Comparison of Frictional Resistance of Teflon-coated Stainless Steel and Stainless Steel Wires Ligated with Various Types of Ligature in Ceramic Brackets

The aim of the study was to compare frictional resistance of stainless steel (SS) and Teflon-coated SS wires ligated with various types of ligature in ceramic brackets. Six combinations of specimens, comprising two types of 0.019x0.025-inch main archwire, SS and Teflon-coated SS wires, and three types of ligation, elastomeric, SS and Teflon-coated SS ligatures were used in 0.022x0.028-inch ceramic brackets, 10 samples for each group. The frictional resistance of each combination was measured using a universal testing machine. The means of maximum static frictional resistance were compared according to types of wire and ligature using Two-way ANOVA followed by Dunnett's T3 post-hoc test (p<0.05).

The results showed that the frictional resistance of Teflon-coated SS wires (58.6±35.1 g) was not significantly different from that of SS wires (68.8±48.4 g) regardless of the ligature type. The frictional resistance of elastomeric ligatures (108.5±40.7 g) was statistically significantly greater than that of SS ligatures (32.7±17.1 g) and Teflon-coated SS ligatures (50.0±16.0 g) (p<0.001), whereas the frictional resistance of Teflon-coated SS ligatures was statistically significantly greater than that of SS ligatures regardless of the wire type (p<0.01).

In conclusion, the frictional resistance of Teflon-coated SS and SS wires were not significantly different when used in the ceramic brackets regardless of the ligature type.
