II III ORTHODONTIC FORCE MODULE FOR CLASSES II AND III CORRECTION

摘要

Orthodontic force modules and assemblies for use in correcting Class II and / or Class III malocclusions include an elongated hollow outer body, a plunger, a spring, and a push rod extending between the proximal and distal ends. . The plunger and push rod are slidably received within different ends of the hollow outer body. The spring is disposed within the hollow outer body, and during use, when the force module or assembly is compressed (eg, when closing the jaw), it provides an extension force. The extended force provides the desired corrective force for correcting Class II and / or Class III malocclusions. The outer body, plunger, spring and push bar can be configured in an interaxial relationship to allow the component to be compressed and extended in an interaxial manner during use. The distal end can include a bendable pin or latch mechanism for attachment to the buccal tube. The push bar can include a hook, hole, or slot for attachment to the arch wire. Various connections are also disclosed for coupling the orthodontic force module to the buccal canal portion of the molar bracket.
