Garrison Dental Solutions

The eZr™ Polishing System from Garrison Dental Solutions provides a processing solution that not only produces a high gloss finish on zirconia, but has also been shown to increase its physical stability through polishing.  Highly polished, stable zirconia surfaces are now attainable.

eZr is a three-step diamond polishing system including grinders and polishers for adjusting and correcting chairside restorations such as inlays, onlays, veneers and crowns.  The kit includes multiple shapes (point, cup and disc) with 2 coarse grinders for adjusting, 3 medium grit polishers for smoothing and pre-polishing, and 3 fine grit polishers for high gloss polishing.  There are refills available for each. 

The coarse grinders achieve a high material removal rate, while allowing heat dissipation from the processed material.  This can be of great significance as the unique material characteristics of zirconia require specific processing tools.  The eZr grinders use cool grinding to avoid heat development and consequential micro-crack development.

The correct processing of zirconia has been a controversial issue due to the risk of microfracturing.  Finishing with the appropriate instruments is now possible and produces long term stability of the restoration.  The polishers have a long life and, in combination with a high material removal rate, allow for an economic and fast processing system to get to glossy in seconds, without polishing paste.
