Bridge

A dental bridge, formally known as a fixed partial denture, is a prosthetic device that replaces one or more missing teeth by spanning the edentulous space and anchoring to the adjacent teeth or implants on either side. A conventional bridge consists of retainer crowns, which are cemented onto the prepared abutment teeth, and one or more pontics, which are the artificial replacement teeth suspended between the retainers. The pontic is designed to replicate the anatomy and appearance of the missing natural tooth while maintaining contact with the underlying ridge tissue for hygienic purposes. Bridge materials include porcelain fused to metal, full ceramic or zirconia, and gold alloys, with the selection based on the location in the mouth, aesthetic requirements, and occlusal demands.

The treatment process for a conventional bridge requires at least two appointments. At the preparation visit, the abutment teeth are reduced to accommodate the retainer crowns, impressions are taken, and a provisional bridge is placed to protect the prepared teeth while the laboratory fabricates the final prosthesis. At the cementation visit, the permanent bridge is tried in, adjusted for fit and occlusion, and permanently cemented. The long-term success of a bridge depends on the health and structural integrity of the abutment teeth, the quality of the marginal adaptation, and the patient's oral hygiene practices. Alternatives to conventional bridges include implant-supported bridges, which do not require modification of adjacent teeth, and resin-bonded bridges, which use a conservative metal or ceramic framework adhesively bonded to the lingual surfaces of adjacent teeth.

Bridge cases represent significant production value and involve multiple CDT codes, as each unit of the bridge, whether a retainer crown or a pontic, is coded and billed individually. The total bridge fee is the sum of all units, and each unit may have a different code depending on the material and whether it is a retainer or a pontic. Pre-authorization is strongly recommended for bridge cases because many dental benefit plans impose waiting periods, missing tooth clauses, and frequency limitations on major prosthetic services. The billing team should verify coverage for each component of the bridge, confirm any applicable plan limitations, and communicate the estimated patient portion before treatment. Documentation should include radiographs, the reason for tooth loss, and the clinical rationale for selecting a bridge over alternative replacement options.
