Superstructure Components of Bridges. Fixed bridge: A dental prosthesis that is definitively attached to natural teeth and replaces missing teeth.. Abutment: The tooth that supports and retains a dental prosthesis.. Pontic: The artificial tooth that replaces a missing natural tooth.. Abutment. A fixed arch is most commonly used on shorter, concrete bridges. Bridge. The superstructure of the bridge structure consists of deck slab, girder, truss etc. v Components of bridge The bridge structure comprises of the following parts. Superstructure of the bridge bears the load passing over it. Usually, bridge pier is constructed by in situ method with large panel formwork.

This bears the load passing over it and Calibre / Caliber. The five major parts of Bridges - Concrete Span Bridge, During the design process, every bridge can be divided broadly into three parts. Today, a caliber refers to the movement number, origins or its manufacturer. Depending on the tooth that is being replaced, on rare occasions two abutments can be used on the one side to provide extra support. A two-hinged arch is generally used on mid-sized bridges because the pinned connection at the base is better able to handle temperature fluctuations. Here the pontic is attached only on the one side of the space. Resin-retained bridge. The name for a crown that is … These components vary based on the type of bridge (whether concrete or steel or composite).
