The dentist prepares the damaged tooth by painting a thin layer of reflective powder directly on the tooth’s surface. Using a special camera, the dentist then takes a picture of the tooth. No need to take a messy impression and send it to a lab. The dentist works from this photo, which is actually a pin-sharp optical impression of the tooth.
Computer Aided Design (CAD) technology helps the dentist design the restoration from the optical impression. The design is done chair side on a color monitor. Patients can watch the dentist design the new restoration right in front of their eyes.
Then Computer Aided Manufacturing (CAM) creates the restoration while the patient waits. The tooth is milled out of a block of ceramic material that matches the patient’s tooth color. CAM uses a high-speed diamond bur and a disk simultaneously to mill a precise restoration. the milling takes about 10 minutes. Finally, the dentist bonds the newly milled restoration to the tooth using an adhesive.
