BENSHEIM, Germany – The new inLab MC XL milling machine builds on the proven features of the existing CEREC system. However, it has been tailored to the tougher requirements of large-sized dental labs. For example, it is equipped with wear-resistant non-geared motors, while the drive shafts are fitted with rubber seals to protect them against ceramic particles.

The inLab MC XL has four motors instead of two. Two motors operate at any one time. The machine can switch to one of the other two motors as required. This has two advantages. Firstly, the machine can continue milling in the event that one of the diamond burs breaks (important for round the clock operations). Secondly, the other set of motors can be equipped with different diamond burs to cater for complex milling jobs, thus eliminating the need for a tool change. The inLab MC XL demonstrates its outstanding versatility in such complex applications – for example, when milling undercuts in a bucco-lingual or mesio-distal direction. In terms of functionality the new milling unit is comparable with a five-axis machine – thanks to the infinitely rotatable block holder in combination with the new undercutting diamond bur.

The fast twin-bur milling system has been further refined in the new inLab MC XL system. Compared with the existing model milling times have been reduced by up to 60 percent. This saves valuable time. It is now possible to mill a four-unit zirconium oxide bridge in only 30 minutes.

The large-capacity milling chamber of the inLab MC XL can handle blocks up to a maximum size of 85 x 40 x 22 mm – an increase of approximately 100 percent compared with the previous inLab milling machine. This means that dental labs are in a position to manufacture zirconium oxide bridges with a maximum of eight units.

The inLab MC XL also sets new standards in terms of precision (in the region of 25 µm). Compared with the existing inLab machine the milling steps are two to four times smaller. The high-quality surface finish reduces the time needed to adapt the restoration to the tooth and mill the occlusal surface. The CEREC MC XL delivers such outstanding precision that all-ceramic crowns can now be conventionally cemented (so far adhesive bonding has been the only option). To this end Ivoclar Vivadent has developed the new disilicate glass ceramic material “IPS e.max CAD”.

The inLab MC XL marks a further step forward in terms of user-friendliness. The colored illumination of the milling chamber indicates the current operational status of the machine. All the operating steps are shown in plain text on the display. The inLab MC XL is network-capable and only half as loud as its predecessor. Consumables and accessories can be stored conveniently in two drawers underneath the milling unit. The third drawer accommodates the 3 liter water tank.

Last but not least, all these new functions and improvements have been packaged in an attractively designed tabletop unit.
