Download or read book In Vitro Bond Strength of Orthodontic Brackets and Resin Composite Cement Degree of Conversion as a Function of Pre cure Temperature written by David Richard Ries and published by . This book was released on 2010 with total page 94 pages. Available in PDF, EPUB and Kindle. Book excerpt: The goal of this study was to evaluate the shear bond strength of orthodontic brackets and corresponding resin composite cement degree of conversion as function of pre-cure temperature. Orthodontic brackets were bonded to paired maxillary premolars or mandibular third molars in an environmental chamber with either room temperature (control) or warmed (68°C) resin cement. Bonding was followed immediately by shear testing of the bracket/cement/tooth interface. Residual resin cement on the bracket base was evaluated using micro-Raman spectroscopy to measure the degree of conversion of the cement from ratios of spectral peak heights at 1610cm−1 and 1640cm−1. Results showed no difference in shear bond strength or degree of conversion between room temperature and pre-warmed groups. Also, there was no difference in bond strength between premolar and third molar groups. The evidence suggests that pre-warming resin composite cement is not beneficial for increasing shear bond strength.

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.

Available in PDF, EPUB and Kindle. Book excerpt: In dentistry, Bonding is a term conventionally used to describe the use of an adhesive or cement, to hold a covering, to a stained or damaged tooth or to secure Orthodontic appliances to the teeth. The evolution of orthodontic materials in the past five decades has been a unique progress curve, characterized by periods of intense activity, with many developments, followed by long quiescent intervals. Even though acid etch technique was introduced in the mid 1950s, it took more than a decade for this practice to become a standard procedure in orthodontics on a large scale. In fact, orthodontic bonding has advanced more in the last ten years than in the last quarter of the century, like unprecedented progress with materials and technique such as glass ionomer bonding, self etching primers, new powerful light curing sources etc. The rapid pace of advancement in the field continues to challenge the clinicians to stay abreast in the race with technology. This speedy advancement in the material science has also altered the commercial life of the materials, as new material, introduced a few years ago, soon becomes obsolete. This is a possible outcome of a lack of strenuous quality control, research deficiencies and a product of aggressive marketing strategy by the commercial product companies Thus an evidence based approach must extend to orthodontic bonding materials with emphasis on the mechanical, physical and biological properties and the potential alterations induced by intra oral aging and their implications in orthodontic mechanotherapy.
Download or read book The Effect of Surface Treatments and Bonding Agents on the Shear Bond Strengths of Orthodontic Brackets Bonded to Aged Composite Resin Restorations written by Matthew Yun Sun Tse and published by . 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.

Download or read book Orthodontic Bracket Bond Strength and Resin Composite Adhesive Degree of Conversion Associated with Type of Curing Unit and Total Energy written by Natalia Henbest and published by . This book was released on 2013 with total page 53 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study examined the effect of light curing sources on shear bond strength and degree of conversion of orthodontic resin composite adhesive as function of type of curing unit and total energy, as well as evaluated the correlation between shear bond strength and degree of conversion. Curing units included in the study were plasma arc (PA), light emitting diode (LED) and quartz tungsten halogen (QTH) with 5k, 10k, or 15k mJ/cm2 of total energy delivered to the orthodontic adhesive by each unit type. Based on an analysis of variance (a =.05), there was no significant effect of type of curing source on shear bond strength; however, there was a significant effect of total energy, with shear bond strength increasing as energy increased across curing units. For degree of conversion there was a significant effect of curing unit with PA producing higher degree of conversion than LED or QTH, which were not significantly different from each other. There was also a significant effect of total energy on degree of conversion with a significant increase between 5k to 10k mJ/cm2. There was a positive moderate overall correlation between shear bond strength and degree of conversion. Results of this study suggest that the PA curing unit is more efficient at polymerization (degree of conversion) of orthodontic resin composite adhesive. However, there is no difference in shear bond strength produced when using PA, LED or QTH curing sources for orthodontic bracket bonding procedures when equal total energy is delivered to the adhesive.

This book was released on 2015-12-23 with total page 136 pages. Available in PDF, EPUB and Kindle. Book excerpt: Direct bonding of orthodontic attachment has removed some of the esthetic concerns many adults previously had when considering orthodontic therapy. With an increase in adult treatment comes the challenge of direct bonding to non-enamel surface, such as composite restoration. The big problem that faces orthodontist is debonding of the brackets specially in cases when it fixed on restoration like composite. Therefore a roughened surface will need in order to bond the adhesive composite material to the substrate composite restoration, this roughness will lead to distraction, weaken and loss of integrity of the composite restoration. This study was designed to evaluate the bonding strength of three different generations of adhesive bonding and which one is better to use for bonding the orthodontic bracket to composite restoration, without doing any roughness on composite restoration surface and compare between them which one have better bonding strength with composite restoration.
