RONDOflex™ plus 360

Innovative air abrasion system with a mini sandblaster and water spray.

As both a general dentist and a professor at the University of California San Francisco (UCSF), Ram Vaderhobli, DDS, MS, aims to embody the philosophy, "I practice what I teach, and teach what I practice." One product that helps him do that is KaVo's RONDOflex plus 360, an invaluable tool that's a perfect match for the conservative treatment approach he's embraced throughout his career.

Clinically, the RONDOflex is particularly useful for:

• Roughening broken fillings before composite repairs to ensure better adhesion.
• Class V lesion preparation, during which it provides gentle yet effective surface modification.
• Roughening zirconia crowns during cementation protocols to enhance bond strength.
• Removing stubborn stains caused by silver diamine fluoride applications.
• Class I pit and fissure preparation, offering a minimally invasive approach for sealant placement.
• Polishing procedures, as it effectively removes extrinsic stains without unnecessary enamel loss.

Minimally invasive treatment, maximum comfort.

A portable, easy-to-use air- and hydro-abrasion handpiece, RONDOflex requires no significant learning curve, and with minimal practice, even residents have found it to be highly beneficial during patient care. It supports the preservation of natural tooth structure by removing only the necessary amount of material, which helps maintain the tooth's strength.

The RONDOflex's 360° rotating head provides excellent accessibility, allowing effective location and removal of lesions with precision.

Because the RONDOflex utilizes a sandblasting process combined with a gentle stream of water, it eliminates the need for anesthesia and enhances patient comfort. The integrated water spray that accompanies the sandblasting process prevents excessive powder dispersion, minimizing residue and keeping the treatment area clean.

A simple technique

When working with the RONDOflex, slow, controlled strokes are recommended for precise material removal. The device's 360° swivel allows dentists to effortlessly adjust the angle to ensure that the Al₂O₃ particles are directed accurately, minimizing soft-tissue irritation while maximizing treatment efficiency.

How does it work?

By adding water spray to air abrasion technology, the RONDOflex plus 360 mini sandblaster allows for minimally invasive and in-depth removal of tooth substance and restorative materials with reduced powder mist. It cleans, roughens, and enlarges the surfaces of metals, composites, acrylics, and ceramics—providing a strong foundation for the adhesive technique.
