“…These results fully agree with those of most previous studies. (9)(10)(11) This is because of the absence of the ligation force from the elastic ligatures when the slide restrained the archwire. (12) In the present investigation passive self-ligating brackets produced significantly lower frictional force than active selfligating brackets when coupled with rectangular wires.…”

Aims: This study was aimed to compare static frictional forces generated by 3 types of brackets (conventional, active self-ligating and passive self-ligating) combined with 3 different sizes of stainless steel wire. Material and Methods: The sample consisted of three types of brackets (Equilibrium 2, Empower, discovery sl) with a slot size 0.022 inch were coupled with 0.020, 0.018×0.025 and 0.019×0.025 inches stainless steel wires, The testing model consists of 6 brackets used to represent lower anterior teeth. Ten tests were carried out for each group of bracket-wire combination in dry state, frictional force were measured by tensile testing machine. A significant P value of 0.05 was predetermined. Results: self-ligating brackets produced significantly lower value (P ≤0.05) of mean of static friction than elastomerically tied conventional bracket. The frictional force increased proportionally to the wire size. Conclusions:The method of ligation appears to be the primary variable responsible for the frictional resistance generated by these types of brackets.

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). Materials and Methods:An experimental model which consisted of 5 aligned stainless steel 0.022-in brackets was used to assess frictional forces which were produced by SLBs (self ligating brackets) and CELs (conventional elastomeric ligatures) with use of 0.016 nickel titanium, 0.018 nickel titanium, 0.017 x 0.025"stainless steel and 0.019 X 0.025"stainless steel wires.Statistical Analysis: One way ANOVA test was used to study the effect of the bracket type, wire alloy and section on frictional resistance test .Results: Conventional brackets produced highest levels of friction for all bracket/archwire combinations. Both Damon III and Forestadent brackets were found to produce significantly lower levels of friction when they were compared with elastomerically tied conventional brackets. Conclusion:SLBs are valid alternatives for low friction during sliding mechanics.
