CEREC one day crown technology is absolutely amazing. In one visit to your dentist, your cracked or broken tooth can be restored with a dental crown that matches the shade and shape of your natural teeth, behaves in the mouth like a natural tooth, and fits so well, it feels just like your natural tooth. There is no need for a bulky temporary crown, multiple trips to the dentist, or the grinding and shaping that can be expected when a lab-created crown is finally being placed in your mouth. This may sound way too good to be true, yet it’s not! Dr. James A. Wells of South Charlotte Dentistry in the Ballantyne area of Charlotte, North Carolina, creates CEREC crowns, every day, with astounding results. Patients find their CEREC- restored teeth look and feel much more natural than any lab created crown. Furthermore, research has shown that CEREC restorations may very well be of higher quality than a traditional lab created crown.
In an article posted to Dental Insider on May 9, 2007 the lack of quality in the dental lab industry was thoroughly investigated and discussed. Associate Q wrote:
“Recently the dental laboratory magazine LMT ran an article called ‘LMT’s 2007 Crown Experiment: Not in my mouth!’ They sent out 9 impressions to 6 domestic laboratories and 3 foreign laboratories. They were sent out as if they were coming from any “Regular Joe” Dentist, the labs were unaware they were taking part in this experiment. Once LMT received the crowns back from the labs they took them to two well known dental schools, NYU and UCONN, where they were evaluated by 11 different faculty members. You can find all the details, including a blog, at www.lmtcommunications.com, so in the interest of keeping this short I will get right to the point. The title of the article says it all; none of the crowns that were reviewed were rated as acceptable according to their scale. In fact everything was rated on a scale of 1 through 10, and none of the crowns scored above a 5 overall. Not that it matters but 10 was the good side of the scale. The evaluators went even further as those who were dentists said they would never place any of the crowns that were reviewed. (As a side note the foreign labs scored at or just below the domestic labs)”
This experiment is being repeated as many cried out that it did not reflect a good cross section of the industry. Almost 300 labs will be taking place in the next experiment. However, this 2 nd experiment is tainted, since the laboratories will know they are producing for a contest. You see what many did not get from results the experiment, what they did not fully grasp, was that these 9 crowns were from 9 different labs that operate and send out work every day. That means that this work is being seated in the mouths of patients every day. This work that was graded as unacceptable by experts, that showed obvious flaws even visible in the photographs, that was from 2 large labs, 2 medium sized labs, 2 small labs and 3 foreign labs is getting placed by dentists every day. Patients are receiving sub-par work every day. They are getting restorations that were evaluated low quality, poor fitting, not fit for placement every day, every week and every month of the year.”
With a CEREC technology, the quality is controlled from the moment you sit in Dr. Wells’ chair. Instead of a messy and inaccurate impression of your mouth, Dr. Wells will use a CAD/CAM, 3-D design & milling system to map perfect, 3d images of your mouth. These images are then utilized by the chair-side milling machine that will create your restoration with amazing accuracy (+/- 25 microns!) and with incredible speed. It takes Dr. Wells just six minutes milling time for a full–contour crown; three to four minutes for partial coverage.
The material used is much healthier for you as well. CEREC eliminates the need for amalgam, gold and other metals. Instead, solid ceramic materials are used to restore your teeth to their natural strength, beauty, and function.
These ceramic materials closely match the composition of your natural tooth structure – so when you eat hot food and then drink something cold, both the CEREC restoration and your tooth expand and contract at almost equal rates – so your tooth is not susceptible to cracking, providing you with greater confidence and peace of mind. In addition, the CEREC restoration is chemically bonded to your tooth, so Dr Wells is able to save as much healthy tooth tissue as possible while providing you with a dental restoration that actually strengthens your tooth.
