title: A comparison of the frictional characteristics of five initial alignment wires and stainless steel brackets at three bracket to wire angulations--an in vitro study.
abstract: The study investigated static planar frictional resistance between five initial alignment wires and stainless steel brackets at three bracket to wire angulations (0, 5 and 10 degrees). It was demonstrated that static frictional resistance increased significantly with increasing bracket to wire angulation due to binding within the system. Epoxy-coated steel had the highest static frictional resistance and coaxial stainless steel the lowest. Fibre-optic glass (Optiflex) had low frictional resistance. The coefficient of friction followed the trends of static frictional resistance in all respects.
