Polishing of KZR-CAD HR 2 can be performed to a high level of glaze not only with diamond polisher for hybrid resin but also with general alumina polisher.

3Key Points of Setting

① Alumina Sandblasting44

② Washing with Phosphoric Acid after Trial

After trial, always wash the inside of the crown with phosphoric acid, then rinse and dry to remove saliva and blood proteins.

③ Surface treatment

Apply surface treatment agent containing silane coupling for ceramics inside of the crown, and then dry,

④ Tooth Surface Treatment

Wash tooth and perform surface treatment in accordance with the appropriate instructions for the cement to be used.

⑤ Cement Application

Apply resin cement for CAD/CAM hybrid ceramics block inside the crown in accordance with the proper operational instructions.

⑥ Pressing Down and Light-Curing

Press it down to fit and light-cure in accordance with normal operational instructions. Then, remove surplus cement and light-cure sufficiently as a final curing.
