Why CaviTAU®

Measuring bone density with CaviTAU® ultrasound technology answers three medically necessary questions without radiation exposure:

a) The question of the stability and degree of healing of the bone bed when implantation is planned

b) The question of “silent inflammation” in bone marrow/jawbone marrow defects/AIOK/”NICO”/FDOK with local RANTES/CCL5 overexpression and systemic immunological diseases

c) The – so far little studied – question of the non-exposed form of bisphosphonate-induced osteonecrosis (BONJ) without clinical training of bone sequesters
