CaviTAU vs Cavitat

The new CaviTAU® is a medical Ultrasound scanning device used in dentistry. The CaviTAU® can determine jawbone density and jawbone quality, it recognises and localises bone marrow defects, so-called cavitations.

The CaviTAU® is an important, non-invasive tool for any holistic dentist

What is the CaviTau®?

The CaviTAU® shows jawbone areas with reduced mineral density and detects inflammation around implants which are not generally shown on x-rays.
The CaviTAU® shows inflammation around root treated teeth and healing problems in previous tooth extraction areas.

The main areas where healing problems in the jawbone appear are the wisdom tooth areas and the area behind the wisdom teeth. Here the CaviTAU® shows if the extraction has healed properly and if the bone is of good quality.
The CaviTAU® is the ideal device to determine jawbone health if the dentist wants to place an implant straight after extraction.

Some other names for cavitations are also Fatty Degenerative Osteonecrosis of Jawbone (FDOJ), jawbone osteonecrosis and Neuralgia Inducing Cavitational Osteonecrosis (NICO)

What are the benefits of the CaviTAU®?

Examination with the CaviTAU® is non-invasive. All radiological examinations such as Panoramic x-ray, Digital-Volume-Tomography (DVT) or Cone-Beam-Computer-Tomogram (CBCT) are linked to health risks due to their radiation exposure. CaviTAU® ultrasound however is completely harmless because it avoids ionising X-rays.

In accordance with the ALARA principle (As Low As Reasonably Achievable) CaviTAU® should be the device of choice to check for jaw bone inflammation / infection because it has zero radiation.

CaviTAU® is a safe and effective imaging device for jawbone examination, it optimises treatment planning by providing fast, accurate, reliable and reproduceable results.

CaviTAU® is the most precise method to determine problems of jawbone density.

Interview with Dra Regeane De Pol Kaniak

WHEN and WHY should you have a CaviTAU® scan?

Research shows that jawbone inflammation can have consequences to your overall health. Therefore, if you suffer from any kind of chronic disease the CaviTAU® can show if you have infection or inflammation in your jawbone

With the CaviTAU® you can have your root canals checked if they are causing jawbone inflammation. If you had an extraction or any kind of jawbone surgery the CaviTAU® can provide vital information about if your jawbone has healed properly.

Before having an implant placed the CaviTAU® can ensure your jawbone is of good quality and your implant will be a success.

What are the differences between the new CaviTAU® and the old Cavitat®?

  • The CaviTAU® is more precise, easier to use and less prone to damage.
  • The CaviTAU® is sturdier and the results are easy to reproduce.
  • The CaviTAU® has stronger signals.

One of the main benefits is that the CaviTAU® can easily be calibrated, whereas the Cavitat cannot be calibrated.

Another advantage for the patient is that the CaviTAU® requires far less gel.

Frequently Asked Questions


The scan was developed by my dear colleague Dr Dr (PhD-UCN) Johann Lechner in Munich, Germany.

Dr Lechner is arguably the most influential holistic dentist in Europe if not worldwide. His research and developments (SkaSys®, Mindlink® and now CaviTAU®) have proven that biological / holistic / integrative dentistry is based on science.

His latest books are eye-openers for every dentist interested in the causality of jawbone necrosis and their influence on overall health.

It is an Ultrasound machine to measure bone density and show reduced mineralisation of the jaw bone. For identification of jawbone cavitations.

NICO: If the cavitation is inducing neuralgia-like nerve pain Neuralgia Inducing Cavitational Osteonecrosis

According to Dr Lechner:

  1. DICO: if the cavitation is inducing depression: Depression Inducing Cavitational Osteonecrosis
  2. RICO: if the cavitation is inducing Rheumatoid Arthritis: Rheumatoid Arthritis Inducing Cavitational Osteonecrosis
  3. CICO: if the cavitation is inducing cancer Cancer Inducing Cavitational Osteonecrosis

Helps to distinguish jaw pathologies and their spreading.

It can give more information than an x-ray.

It shows reduced bone density which can be interpreted as unhealthy bone.

  • IF you have root canal teeth and want to know if they are causing infection
  • IF you had teeth extracted, especially wisdom teeth, to check if the bone has healed properly
  • IF you suffer from any unexplained illness
  • IF you suffer from chronic disease to check if their jawbone is infection-free
  • IF you have implants and want the bone health checked around them
  • IF you consider having an implant placed to check the bone is good enough
  • The CaviTAU® gives more accurate information of the bone health / density.
  • Finds problems that x-ray miss
  • It is radiation-free
  • Completely harmless
  • Easy Reproducibility, difficult with Cavitat®
  • Signal strength is stronger
  • Easy calibration, not possible with Cavitat®, therefore more precision
  • Uses far less gel, therefore easier to keep air bubble free
