Abstract
A permanently mounted orthodontic intermaxillary constant force system wherein the force producing portions are attached to the orthodontic appliance in one jaw and small flexible cables transmit the forces to the patient's opposite jaw.
Claims19
An intermaxillary force system for applying permanent intermaxillary forces during orthodontic treatment comprising:
- a hollow longitudinal tube having a first and second end, a wall with an outer and inner circumference wherein the tube is attached to an orthodontic appliance to be positioned within a single jaw;
- a force producing means within the tube for producing tooth movement;
- a flexible cable connected to the internal force producing means wherein the cable exits the tube at the first end and is attached to the orthodontic appliance to be positioned in the opposite jaw for producing tooth movement pressure between the jaws;
- an attaching means for securing the horizontal tube to the orthodontic appliance.

An intermaxillary force system for applying permanent intermaxillary force during orthodontic treatment comprising:
- a longitudinal thin walled tube with first and second ends, a length sufficient to extend from a patient's molars to the incisors, an opening in the wall of the tube near the first end;
- a coiled longitudinal spring within the tube;
- a grooved pulley at the first end of the tube adjacent to the lateral opening;
- and
- a cable attached to the spring wherein the cable enters the pulley groove and exits the tube through the adjacent lateral opening and is attached at a point on the orthodontic appliance of the opposite dental arch.
2 more elements
An intermaxillary force system comprising:
- a hollow longitudinal tube containing a system capable of producing a pulling force;
- a cable system attached to the pulling force system for translating the force to a point in the opposite jaw;
- and
- a mounted C shaped clasp system attached to the hollow longitudinal tube wherein the C shaped clasp is attached to an orthodontic appliance thereby attaching the hollow longitudinal tube to an orthodontic appliance.
