Denture Design: The plan, delineation, and location of actual structural elements of dentures. The design can relate to retainers, stress-breakers, occlusal rests, flanges, framework, lingual or palatal bars, reciprocal arms, etc.Denture Retention: The retention of a denture in place by design, device, or adhesion.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.Jaw, Edentulous, Partially: Absence of teeth from a portion of the mandible and/or maxilla.Denture, Complete: A denture replacing all natural teeth and associated structures in both the maxilla and mandible.Dental Articulators: Mechanical devices that simulate the temporomandibular joints and jaws to which maxillary and mandibular casts are attached. The entire assembly attempts to reproduce the movements of the mandible and the various tooth-to-tooth relationships that accompany those movements.Dentures: An appliance used as an artificial or prosthetic replacement for missing teeth and adjacent tissues. It does not include CROWNS; DENTAL ABUTMENTS; nor TOOTH, ARTIFICIAL.Denture Bases: The part of a denture that overlies the soft tissue and supports the supplied teeth and is supported in turn by abutment teeth or the residual alveolar ridge.

It is usually made of porcelain or plastic.Denture, Overlay: Removable prosthesis constructed over natural teeth or implanted studs.Denture Rebasing: 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, 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.Acrylic ResinsDenture Repair: The process of reuniting or replacing broken or worn parts of a denture.Dental Materials: Materials used in the production of dental bases, restorations, impressions, prostheses, etc.Jaw, Edentulous: The total absence of teeth from either the mandible or the maxilla, but not both. Total absence of teeth from both is MOUTH, EDENTULOUS. Partial absence of teeth in either is JAW, EDENTULOUS, PARTIALLY.Polymethyl Methacrylate: Polymerized methyl methacrylate monomers which are used as sheets, moulding, extrusion powders, surface coating resins, emulsion polymers, fibers, inks, and films (From International Labor Organization, 1983). This material is also used in tooth implants, bone cements, and hard corneal contact lenses.Denture Identification Marking: Any system of defining ownership of dentures or dental prostheses.Mouth, Edentulous: Total lack of teeth through disease or extraction.Dental Abutments: Natural teeth or teeth roots used as anchorage for a fixed or removable denture or other prosthesis (such as an implant) serving the same purpose.Materials Testing: The testing of materials and devices, especially those used for PROSTHESES AND IMPLANTS; SUTURES; TISSUE ADHESIVES; etc., for hardness, strength, durability, safety, efficacy, and biocompatibility.Dental Prosthesis, Implant-Supported: A prosthesis that gains its support, stability, and retention from a substructure that is implanted under the soft tissues of the basal seat of the device and is in contact with bone. (From Boucher's Clinical Dental Terminology, 4th ed)Dental Stress Analysis: The description and measurement of the various factors that produce physical stress upon dental restorations, prostheses, or appliances, materials associated with them, or the natural oral structures.Dental Casting Technique: The process of producing a form or impression made of metal or plaster using a mold.Pliability: The quality or state of being able to be bent or creased repeatedly. (From Webster, 3d ed)Dental Clasps: Metal devices for fastening together two or more parts of dental prostheses for stabilizing or retaining them by attachment to abutment teeth. For a precision attachment for a partial denture DENTURE PRECISION ATTACHMENT is available.Dental Impression Technique: Procedure of producing an imprint or negative likeness of the teeth and/or edentulous areas. Impressions are made in plastic material which becomes hardened or set while in contact with the tissue. They are later filled with plaster of Paris or artificial stone to produce a facsimile of the oral structures present. Impressions may be made of a full complement of teeth, of areas where some teeth have been removed, or in a mouth from which all teeth have been extracted. (Illustrated Dictionary of Dentistry, 1982)Chromium Alloys: Specific alloys not less than 85% chromium and nickel or cobalt, with traces of either nickel or cobalt, molybdenum, and other substances. They are used in partial dentures, orthopedic implants, etc.Dental Occlusion, Balanced: Dental occlusion in which the occlusal contact of the teeth on the working side of the jaw is accompanied by the harmonious contact of the teeth on the opposite (balancing) side. (From Jablonski, Dictionary of Dentistry, 1992, p556)Research Design: A plan for collecting and utilizing data so that desired information can be obtained with sufficient precision or so that an hypothesis can be tested properly.Denture Precision Attachment: A precision device used for attaching a fixed or removable partial denture to the crown of an abutment tooth or a restoration. One type is the intracoronal attachment and the other type is the extracoronal attachment. It consists of a female portion within the coronal portion of the crown of an abutment and a fitted male portion attached to the denture proper. (Jablonski, Dictionary of Dentistry, 1992, p85; from Boucher's Clinical Dental Terminology, 4th ed, p264)Methylmethacrylate: The methyl ester of methacrylic acid. It polymerizes easily to form POLYMETHYL METHACRYLATE. It is used as a bone cement.Prosthodontics: A dental specialty concerned with the restoration and maintenance of oral function by the replacement of missing TEETH and related structures by artificial devices or DENTAL PROSTHESES.Drug Design: The molecular designing of drugs for specific purposes (such as DNA-binding, enzyme inhibition, anti-cancer efficacy, etc.) based on knowledge of molecular properties such as activity of functional groups, molecular geometry, and electronic structure, and also on information cataloged on analogous molecules. Drug design is generally computer-assisted molecular modeling and does not include pharmacokinetics, dosage analysis, or drug administration analysis.Surface Properties: Characteristics or attributes of the outer boundaries of objects, including molecules.Mastication: The act and process of chewing and grinding food in the mouth.Methylmethacrylates: The methyl esters of methacrylic acid that polymerize easily and are used as tissue cements, dental materials, and absorbent for biological substances.Dental Restoration Failure: Inability or inadequacy of a dental restoration or prosthesis to perform as expected.Tooth Preparation, Prosthodontic: The selected form given to a natural tooth when it is reduced by instrumentation to receive a prosthesis (e.g., artificial crown or a retainer for a fixed or removable prosthesis). The selection of the form is guided by clinical circumstances and physical properties of the materials that make up the prosthesis. (Boucher's Clinical Dental Terminology, 4th ed, p239)Dental Restoration Wear: Occlusal wear of the surfaces of restorations and surface wear of dentures.Denture, Partial, Temporary: A partial denture intended for short-term use in a temporary or emergency situation.Immersion: The placing of a body or a part thereof into a liquid.Dental Polishing: Creation of a smooth and glossy surface finish on a denture or amalgam.Dental Deposits: Accumulations of microflora that lead to pathological plaque and calculus which cause PERIODONTAL DISEASES. It can be considered a type of BIOFILMS. It is subtly distinguished from the protective DENTAL PELLICLE.Dental Prosthesis: An artificial replacement for one or more natural teeth or part of a tooth, or associated structures, ranging from a portion of a tooth to a complete denture. The dental prosthesis is used for cosmetic or functional reasons, or both. DENTURES and specific types of dentures are also available.
