Measurement Accuracy and Reliability of Tooth Length on Conventional and CBCT Reconstructed Panoramic Radiographs
Download2014
Flores-Mir, Carlos, Carey, Jason P., Rosenblatt, Mark R., Major, Paul W., Heo, Giseon
Introduction: This in vivo study assessed accuracy and reliability of tooth length measurements obtained from conventional panoramic radiographs and CBCT panoramic reconstructions to that of a digital caliper (gold standard). Methods: The sample consisted of subjects who had CBCT and conventional...

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...

Carey, Jason P., Melenka, Garrett W., Cheung, Benjamin K., Lepp, Eric
Two dimensional (2D) tubular braided composites consist of textile fibers imbedded in a resin matrix. Braid geometry and void content will affect the mechanical behavior of the tubular braided composite samples. In this study, tubular braid samples were assessed using micro X-ray computed...

Multi-Objective Optimization Framework for Landmark Measurement Error Correction in Three Dimensional Cephalometric Tomography
Download2013
Lagravère, Manuel O., Carey, Jason P., DeCesare, Alessandro, Secanell, Marc
The purpose of this study is to minimize errors that occur when using a four vs six landmark superimpositioning method in the cranial base to define the co-ordinate system. Cone beam CT volumetric data from ten patients were used for this study. Co-ordinate system transformations were performed....

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...
