FEM Simulation of Non-Progressive Growth from Asymmetric Loading and Vicious Cycle Theory: Scoliosis Study Proof of Concept
Download2010
Fok, Jonathan W., Carey, Jason P., Adeeb, Samer
Scoliosis affects about 1-3% of the adolescent population, with 80% of cases being idiopathic. There is currently a lack of understanding regarding the biomechanics of scoliosis, current treatment methods can be further improved with a greater understanding of scoliosis growth patterns. The...

Sensitivity Analysis for Plane Orientation in Three-Dimensional Cephalometric Analysis based on Superimposition of Serial CBCT Images
Download2010
Major, Paul W., Lagravère, Manuel O., Carey, Jason P.
Objectives: The purpose of this study was to evaluate the potential errors associated with superimposition of serial cone beam CT (CBCT) images utilizing reference planes based on cranial base landmarks using a sensitivity analysis. Methods: CBCT images from 62 patients participating in a...

Measurement of orthodontic bracket tie wing elastic and plastic deformation by arch wire torque expression utilizing an optical image correlation technique
Download2010
Badawi, Hisham H., Homeniuk, Darren L.N., Lacoursiere, Ryan A., Carey, Jason P., Nobes, David S., Major, Paul W.
Orthodontic lingual root movement (torque) is an important aspect of treatment biomechanics and is typically achieved by torsion of a rectangular wire within the orthodontic bracket slot which introduces a force couple. The magnitude of the force moment achieved by wire torsion may be influenced...

Orthodontic bracket manufacturing tolerances and dimensional differences between select self-ligating brackets
Download2010
Nobes, David S., Carey, Jason P., Major, Paul W., Major, Thomas W.
In all manufacturing processes there are tolerances; however, orthodontic bracket manufacturers seldom state the slot dimensional tolerances. This experiment develops a novel method of analyzing slot profile dimensions using photographs of the slot. Five points are selected along each wall, and...

Micro-Scale Energy Dissipation Mechanisms During Fracture in Natural Polyphase Ceramic Blocks
Download2011
Vincent, Gregory, Boonsue, Suporn, Rogers, Robert, Spray, John, Schneider, Markus, Hogan, James
The dynamic fracture of natural polyphase ceramic (granite) blocks by high-speed impact at 207 m/s, 420 m/s and 537 m/s has been investigated. An electromagnetic railgun was used as the launch system. Results reveal that the number of fragments increases substantially, and the dominant length...

An investigation into the mechanical characteristics of select self-ligated brackets at a series of clinically relevant maximum torquing angles: Loading and unloading curves and bracket deformation
Download2011
Nobes, David S., Major, Paul W., Melenka, Garrett W., Major, Thomas, Carey, Jason P.
Edgewise orthodontic treatment utilizes a force couple in order to achieve labial–lingual tooth angulation. Two self-ligating brackets (Damon Q and Speed) were examined across a range of clinically relevant torques in order to assess the loading and unloading curves and bracket deformation. A...
