Investigation into the effects of stainless steel ligature ties on the mechanical characteristics of conventional and self-ligated brackets subjected to torque
Download2014
Heo, Giseon, Nobes, David S., Al Fakir, Hussam, Major, Paul W., Melenka, Garrett W., Carey, Jason P.
Objective: Torque is applied to orthodontic brackets in order to alter the buccal-lingual angulation of a tooth. One factor that can affect torque is the ligation mode used to retain the archwire in the bracket slot. The objective of this study was to investigate the effects of stainless steel...

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...
