• The purpose of this study was to clarify the surface roughness of 31 brands of titanium alloy orthodontic wires from 13 manufacturers using a confocal optical microscope. Cobalt-chrome and stainless steel wire were also examined as a reference of comparison. The following results were obtained ; (1) Mean Ra, as determined from the lengthway axis of titanium alloy wires, was 0.296μm, and that determined from the widthway axis was 0.440μm. The modulus of Ra was 0.368μm. (2) For titanium alloy orthodontic wires, the greatest amount of modulus of Ra was 1.244μm and the lowest was 0.135μm. (3) Modulus of Ra was 0.140μm for the cobalt-chrome wire and 0.154μm for the stainless steel wire, each lower tendency than titanium alloy. As a result of our findings, we consider it necessary to select the smoother wire possible when using a sliding mechanism, if the mechanical properties of available wires are nearly the same.
