The Effect Of Orthodontic Appliances On The Evaluation Of The Professionalism And Esthetics Of An Adult Employee, Laura Hanson Vaccariello
The Effect Of Orthodontic Appliances On The Evaluation Of The Professionalism And Esthetics Of An Adult Employee, Laura Hanson Vaccariello
Master's Theses (2009 -)
This study explored the influence of fixed and removable orthodontic appliances on participants’ ratings of the job performance, intelligence, and attractiveness of an adult female. Ninety-four adult subjects were recruited from the Graduate School of Management at Marquette University. Each subject received an identical employee performance review with an attached photograph of a female employee. The smile of the photo was manipulated to represent one of four conditions: no orthodontic appliance, a metal orthodontic appliance, a ceramic orthodontic appliance, or a clear aligner. Subjects then rated the employee on three continuous Likert scales. Ratings of job performance, intelligence, and attractiveness …
Mechanical Properties Of Copper-Nickel-Titanium Archwires, Margaret Amelia Rosen
Mechanical Properties Of Copper-Nickel-Titanium Archwires, Margaret Amelia Rosen
Master's Theses (2009 -)
Introduction: The initial phase of orthodontic therapy relies on flexible wires, usually composed of a nickel-titanium alloy, to apply a substantially constant load during tooth movement. Copper has been added to nickel-titanium archwires, resulting in an alloy with potential clinical advantages such as a lower stress hysteresis. Many orthodontic companies claim that their copper-nickel-titanium manufacturing process allows for the production of more consistent transition temperatures in the wires, allowing the orthodontist to customize treatment to various patients based on the force level needed. There are currently many manufacturers of these wires, creating a wide range of copper-nickel-titanium archwires from which …
Thermal Properties Of Copper Nickel-Titanium Orthodontic Archwires, Joshua Gilbert
Thermal Properties Of Copper Nickel-Titanium Orthodontic Archwires, Joshua Gilbert
Master's Theses (2009 -)
Introduction: Copper Nickel-Titanium (CuNiTi) is a relatively new composition of Nickel-Titanium (NiTi) archwires that was originally patented in 1991 as part of the Ormco line of wires. The patent has now recently expired and many other orthodontic companies are making their own CuNiTi wires. Advertisement claims have focused on the laboratory benefits of adding Copper (Cu) to the NiTi, however few independent laboratory testings have been conducted on these new wires to verify claims. The purpose of this study was to conduct thermal analysis of CuNiTi for all currently available wires in two Austenite Finish (Af) variants and two commonly …
