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 ...
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. [1] A crown is typically bonded to the tooth by dental cement. They can be made from various materials, which are usually fabricated using indirect methods. Crowns are ...
Dental composites are also used as indirect restoration to make crowns and inlays in the laboratory. These materials are similar to those used in direct fillings and are tooth-colored. Their strength and durability is not as high as porcelain or metal restorations and they are more prone to wear and discolouration.
It was Bindl and Mörmann [2] who named this restorative procedure "endocrown" in 1999, defining it as a total porcelain crown fixed to a depulped posterior tooth, which is anchored to the internal portion of the pulp chamber and to the cavity margins, thus obtaining macromechanical retention (provided by the pulpal walls) for restoring endodontically treated teeth.
Dental porcelain (also known as dental ceramic) is a dental material used by dental technicians to create biocompatible lifelike dental restorations, such as crowns, bridges, and veneers. Evidence suggests they are an effective material as they are biocompatible , aesthetic , insoluble and have a hardness of 7 on the Mohs scale .
CAD-CAM (aka Computer Aided Design-Computer Aided Manufacture) is a fabrication method which aids the production of dental restorations e.g. crowns, bridges, inlays and onlays. It is possible for these indirect restorations to be provided in one visit. [25] This works by first taking an intra-oral scan to produce a 3D virtual impression.
