The objective of this study is to analyze a set of previously developed and proposed image segmentation protocols for precision in both intra- and inter-rater reliability for in vivo tooth volume measurements using cone-beam computed tomography (CBCT) images. Six 3D volume segmentation procedures...

The Effect of Conventional Elastomers on Force and Moment of a Self-Ligating Orthodontic Bracket with Second-Order Angulation in the Dry and Wet States evaluated through a new 3D Friction Device
DownloadSpring 2013
Objective: A new three-dimensional friction device was used to investigate the effect of conventional elastomers on force and moment of a self-ligating orthodontic bracket with second-order angulation during a simulated retraction. Methods: An 0.018x0.025-in stainless steel archwire was drawn...

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...

Using two- and three-dimensional kinematic analysis to compare functional outcomes in patients who have undergone facial reanimation surgery
DownloadFall 2010
The current study was designed to: (1) compare the sensitivity of a 2-dimensional video-based system with a 3-dimensional optical system, and (2) investigate movement on the affected and unaffected side of the face during the production of various functional movement tasks in 5 patients who had...
