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”.
For processing, Shaper 25 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.
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.
