Wax discs look old-school next to printed resin, but for the lost-wax path they remain the cleanest route to a pressable ceramic.
Why wax still wins for pressables
A milled wax pattern burns out with near-zero residue (<0.1% ash) and predictable shrinkage, so the pressed ceramic fits. Printed patterns can leave ash that clouds the investment.
Workflow in five steps
- Mill the pattern from a 98 mm wax disc at 60–80% speed to avoid chipping edges.
- Verify spruing angle; >10° sprue reduces voids in the copings.
- Invest within 30 min to avoid moisture uptake.
- Follow the wax's burnout curve (typically 2 °C/min to 730 °C).
- Press at the ceramic's recommended temperature window.

From disc to pressed coping
- Pick a hard wax disc for thin veneers, soft for bulk inlays.
- Mill at 8,000–12,000 rpm with a sharp 1.0 mm bur; wax loads the flutes fast.
- Remove sprues with a warm knife; never pull — you stretch the margin.
- Press at the ingot's recommended 920–940 °C; hold 10 min.
