Abstract
Aims: To compare the frictional coefficients between the stainless steel and B–titanium arch wire liga-tured to the stainless steel bracket via different ligatures. Materials and Methods: The sample of the study included the stainless steel and β–Titanium arch wire groups, the wire group comprised of three subgroups, each wire subgroup ligatured to stainless steel brackets via different ligatures. The mea-surement of the frictional coefficient was performed using the simulated side arch fixed appliance at-tached to the tensile machine. The data were analyzed by using the descriptive and variance statistical tests at p≤ 0.05 significance level. Results: The results demonstrated that the stainless steel arch wire tied to the bracket via stainless steel ligature achieved significant lower frictional coefficient value when compared with other wire subgroups. Conclusions: The combination of the stainless steel; arch wire, bracket and ligature is more practical choice in sliding orthodontic treatments.
