For the resilient mounting of a spider die (10) onto a dental prosthetic suprastructure on a male spider mold (1), it is proposed to mold at least one retention element (14, 141, 142) onto a sleeve (11), the retention element having a substantially occlusal alignment. The at least one retention element (14, 141, 142) extends across the entire length of the sleeve (11) and has a head (143, 148) having a connecting neck (144, 147) in its cross-section. In this manner, retention undercuts (145, 146) are formed on both sides of the connecting neck. The connecting neck of the at least one retention element is molded at an offset as opposed to the crown line of the sleeve. A spider die is created in this manner, which has an improved retention with an increased retention force at a smaller installation height.
