The temporomandibular joint (TMJ), or jaw joint, is a synovial joint that allows the complex movements necessary for life. It is the joint between condylar head of the mandible and the mandibular fossa of the temporal bone.

Dec 24, 2024 · TMJ disorders — a type of temporomandibular disorder or TMD — can cause pain in the jaw joint and in the muscles that control jaw movement. The exact cause of TMJ disorder is often hard to determine.

Oct 30, 2023 · This joint allows a range of movements of the lower jaw, namely translational movements (protrusion/retraction and lateral deviation) and rotational movements (elevation/depression). This article will discuss the anatomy and function of the temporomandibular joint.

Jan 19, 2023 · The temporomandibular joint (TMJ) is formed by the articulation of the mandible and the temporal bone of the cranium. It allows opening, closing, and a side to side movement of the mouth. The TMJ is found anteriorly to the tragus of the ear, on the lateral aspects of the face.

Jan 8, 2015 · Mandibular movement is limited by the ligaments and the articular surfaces of the TMJs as well as by the morphology and alignment of the teeth. When the mandible moves through the outer range of motion, reproducible describable …

The temporomandibular joint (TMJ) is involved in mastication (chewing) and speech and it is one of the most frequently moved joints in humans. [1] . This synovial joint must be able to respond to significant biomechanical load. [2] . It is made up of the articulating surface of the temporal bone and the head of the mandible.

Jun 5, 2021 · There are primarily 6 types of mandibular movement, including opening, closing, rightward jaw translation, leftward jaw translation, protrusion, and retrusion. Variability in jaw movement allows for mastication of different textures and consistencies.

The condyles work together to achieve lateral movements of the jaw. When assessing lateral movement, it is necessary to differentiate one condyle from the other: The "working side" is the side that moves laterally when taking the chin as a reference; The "non-working side" is the side that moves towards the midline

Jul 17, 2023 · These structures are the temporomandibular joint (TMJ), jaw and mandible, muscle tissues and tendons, dental arches, salivary glands, as well as the hyoid bone and the muscles that connect the latter to the scapula and the sternum, the muscles of the neck.

May 31, 2023 · Understanding the temporomandibular joint anatomy helps explain its crucial role in the daily functionality and harmony of your jaw, neck, and head. While commonly associated with jaw movement and chewing, the temporomandibular joint’s (TMJ) intricate anatomy and connection to the neck can significantly impact headaches and craniofacial pain.
