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...

Review of Maxillary expansion appliance activation methods: engineering and clinical perspectives
Download2010
Lagravère, Manuel O., Carey, Jason P., Romanyk, Dan L., Major, Paul W., Toogood, Roger W.
Objective. Review the reported activation methods of maxillary expansion devices for midpalatal suture separation from an engineering perspective and suggest areas of improvement. Materials and Methods. A literature search of Scopus and PubMed was used to determine current expansion methods. A...

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...

Fahimi, Farbod, Dawson, Michael R., Carey, Jason P.
The objective of above-elbow myoelectric prostheses is to reestablish the functionality of missing limbs and increase the quality of life of amputees. By using electromyography (EMG) electrodes attached to the surface of the skin, amputees are able to control motors in myoelectric prostheses by...

The effect of perturbations on resistance to sliding in second order moments comparing two different bracket types
Download2014
Wong, Justin W., Carey, Jason P., Romanyk, Dan L., Heo, Giseon, Toogood, Roger W., Major, Paul W.
Orthodontic literature has shown all ligation methods to behave similarly in the clinical situation; however, the reasoning behind this still requires further investigation. A novel frictional device able to measure forces at the level of the bracket along with a custom perturbation device was...

The Effect on Elastic Modulus of Rigid-Matrix Tubular Composite Braid Radius and Braid Angle Change Under Tensile Loading
Download2013
Melenka, Garrett W., Leung, Cheequn K., Nobes, David S., Carey, Jason P.
The objective of this paper is to assess changes in braid radius and braid angle of braided composite tubes under tensile loading using stereomicroscope digital image correlation (DIC) based optical measurement techniques. Using this approach, displacement fields were calculated and three...

Carey, Jason P., Melenka, Garrett W., Nobes, David S., Major, Paul W.
Archwire rotation is used in orthodontic treatment to alter the labiolingual orientation of a tooth. Measurement of the 3-dimensional (3D) motion of the orthodontic brackets requires a new configuration of the orthodontic torque simulator. The orthodontic torque simulator was coupled with a...

Nobes, David S., Major, Paul W., Melenka, Garrett W., Carey, Jason P.
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...

Validation of a Numerical Model for Reciprocating Thermodynamic Machines by Examining Heat Transfer in a Low Temperature Difference Stirling Engine
Download2022-06-01
Lottmann, Matthias, Nobes, David S.
A third order two-dimensional numerical model for reciprocating thermodynamic machines is validated using a low temperature difference Stirling engine with 15 Watt shaft power and source and sink temperatures of 150 °C and 5 °C. The work is limited to the thermodynamic model at steady state. The...
