A set of one or more false teeth supported by a metal framework, used to replace one or more missing teeth. Bridges may be fixed or removable. A fixed bridge (a partial denture) is a prosthetic replacement of one or more missing teeth; it is cemented (or otherwise attached) to the neighboring teeth or may be implanted in the space. A removable bridge (partial denture) is a prosthetic replacement of one or more missing teeth on a framework that can be removed by the wearer.

- Wheatstone b. an apparatus for measuring electrical resistance; four resistors are connected to form the four sides or “arms” of a square; a voltage is applied to one diagonal pair of connections, while the voltage between the other diagonal pair is measured, e.g., by a galvanometer; the b. is “balanced” when the measured voltage is zero; then, the ratios of the two pairs of adjoining resistances must be identical.

(in dentistry) a fixed replacement for missing teeth. The artificial tooth is attached to one or more natural teeth, usually by a crown. Bridges may also be fitted on dental implant. The supporting teeth (or implants) are referred to as abutments, and the artificial teeth that fit over them are referred to as retainers. The replacements of missing teeth are known as pontics. Adhesive bridges are attached to one or more adjacent teeth by a metal plate that adheres to the enamel on the tooth surface prepared by the acid-etch technique; these bridges require minimal tooth preparation compared with conventional types of bridges.
