A new esthetic fiber-reinforced polymer composite resin archwire: a comparative atomic force microscope (AFM) and field-emission scanning electron microscope (FESEM) study

Progress in Orthodontics

Table 2 Orthodontic archwires used in the study

Wire	Wire size (in.) and brand	Composition	Manufacturer
Translucent composite	0.018	Mixture of cured copolymers, Bis-EMA, TEGDMA, and glass fibers	BioMers Products LLC, Naples, FL, USA
Nickel titanium	0.018	52% Ni, 45% Ti, and 3% Co	International Orthodontic Services Inc., Houston, TX, USA

Wires of 0.018-in. dimension were studied for friction and roughness with various archwire-bracket combinations. Bis-EMA, ethoxylated bisphenol A glycol dimethacrylate; TEGDMA, triethylene glycol dimethacrylate.
