A method for producing in a single casting operation a dental model including a unitary tooth die which incorporates an integral mounting pin. The pin and die form a part of, and are removable from the dental model. Prior to casting the die, a bayonet shaped mounting pin is held in position by a permanent divider which, in turn, is supported in a negative impression of a denture. The die and base are then cast simultaneously, eliminating the need for the more commonly used double casting procedure.
