Fixed Dentures

Fixed dentures in dentistry is a technique used to restore teeth. Fixed prosthodontics can be used to restore single or multiple teeth, spanning areas where teeth have been lost. In general, the main advantages of fixed prosthodontics when compared to direct restorations is the superior strength when used in large restorations, and the ability to create an aesthetic looking tooth. Principles used to determine the appropriate restoration involves consideration of the materials to be used, extent of tooth destruction, orientation and location of tooth, and condition of neighboring teeth.

A crown is used to cover a tooth. Traditionally, the teeth to be crowned are prepared by a dentist, and dental impressions are given to a dental laboratory to construct the prosthesis. There are many different methods of crown fabrication, each using a different material.

Fixed partial dentures are used to span an edentulous area (space where teeth are missing), usually by connecting to fixed restorations on adjacent teeth. The teeth used to support the bridge are called abutments. The part of the bridge which replaces a missing tooth and attaches to the abutments is known as a "pontic." For multiple missing teeth, some cases may have several pontics. A bridge may also refer to a single-piece multiple unit fixed partial denture (numerous single-unit crowns either cast or fused together).
