Acrylic resin was the first veneering material used to help restore the aesthetics of crown and bridges. The aim was to maintain a similar colour to natural teeth by attaching it on the labial surface of metal crown / bridges; however, resin-veneered dental prosthetics lacked stability and abrasion resistance.

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.
A crown (the dental prosthesis) is then connected to the abutment with dental cement, a small screw, or fused with the abutment as one piece during fabrication. [16]: 211–232 Dental implants, in the same way, can also be used to retain a multiple tooth dental prosthesis either in the form of a fixed bridge or removable dentures.
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 ...
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).
The dental papilla contains cells that develop into odontoblasts, which are dentin-forming cells. [3] Additionally, the junction between the dental papilla and inner enamel epithelium determines the crown shape of a tooth. [2] The dental follicle gives rise to three important entities: cementoblasts, osteoblasts, and fibroblasts. Cementoblasts ...

Vessels and nerves: :25. dental :26. periodontal :27. alveolar through channel. In dentistry, crown refers to the anatomical area of teeth, usually covered by enamel. The crown is usually visible in the mouth after developing below the gingiva and then erupting into place. If part of the tooth gets chipped or broken, a dentist can apply an ...
