ABSTRACT:
A device for construction of removable dental dies fabricated from type IV dental die stone poured into non-rigid impression materials. The device eliminates the need for a two pour system necessitated when individual pins are used, provides large surface area for positive seating of the individual dies, and in general eliminates the complicated alignment problems associated with other systems in common use. The invention comprises a polymer sheet having projections on both sides for embedment in dental store of the date of the die and base.
