Imagine a dental practice where you can go and have your new crown, veneer, onlay, inlay or any white filling made and fitted during a single visit and within an hour. This is what CEREC technology by Sirona Dental Systems has made possible.CEREC is a revolutionary, sophisticated CAD/CAM (computer-aided design/computer-aided manufacturing) system that enables us 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!
The dentist will prepare your tooth in the normal way it would be done 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 computerized camera. This image is then converted into a 3D computerized model of your tooth, which is used as a guide to design your new restoration.
Once your dentist is happy with the newly designed tooth, this data is sent to an onsite computerized 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 dimensions and complexity of the tooth.
The ceramic blocks come in a wide variety of shades and colors, and your tooth will be selected to match your surrounding teeth. Once the crown or veneer has been milled, your new restoration will then be cemented into place onto your prepared tooth.
There are several advantages to having treatment with CEREC over conventional, laboratory-made restorations:
Everything is carried out in a single visit – you only need to visit the dentist once – the entire procedure often takes less than an hour – instead of the usual two or three visits.
Only one set of local anesthetic injections – since the entire procedure can be carried out within the hour, you only need to be anesthetized once. There is no second or third visits that also require anesthesia.
Your dentist is in complete control of the final result – since the crown or veneer is designed and fabricated from start to finish on site, the dentist has total control over how it will look and fit, whereas a crown made in a laboratory is under the control of the technician who hasn’t even seen the patient.
No temporary restorations – if you have lab-made crowns or veneers, you would require temporary restorations during the wait period for your new teeth, often for several weeks. These temporary restorations have been known to fall off and cause problems. This step is completely omitted with CEREC restorations.
Metal-free, biocompatible materials– CEREC is a sophisticated CAD/CAM system for the production of all-ceramic, metal free inlays, onlays, partial crowns, veneers and crowns for anterior and posterior teeth.
