Working Casts And Dies In Fixed Partial Dentures(FPD)

Abstract

Fixed Partial Dentures (FPDs) are among the most common prosthodontic treatments used to

replace missing teeth. A critical component in their fabrication is the use of working casts and dies,

which ensure accuracy, precision, and durability of the final prosthesis. This article summarizes thekey concepts of working casts and dies, their materials, requirements, and systems.The quality of these replicas influences the adaptation, occlusion, and marginal fit of the prosthesis. This article discusses the concept, types, materials, and procedures involved in the fabrication of working casts and dies, emphasizing their clinical significance and the advancements that have improved precision in modern prosthodontics.
