Effect of low intensity pulsed ultrasound on orthodontically induced root resorption caused by torque: A prospective double blinded controlled clinical trial
DownloadFall 2015
Orthodontically induced root resorption (OIIRR) is an undesirable consequence of orthodontic treatment and may lead to permanent loss of root structure. A previous clinical trial demonstrated the effect of LIPUS on tipping type of OTM and reported that LIPUS can promote cementogenesis. However,...

Fall 2018
Nanomechanical torque magnetometry is emerging as a highly-sensitive method for gauging magneto-statics and magnetic dynamics in mesoscopic and nano-scale magnetic materials. Advances in torque magnetometry are presented here, which were unattainable using previ- ous techniques. Silicon nitride...

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...

The effects of stainless steel ligature ties on the mechanical characteristics of conventional and self-ligated brackets subjected to torque
DownloadFall 2012
Stainless steel ligatures ties are routinely used by orthodontists to improve torque; nevertheless, there is a lack of evidence as to the role of stainless steel ligation in bracket retentive characteristics. The objective of this study is to look into the effects of stainless steel (SS) ligation...

Fall 2010
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...
