The _______ is an exact replica of the prepared tooth.

Model
Impression
Die
Cast

The correct answer is: Die

The Die is part of the process known as indirect restorations and is used to create an exact replica of the prepared tooth. The Model (A) is a three-dimensional representation of the mouth and is not an exact replica of the prepared tooth. The Impression (B) is a negative imprint of the teeth and oral tissues and is used to create the Model, but is not an exact replica of the prepared tooth. The Cast (D) is a positive replica of the prepared tooth, but is created from the Die, not the prepared tooth itself. Therefore, the Die is the most accurate answer as it is the exact replica of the prepared tooth.
