Darren Greenhalgh There are so many aspects to a successful CEREC appointment. Scheduling, anesthetic, preparation, powdering, imaging, designing, milling, staining and glazing, staff participation – it can be stressful.
In and effort to always be more efficient in my office, we have really worked on most of these aspects, but I still find after all of these years the only time my blood pressure rises during a CEREC appointment: bonding the restoration. Everything we have do up to this point depends on how successful we are when seating the crown – everything is additive in the CEREC process, so one thing that I always try and check to make sure that I am getting the best bond possible – the intaglio surface of my margin.
If you get any glaze or stain on your intaglio surface you will not get as good of a bond as you could if there were no glaze or stain present. I know that many people stain and glaze differently – I for one use a vice made from Vita to hold my restorations in place while staining and glazing.
If you are not very careful, you can introduce stain or glaze onto the intaglio marginal surface.
I use a fine diamond at slow speed to roughen up the glaze or stain that might be present before my assistant applies the silane and bond to the restoration.
