Effect Of Mechanical Vibration On Resistance To Sliding In The Fixed Orthodontic Appliance, David Robert Kennedy
Master's Theses (2009 -)
Objective: To determine the effects of mechanical vibrations produced from electric tooth brushes and a commercially available device called AcceleDent, on the resistance to sliding at the bracket-arch wire interface. Materials and Methods: All as-received wires and brackets were cleaned with 95% ethanol prior to testing. An individual metal bracket was mounted on a custom metal fixture.
