What Is CEREC?
CEREC (Chairside Economical Restoration of Esthetic Ceramics) is a CAD/CAM system that lets dentists scan, design, mill, and seat permanent restorations in a single appointment. No impression trays, no temporaries, no second visit. The patient walks out with a final crown, inlay, onlay, or veneer the same day.
The system has three core components: the Primescan intraoral scanner captures a 3D digital impression, the CEREC Software (or cloud-based CEREC on DS Core) handles restoration design using a biogeneric algorithm called the "Biojaw process," and the Primemill milling unit carves the restoration from a block of ceramic, composite, or zirconia. For zirconia and certain glass ceramics, the SpeedFire furnace handles sintering — a full-contour zirconia crown can be sintered in as little as 10-15 minutes.
The newest scanner, the Primescan 2 (released September 2024), is the first cloud-native intraoral scanner — it runs on any internet-connected device through the DS Core platform rather than requiring a dedicated cart. This is a meaningful shift toward making CEREC more flexible and less hardware-dependent.
CEREC supports a wide range of validated materials: zirconia, lithium disilicate (e.g., IPS e.max), hybrid ceramics (VITA Enamic), composites, and feldspar ceramics. Workflows span restorative dentistry, implantology (abutment crowns, screw-retained crowns, surgical guides), and even orthodontics through the SureSmile aligner integration.
Key Features
Scanning (Primescan / Primescan 2)
High-speed intraoral scanning with full-arch capture. The Primescan 2 adds cloud-native operation — no dedicated cart required, works on laptops and tablets. Accurate enough for single units through full-arch restorations.
Design (CEREC Software / CEREC on DS Core)
The Biojaw process generates a patient-specific restoration proposal based on the scanned anatomy. In many cases, the AI-driven design can be accepted without manual adjustment, though full manual control is available. Cloud-based design through DS Core enables remote collaboration and case sharing.
Milling (Primemill / Primemill Lite)
The Primemill can rough-mill a composite or hybrid ceramic crown in approximately 4 minutes. Zirconia crowns mill in about 5 minutes before sintering. The Primemill Lite offers a more affordable entry point with the same core milling capabilities.
Sintering (SpeedFire)
Required for zirconia and certain glass ceramic materials. Full-contour zirconia crown sintering in 10-15 minutes — fast enough to keep the single-visit workflow intact.
Materials Flexibility
One of CEREC's genuine advantages is the breadth of validated materials. You're not locked into one material type — you can choose the right material for each clinical situation.
DS Core Platform
Dentsply Sirona's cloud platform connects CEREC to practice management, imaging, and collaboration tools. Case sharing with labs, remote design reviews, and cloud storage for scans and designs.
