ABSTRACT:
Orthodontic brackets are manufactured from at least one type of crystalline polymer that enhances the physical properties of the brackets. In one aspect, orthodontic brackets according to the invention may comprise at least one type of polyaryletherketone or crystalline polyamide. Fibers, fillers, flow additives and other components may be added as desired. One or more amorphous polymers may be blended with the crystalline polymer. Crystalline polymers are especially well-suited for the manufacture of self-ligating orthodontic brackets that include a bracket base and ligation cover so as to provide sufficient strength for the bracket base and ligation cover while also providing sufficient flexibility for the hinge element to bend or flex.
