3. Instructions for use
Waxing: Mininum metal thickness (after grinding) should be 0.3mm. Waxing could be as thin as 0.3mm to 0.35mm
Spruing:
A-Direct for single units. Sprueing should be 6mm in length. Based on the size and the thickness of crowns use 6-8 gauge sprues.
B-indirect for multiple units. Use straight 8 gauge sprue, about 3 or 4mm in length and connect it to the unit.
For long spanned bridges use and additional sprue connected to the last unit.
Investing: Use high heat investments. Follow the manufacturer's instuctions carefully. After investment has set, scrape the top of the investment to allow gases to escape.
Burnout: Place the ring in the furnace at room temperature, increase the temperature to 980-1050° C, with one hour holding time. Add 10/15 extra minutes for each addtional ring.
