Abstract: Fixed tooth replacement is a central part of prosthodontic care for patients. The approach and options for treatment have changed due to the decrease in dental disease in the population and the impact of the osseo-integrated implant. Despite the impact of the dental implant, there remain indications for the use of tooth-supported fixed prostheses. Improving oral health, the continued developments in resin-retained bridgework and the dental implant have reduced the indications for fixed prostheses retained by crowns. The last 30 years have seen a simplification in the design of fixed bridgework and this article describes the contemporary approach to this treatment modality. The first of this two part series discusses appropriate designs and the use of fixed bridges retained by crowns and the second part discusses fixed bridges where the abutment teeth require minimal or no preparation.

Clinical relevance: To assist in the appreciation of the principles of design for fixed bridgework, whether supported by crowns or resin retainers.
