Improved Dental Articulator

Project Summary

A dental articulator is a mechanical hinged tool used by doctors, dentists, and orthodontists to map a patient’s bite position. Traditional articulators fix the lower dental arch and limit movement in multiple directions, making them unsuitable for orthodontic treatments. Our device improves articulation, allowing more dynamic and precise jaw movement that mimics the human jaw. iciency.

Design Goal

Create an advanced physical simulation of temporomandibular joints and accurate jaw function.

Design Constraints

• At least three degrees of freedom on the lower arch.
• Model the adult jaw motions:
  - Anterior and posterior translation (forward and backward)
  - Pitch (open and close)
  - Yaw (rotational side to side)
• Model the adult jaw in weight and forces in the gravitational direction.
• Customizable to model a variety of patients
