Characterization of Esthetic Orthodontic Wires Made from Glass-Fiber-Reinforced Thermoplastic Containing High-Strength, Small-Diameter Glass Fibers

Table 3

Frictional forces of GFRTP wires against brackets.

Sample	Frictional force (N)
GFRTP-13	3.62 ± 0.33^a
GFRTP-7	3.86 ± 0.21^b
GFRTP-5	4.73 ± 0.28^a,b

Mean values with the same superscripts are significantly different from each other ().
