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...

Comparison of Deformation and Torque Expression of the Orthos and Orthos Ti Bracket Systems
Download2011
Major, Paul W., Melenka, Garrett W., Carey, Jason P., Nobes, David S., Heo, Giseon, Lacoursiere, Ryan A.
Orthodontic torque expression is the result of axial rotation of rectangular archwires within a rectangular bracket slot. This study investigates the effect of bracket material on torque expression. Torque exerted by a rotating archwire on each bracket will be measured as well as the relative...

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...
