Abstract
A force generating device is described which includes an elastomeric force generating member. Preferably the elastomeric member is a elastomeric polymer tube. Each end of the tube can be fitted over collars. Attached to one collar is a piston and formed within the other collar is an orifice for slidably receiving the piston. When compressed, the force generating device will attempt to return to its original undeformed shape thus exerting a force along a longitudinal axis. Preferably, the force generating device is employed in an orthodontic assembly. For example, the force generating device can be employed in an orthodontic assembly for developing a patient's arch.
