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...

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...

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...
