Clinical Information for Dentofacial anomalies [including malocclusion] (M26)

Malocclusion - 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)

Malocclusion, Angle Class I - Malocclusion in which the mandible and maxilla are anteroposteriorly normal as reflected by the relationship of the first permanent molar (i.e., in neutroclusion), but in which individual teeth are abnormally related to each other.

Malocclusion, Angle Class II - Malocclusion in which the mandible is posterior to the maxilla as reflected by the relationship of the first permanent molar (distoclusion).

Malocclusion, Angle Class III - Malocclusion in which the mandible is anterior to the maxilla as reflected by the first relationship of the first permanent molar (mesioclusion).

Temporomandibular Joint Disorders - A variety of conditions affecting the anatomic and functional characteristics of the temporomandibular joint. Factors contributing to the complexity of temporomandibular diseases are its relation to dentition and mastication and the symptomatic effects in other areas which account for referred pain to the joint and the difficulties in applying traditional diagnostic procedures to temporomandibular joint pathology where tissue is rarely obtained and x-rays are often inadequate or nonspecific. Common diseases are developmental abnormalities, trauma, subluxation, luxation, arthritis, and neoplasia. (From Thoma's Oral Pathology, 6th ed, pp577-600)

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

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

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

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

Alveolar Bone Loss - Resorption or wasting of the tooth-supporting bone (ALVEOLAR PROCESS) in the MAXILLA or MANDIBLE.
