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

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.

Download or read book Bonding Orthodontic Brackets to Stainless Steel Crowns written by Daniel A. Stewart and published by . This book was released on 2009 with total page 54 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this study was to compare shear bond strengths of brackets bonded to stainless steel crowns using various orthodontic adhesives and surface conditioning techniques. One hundred and twenty mandibular first molar stainless steel crowns were randomly divided into groups: (1): Aluminablasting + Metal Primer + Assure; (2): Aluminablasting + Silane Coupling Agent + Transbond; (3): Diamond Bur Abrasion + Metal Primer + Assure; (4): Diamond Bur Abrasion + Silane Coupling Agent + Transbond; (5: control): Acid Etching + Metal Primer + Assure; (6: control): Acid Etching + Silane Coupling Agent + Transbond. Bond strength was tested using a universal testing machine. Both aluminablasting and diamond bur abrasion surface preparation techniques, when used in conjunction with metal primer and Assure bonding resin, reached clinically acceptable bond strength values (9.05 and 9.30 MPa, respectively). These techniques seem to offer viable options to bond orthodontic brackets to stainless steel crowns.

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 1991 with total page 114 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this investigation was to evaluate the effects of air-powder polishing on shear bond strength in vitro for two metal bracket adhesive systems currently in use for direct orthodontic bonding procedures. Ninety-six third molar teeth with flattened enamel surfaces were randomly assigned to be bonded with metal brackets using either a two paste or a no-mix orthodontic adhesive resin. Thwelve samples in each treatment group were air-powder polished for 0, 15, 30, or 60 seconds. Each bracket adhesive bond was then tested for shear strength using the Instron Universal Testing Device. Scanning electron microscopy determined the fracture pattern of representative samples from each treatment group. Mean shear bond strength values for each treatment group were calculated and expressed in magapascals (MPa). Values from baseline to 60 seconds varied from 22.9 ± 1.9 MPa to 18.2 ± 4.1 MPa for the two paste system and from 15.5 ± 2.1 MPa to 14.6 ± 1.9 MPa for the no-mix adhesive. Differences between the adhesive systems at all air-powder polishing times were statistically significant (p d".05). Statistical analysis by a two-way ANOVA in combination with the Newman-Keuls Multiple Range Test for pairwise mean comparisons determined a differential effect of air-powder polishing on the bond strength of the two adhesive systems. After 60 seconds of air-powder polishing, results showed a significant decrease (p d".05) in the mean bond strength of the two paste adhesive resin when compared to baseline, 15, and 30 second treatments. No significant time effect of air-powder polishing was found for the no-mix adhesive system. SEM analysis of the bond failure sites showed tooth-adhesive, within adhesive and bracket-adhesive fracture patterns for the viewed samples of each adhesive type and air-powder polishing treatment time. Fractures within tooth structure were also noted for the two paste system, indicating strong enamel-adhesive-bracket bonds. Differences in the fracture pattern of the two paste 60 second air-powder polishing group may account for the differential effect of treatment. Although in vitro results showed decreased bond strength for the two paste system, use of air-powder polishing for the routine maintenance of the orthodontic patient should not affect clinical performance of this adhesive.

This book was released on 2011-12 with total page 104 pages. Available in PDF, EPUB and Kindle. Book excerpt: Self-etching primers are the latest addition to the armamentarium of an orthodontist. Their main advantage is that they reduce the number of steps required in the bonding of orthodontic brackets. However, their low ph was a cause of concern. This book describes a study undertaken to see the effects of ph of self-etchant on shear bond strength of orthodontic brackets. These shear bond strengths were also compared to those obtained with a conventional 3-step bonding system. It was found that self-etching primers not only reduce the chair time in an orthodontist's clinic but also reduce the amount of enamel lost during etching. The bond strength achieved was less than that of the conventional bonding system but was acceptable for orthodontic purposes. Thus self-etching primers are an important and useful invention for simplifying the most critical step in orthodontic clinic- bonding.

Available in PDF, EPUB and Kindle. Book excerpt: Demineralization of enamel has been one of the iatrogenic effects of fixed orthodontic therapy, for which various authors have suggested the use of fluoride to reduce the decalcification and development of white spot lesion. In the present study, the shear bond strength of light-cure composite adhesive, self-cure composite adhesive, light-cure glass ionomer cement and acidic primer were tested at the end of 24 hours after bonding. The results proved that the acidic primer system had highest shear bond strength while Light-cure glass ionomer system had the least shear bond strength. But the mean values met the minimal shear bond strength required for orthodontic bonding. After bond failure, least amount of glass ionomer cement was present on the enamel surface, followed by acidic primer system, light-cure composite and self-cure composite system. So, it is advantageous to use light-cure glass ionomer cement for bonding in terms of less amount of time spent and no enamel damage during cleaning procedure after debonding.
