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.
What Users Actually Say
What people love
- Single-visit workflow is transformational. Once you're proficient, doing a crown from scan to seat in under an hour changes how you practice. Patients love it. No temporaries, no second appointment.
- Material versatility. The range of validated materials means you can match the right ceramic or composite to each clinical situation — zirconia for posteriors, lithium disilicate for anteriors, composites for conservative preps.
- Proven track record. 35+ years of clinical data. Millions of restorations placed. This isn't a startup — it's the most validated chairside system in dentistry.
- Primescan accuracy. Users consistently rate the Primescan as one of the most accurate and fastest intraoral scanners available.
What people note
- Learning curve is real. Budget 3-6 months to get comfortable with the full workflow. Design software has depth, which means complexity. Dentsply Sirona offers training, but mastery takes practice.
- $129K is a big check. The upfront cost is the highest in the category. You need restorative volume to justify it.
- Software updates can be frustrating. Some users report that major software transitions have introduced bugs or required relearning workflows.
- SpeedFire adds time for zirconia. While 10-15 minutes isn't long, composite and hybrid ceramic restorations that skip sintering are noticeably faster chairside.
Who Is CEREC Best For?
Great fit:
- Restorative-heavy practices doing 5+ crowns per week
- Dentists who value same-day, single-visit workflows
- Practices that want to reduce lab dependency and control restoration quality in-house
- Offices willing to invest in the learning curve for long-term efficiency gains
May want to compare alternatives:
- Low-volume practices that won't recoup the $129K investment
- Dentists who prefer to send cases to a lab and don't need chairside milling
- Budget-conscious offices that want digital impressions only (consider the Primescan AC or competing scanners like iTero, Medit, or 3Shape TRIOS)
