The aim was to assess the composition of released metal ions from fixed orthodontic appliances both in an vitro and vivo setting compare their quantities evaluate any possible health risks associated with them. For setting, a set 24 as-received sterile SS brackets, 2 archwires, NiTi archwires were aged for 90 days artificial saliva, ion concentrations determined by inductively coupled plasma ma...

objectives: the aim of this study was to assess and compare the characteristics of commonly used initial archwires by their load deflection graphs. materials and methods : this study tested three wire designs namely copper nickel titanium (cnt), nickel titanium (niti), and multi-strand niti (msnt) archwires engaged in passive self-ligating (psl) brackets, active self-ligating (asl) brackets or ...

Abstract Reducing the friction force between commercial archwire and bracket during orthodontic treatment in general dental practice has attracted worldwide interest. An investigation on wear behaviors of uncoated carbon film coated stainless steel archwires running against brackets was systematically conducted. The films were prepared at substrate bias voltages from +5 to +50 V using an electr...

BACKGROUND Friction between archwires and brackets is assuming greater importance for finishing with increased use of sliding mechanics in orthodontics as friction impedes the desired tooth movement. The following study is conducted to compare and evaluate the effect of ligation on friction in sliding mechanics using 0.022" slot bracket in dry condition. MATERIALS & METHODS In the study 48 co...

OBJECTIVE To investigate and compare the effects of superelastic nickel-titanium and multistranded stainless steel archwires on pain during the initial phase of orthodontic treatment. DESIGN A double-blind two-arm parallel design stratified randomized clinical trial. SETTING A single centre in India between December 2010 and June 2012. A total of 96 participants (48 male and 48 females; 14....
