Abstract: An improved force module is used in orthodontic applications for treating patients with overbite or other dental problems. The improved force module may act as a force limiter to limit movement of a pushrod attached to either an archwire or bow and thereby limit a force generated by a spring attached to the pushrod. The improved force module is designed for use in an orthodontic system which self-adjusts, thus eliminating the need for routine adjustment. Also, the improved force module maintains its shape and strength for several months, may be made from a shape memory polymer, and may contain an embedded reinforcing wire or fiber.
