For a resilient mounting of a spider die onto a dental prosthetic suprastructure on a male spider mold, at least one retention element is molded onto a sleeve, and the retention element has a substantially occlusal alignment. The at least one retention element extends across the entire length of the sleeve and has a head having a connecting neck in its cross-section. In this manner, retention undercuts 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 thus created, which has an improved retention with an increased retention force at a smaller installation height. |
