Figure 6From: A new esthetic fiber-reinforced polymer composite resin archwire: a comparative atomic force microscope (AFM) and field-emission scanning electron microscope (FESEM) study Image showing surface roughness analysis of NiTi wire of NiTi-ICE group. NiTi wire showed roughness with Ra = 256.88 nm, RMS = 301.68 nm, and surface area difference of 5.42% (original magnification ×40 40 μm).Back to article page
