Air abrasion with water spray – virtually painless, gentle and wonderfully quiet.

Whether you’re using KaVo RONDOflex to pretreat dentine, metal or ceramic surfaces or before applying adhesive systems and composite-based cements, you’ll love the multitude of clever details designed for convenient everyday use, not to mention the gentle and virtually painless surface treatment.

KaVo RONDOflex in video:

Due to the improved adhesive technology, the air abrasion unit has a completely new user focus. The minimally invasive removal of the tooth substance and direct and indirect restoration materials increase efficiency and quality for the practitioner. 

The surfaces are removed, cleaned and enlarged, thus offering a good basis for the adhesive technique. Thanks to these properties, the RONDOflex plus 360 can be used in any dental practice.

Strong. Clean. Efficient.
  • Highly efficient, minimally invasive and clean abrasion process, easy and accurate.
  • Gentle treatment with no drilling, no syringe, no noise, no vibration and no unpleasant feeling in the mouth: Comfortable for your patients, especially for sensitive patients, children and adolescents.
  • Unparalleled flexibility and smooth handling at different workplaces thanks to the MULTIflex coupling: Just a "Click" does the trick! No additional devices. No additional connections. No fiddly assembly.
  • With an additional water supply
    • Reduced overspray of powder.
    • Significantly smaller dirt radius 
    • Easier to remove corundum particles 
    • More comfortable treatment
  • incl. 2 cannulas
    • For planar spot removal

Advantages of the RONDOflex plus

The RONDOflex plus 360 is intended for minimally invasive, planar, and in-depth removal of tooth substance and materials on the restorations, such as:

  • Preparation of caries for smaller composite restorations of Classes I to VI, in depressions, fissures and incipient lesions
  • Removal of composite restorations, discolouration or amalgam tattoos
  • Repair: removal of composites and other resin-based filling materials
  • Cleaning and enlarging/roughening of the surfaces of metals, composites, acrylics, ceramics and amalgams for better adhesion
  • Pre-treatment of the surface when bonding orthodontic brackets, veneers and aligners

Accessories & Testimonials


Four different cannulas for different applications:

  • 110° small (0.46 mm) – powerful cannula for spot treatment
  • 110° large (0.60 mm) - powerful cannula for planar treatment
  • 90° small (0.46mm) – better molar access for spot treatment
  • 90° large (0.60 mm) – better molar access for extensive treatment

The removal rate depends on the powder.

Choice between two corundum powders with different granulation – clearly colour-coded.

Case study and field reports RONDOflex plus 360

Clinical case study "Air abrasion system with water spray" by Dr Thierry Caires, Dentist from France: The versatile use of RONDOflex plus 360 in applications using veneers, pre-treatment for e.max overlays and before inserting different zirconium crowns. The cleaning power ensures a better structure of the surface of materials and on the tooth and thus ensures perfect adhesion.
