The quality also depends on the dentist the prepares the tooth for the crown. The quality of the crown depends on more than just whether it is made in the dental office or in a dental lab. Great question! It turns out that CEREC crowns and lab crowns can be different for a number of reasons. (Please remember that there are many variables not accounted for in this discussion)Īttached is an abstract about the margin gap size of various crowns. In my opinion the quality goes from better to worse in the following order:ġ) Digital impression, lab processed 2)In-office CAD/CAM (Cerec) 3)Traditional impression, traditional crown. Plus, lab processed crowns look so much better than in-office Cerec crowns. But it has also been shown that crowns made at the lab from digital impressions have even smaller margins. It has been shown that crowns made from digital impressions (which is what Cerec employs) have smaller gaps than traditional lab made metal ones. Eventually larger margins get infected or ‘leak’. Although this is small, it is important to note that bacteria are smaller.
The gap is small and measured in microns (0.00039 inches). The reason is that one of the major causes of crown failure over time is the gap between the crown and the tooth, what dentists call the margin. If you value esthetics and longevity of the crown, then Cerec might not be your best choice. If your priority is convenience then the one-day Cerec crown is probably the best choice. So there is no need for a second appointment and second injection.It depends what you want. Furthermore, the whole procedure is carried out in one visit, The digital camera is more comfortable than the traditional impressions taken Patients report the scanning of the tooth with Procedure is generally carried out with a local anesthetic and is no moreĭifferent to having a filling.
