Chrome-cobalt disc with bridges and crowns manufactured using WorkNC Dental CAD/CAM. CAD/CAM dentistry is a field of dentistry and prosthodontics using CAD/CAM (computer-aided-design and computer-aided-manufacturing) to improve the design and creation of dental restorations, [1] [2] especially dental prostheses, including crowns, crown lays, veneers, inlays and onlays, fixed dental prostheses ...
Dental implant, 3D illustration. A dental implant (also known as an endosseous implant or fixture) is a prosthesis that interfaces with the bone of the jaw or skull to support a dental prosthesis such as a crown, bridge, denture, or facial prosthesis or to act as an orthodontic anchor.
In dentistry, a crown or a dental cap is a type of dental restoration that completely caps or encircles a tooth or dental implant. A crown may be needed when a large dental cavity threatens the health of a tooth. Some dentists will also finish root canal treatment by covering the exposed tooth with a crown.
Crown to root ratio is the distance from the occlusal/incisal surface of the tooth to the alveolar crest in relation to the length of root within the bone. The minimum ratio of crown to root is considered to be 1:1, although the most favourable is a crown:root of 2:3. As the proportion of tooth supported by bone decreases, the lever effect ...
Extracoronal preparations provide a core or base upon which restorative material will be placed to bring the tooth back into a functional and aesthetic structure. Examples include crowns and onlays, as well as veneers. In preparing a tooth for a restoration, a number of considerations will determine the type and extent of the preparation.
In dentistry, an abutment is a connecting element. [1] This is used in the context of a fixed bridge (the "abutment teeth" referring to the teeth supporting the bridge), partial removable dentures (the "abutment teeth" referring to the teeth supporting the partial) and in implants (used to attach a crown, bridge, or removable denture to the dental implant fixture).
A dental prosthesis is an intraoral (inside the mouth) prosthesis used to restore (reconstruct) intraoral defects such as missing teeth, missing parts of teeth, and missing soft or hard structures of the jaw and palate. [1]
A full veneer crown is described as "a restoration that covers all the coronal tooth surfaces (mesial, distal, facial, lingual and occlusal)". [citation needed] Laminate veneer, on the other hand, is a thin layer that covers only the surface of the tooth and is generally used for aesthetic purposes. These typically have better performance and ...
