Apply Soft Newport Wax to the end of a 10-gauge sprue. If the wax-up is unusually large, use an 8-gauge wax sprue to ensure complete pressing.

While the wax-up is still on the die, place a small amount of wax on the end of the sprue and attach it 2 mm to 3 mm from the incisal edge at a 45-degree angle to the lingual.

Crowns should be at least one quarter inch from inside of ring with margins facing upward. To ensure complete pressing, the units should not be touching.
