A bridge is a fixed dental restoration (a fixed dental prosthesis) used to replace one or more missing teeth by joining an artificial tooth definitively to adjacent teeth or dental implants. Definitions

The use of a post and core does not strengthen the tooth prior to restoration with a crown; [9] rather, it may contribute to the weakening of the tooth structure, as the forces placed upon the future prosthetic crown and core are now transmitted along virtually the entire length of the brittle, endodontically treated tooth. This inherent ...
The standard also encompasses the structural design of bridge foundations [4] as well as the design and requirements of bridge bearings for both ordinary and moving bridges. [6] [7] In 2010, BS 5400 was superseded by the Structural Eurocodes for the design of new bridges. However, BS 5400 still serves as the foundation for assessment standards ...
The DMRB is used to design trunk roads such as the A20 in the UK. The Design Manual for Roads and Bridges (DMRB) is a series of 15 volumes that provide standards, advice notes and other documents relating to the design, assessment and operation of trunk roads, including motorways in the United Kingdom, and, with some amendments, the Republic of Ireland.
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.

Attempts have been made to increase the safety of bridges with pin and hanger assemblies by adding some form of redundancy to the assembly. Retrofits that add redundancy to pin and hanger assemblies include adding a "catcher's mitt"—a short steel beam attached to the bottom of the cantilevered girder that extends out beneath the suspended girder to "catch" the suspended girder should ...
