Dental 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. (From Jablonski, Dictionary of Dentistry, 1992, p2)

Dental Abutment

The process of refitting a denture by replacing the denture base material without changing the occlusal relations of the teeth. Rebasing may include adding to the denture base to compensate for resorptive changes to subjacent structures.

Denture Relinings
The process of refitting a denture by replacing the denture base material without changing the occlusal relations of the teeth. Rebasing may include adding to the denture base to compensate for resorptive changes to subjacent structures.

Denture Repair
The process of reuniting or replacing broken or worn parts of a denture.

Denture Retention
The retention of a denture in place by design, device, or adhesion.

Denture Stability
The retention of a denture in place by design, device, or adhesion.

Denture Stomatitides
Inflammation of the mouth due to denture irritation.

Denture Stomatitis
Inflammation of the mouth due to denture irritation.

Denture Wear
Occlusal wear of the surfaces of restorations and surface wear of dentures.

Denture, Complete
A denture replacing all natural teeth and associated structures in both the maxilla and mandible.

Denture, Complete, Immediate
A complete denture constructed for replacement of natural teeth immediately after their removal. It does not fit the mouth perfectly and is intended only for functional and cosmetic purposes during the healing process after total extraction. It is to be replaced by the fitted permanent denture.

Denture, Complete, Lower
A complete denture replacing all the natural mandibular teeth and associated structures. It is completely supported by the oral tissue and underlying mandibular bone.

Denture, Complete, Upper
A complete denture replacing all the natural maxillary teeth and associated maxillary structures. It is completely supported by the oral tissue and underlying maxillary bone.

Denture, Fixed Partial
A partial denture attached to prepared natural teeth, roots, or implants by cementation.

Denture, Overlay
Removable prosthesis constructed over natural teeth or implanted studs.

Denture, Partial
A denture replacing one or more (but not all) natural teeth. It is supported and retained by underlying tissue and some or all of the remaining teeth.

Denture, Partial, Fixed
A partial denture attached to prepared natural teeth, roots, or implants by cementation.

Denture, Partial, Fixed, Resin-Bonded
A commonly used prosthesis that results in a strong, permanent restoration. It consists of an electrolytically etched cast-metal retainer that is cemented (bonded), using resins, to adjacent teeth whose enamel was previously acid-treated (acid-etched). This type of bridgework is sometimes referred to as a Maryland bridge.

Denture, Partial, Immediate
A partial denture constructed before the teeth it replaces are removed. It is then inserted immediately after the removal of the natural teeth for functional and cosmetic reasons during the healing process. It is to be replaced later by the fitted partial denture.

Denture, Partial, Removable
A partial denture designed and constructed to be removed readily from the mouth.

Denture, Partial, Temporary
A partial denture intended for short-term use in a temporary or emergency situation.

Dentures
A denture or a complete denture as it is often called, is an appliance that is inserted in the mouth, replaces natural teeth and provides support for the cheeks and lips. Most dentures are made of acrylic and can be fabricated two different ways. A conventional denture is made after all teeth have been extracted and the tissues (gums) have healed. An immediate denture is fabricated and inserted immediately after the teeth are extracted and the tissues are allowed to heal under the denture. An upper denture has acrylic, usually flesh colored, that covers the palate (roof of the mouth). A lower denture is shaped like a horseshoe to leave room for the tongue. The teeth are made of plastic, porcelain or a combination thereof. Dentures can be fabricated to fit over endodonticly treated teeth (See "Root Canals") and a complete denture can be attached to implants (See "Implants") to allow for a more secure fit of the appliance. Dentures over a normal course of time will wear and need to be replaced or relined in order to keep the jaw alignment normal. The alignment will slowly change as the bone and gum ridges recede or shrink due to the extraction of the teeth. Regular dentist examinations are still important for the denture wearer so that the oral tissues can be checked for disease or change. See also "Partial Dentures."
