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. The impact of 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 second of this two part series discusses the influence of patient choice and the use of fixed bridges requiring little or no tooth preparation.

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