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.

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.

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.

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.

This book was released on 2004 with total page 176 pages. Available in PDF, EPUB and Kindle. Book excerpt: Conditioning and priming of unground enamel using conventional acid etchants and bonding resins has been recommended for effective bonding in orthodontics. The use of the newer single-step self-etching adhesives which etch, prime and apply the resin bonding agents simultaneously without rinsing, has been increasing in popularity. The purpose of this study was to compare the shear-peel bond strength and the amount of adhesive remaining on the tooth after debonding of a traditional two-step etch and prime technique, with a single-step alternative, when used with a composite resin adhesive system and a resin-modified glass ionomer cement system.
