Temporomandibular joint dysfunction (TMD) affects approximately 60–70% of the U.S. population, but the precise mechanisms underlying the causes of TMD are not well understood. To contribute to a better understanding of the possible biomechanical causes of TMD, a 3D model that can be manipulated to simulate different positions and postures, which may adversely affect the TMJ, was developed. To create such a 3D model, donated x‐ray CT data of the head, neck, and shoulders of an adult male of unknown etiology was analyzed using the visualization software program Avizo 9 ® . The skull, mandible, and cervical vertebrae were then manually segmented (i.e., marked) as independent entities. The resulting segmented structural 3D model was transferred to the software animation program Maya 2017 ® and subjected to character rigging so that the skull, mandible, and neck could be individually moved into various positions. This animated dynamic 3D model allows the study of various positions and body postures and their effects on the TMJ (e.g., a forward head posture and its effects on the forces acting on the TMJ) without having to resort to clinical observations with their ethically dictated limitations.
