Imagine a dental practice where you can go and have your new false tooth made and fitted during a single visit and within 2 hours. The Harman Clinic is the reality and this is what CEREC technology by Sirona Dental Systems (part of the Siemen’s) has made possible.
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, two day of work and two injections
Your dentist will prepare your tooth in the normal way he/she 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 a 3D computerised 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 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 20 minutes depending on the complexity of the tooth.
The ceramic blocks come in a wide variety of shades and colours, and your tooth will be selected to match your surrounding teeth. Once the crown or veneer has been milled, the dentist may characterise it and stain it to match your surrounding teeth, before either polishing it or glazing it in a furnace. 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:
