A position or movement of the mandible beyond its normal anatomic boundaries.  

Separation of opposing teeth during eccentric movements of the mandible. Loss of contact between opposing teeth.  

Progressive separation of occluding teeth from maximum intercuspation position during jaw movements due to tooth guidance, occlusal interferences, or occlusal adjustment.  

Pathologic displacement of a bone out of the natural anatomic boundaries of its fossae. It is frequently associated with pain, reduced range of motion of the affected bone, and ligament or cartilage pathosis. It may be chronic or recurrent. In anatomy, a displacement of a bone from its joint. A condition in which a bone…

A break of a bone associated with displacement of the fractured segment from its intended joint.  

Reduced thickness of the intraarticular disk as a result of an autoimmune degenerative process, chronic pressure during function, or the combination of both.  

The space that is typically occupied by the intraarticular disk between the mandibular condyle and the articular fossa that is represented on a temporomandibular joint radiograph as a radiolucency.  

Rotation of the temporomandibular disk downward and forward on the face of the condyle eminence.  

A bounded hole or tear in the center of the temporomandibular joint’s articular disk that is the result of deterioration associated with habitual increased compressive forces. The opening allows for communication between the superior and inferior joint spaces. The attachment associated with the capsule, ligaments, or bone is not altered.  

A dysfunction of the disk’s normal position and/or function in the temporomandibular joint in which it cannot return to normal position or function.
