Note:
- The investment rings are divested by sandblasting using Al2O3 (50 μm). Rough divestment can be carried out at a pressure of
4 bars. - Fine divestment and preparation of the crown margins is carried out using abrasive glass beads at a pressure of 2 bars.
- Completely remove reaction layer both inside and outside, as residues of the reaction layer can lead to bonding problems between the press ceramic and the veneering ceramic.
