What term describes a replica used to study the arrangement and relation of teeth in a cast?

A study model or cast is the positive replica used to examine how the teeth are arranged and relate to one another. After an impression is taken, it serves as a mold that is filled with dental stone to create this hard replica. This model lets you study alignment, spacing, occlusion, and overall dentition relationships without the patient present. An impression is the negative mold formed in the mouth and captured in material like alginate or elastomer; a die is a small, precise portion of a cast used for fabricating a crown or other restoration; and “negative reproduction” isn’t the standard term for the replica used to study the dentition.
