Your dentist is in complete control of the final result - since the crown or veneer is designed and fabricated from start to finish by your dentist, he/she 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. Only one set of local anaesthetic injections - since the entire procedure can be carried out within the hour, you only need to have one lot of injections. There are several advantages to having treatment with CEREC over conventional, laboratory-made restorations:Įverything is carried out in a single visit - you only need to visit the dentist once - take one day away from your work or life to have the procedure - instead of the usual two or three visits. Large metal fillings replaced with CEREC fillings. Your new restoration will then be cemented into place onto your prepared tooth. 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. The ceramic blocks come in a wide variety of shades and colours, and your tooth will be selected to match your surrounding teeth. The latest CEREC MCXL machine can mill a crown in as little as 6 minutes. 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.
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. This image is then converted into a 3D computerised model of your tooth, which is used as a guide to design your new restoration. At this point, instead of using "dental putty" to take an impression of your tooth, a digital image is taken using a special camera. Your dentist will prepare your tooth in the normal way he/she would before fitting a crown or a veneer. CEREC computerised design unit (left), and milling unit (right).
