The multi-talented prophylaxis unit offers several treatment options. The powerful, well controlled ultrasound allows gentle scaling. Over 50 different inserts allow for a wide range of applications. The reliable air-polishing technique provides for both supragingival tooth cleaning and subgingival removal of biofilms. A simple press of a button is all that’s needed to switch easily from supragingival to subgingival treatment.

the right powder for the intended use

Traditionally sodium bicarbonate powders are used for air-polishing procedures. Used in a proper and not excessively intense manner, the risk of harm to the enamel is minimal. For additional applications more gentle powders have been developed during the last years. Especially glycine, a natural amino acid, opened new indications for air-polishers, the most important being subgingival removal of biofilm.

perio function at combi

perio function

The combi is equipped with the new perio function. Simply pressing a button adapts the air pressure to provide for safe subgingival treatment with glycine powder.

piezo ultrasound

The ultrasound of combi unit operates according to the piezoelectric principle. The inserts apply planar backwards and forwards vibrations, shifting the tartar gently sideways. The patient does not feel any unpleasant hammering movements on the surface of the tooth, and the dentist can work more easily and in greater comfort.

Scaling, perio, restorative dentistry – the combi can be used for an extraordinary variety of applications.
