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.

Book excerpt: In this important new textbook all scientific and clinical aspects of orthodontic materials are described.Recent developments in science and technology have led to the introduction of a plethora of new orthodontic products. This work serves as an excellent source of information for a field that requires knowledge of basic elements of materials science, engineering, chemistry, and physics, as well as clinical orthodontics. The subject has been part of graduate orthodontic education for almost three decades. Besides servicing the orthodontic training programs, the book also - investigates the interactions of orthodontic materials with other dental materials as well as hard tissues in the oral cavity,- gives a background to allow for proper material selection for efficient orthodontic mechanics,- treats the issues of biocompatibility, cytotoxicity and mutagenicity of materials.

This book was released on 2013 with total page 76 pages. Available in PDF, EPUB and Kindle. Book excerpt: Traditional bonding materials are incapable of bonding in presence of moisture, are challenged by "Moist-field" bonding materials. Claims and counter claims are made regarding their, efficacy to use as ideal orthodontic bonding adhesives. Present study done to compare Shearbondstrength of Ethyl cyanoacrylate(Smart Bond) and self cure acrylic(Rely-a-Bond) under different conditions. Rely-a-Bond and Smart Bond, are acceptable bonding materials in dry and wet conditions respectively with regards to Shear bond strength values per se. Rely-a-Bond showed significant increase in Shear bond strength from 1 hour to 24 hours. Smart Bond shows significant decrease in Shear bond strength over time. Rely-a-Bond has significantly increased Shear bond strength than Smart Bond at all times. Rely-a-Bond has high probability of failure at 1 hour; however show drastic improvement at 24 hours. Hence usage of Rely-a-Bond, force application should be deferred for 24 hours. Smart Bond adhesive is unsuitable for use as a bonding agent in routine orthodontic practice. However, the ability of this adhesive to adhere to wet surfaces could enable practitioners to bond attachments in wet conditions.

Download or read book A Comparative Study of Shear Bond Strengths of Different Combinations of Adhesive Systems and a Porcelain Priming Agent when Bonding Ceramic Brackets to Porcelain written by Boyd O. 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: The evolution of orthodontic materials in the past 5 decades has been a unique progress curve characterized by periods of intense activity with many developments followed by long quiescent intervals. An example of the delay in adopting the advances in dentistry might well be illustrated by the acid-etching technique, which was introduced in the mid 1950s1 and became universally accepted in the 1960s. It took more than a decade for this practice to become standard procedure in orthodontics on a large scale. Infact, orthodontic bonding has advanced more in last 10 years than previous 25. In the past decade, we have witnessed unprecedented progress in bonding to enamel with various materials techniques and auxiliaries involving glass ionomer bonding, self-etching primers, and new, powerful light-curing sources, along with self-ligating brackets and a different treatment concept, the Invisalign technique.

This book was released on 2012 with total page 96 pages. Available in PDF, EPUB and Kindle. Book excerpt: The following conclusions are drawn from this comparative in-vitro study on the shear bond strength and debonding characters of Transbond XT, Esthet-X Flow and Filtek Z-350 using metal brackets Filtek Z-350 has a comparable mean bond strength value (11.07+/-1.03 MPa) like that of Transbond XT (11.58+/-1.3 MPa). Esthet-X Flow has slightly lower mean bond strength value (10.70+/-2.0 MPa) compared Filtek Z-350 and Transbond XT. All the three adhesives exhibited clinically acceptable bond strength. 60-70% of all the three adhesives exhibited cohesive type of bond failure. The efficacy of the flowable composites as a bonding agent needs invivo and clinical assessment through a survival analysis. Filtek Z-350 and Esthet-X flow exhibited problems with handling properties and flowability. Drifting of brackets was noted and pressure was needed for positioning the bracket with Filtek Z-350 and Esthet-X flow. The flow property and viscosity should be balanced to obtain optimal consistency to achieve optimal bond strength and improve handling property for Filtek Z-350 and Esthet-X flow.
