Abstract
The temporomandibular joint (TMJ) is unique joint formed by the squamous portion of the temporal bone and the condyle of the mandible. The TMJ forms two synovial joints which are structurally supported by the mandibular condyle, joint capsule, an articular disc and supporting ligaments. The main arterial components of this region are branches of the maxillary artery and terminal branches of the external carotid artery while the venous drainage is by way of the superficial temporal vein, pterygoid plexus and maxillary vein. Sensory innervation is supplied by the mandibular division of the trigeminal nerve (V3). This is a very compact space with various vessels, ligaments and muscles. The TMJ is a location of unique movements and structures which are often difficult to visualize for dental students. The purpose of this presentation was to develop an educational video to supplement other resources when studying the TMJ. The Planmeca Promax 3D Mid Cone Beam Computed Tomography (CBCT) was used to demonstrate coronal, sagittal and axial planes of TMJ structures. To view and capture CBCT images the InVivoDental Viewer 5.1 was used. Dry skull specimens, Netters Head and Neck Anatomy textbook illustrations and cadaver dissections were used to create a multimedia resource to facilitate dental students understanding of the TMJ. Panopto video software and a 4th Generation iPad pro 12MP camera were used to combine various visual aids into a single educational resource. Utilizing this educational resource will assist dental students to learn the unique movements and relationships of the TMJ more efficiently.
