Braces are used by orthodontists to correct the misalignment of teeth in the mouth. Archwire rotation is a particular procedure used to correct tooth inclination. Wire rotation can result in deformation to the orthodontic brackets, and an orthodontic torque simulator has been designed to examine this wire-bracket interaction. An optical technique has been employed to measure the deformation due...

A 3D mathematical model of orthodontic archwire with rectangular curve is established. Simplified 3D solid model of orthodontic archwire bending robot, which is consistent of bending die, support structure and archwire are established by Creo software, then the simplified model of bending die is put into ANSYS Workbench. Material parameters the contact condition and boundary conditions are set ...

This article is a presentation of a clinical methodology aimed at minimizing binding in fixed orthodontic appliances. The dynforce archwire is explained. The dynforce archwire has a full size anterior segment (e.g. .021×.025) and undersized posterior segments with rectangular cross-section (e.g. .018×.025 or .018×.022), and is used in the orthodontic phase of space closure with or without TAD m...

INTRODUCTION The orthodontic technique favored by a clinician frequently determines how a deep curve of Spee (COS) is leveled. The primary purpose of this investigation was to confirm radiographically the long-term effectiveness of a continuous archwire technique--the Alexander discipline--in leveling the COS in patients with Class II Division 1 deep-bite malocclusions treated without extractio...

OBJECTIVE We compared the skeletal and dental changes that resulted from the use of two methods of intermaxillary fixation (IMF)-miniscrews and surgical archwire-in 74 adult patients who had Class III malocclusion and were treated with the same orthognathic surgical procedure at a hospital in Korea. METHODS All the patients underwent Le Fort I osteotomy and bilateral sagittal split ramus oste...

Introduction: The aim of this study was to assess the galvanic behavior of different bracket and archwire combinations that are commonly used in orthodontic treatments. Methods: Three types of orthodontic archwires with a diameter of 0.016×0.022 inch and 80 standard edgewise maxillary central incisor brackets were selected. Three groups consisted of different wire-bracket couples and one group ...

Pain is a common patient complaint during the orthodontic movement of teeth, especially immediately following archwire placement. Vibration has been used to accelerate the orthodontic movement of teeth and some observations by clinicians have indicated that vibration appeared to reduce the pain of orthodontic treatment. The purpose of this parallel group, randomized clinical trial was to invest...

The purpose of this study was to analyze the relationship between the critical contact angle and the torque angle in an orthodontic bracket and archwire assembly in 3 dimensions. Three-dimensional mathematical models were created with geometric bracket-archwire parameters that included 2 slot sizes, 3 bracket widths, and 3 to 4 wire sizes. From this, 3-dimensional mathematical equations (3DMEs)...
