CEREC (CAD/CAM) Technology

Posted on March 3, 2015
 By sdevine Crown Restoration/CEREC
At Donato Dental, we have been using CEREC Technology to create natural-looking porcelain restorations since 2004.
Donato-Cerec1The old amalgam restoration was removed and a bonded core build-up was placed. Tooth was then prepared for a porcelain crown utilizing a microscope. Photos were taken through a camera attached to the microscope. What fun to be able to share information and a case or two with anyone interested in learning!Magnified view of the crown preparation. The margin of the preparation was just under one millimeter in depth.An optical impression of the crown preparation was obtained and a crown restoration was custom-designed on a computer-generated 3D model.The crown-design data from the computer is then sent to the milling machine which will fabricate the porcelain restoration from a solid block of porcelain in about 15-20 minutes. The porcelain blocks come in various shades and sizes.Completed CAD/CAM-created porcelain crown (palatal view).View of CEREC crown from the facial aspect.Facial view of CAD designFacial view of completed crown.

Core Build-Up & Cerec Porcelain Crown

View of new CEREC crown from other side. Thanks for watching!
Step 1: old (leaking) crown removed from subject toothThe adjacent tooth with the silver filling has a ledge (overhang) of filling material below the gum line. Overhangs accumulate plaque and makes it difficult for patients to floss without getting the floss hung-up. While I am in there working, I will address issues like this whenever I have access. Removing the old crown therefore provided access and an opportunity to smooth things up!Amalgam overhang being smoothed which will help make flossing easier for this patient.Amalgam overhang of the other adjacent tooth being smoothed here too. Ok, so back to the subject tooth…there is an existing composite build-up which appears to be separated from the natural tooth structure (looks like a fracture). This could mean that what lies underneath is…..(next slide please)…Decay!!! Lots and lots of soft cheesy decay!Decay is all cleaned up and the little remaining tooth structure is now ready for a fresh new Core Build-Up. A core build-up will help retain the crown in this case.A bonded composite material is being used for the core build-up. The material is mixed and put into a syringe with a narrow-gauge needle and applied with the aid of a surgical microscope. (Photos are obtained from a camera attached to the microscope which makes it very easy for my assistant to snap away while I’m working. As you can see, she is a bit trigger-happy!)Core Build-Up application completeGross preparation for the new crown is complete and a diode laser is being used to clean up and cauterize some inflamed gingival tissues.Refinement of crown preparation margin with a fine diamond bur (bit).Crown preparation completeJust to give a sense of the varying levels of magnification a dental operating microscope provides, this shot is taken at 2x magnification (“low mag”).3x magnificationDonato-crown148X magnification12x magnificationMargin of crown preparation is no wider than 1mm (as shown with the measuring probe).Checking margin depth on other side.Final crown preparation is sprayed with a white optical imaging medium and is ready for a digital impression utilizing CEREC technology. The crown is designed on a computer and a milling machine fabricates the porcelain crown to the exact design and specifications.Final CEREC Porcelain Crown complete and another tooth saved from extraction!

Core Build-Up & Cerec Porcelain Crown

One of the great things about using Dental Operating Microscopes (with digital cameras attached to them), is that my trigger-happy assistant can snap away while I’m working! Showing patients what I see (before, during and after treatment) is a big plus over trying to explain what I saw and did through words alone.
