The relationship of occlusal wear to occlusal contact area. 1983

M D Russell, and A A Grant

It has been suggested that masticatory efficiency is directly related to the area of the occlusal surfaces that make contact. However, little work has been carried out to determine if occlusal wear increases the area of contact, and controversy exists as to whether this would be an advantage. Using a wax registration method, occlusal contact area was measured in a group of individuals with either local or generalized wear, before and after treatment. The changes in occlusal contact area were statistically significant for the group exhibiting generalized wear but not for the group exhibiting localized war.

D007574	Jaw Relation Record	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.

D008409	Mastication	The act and process of chewing and grinding food in the mouth.	Chewing
D003766	Dental Occlusion	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.

D014072	Tooth Abrasion	The pathologic wearing away of the tooth substance by brushing, bruxism, clenching, and other mechanical causes. It is differentiated from TOOTH ATTRITION in that this type of wearing away is the result of tooth-to-tooth contact, as in mastication, occurring only on the occlusal, incisal, and proximal surfaces. It differs also from TOOTH EROSION, the progressive loss of the hard substance of a tooth by chemical processes not involving bacterial action.
