This book was released on 2021 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Introduction: There is a growing demand for esthetic appliances during orthodontic treatment, with a specific interest in WildSmiles shaped brackets amongst children and adolescents. Bond failure of brackets over the course of orthodontic treatment can result in increased treatment time, increased overhead costs, and feelings of frustration for the patient and practitioner. Objective: The purpose of this study was to the evaluate the effect of orthodontic bracket base shape on shear bond strength (SBS) to human enamel, in vitro, at two time points, as well as the nature of debonding fractures using the Adhesive Remnant Index (ARI). Methods: Orthodontic brackets with different shaped bases (flower, heart, rectangular) were bonded to 120 extracted human third molars. SBS was measured using a Servohydraulic Test System at 24 hours and 2 months after initial bonding. ARI scores were evaluated under 10x magnification to assess the amount of resin left on the tooth. Results: The control bracket with a rectangular base shape had the highest mean SBS (26.78 ± 8.19 MPa), and significantly differed from flower (17.19 ± 4.45 MPa) and heart (18.86 ± 3.50 MPa) base shapes (p 0.001). The mean SBS of flower and heart shaped brackets did not differ considerably from each other (p 0.05). The mean SBS between debond times at 24 hours (21.50 ± 7.46 MPa) and 2 months (20.38 ± 6.69 MPa) were not statistically significant (p > 0.05). Analysis of ARI scores showed a significant difference between Flower-24 hours vs Heart- 2 months (p=0.039), Flower-24 hours vs Heart- 24 hours (p=0.004), and Control-2 months vs Heart-24 hours (p=0.015). The heart shaped bracket had a greater proportion of adhesive bond failures at the enamel-resin interface. Conclusion: Bracket base shape has an effect on SBS, with the rectangular base shape having a higher mean SBS compared to flower and heart base shapes. All bracket shapes had bond strengths above the clinically acceptable range of 6-8 MPa, and thus may provide adequate SBS in a clinical situation. Variations in ARI scores occurred based on bracket shape and were of a mixed adhesive-cohesive nature.

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.

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.

Book Synopsis Shear Bond Strength of Brackets Adhered to Laser-Etch Versus Acid-Etch by : Hakam Alfaqheri
Download or read book Shear Bond Strength of Brackets Adhered to Laser-Etch Versus Acid-Etch written by Hakam Alfaqheri and published by LAP Lambert Academic Publishing. This book was released on 2011-10 with total page 132 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many studies have been done on the shear bond strength of brackets adhered to acid-etched enamel and so far, there is no study on shear bond strength of brackets adhere to laser-etched enamel in Iraq. So, this study is an attempt to compare the shear bond strength of brackets adhered to laser-etched enamel with that of brackets adhered to acid-etched enamel. The application of laser irradiation to etch dental enamel for direct bonding of orthodontic appliance has been studied. CO2 (Carbon Dioxide) laser are capable of producing surface irregularities in human enamel which resemble those resulting from etching of enamel with ortho-phosphoric acid. Whether laser conditioning improves the retention of composite resins to the same degree as conventional acid-etching techniques has been the subject of several investigations.
Book Synopsis Comparing Two Orthodontic Brackets' Bond to Fluorosed and Non-fluorosed Enamel by : Serufe Emily Monehi

This book was released on 2014 with total page 174 pages. Available in PDF, EPUB and Kindle. Book excerpt: Orthodontic attachments must be able to bond to a wide range of tooth and prosthetic surfaces. Despite the high prevalence of fluorosis in many parts of South Africa (Louw A, Chikte U 1997), only limited information is available on the integrity of the bond between orthodontic brackets and fluorosed teeth. The objective of this study was to measure and compare Shear Bond Strengths (SBSs) of metal and ceramic orthodontic brackets on fluorosed and non-fluorosed teeth. One hundred and twenty (60 fluorosed and 60 non-fluorosed) extracted premolar teeth were divided into four groups A to D, consisting of 30 teeth in each group. BluGloo® was used as an orthodontic adhesive to bond brackets on the buccal surface of each tooth. The experimental groups consisted of Group A, in which Nu-Edge® metal brackets were used and Group B, in which InspireIce® ceramic brackets were bonded to fluorosed teeth. Group C and D consisted of Nu-Edge® metal brackets and InspireIce® ceramic respectively, bonded to non-fluorosed teeth. Bonding techniques were kept the same and standardised for all four groups. An Instron testing device was used to debond and measure the SBSs. SBSs were compared using ANOVA with posthoc analysis done using Dunnett’s C test for pairwise comparisons. Significance was set at P0.05. The results showed that SBS of Group BGroup C>Group D>Group A. Ceramic brackets bonded to fluorosed teeth had the highest SBS with a mean of 15.78 (SD=9.07) Megapascals (MPa), while metal brackets bonded to fluorosed teeth produced the lowest SBS of 8.41 (SD=4.68) MPa. The SBSs of ceramic brackets bonded to fluorosed teeth was significantly higher than that of SBS of metal brackets bonded to fluorosed teeth, but not significantly different from SBSs obtained from either brackets bonded to non-flurosed teeth. The BluGloo adhesive if used to bond ceramic brackets to fluorosed teeth can produce adequate SBS for clinical use. The recommendation from this study is that ceramic brackets can be used efficiently to bond to fluorosed teeth. A follow up study should be carried out to assess the nature of enamel damage caused during debonding of flourosed teeth. This is a laboratory study and thus the clinical application should be interpreted with caution.
