WebBarium 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. Worldwide, 69–77% of baryte is used as a weighting agent for drilling fluids in oil and gas exploration to suppress high formation pressures and prevent blowouts. As a well is drilled, the bit passes through various formations, each with different characteristics. The deeper the hole, the more baryte is needed as a percentage of the total mud mix. An additional benefit of baryte is that it is no…
