CEREC Network

Operation Recommendations


Previously, radio modules were the recommended connection for sending processing jobs from the CEREC AC to MC XL-family units. As the CEREC Primemill’s firmware updates are typically much larger than those for the MC XL units, completing these updates with a radio module takes considerably longer than with a WiFi solution. CEREC Primemill also offers additional features such as remote login which require a connection to the practice (or lab) network.

For those reasons, we recommend not to use radio modules with CEREC Primemill.

Please find all details in the document CEREC Network Operation Recommendations. This document covers all CEREC network-based components.

Milling (Wet&Dry)

When processing zirconia, milling gives you sharper edges without the risk of chipping.

The new dry milling option eliminates the drying step altogether before sintering. This allows you to produce zirconia restorations in one appointment.

Also when processing polymers, you benefit from milling through more stable processing, shorter processing times and glossy surfaces.


Please note: There are no qualitative differences between wet milling and dry milling. Accuracy and detail of the result are identical in both processes. There are also no time differences between wet and dry milled restorations. Only the pre-drying time during sintering of zirconium oxide is eliminated with dry-milled restorations.

Milling individual surgical guides from PMMA

Combining the CEREC Workflow with 3D images from our 3D imaging family means greater safety for newcomers and professionals:

Integrated implantology enables you to surgically plan implants and implement the plan precisely using a surgical guide.

CEREC Guide 3 enables you to place the premium implant systems, Ankylos, Astra Tech Implant System EV and Xive, from Dentsply Sirona Implants fully guided. 

Thereby, CEREC Guide 3 can be fast and easily produced in your practice within less than an hour, and at a very low cost.

CEREC Guide 3

Using CEREC Guide 3 with Dentsply Sirona implants, you can work with the security of a precise “fully guided” procedure. This means all surgical steps, from soft-tissue punch to implant insertion, are performed with the guide in place.

The "Sleeve-on-Drill” system by Dentsply Sirona Implants replaces the drill keys otherwise used in guided surgery. The pre-mounted guiding sleeves save you an assisting hand and ensure the precise transfer of the planned implant procedure to the real surgery.

No freehand surgery can match this accuracy.  


The benefits of the CEREC Guide 3 surgical guide:

  • Fully-guided implant placement for the highest degree of clinical safety
  • Most commonly used implant sizes and lengths are covered
  • Fastest inhouse production at very low cost
CEREC Guide 3 is compatible with:
  • Ankylos
  • Astra Tech Implant System EV
  • Xive


Further information on integrated implantology with CEREC.


CEREC Guide 2

CEREC Guide 2 is a further development of the CEREC Guide product. This is a surgical guide that supports the dentist while drilling by specifying direction and drilling depth in accordance with the implant plan. CEREC Guide 2 is milled from one piece of PMMA acrylic. Both conventional impressions and model production, as well as preparing radiographic templates with reference bodies become unnecessary. The entire manufacturing sequence is fully digital. CEREC Guide 2 is used with the already familiar CEREC Guide drill keys.



CEREC Guide 2 is created in essentially three phases, which can be run separately from each other in time and space.


Phase 1: Optical impression

An optical impression of the oral situation is taken. A restoration is designed that makes implant planning possible taking into account prosthetic aspects. This information is exported as an *.SSI file (OPEN GALILEOS Implant license required).


Phase 2: Implant planning

A 3D X-ray scan is taken with a Sirona X-ray unit. No X-ray reference body is required (in contrast to CEREC Guide 1). The optical data is superimposed on the 3D X-ray data. Like CEREC Guide 1, implant planning is carried out based on the D2 value (drill lengths). To create a CEREC Guide 2, a CEREC sleeve (S, M or L) must be selected (GALILEOS Implant 1.9.2 required). This corresponds to the CEREC guide drill to be used. The planning information is created as a *.DXD file.

Phase 3: Designing and milling the surgical guide

The *.DXD planning file is imported into CEREC SW 4.4 (OPEN GALILEOS Implant license required). The shape of the guide can be customized and milled on a CEREC MC X or CEREC MC XL Premium Package (devices must be capable of milling).

Implant prosthetics with CEREC - milling and grinding of meso blocks

Customized abutments and screw-retained crowns can be easily and quickly produced with the CEREC milling and grinding units.

The wide variety of materials and CEREC's compatibility with common implant systems make it safer and more convenient for your patients.


inCoris ZI meso
  • Two sizes and colors
  • After sintering: Bonding of the meso structure with the titanium base (TiBase), veneering with individual crown made of e.g. Celtra or CEREC Blocs C PC
  • Saves time compared to central production
  • Fits on all TiBase

Order form for inCoris ZI meso blocks


Selection of our material partners' materials

For even greater individuality, you also have access to our material partners' materials when making provisional and final restorations.

For meso blocks of zirconia, milling results in smoother surfaces and edges than grinding and thus reduces reworking with better esthetic results. In addition, dry milling of zirconia is an even faster process, as the 10-minute drying time before sintering is eliminated. In all three material classes, milling results in smaller sprue sizes compared with grinding, which also means shorter reworking times. In addition, milling PMMA and composites reduces deposits of material residue on the instruments, thus resulting in less damage to them.

The "Milling" option can be selected in software versions from CEREC SW 4.5, CEREC Premium SW 4.5, and CEREC Premium CAM 4.5.
The following overview is a summary of the new treatment options of the various meso blocks in CEREC milling and grinding units.

Full contour zirconia has become a very popular material in dental offices due to its high flexural strength, biocompatibility and tissue-conserving preparation. It is suitable for individual crowns as well as small bridges and can be processed in thin wall thicknesses. Since these restorations are manufactured in monolithic form, there is no risk of chipping. Another benefit is that zirconium oxide can be cemented conventionally.
