Due to improved processing algorithms for the restoration base and the restoration margin, the CEREC milling and grinding units from CEREC SW 4.5.0 enable an improved fit, especially for complex preparations, thus increase patient safety.
Red and yellow areas were not removed in the old software, which could lead to problems with the fitting.
The grinding option “extra fine” allows you to reproduce very precise details–particularly finer fissure details, smoother surfaces, truer margins in areas with irregular curves as well as improved interdental details for bridges.

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.
For processing, Shaper 25 RZ must be inserted in the left spindle motor and finisher 10 in the right motor. For 4-motor machines, these burs may only be used in motor set 1.
"Dry Ready" milling unit (these devices have integrated vents in the milling chamber, which are connected to internal hoses leading to rear outlet and suction unit)
"Dry Prepared" milling unit (these devices can be retrofitted to “Dry Ready” for dry milling zirconia with a CEREC suction unit)
Unfortunately, milling units produced before these serial numbers cannot be retrofitted to “Dry Ready”.

The “fast milling/grinding” option reduces milling and grinding time by about 40%. The time saved in this production step allows you to fit your patients with high-quality, esthetic restorations even faster.

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 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.
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).
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.
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).
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.

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.

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.
The CEREC suction unit is connected to the CEREC milling and grinding unit via a communication cable and an external hose, and can thus be stowed "invisibly" in a cabinet under the CEREC grinding and milling unit, for example.
The CEREC suction unit utilizes a 5 liter dust filter bag which can be easily replaced when full (after each approx. 120 dry-milled zirconia restorations; please see page 4 of our "Cleaning and Maintenance Plan for CEREC milling and grinding units" for more information). The CEREC suction unit also contains a HEPA filter, which must be replaced after every 3-4 filter bag changes (you will also find information in our "Cleaning and Maintenance Plan for CEREC milling and grinding units" on page 5).

Milling fromt he following serial numbers are “Dry Ready”. This means they have integrated vents in the milling chamber, thus can be used for dry milling without any retrofitting:
Milling units from the following serial numbers are “Dry Prepared” and can be retrofitted to “Dry Ready” for dry milling zirconia with a CEREC Suction Unit
A retrofit kit can be ordered for “Dry Prepared” units which includes all necessary components for dry milling zirconia. The retrofit can be completed in the field by a technician and takes about 45-60 minutes.
Unfortunately, milling units produced before these serial numbers cannot be retrofitted to “Dry Ready”.
No, 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.
