Abstract: Force modules and assemblies for use in orthodontic corrections include an elongate hollow outer body extending between proximal and distal ends, a plunger, biasing member (e.g. spring), and push rod. The plunger and push rod are slidably received within different ends of the hollow outer body. The biasing member is positioned within the hollow outer body and provides an expansion force, which provides a desired corrective force. The outer body, plunger, biasing member, 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.

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 spring is positioned within the hollow outer body and provides an expansion force which provides a desired corrective force.

Abstract: A pin connector for attaching an orthodontic force module to an orthodontic appliance is configured to preferentially bend in a middle segment along an elongate pin body of the pin connector. The pin connector includes an elongate pin body and an extension rod extending laterally from an end of the pin body for interconnecting the pin body and an orthodontic force module. The elongate pin body includes first, second and third segments, with the second segment having reduced cross-sectional diameter relative to the first and third segments so that pin body preferentially bends in the second segment rather than the first and third segments when attaching the orthodontic force module to the orthodontic appliance. This provides a preselected amount of distance or play between the orthodontic force module and the orthodontic appliance.

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 during use as the force modules or assemblies is compressed (e.g., when closing the jaw). The expansion force provides a desired corrective force for corrective Class II and/or III malocclusions. 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.
