Whenever possible, adjustments of VITA SUPRINITY PC restorations should always be performed in the partially crystallized condition. Use only suitable milling tools, low speed and little pressure to avoid
overheating in some areas.
If possible, carry out grinding adjustments of IPS e.max CAD restorations while they are still in their precrystallized (blue) state. For finishing and adjusting IPS e.max CAD, only use suitable grinding instruments. If unsuitable grinding instruments are used, chipping of the edges and local overheating may occur (observe the Ivoclar Vivadent Flow Chart «Recommended grinding tools for IPS e.max glass
ceramics»).
Check the fit on the die using visual control; adjust the fit if required.
Check the fit by seating the crown on the die.
Use steam jet and/or ultrasonic bath to remove grinding particles and any contamination from occlusion paper. Avoid localized heat during cleaning with steam. Do not sandblast with Al2O3 or abrasive beads.
.
Always clean the restoration with ultrasound in a water bath or blast with the steam jet before crystallization. Do not blast with Al2O3 or glass polishing beads.
