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...

The effect of wire alloy on torque expression in metallic self-ligating orthodontic brackets
DownloadFall 2009
The objective of this thesis was to identify differences in torque expression between three brands of metallic self-ligating brackets with stainless steel, TMA® and CuNiTi® wire and to compare active and passive designs. 150 of each Damon-3MX (Ormco Inc, Orange, CA, USA), SPEED (Strite...

Deformation of the orthodontic bracket upon wire engagement may result in torque dissipation within the bracket rather than transmission to the tooth and its supporting structures. The purpose of this study was: 1) quantify the amount of torque expression and 2) quantify any deformation as a...

Two and three dimensional cephalometric assessment of dental and skeletal changes following orthodontic treatment with Damon passive self-ligating system
DownloadSpring 2010
Objectives: The aim of this study was to evaluate dental and/or skeletal changes following orthodontic treatment with Damon self-ligating (SL) brackets in non-extraction patients. Methods: Frontal and lateral cephalomteric radiographs of 20 patients before and after non-extraction treatment with...
