Book Description
ORTHODONTICS: CURRENT PRINCIPLES AND TECHNIQUES covers the latest orthodontic concepts and treatment methods available. This definitive resource is divided into two sections: Diagnosis and Treatment Planning, which includes chapters on biomechanical principles and practice, computer applications, and principles of occlusion; and Techniques and Treatment, covering the methods and techniques currently used in treating malocclusion. Offers a clearly written and organised overview of diagnosis and treatment planning in orthodontics. Includes the latest applications in computerised cephalometrics and facial imaging. Describes bioengineering and physical science principles as applied in the practice of orthodontics. Incorporates case studies for real life examples of orthodontic treatment. Features comprehensive, step-by-step presentation of the newest treatment methods in modern orthodontics. Incorporates approximately 3000 illustrations in a two-colour format for a comprehensive visual explanation of concepts. Provides the reader with a full-colour insert of a case study from pre-treatment to an 18-year follow up. Includes six entirely new chapters: Orthodontic Therapy and the Temporomandibular Disorder Patient Biomaterials in Orthodontics Statistics for the Orthodontist TipEdge Brackets and the Differential StraightTechnique NonExtraction Treatment Treatment Options for Sagittal Corrections in NonPatients Features thoroughly revised and updated material and illustrations for the latest information in orthodontic treatment.

Book Description
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.
