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...

Craster, R. V., Flynn, M.R., Bhattacharya, S.
By adapting the Föppl-von Kàrmàn equation, which describes the deformation of a thin elastic membrane, we present an analysis of the buckling pattern of a thin, very viscous fluid layer subject to shear in an axisymmetric geometry. A linear stability analysis yields a differential eigenvalue...

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...

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...

Plamondon, Carson, Bessa, Guilherme M., Nobes, David S.
This paper outlines the design of an unsteady flowmeter for ex-vivo heart perfusion applications. In order to determine the performance of a given heart, the flowrate in the system must be recorded. The proposed design is based on an orifice plate flowmeter comprising three pressure transducers...

Numerical Simulation of Ballistic Impact of 20 mm Fragment Simulating Projectiles (FSPs) into Ultra-High Molecular Weight Polyethylene (UHMW-PE) Targets
Download2022-06-01
Khanna, Kshitiz, Jensen, Morten Rikard
Composite materials are widely used in the defense and aerospace industry because of their light weight and high strength properties. Ultra-high molecular weight polyethylene (UHMW-PE) is commonly used in the design of various types of armor from vehicle applications to personal protective...
