ZIRCONIA - Part 5: Surface Treatment of Pre-sintered Zirconia

Zirconia is after milling very weak and very fragile. The surface is very sentive against pollution. You should urgently use gloves and wear a face mask. At first the restoration must be removed from the block. The sprues can be cutted by a tungsten carbide bur. Then the areas of the sprues must be smoothed. The best solution is the use of a rough silicone polisher. Together with the Meisinger Company we created a small set of instruments for this. Other areas and especially the margins should be smoothed by a conical formed polisher. Finally there is a disk from the same material wich can be used for the inter proximal areas.
