Barium Sulfate

Barium sulfate is used to identify the teeth from the diagnostic wax-up in a 20% BaSO4 solution. If a soft tissue (flapless surgery) template is to be made, teeth are ideally identified with a 20% BaSO 4 solution, and the base (soft tissue) uses a 10% mix. This allows for differentiation of the teeth from the soft tissue.
