Fixed Dental Prosthodontics: General Principles and Stages of Bridge Fabrication

Fixed dental prosthodontics involves the fabrication of bridges to replace missing teeth and restore oral function and aesthetics. This section provides an introduction to the importance of fixed dental prostheses, discussing their indications, benefits, and the significance of adhering to established principles throughout the fabrication process.

A thorough treatment planning phase is crucial for successful fixed dental prosthodontics. This section discusses the key considerations during treatment planning, including patient assessment, diagnosis, evaluation of abutment teeth, assessment of the occlusion, and consideration of the patient’s aesthetic expectations. Understanding these aspects helps clinicians develop an individualized treatment plan that addresses the patient’s specific needs.

Proper tooth preparation is essential to achieve optimal results in fixed bridge fabrication. This section provides an overview of the principles of tooth preparation, including indications, guidelines for tooth reduction, preservation of tooth structure, and considerations for different types of abutment teeth (vital or non-vital). Detailed descriptions of different preparation designs, such as full-coverage crowns, three-quarter crowns, and veneers, are also included.

Accurate impressions are crucial for the fabrication of wellfitting dental bridges. This section discusses the materials and techniques used in impression making for fixed prostheses. It covers the selection of impression materials, tray types, and the step-by-step procedure for capturing precise impressions, including gingival retraction techniques, achieving adequate soft tissue detail, and managing impression materials around the preparation margins.

Provisional restorations play a vital role in maintaining function, aesthetics, and gingival health during the fabrication of fixed dental prostheses. This section explores the importance of provisionalization, materials used for provisional restorations, and the step-by-step procedure for fabricating and delivering temporary bridges.

Collaboration with dental laboratories is essential for the successful fabrication of fixed dental prostheses. This section provides an overview of the laboratory procedures involved, including the fabrication of working models, waxing of pontics and copings, investing and casting, metal framework try-in, and ceramic layering techniques. Understanding these processes enables effective communication and collaboration with dental technicians.

Proper cementation of fixed dental prostheses ensures longterm success. This section highlights the principles of cementation, discussing the selection of cement materials, cementation techniques, and considerations for different types of restorative materials (metal-ceramic, all-ceramic, or zirconia). It also addresses adhesive cementation techniques and the importance of achieving a strong and durable bond between the restoration and the tooth structure.

Maintaining the longevity of fixed dental prostheses requires proper maintenance and regular follow-up. This section discusses post-delivery care instructions, oral hygiene measures, and the importance of routine professional evaluations to monitor the health of the supporting structures and ensure the longevity of the restoration.

Fixed dental prosthetics, specifically bridges, are valuable treatment options for the replacement of missing teeth. This review article has provided an in-depth understanding of the general principles and stages involved in bridge fabrication. By adhering to these principles and following the step-by-step procedures outlined, dental professionals can achieve predictable outcomes and provide patients with functional, aesthetically pleasing, and long-lasting fixed dental prostheses.
