Define a die in crown and bridge fabrication and its purpose.

• A. A die is a precise replica of a prepared tooth used to fabricate the crown/bridge with accurate margins and fit
• B. A die is a wax pattern for waxing
• C. A die is an impression tray
• D. A die is a tool used to carve occlusal relief

Answer: (A)

In crown and bridge work, a die is a precise replica of the prepared tooth created from the impression so the lab can fabricate the crown or bridge with exact margins and fit. By pouring a stable material into the impression, the finish line and tooth details are reproduced on a rigid model. This lets the technician wax or build the restoration directly on the die, ensuring accurate margins, proper contacts, correct occlusal relationships, and the correct internal cement space. The die is not a wax pattern, an impression tray, or a tool for carving occlusal relief.
