What is CEREC?
CEREC is a revolutionary system that enables your dentist to design, fabricate and fit a new crown, veneer, onlay or inlay in a single visit, a procedure that would normally take at least two weeks if not more!

How does CEREC technology work?
Dr. Hatch will prepare your tooth in the normal way he would before fitting a crown or a veneer. At this point instead of using “dental putty” to take an impression of your tooth, a digital image is taken using a special camera. This image is then converted into 3D computerized model of your tooth which in used as a guide to design your new restoration. Once Dr. Hatch is happy with the newly designed tooth, this data is sent to an onsite milling machine which fabricates your new tooth from a high quality ceramic block. The milling process can take anywhere from as little as 6 minutes to 30 minutes depending on the exact technology and complexity of the tooth. The latest CEREC MCXL machine can mill a crown in as little as 6 minutes.
The ceramic blocks come in a wide variety of shades and colors, and is selected to match your surrounding teeth. Once the crown or veneer has been milled the dentist may characterize it and stain it to match your surrounding teeth in color before polishing it or glazing it in a furnace. Your new restoration will then be cemented into place onto your prepared tooth.

Cerec restorations can replace failing and unattractive mercury-based amalgam fillings with aesthetic and durable porcelain. In certain cases, the procedure can be conducted during a single office visit.
