Introduction The specialty of orthodontics has continued to evolve since its advent in the early 20th century. Changes in treatment philosophy, mechanics, and appliances have helped shape our understanding of orthodontic tooth movement. In the 1890‘s, Edward H. Angle published his classification of malocclusion based on the occlusal relationships of the first molars. This was a major step toward the development of orthodontics because his classification defined normal occlusion. Angle then helped to pioneer the means to treat malocclusions by developing new orthodontic appliances. He believed that if all of the teeth were properly aligned, then no deviation from an ideal occlusion would exist. Angle and his followers strongly believed in non-extraction treatment. His appliance, (Fig. 1), consisted of a tube on each tooth to provide a horizontally positioned rectangular slot. Angle’s edgewise appliance received its name because the archwire was inserted at a 90-degree angle to the plane of insertion. -

Sheldon Friel Memorial Lecture, presented 13 June 2016 at the 92nd Congress of the European Orthodontic Society, Stockholm, Sweden. Summary Background and objectives: From the beginnings of modern orthodontics, questions have been raised about the extraction of healthy permanent teeth in order to correct malocclusions. A hundred years ago, orthodontic tooth extraction was debated with almost religious intensity by experts on either side of the issue. Sheldon Friel and his mentor Edward H. Angle both had much to say about this controversy. Today, after significant progress in orthodontic practice, similar arguments are being voiced between nonextraction expansionists and those who see the need for tooth extractions in some orthodontic patients. Furthermore, varying concepts of mechanical retention of -

The Effects of Elastic Size and Archwire Type on 3-Dimensional Force Systems When Using Class II Interarch Elastics
The Effects of Elastic Size and Archwire Type on 3-Dimensional Force Systems When Using Class II Interarch Elastics by Joseph Stanley A thesis submitted in partial fulfillment of the requirements for the degree of Master of Science Medical Sciences – Orthodontics University of Alberta ©Joseph Stanley, 2017 Abstract Objectives: An orthodontic simulator (OSIM) device was used to compare the force systems generated by class II elastics on a ½ cusp class II malocclusion using four combinations of two elastic types and two archwire types. Methods: 3-dimensional forces and moments due to class II elastics were measured individually for each tooth (7-7) using Damon Q brackets on the maxillary and mandibular arches. Four test groups (n=44) were compared, each of a different combination of two elastic types (3/16", 2oz and 4.5oz) and two archwire types (0.014" nickel titanium and 0.019" x 0.025" stainless steel). Results: Only the upper canines and lower first molars recorded clinically significant forces (0.3N) and moments (5Nmm). 2oz and 4.5oz class II elastics produced clinically significant vertical extrusive forces and horizontal forces along the archwire to normalize a class II malocclusion. Stainless steel archwire minimized the extrusive forces of the 4.5oz elastics compared to nickel titanium archwire Conclusions: 2oz and 4oz class II elastics produced clinically significant vertical extrusive forces and horizontal forces along the archwire. Archwire type had no effect on 2oz class II elastics whereas 0.019" x 0.025"stainless steel significantly reduced the vertical extrusive effects of the larger 4.5oz elastics. ii Dedication To Jennifer, this was a tag team effort. -

Coated and Uncoated Nickel-Titanium Archwires: Mechanical Property
COATED AND UNCOATED NICKEL-TITANIUM ARCHWIRES: MECHANICAL PROPERTY AND SURFACE TOPOGRAPHY RESPONSE TO A SIMULATED ORAL ENVIRONMENT WITH AND WITHOUT BRACKET-RELATED LOAD-DEFLECTION INDUCED STRESS A THESIS IN Oral and Craniofacial Sciences Presented to the Faculty of the University of Missouri-Kansas City in partial fulfillment of the requirements for the degree MASTER OF SCIENCE by KELCEY LOVELAND B.S., Utah State University, 2008 D.M.D., University of Nevada – Las Vegas, 2015 Kansas City, Missouri 2017 COATED AND UNCOATED NICKEL-TITANIUM ARCHWIRES: MECHANICAL PROPERTY AND SURFACE TOPOGRAPHY RESPONSE TO A SIMULATED ORAL ENVIRONMENT WITH AND WITHOUT BRACKET-RELATED LOAD DEFLECTION INDUCED STRESS Kelcey Loveland, DMD, Candidate for the Master of Science Degree University of Missouri-Kansas City, 2017 ABSTRACT 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. -

Still University Three learning objectives: • Describe common approaches for Class II correction; • Discuss clinical applications and biomechanical considerations of TADs and novel appliances; • Describe maxillary molar distalization relative to third molars Distalization of the maxillary dentition is necessary for non-extraction Class II treatment, but it is challenging to achieve bodily movement without extrusion of the molars. In such cases, the palatal approach might be the best answer for obtaining these results. Palatal bone thickness and density, and soft tissue thickness are usually able to support temporary anchorage devices (TADs) in adults and adolescents. In this lecture, various challenging cases will be presented where TADs and novel appliances were used, and treatment outcomes will be discussed.

Orthodontic Arch Wires

As esthetic wires are introduced, metallic wires will likely be replaced for most orthodontic applications. Wires are assessed by their properties like strength, stiffness, range, formability and weldability. As an ideal archwire has not yet been found, archwires should be selected within the context of their intended use during treatment. This article throws light on the different types of archwires available for orthodontic use. INTRODUCTION: The archwire has been an integral part of the orthodontic appliance, ever since Dr. Edward Angle placed the first appliance into the patient’s mouth. Archwires are designed to move teeth with light continuous forces. These forces may reduce the potential for patient discomfort, tissue hyalinization and undermining resorption. Archwire should behave elastically when a force is applied. To achieve this various archwires are available. Stainless Steel Wires: Stainless steel was first introduced by Dr. F.Hauptmeyer during the First World War at Krupp’s dental polyclinic in Germany for making the prosthesis. The refinement of the drawing process to form wires was invented in the late 1930s by ANGLE. -
SHELDON FRIEL MEMORIAL LECTURE 2007 Myths and Legends in Orthodontics*

Advance Access publication 15 September 2008 SHELDON FRIEL MEMORIAL LECTURE 2007 Myths and Legends in Orthodontics * Frans P.G.M. van der Linden Radboud University Nymegen, Netherlands SUMMARY Opinions and procedures, which are incorrect or invalid but continue to exist, are discussed. Eight seldomly criticised subjects have been selected which are relevant for the theory and practice of orthodontics. First, the idea that all individuals have or can reach an occlusion with contact between all opposing teeth is commented upon. Second, interest and preferences of editors and referees in the acceptance of manuscripts is clarifi ed and the neglecting of published information explained. Third, the reliability of conclusions drawn from lateral roentgenocephalograms is reviewed in regard of the accuracy of commonly used bony landmarks. Fourth, the interpretation of growth data concerning visual interpretation, error of the method and reliability of conclusions based on cephalometric data, is treated. Fifth, the need of lateral roentgenocephalograms and recently developed digital techniques for diagnostic purposes is evaluated. Sixth, the validity of facial orthopedics, and particularly its supposed contribution to the improvement of facial confi guration and beauty is analysed. Seventh, the idea that the increase of mandibular intercanine width is the cause of the occurrence of mandibular incisor irregularities after alignment by treatment is challenged. Eight, the usefulness of traditional removable retainers as the Hawley and “wrap-around ” appliance, is questioned and an approach and design, adapted to the change from banding to bonding of fi xed appliances, is presented.
