Abstract
Orthodontic force modules and assemblies for use in correcting class II and/or class III malocclusions include an elongate hollow outer body extending between proximal and distal ends, a plunger, spring, and push rod. The plunger and push rod are slidably received within different ends of the hollow outer body. The spring is positioned within the hollow outer body and provides an expansion force which provides a desired corrective force. The outer body, plunger, spring, and push rod can be configured in a telescoping relationship in order for the components to be telescopically compressed and expanded during use. The distal end can include a bendable pin or latch mechanism for attachment to a buccal tube. The push rod can include a hook, hole, or slot for attachment to an archwire. Various connectors for coupling an orthodontic force module to a buccal tube portion of a molar bracket are also disclosed.
