A comparative study of frictional resistance of stainless steel, nickel titanium, TMA, timolium & CNA archwires with stainless steel brackets - An in vitro study .
Objective: To compare the amount of expressed frictional resistance between orthodontic self-ligating brackets and conventionally ligated brackets in vitro as reported in the literature. Methods: S...
This paper presents a new friction coefficient of flat plate in wide Raynols number range. The main purpose of this study is to present a verification data for CFD calculation, which will be applied t...
In order to clarify correlation between properties of coating on ship hull surfaces and frictional resistance, experimental studies were carried out. A rotating cylinder type dynamometer was newly dev...
Orthodontic sliding mechanics using preadjusted brackets is a popular approach for achieving incisor retraction. A distally directed force slides the archwire through brackets and tubes in the buc...
The frictional behavior of four conventional and four self-ligating brackets were simulated using a mechanical testing machine. Analyses of the two-bracket types were completed by drawing samples of...
