Title:

A FORCE GENERATING DEVICE USEFUL IN ORTHODONTIC APPLIANCES

Document Type and Number:

WIPO Patent Application WO1999059494

Kind Code:

A9

Abstract:

A force generating device is described which includes an elastomeric force generating member (10). Preferably the elastomeric member (10) is an elastomeric polymer tube (24). Each end of the tube (24) can be fitted over collars (16, 18). Attached to one collar is a piston (20), and formed within the other collar (16) is an orifice (22) for slidably receiving the piston (20). 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.
