| occlusal path | A gliding occlusal contact, the path of movement of an occlusal surface. (05 Mar 2000) |
|---|---|
| occlusal pattern | The form of the occlusal surface of a tooth or a row of teeth. Synonym: occlusal pattern. (05 Mar 2000) |
| occlusal plane | <dentistry> The imaginary surface on which upper and lower teeth meet. (08 Jan 1998) |
| occlusal position | The relationship of the mandible and maxillae when the jaws are closed and the teeth are in contact; it may or may not coincide with centric occlusion. (05 Mar 2000) |
| occlusal pressure | Any force exerted upon the occlusal surfaces of teeth. Synonym: biting pressure. (05 Mar 2000) |
| occlusal rest | A rigid extension of a removable partial denture onto the occlusal surface of a posterior tooth for support of the prosthesis. (05 Mar 2000) |
| occlusal rest bar | A minor connector used to attach an occlusal rest to a major part of a removable partial denture. (05 Mar 2000) |
| occlusal rim | Occluding surfaces built on temporary or permanent denture bases for the purpose of making maxillomandibular relation records and for arranging teeth. Synonym: bite rim, occlusal rim, record rim. (05 Mar 2000) |
| occlusal scheme | The form or design and arrangement of the occlusal and incisal units of a dentition or the teeth on a denture. Synonym: occlusal scheme. (05 Mar 2000) |
| occlusal splints | Rigid or flexible appliances that overlay the occlusal surfaces of the teeth. They are used to treat clenching and bruxism and their sequelae, and to provide temporary relief from muscle or temporomandibular joint pain. (12 Dec 1998) |
| occlusal surface | The surface of a tooth that occludes with or contacts an opposing surface of a tooth in the opposing jaw. Synonym: denture occlusal surface. (05 Mar 2000) |
| occlusal system | The form or design and arrangement of the occlusal and incisal units of a dentition or the teeth on a denture. Synonym: occlusal scheme. (05 Mar 2000) |
| occlusal table | The occlusal or grinding surfaces of the bicuspid and molar teeth. (05 Mar 2000) |
| occlusal vertical dimension | The vertical dimension of the face when the teeth or occlusion rims are in contact in centric occlusion; decrease in occlusal vertical dimension may result from modification of tooth form by attrition or grinding, drifting of teeth, or, in edentulous patients, by resorption of residual ridges; increase may result from modifications of tooth form, tooth position, height of occlusion rims, rebasing or relining, or occlusal splints. (05 Mar 2000) |
| occlusal wear | Attritional loss of substance on opposing occlusal units or surfaces. See: abrasion. (05 Mar 2000) |
