“Treatment often used to take a long time. With CEREC I got a complete crown in just one visit – without a temporary or follow-up visits. I call that service!”
Meike Tramitz, patient from Gießen


Outstanding restorations now also with full contour zirconia

The new CEREC grinding and milling machines come equipped with a device to vacuum up the mill shavings as well as new precision tools. The new machine can be used for both wet and dry processing, one straight after the other. Dry milling saves a considerable amount of time, as the restoration does not need to be dried before sintering – thus enabling the chairside procedure. And there is no difference in quality between dry and wet milling processes. The dry dust can easily be removed using a short, integrated cleaning program.

Perform maintenance regularly. Have maintenance performed on your unit annually by trained technical personnel / a service engineer.

Observe error messages. You must observe error messages shown on the display. If the error message does not disappear even after you have performed the prompted action, contact our servicing team.

Machine care Intervals:

Once a month:

  • Change the filter
  • Clean the clamping cones of the instruments according to the cleaning set instructions
  • If the jets of water do not strike the instruments, carefully remove any foreign particles from the water nozzles with a probe.

Do not confuse the block screw with the ball pressure screw

When operating a CEREC 3 milling unit and a CEREC MC X grinding unit in the same room, be careful not to confuse the block screw of the CEREC 3 with the ball pressure screw of the CEREC MC X.

Using the tank cap opener

If you find the tank cap, tank drain or filter insert hard to open by hand, use the tank cap opener.

Wear of the ball pressure screw

The high clamping forces cause wear of the ball pressure screw.

Replace the ball pressure screw every 500 clamping operations.

Changing the water

Damage to the pump and grinding drives

An excessively high ceramic content in the cooling water will damage the pump and grinding drives. Change the water regularly.

When the water is due to be changed, a message window appears on your monitor to remind you that it is time to change the water.

Preventing odours

All grinding additives contain a biologically degradable preservative. Despite this, however, odours may still develop under unfavourable conditions.

Observe the following:

  • Change the water at least once a week.
  • With ambient temperatures above 25°C, change the water every 2 to 3 days to prevent foul odours.
  • Drain the tank if you do not intend to operate the unit for more than one week.
  • Clean the tank if the odours recurs.
  • Add DENTATEC grinding additive and fill the tank up to the brim with water. Let it stand for at least 24 hours and then rinse it out thoroughly with water once again.

Damage to surfaces

When undiluted, DENTATEC grinding additive etches plastic surfaces and can cause discolouration.

  • Do not place DENTATEC on the unit.
  • Do not spill DENTATEC.

Use only DENTATEC as a grinding additive.

Water tank MC X


Foaming is not permissible. If any cleaning agents are used, this will create foam, which is not permitted. Do not use any cleaning agents.
