Abstract
Self-ligating orthodontic brackets with archwire retainers formed of materials exhibiting shape memory. Each bracket which includes a base from which extends two spaced and opposing pairs of tie wings each pair of which define an archwire guide slot therebetween. The retainers include at least one flange to retain an archwire within the archwire guide slot but which is yieldable to permit insertion and/or removal of the archwire relative to the archwire guide slots. Portions of the brackets and/or retainer may be coated to reduce friction between the archwire and the bracket and to promote aesthetics and overall bracket appearance.
