This is a device that allows the dentist to make a highly aesthetic tooth replacement chairside, during a single appointment.
When the tooth has deep caries, is broken, or has undergone endodontic treatment (root canal treatment), a simple filling is not enough. Although the tooth can be reconstructed with a filling, such a large filling will crack in time, oftentimes making it impossible to restore. Such a tooth usually ends up extracted. As a precaution, the teeth are "covered" by crowns or, in the case of a minor tooth defect, by an inlay. Indirect filling is in one unit, unlike a conventional filling, which is applied in layers and gradually cured with light. Indirect filling is stronger, more aesthetic and much more precise. Cerec can be used for creating dental bridges too.
How is the treatment done with Cerec?
When the dentist decides that such treatment is needed, he or she prepares a tooth (removes caries, sharp edges, weakened parts of the tooth…). The tooth is then scanned using an intraoral scanner (see Intraoral Scanner Technology). After this step, the patient is seated in the waiting room, or can leave the office for a short time. During this time, the dentist suggests an ideal aesthetic tooth replacement in a special software. When he or she is done with planning, it is Cerec /special milling unit/ that mills the exact shape of the restoration from special blocks of different materials (composite, zirconia, ceramic). After the milling process is complete, aesthetic modification of the restoration is done (centering, glazing, individual colouring ). This process ideally takes from 15min to 1 hour. The finished restoration is then cementend in the patient’s mouth the same day.
How would treatment be done without Cerec?
There are cases where it is preferable to use a different procedure. Each case is different and specific and therefore the treatment will be considered by the dentist individually on the basis of many factors. If it is necessary to make a crown, bridge or filling other than using Cerec, classic impressions or an intraoral scan can be used. Scan data or impressions are sent to a dental lab where aesthetic restoration is done in a few days. Meanwhile, a temporary crown or a bridge is made for the patient, or the tooth is covered with a temporary filling. At the next appointment the final restoration is cemented in the patient’s mouth.
