This book was released on 2011 with total page 118 pages. Available in PDF, EPUB and Kindle. Book excerpt: Objective: To assess the mechanical effects of nickel-titanium orthodontic archwire flaming and their distribution along the wire. Methodology: Two sizes of pre-formed austenitic nickel-titanium archwires were tested (n=10). The terminal 5mm of each wire was heated for five seconds using a butane lighter. Micro-hardness testing was used to determine the heat-affected zone for all wires. Cantilever bending was performed to assess the mechanical properties of heated wires. Results: The heat-affected zone was found to extend less than 2 mm past the flame boundary for all wires. For each wire gauge, the flamed zone was characterized by a lower and flatter super-elastic plateau and an increased tendency for plastic deformation when compared to controls. Conclusions: The limited ability of austenitic nickel-titanium orthodontic archwires to conduct heat past the boundary of the flamed region suggests no need to alter current clinical practice.

Available in PDF, EPUB and Kindle. Book excerpt: Orthodontic Applications of Biomaterials: A Clinical Guide reviews the applications of biomaterials and their effects on enamel preparation, bonding, bracket and archwire ligation, mechanotherapy, debonding, and long-term enamel structural, color, and surface effects. The book provides a step-by-step analysis of the phenomena occurring, their clinical importance, and their underlying cause without the use of complex mathematical or physical-chemical analyses, with the goal of providing 'digestible' evidence for the clinician. - Serves as a reference source of the spectrum of biomaterials used in orthodontics - Presents the most current evidence of state-of-the-art methods of materials research - Provides substantiation for the effects occurring during the materials' uses

Available in PDF, EPUB and Kindle. Book excerpt: This study examined the effect of exposure to bracket-related load deflection on the mechanical properties and surface characteristics of esthetic coated and uncoated nickel titanium archwires. Two types of coated archwires were tested: one with a rhodium ion coating and another with a polymer coating. Corresponding uncoated wires of the same size were also tested. These four different wires were divided into treatment groups based on exposure to bracket-related load deflection and storage in PBS at 37±1°C. A three-point bend test in DI water at 37±1°C was performed on specimens at three time points: 4 weeks, 8 weeks, and 12 weeks. Unloading forces at 1, 2, and 3 mm of deflection were recorded. After 12 weeks exposure, three representative specimens from each treatment group along with untested wires were viewed using scanning electron microscopy (SEM) to provide a qualitative surface topography analysis. Results of the present study showed that no significant differences (p > 0.05) in unloading force were present in wires exposed to bracket-related load deflection. However, significant differences were observed between coated and uncoated wire types (p

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.
