal testing machine. Results: The mean bond strengths for Transbond, MIP, Plastic Conditioner, Assure, and Scotchbond groups were 12.1, 12.3, 13.3, 17.2, and 17.7 MPa respectively. The mean bond strengths for Transbond+Diamond, MIP+Diamond, Plastic Conditioner+Diamond, Assure+Diamond, and Scotchbond+Diamond groups were 18.5, 16.4, 19.1, 19.5, and 20.7 MPa respectively. ANOVA revealed a statistically significant diffe rence (P d"0.05) among the groups. Conclusions: Mechanically roughening the surface of a composite resin restoration with a diamond bur, provided significantly greater bond strengths, regardless of the bonding resin used. However, Assure and Scotchbond, without diamond bur preparation, provided similar bond strengths to Transbond, MIP and Plastic Conditioner, with diamond bur preparation. 1. 3M Unitek, Monrovia CA 2.

Book Synopsis Influence of Orthodontic Bracket Bonding Protocol on Zirconia Ceramics and Resulting Bond Strength, Adhesive Remnant, and Debonded-Polished Zirconia Surface Roughness by : Kaylee Anne Bergman
Download or read book Influence of Orthodontic Bracket Bonding Protocol on Zirconia Ceramics and Resulting Bond Strength, Adhesive Remnant, and Debonded-Polished Zirconia Surface Roughness written by Kaylee Anne Bergman and published by . This book was released on 2019 with total page 46 pages. Available in PDF, EPUB and Kindle. Book excerpt: Objective: This study evaluated the effect of primer protocol for metal orthodontic brackets bonded to zirconia ceramic and resulting shear bond strength (SBS), adhesive remnant index (ARI), and debonded and polished zirconia surface roughness. Methods: Zirconia specimens were milled, glazed, embedded in acrylic resin and the target area microetched with aluminum oxide. Glazed and microetched representative specimens were evaluated with energy dispersive spectroscopy (EDS). Specimens were randomly assigned to primer protocol, enamel (TransbondTM Plus Self-Etching Primer) or zirconia (Assure® Plus), and primed according to manufacturer instructions. Metal orthodontic brackets were bonded to the primed surface with resin adhesive (Transbond XTTM) and light cured. To simulate intraoral conditions, all primer and bonding protocols took place in an environmental chamber set at 33±2°C and 75±5% humidity followed by a 24-hour dark cure at 37 C. Following SBS testing, an ARI value was assigned to debonded brackets. Residual adhesive was removed from the debonded zirconia specimens, the zirconia surface polished, and surface roughness measured using a profilometer. Scanning electron microscopy (SEM) was performed for qualitative evaluation of the zirconia surface. Results: Zirconia substructure exposure by aluminum oxide microetching was verified with EDS. A significantly lower (p

Available in PDF, EPUB and Kindle. Book excerpt: AIM: 1. To determine in vitro bond strength of metal and ceramic orthodontic brackets when using etch and separate primer, or self-etching primer (SEP) 2. To assess remaining adhesive following removal of orthodontic bracket METHOD: 180 previously extracted teeth were randomly allocated to one of six test groups. Each was subjected to either separate etch and primer or SEP and then bonded with an orthodontic bracket. These were metal (3M Unitek Victory), metal reinforced ceramic (3M Unitek Clarity) and poly-crystalline ceramic (3M Unitek Transcend). Samples were stored at 37 degrees C for 24 hours. Each bracket was debonded using shear force applied by the Instron Universal testing machine. Samples were examined under x10 light microscopy and allocated an Adhesive Remnant Index (ARI) score. RESULTS: Variation in shear bond strength (SBS) was seen across all groups. Lowest SBS was recorded with Victory series brackets bonded with SEP (7.08 MPa) and the highest was with Clarity series brackets bonded with separate etch and primer (15.96 MPa). Pooled data showed significantly higher SBS with separate etch and primer than SEP (T=2.83, p

This book was released on 2000 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Bonding orthodontic attachments to porcelain can be challenging. The purpose of this study was to investigate the 24 hour and 6 month shear bond strengths of orthodontic buttons bonded to porcelain using six different surface preparations: (1) Pumice polish for 5 seconds and 37% phosphoric acid etch with or (2) without the use of a silane primer, (3) microabrasion with 90[mu] aluminum oxide for 5 seconds with or (4) without the use of a silane primer and (5) hydrofluoric acid etch for 120 seconds with or (6) without the use of a silane primer. For each of the six experimental surface treatment groups, two orthodontic buttons were bonded to each of ten flat porcelain surfaces. The bonded test assemblies were shear tested to failure after 24 hour and 6 month storage at 37C and 100% R.H. The shear bond strengths were calculated and analysed using the single ANOVA and Tukey's multiple comparison test. When compared to 24 hour results, the samples treated with microabrasion and silane, hydrofluoric etch and silane and hydrofluoric etch alone underwent no significant reduction in mean bond strength (p> 0.05). The samples treated with microabrasion and silane, microabrasion alone and pumice polish alone underwent significant reductions in mean bond strength (p
