Abstract
Orthodontic force modules for use in correcting class II and/or class III malocclusions. In one embodiment, the force module (100) includes an elongate body (102) extending between a distal end (104) and a proximal end (106), a movable member (108) extending between a proximal end (112) and a distal end (110) that is slidably disposed relative to the elongate body (102), a movable piston (108) disposed at or near the distal end (110) of the movable member, a stop (118) disposed at or near a proximal end (106) of the elongate body (102) and proximal to the movable piston (108), and an elastomeric member (120). A proximal end (112) of the elastomeric member (120) is cooperatively coupled to the stop (118), while a distal end (110) is cooperatively coupled to the movable piston (108) so that when the movable member is moved distally relative to the body, the elastomeric member (120) stretches so as to apply a counter-force to the movable member (108).
