occlusal trauma (redirected from Occlusal traumatism)

occlusal trauma,

injury to a tooth and surrounding structures caused by malocclusive stresses, including trauma, temporomandibular joint dysfunction, and bruxism.

occlusal rest,

n See position, rest.

occlusal splint,

n (occlusal guard) a bite plane designed and fabricated for patients with some types of functional temporomandibular joint disorders. Provides a stable occlusal platform from which to reconstruct a functional occlusion. See also splint.

occlusal therapy,

n a treatment to establish and maintain a comfortable, stable, and functional occlusion for patients with one of several types of occlusal problems. Treatment may be limited to the teeth, the neuromuscular mechanisms of chewing, or a combination of both.

occlusal trauma,

n See trauma, occlusal.

occlusal unit,

n one of two kinds of cusps: (1) a stamp cusp coupled with a fossa, and (2) a shear cusp. The occlusal edges of the shear cusp are coupled with the edges of a stamp cusp, by which it passes closely without sliding contacts.

occlusal vertical dimension (OVD)

n the distance between a point on a maxillary tooth and a point on the opposing mandibular tooth during occlusion; several methods are used to determine this measurement, including specific facial measurements that have been proven to be equal to the OVD.

occlusal wear,

n See wear, occlusal.

trauma (trou´m, trô´m),

n a hurt; a wound; an injury; damage; impairment; external violence producing bodily injury or degeneration.

trauma, cumulative,

n medical condition developing in the peripheral and autonomic nervous systems and musculoskeletal system due to forceful, awkward, and repetitive bodily motions as well as exposure to cold temperatures, mechanical stress, and vibrations.

trauma, injury in occlusal,

n the damaging effects of occlusal trauma, which are of a dystrophic nature and affect the tooth and its periodontium. Lesions include wear facets on the tooth, root resorption, cemental tears, thrombosis of blood vessels of the periodontal membrane, necrosis and hyalinization of the periodontal mem-brane on the pressure side, and resorption of alveolar and supporting bone. Clinically, tooth mobility and migration may be evident; radiographically, evidence includes the widening of the periodontal membrane space and fraying or fuzziness of the lamina dura and formation of infrabony resorptive defects. Pocket formation is not a sequela to occlusal traumatism.

trauma, occlusal,

n abnormal occlusal relationships of the teeth, causing injury to the periodontium.
