    Study Notes

    Temporomandibular Joint (TMJ) and Mandibular Movements

    • The maxillomandibular relationship where the condyles articulate with the thinnest avascular portion of their respective articular disks is called centric relation.
    • Lateral movement of the mandible in the horizontal plane is controlled by the medial pterygoid muscle.
    • In an ideal orthodontic relationship, the anterior teeth overlap both horizontally and vertically by 2mm.
    • The stylomandibular ligament attaches the body of the mandible to the base of the skull.
    • The temporomandibular ligaments play a role in limiting excessive movements of the mandible.
    • The primary function of the articular disk in the TMJ is to reduce friction and distribute stress.
    • The retrodiscal pad in the TMJ serves to cushion and reduce stress.
    • Movement in space can be divided into translation and rotation components.

    Mandibular Movements

    • Mandibular movements can be described in three planes: sagittal, frontal, and horizontal.
    • The components of mandibular movement can be described in terms of rotation and translation.
    • In the sagittal plane, the mandible is capable of a purely rotational movement, as well as translation.
    • In the horizontal plane, the mandible is capable of rotation around several vertical axes.
    • Lateral movement consists of rotation around an axis situated in the working (laterotrusive) condylar process with relatively little concurrent translation.

    Occlusion and Restorative Procedures

    • Ensuring uniform dental contact on closing is important to allow optimal function.
    • Malocclusion may be associated with undesirable changes to the teeth, periodontium, and TMJ.
    • The concept of ideal versus pathologic occlusion is introduced in the study of occlusion.
    • Restorative procedures affect the shape of the occlusal surfaces.

    Anatomic Structures

    • The articular disk consists of avascular dense connective tissue.
    • The body of the mandible is attached to the base of the skull by muscles and three paired ligaments: temporomandibular ligaments, Sphenomandibular ligaments, and stylomandibular ligaments.
    • Several muscles are responsible for mandibular movements, including muscles of mastication and suprahyoid muscles.
