摘要： An archwire used during the course of orthodontic treatment has four generally flat sides that are arranged in the general shape of a rectangle. The four sides are connected by curved surfaces having a radius of curvature that is substantially larger than the corners of conventional archwires. The cross-sectional shape of the archwire facilitates insertion and removal of the archwire in orthodontic appliances such as brackets and also tends to reduce resistance to sliding movement of the appliances along the archwire.
