Study Notes
Working Cast and Dies
- A working cast (or master) cast is a replica of the prepared teeth, ridges, and other parts of the dental arch.
- A die is a positive reproduction of the prepared tooth and consists of a suitable hard substance (like stone, resin, or metal) with high accuracy.
Requirements of Casts
- The cast must reproduce both the prepared and unprepared tooth surfaces.
- The unprepared teeth immediately adjacent to the preparation must be free of voids.
