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.
