Dr.med.dent.Dr.(PhD) Johann Lechner has been researching “silent inflammation” in chronic bone marrow defects of the jaw for over 40 years in his practice clinic for Integrative Oral Medicine. The links between these fatty degenerative cytokine dysregulations (FDOK) have clinically proven causal links to immune diseases and cannot be detected by x-ray. His complementary invention of the novel ultrasound sonography of the jawbone, TAU, is available for practical use.
