The force applied by the masticatory muscles in dental occlusion.

In some animals, the jaws together with their horny covering. The beak usually refers to the bill of birds in which the whole varies greatly in form according of the food and habits of the bird. While the beak refers most commonly to birds, the anatomical counterpart is found also in the turtle, squid, and octopus. (From Webster, 3d ed & Storer, et al., General Zoology, 6th ed, p491, 755)

"Bites and stings refer to tissue damage or toxic reactions caused by the teeth, mouthparts, or venomous secretions of animals such as insects, spiders, snakes, and mammals during predatory or defensive attacks."

The act and process of chewing and grinding food in the mouth.

A registration of any positional relationship of the mandible in reference to the maxillae. These records may be any of the many vertical, horizontal, or orientation relations. (Jablonski, Illustrated Dictionary of Dentistry)

Muscles arising in the zygomatic arch that close the jaw. Their nerve supply is masseteric from the mandibular division of the trigeminal nerve. (From Stedman, 25th ed)

Bites by snakes. Bite by a venomous snake is characterized by stinging pain at the wound puncture. The venom injected at the site of the bite is capable of producing a deleterious effect on the blood or on the nervous system. (Webster's 3d ed; from Dorland, 27th ed, at snake, venomous)

Bony structure of the mouth that holds the teeth. It consists of the MANDIBLE and the MAXILLA.

Bites inflicted by humans.

Bites and stings inflicted by insects.

A masticatory muscle whose action is closing the jaws; its posterior portion retracts the mandible.

A malocclusion in which maxillary incisor and canine teeth project over the mandiblar teeth excessively. The overlap is measured perpendicular to the occlusal plane and is also called vertical overlap. When the overlap is measured parallel to the occlusal plane it is referred to as overjet.

A masticatory muscle whose action is closing the jaws.

The effects, both local and systemic, caused by the bites of SPIDERS.

The mouth, teeth, jaws, pharynx, and related structures as they relate to mastication, deglutition, and speech.

The relationship of all the components of the masticatory system in normal function. It has special reference to the position and contact of the maxillary and mandibular teeth for the highest efficiency during the excursive movements of the jaw that are essential for mastication. (From Jablonski, Dictionary of Dentistry, 1992, p556, p472)

A condition in which certain opposing teeth fail to establish occlusal contact when the jaws are closed.

The SKELETON of the HEAD including the FACIAL BONES and the bones enclosing the BRAIN.

The complement of teeth in the jaws after the eruption of some of the permanent teeth but before all the deciduous teeth are absent. (Boucher's Clinical Dental Terminology, 4th ed)

The properties, processes, and behavior of biological systems under the action of mechanical forces.

The most posterior teeth on either side of the jaw, totaling eight in the deciduous dentition (2 on each side, upper and lower), and usually 12 in the permanent dentition (three on each side, upper and lower). They are grinding teeth, having large crowns and broad chewing surfaces. (Jablonski, Dictionary of Dentistry, 1992, p821)

Such malposition and contact of the maxillary and mandibular teeth as to interfere with the highest efficiency during the excursive movements of the jaw that are essential for mastication. (Jablonski, Illustrated Dictionary of Dentistry, 1982)
