Using the Green State Zirconia Polishing Kit can help your lab to eliminate posterior and lingual anterior stain and glaze on full contour zirconia restorations. The process works with all types of zirconia and can be used on both pre-shaded as well as dipped white zirconia. The process was averaged to only take an extra minute per crown in the green state. It saves glaze cycles and prevents micro fracturing of sintered zirconia, leaving a long lasting enamel like polished surface on the restoration.
