ABSTRACT:
An orthodontic archwire with a certain cross-sectional construction has a stiffness that is less than conventional archwires having identical overall dimensions. The archwire has four corner edge portions that provide control over torquing movements and uprighting movements of the associated teeth as may be needed during the course of orthodontic treatment. The archwire is particularly useful during the early stages of orthodontic treatment when an archwire of reduced stiffness is desired and yet control over torquing and uprighting movements of the associated teeth is sought. Optionally, the archwire includes an aesthetic coating with certain characteristics that enable the majority of the coating to remain intact and provide an improved overall appearance even if certain regions of the coating are damaged and removed.
