Abstract
Improved apparatus for positioning and suspending paraphernalia in a dental negative mould comprising a pair of pins insertable into the mould along the buccolingual midline of the tooth to be made detachable from the remainder of the dental cast or model. The paraphernalia articulates with the pins and is precisely positionable in the mould due to unique structure of the jig assembly and paraphernalia, or tooth die forming member, which permits movement of the latter along or rotation about three different axes.
