The Cerec CAD/CAM is a technology that enables dentists to intraorally scan a patient’s mouth, mill, and install crowns, veneers, bridgework, and inlays in a single appointment. The dentist begins by removing all decay from the tooth, followed by a proper filling. Since only minimal preparation is required, there’s no need to create a fully retentive form, which enables the doctor to retain a greater portion of the existing tooth. Full ceramic crowns are cemented using special adhesive techniques, which allow for tooth preservation and reduce both the risk of damaging the pulp and the need for a fully retentive form, unlike conventional cementing techniques. During this procedure, patients are numbed to prevent any pain.
Instead of making an impression of the teeth like the conventional way, the dentist uses a special scanning device that provides a detailed 3D image of the tooth. Instead of using impression material, a light dusting of reflective powder is used to get the digital records of the teeth, including the form and preparation margins. The images are sent to a computer, where the dentist receives an exact digital model of the teeth, including all the hills and valleys. Then he has to review the image and decide if there’s a need to make any corrections to the tooth. Should he need to make any improvements, another series of images can be taken very easily to get the appropriate image, after which the reflective powder is rinsed with water from the patient’s mouth.
The next step is designing the crown. The Cerec CAD/CAM system offers software with a database that contains a variety of different tooth forms from which the dentist can choose by trying on various forms until they find the right one. The software features multiple functions, including replicating the opposite tooth to create a crown that closely resembles the natural one. This way, the dentist gets a virtual restoration, which is sent to a milling unit. After designing the crown, the dentist has to choose the right color and shade of the material. This system uses small blocks of ceramic material.
The best material for Cerec is lithium disilicates, such as Emax and Suprinity. These materials can be easily manipulated by the dentist and offer better aesthetics than monolithic zirconia, making them a suitable alternative for one-sitting appointments.
In our clinic, we use Zirconia, Lithium disilicate, Feldspar ceramics, and lithium disilicate zirconia hybrid materials (Vita Suprinity). For many years, we have successfully used this material in our dental clinic. In our clinic, we use the Sirona InLab MC XL, IMES ICORE 250 I, and Ideal mill milling units. The milling process typically takes up to five minutes, allowing the patient to receive the restoration on the same day. On the other hand, with the conventional method, getting a crown can take up to a month and requires several visits to the dentist’s office.
When milling is finished, the dentist can take the crown, try it on, and assess whether any adjustments are needed. Different stains and a glaze can be added to enhance the appearance of the crown, and this process takes only 10 minutes to complete. Once the crown is complete, it can be cemented to the prepared tooth. With this, the tooth regains its natural form, appearance, and function. As our patient, you can fully benefit from the luxury of choosing between different types of restoration packages that come with the CAD/CAM system such as Dental Crowns, Bridges, Inlays, Onlays, and Veneers.
The milling of a Cerec crown takes around 7-15 minutes on average. The best part is that scanning, milling, glazing of the restoration, and installation can be done in one visit. Our esteemed patients receive high-quality restorations with absolutely no need for waiting. Multiple visits to the doctor’s office, impression taking, or temporary crowns are not necessary because our dental laboratory is an integral part of our clinic, which serves us immediately. Restorations made with CAD/CAM are significantly more precise and fit much better than those made by hand. Because we utilize ceramic materials with high biocompatibility, free from any side effects, you receive a natural-looking and long-lasting restoration. This way, our qualified doctors can improve your smile in just one visit…
