In-Vitro Evaluation of Frictional Resistance of three Different Aesthetic Self Ligating Brackets Using two Archwire Alloys
نویسندگان
چکیده
Aim: To estimate and compare the frictional forces engendered by three types of aestheticselfligating brackets with two straight wire alloys. Materials: The study comprised of a total of 90 brackets, of which 30 passive (Damon clear 2),30 active(GAC In-Ovation C) and 30 interactive (Empower clear) orthodontic brackets with a slot size of .022X.028 MBT prescription in combination with stainless steel(SS) and Titanium molybdenum alloy(TMA) wires of dimension 0.019X0.025inch.Frictional resistance was evaluated using Instron Universal testing machine and the results were tabulated.Results: passive aesthetic self-ligating brackets had least amount of friction when equated with active and interactive aesthetic self-ligating brackets with the use of either SS and TMA straight wires.Conclusion: The frictional resistance did not remain the same when tested with both the different types of rectangular straight wire alloys.All brackets showed higher frictional resistance when TMA rectangular straight wire alloy was used.

AIM The aim of this study was to compare frictional resistance which was produced between conventional brackets (0.022 slot Otho-Organiser) and self ligating brackets (active Forestadent and passive Damon III) by using various arch wire combinations (0.016 Niti, 0.018 Niti, 0.017 x 0.025 SS and 0.019 x 0.025 SS). METHODS An experimental model which consisted of 5 aligned stainless steel 0.022...
