Chairside Economical Restoration of Esthetic Ceramics is a type of CAD/CAM technology used in dentistry for creating dental restorations like crowns, veneers, and inlays/onlays. It allows dentists to take digital impressions of a patient's teeth, design the restoration on a computer, and then mill it out of a block of ceramic material right in the dental office.

1. Scanning Once the tooth has been cleaned and shaped appropriately for the restoration, a 3D scanner is utilized to produce an accurate digital replica of the tooth. This modern approach eliminates the need for the old-fashioned and unpleasant method of using impressions or molds to create ceramic restorations.
Using an exact replica of the tooth on a computer screen, the restoration process is designed by taking into account the position and shape of the surrounding teeth as well as your bite. The objective is to ensure that the ceramic tooth appears as natural as possible and blends seamlessly with your other teeth. 2. Designing
3. Fabrication After the design process is complete, the shade for the ceramic will be chosen to match your teeth, and the porcelain will be cut to the exact shape using a milling unit. The use of the latest "Primemill" technology ensures that this process takes no longer than 10 minutes.
4. Bonding Following the completion of the milling process, adjustments may be made to the restoration as necessary during a "try-in" procedure. After this step, the restoration undergoes preparation and polishing in readiness for the bonding process. For the bonding process, a tooth-colored cement is utilized to securely attach the porcelain to the tooth structure, creating an ideal seal and bolstering its strength.
5. Finishing During the final stage of the Cerec procedure, the restoration will be carefully examined by a dental professional to ensure that it fits precisely in your bite and complements the surrounding teeth. On average, ceramic restorations typically take about 90 minutes, while a crown may require up to two hours to complete the entire process.
