Area of Science:

  • Biomechanical Engineering
  • Medical Simulation
  • Human Anatomy

Background:

  • The temporomandibular joint (jaw) is complex, with challenging sliding and gliding movements.
  • Current understanding relies on mechanical simulations, lacking comprehensive computer models.
  • A need exists for a virtual jaw model to assist in medical diagnoses and surgical planning.

Purpose of the Study:

  • To present a 3D simulation of the human mastication apparatus.
  • To provide a tool for preoperative planning of craniofacial surgeries.
  • To enhance the education of dentists and surgeons regarding jaw anatomy and function.

Main Methods:

  • Development of a 3D computer model of the human jaw.
  • Implementation of a kinematic model to define articulation constraints.
