Frictional resistance of esthetic-coated archwires in with metal, ceramic and polycarbonate brackets

The level of friction that occurs when aesthetic brackets interact with coated wires is of interest. The resistance values reached their minimum point when stainless steel brackets used coated NiTi wires at 2.3 ± 0.2 N but reached their maximum point when ceramic brackets applied ceramic-coated NiTi wires at 6.5 ± 0.5 N. Brackets made with stainless steel material combined with coated NiTi wires produce superior orthodontic results according to the research. The increased friction caused by ceramic brackets could possibly reduce the rate of tooth movement. The decision of proper wire-bracket pairs remains critical because it determines both therapy results and cosmetic outcomes.
