Pin connector for orthodontic force module

An orthodontic force module assembly for correcting Class II and/or Class III malocclusions, comprising:

• an orthodontic force module having a proximal end and a distal end;
• and
• a pin connector extending from the distal end of the orthodontic force module and configured for attachment of the orthodontic force module to an orthodontic buccal tube or other orthodontic appliance, the pin connector being comprised of:
• an elongate pin body extending between a proximal end and a distal end and having a region of reduced cross-sectional diameter compared to a cross-sectional diameter of at least one adjacent region, the region of reduced cross-sectional diameter causing the elongate pin body to preferentially bend in the region of reduced cross-sectional diameter and not in an adjacent region when attaching the pin connector to an orthodontic buccal tube or other orthodontic appliance;
• and
• an extension rod interconnecting the proximal end of the pin body to the distal end of the orthodontic force module.

A method of attaching an orthodontic force module to an orthodontic buccal tube or other orthodontic appliance, comprising:

• providing an orthodontic force module with a pin connector at an end thereof;
• inserting an elongate pin body of the pin connector into a tunnel of the orthodontic buccal tube or other orthodontic appliance;
• and
• bending a portion of the elongate pin body in order to secure the pin connector to the orthodontic buccal tube or other orthodontic appliance,
• the elongate pin body preferentially bending in a predetermined region as a result of the predetermined region having a reduced cross-sectional diameter compared to a cross-sectional diameter of at least one adjacent region.
