With the foundation of the Haranni Clinic in 2002 in the heart of Herne, Prof. Dr. Rolf Hinz's vision of a holistic dental health center became reality. Tooth and jaw diseases are not only an oral problem. "It is our responsibility to reduce the disease factor" as Dr. Kay Pehrsson and Dr. Ingo-W.Paeske, partners of dentistry at the Haranni Clinic, point out. The same applies for cause studies. This is why at the Harrani Clinic the dentistry department closely works under one roof together with orthopedics, immunologists, environmental and laboratory doctors, pain therapists, internists, neurologists, doctors for traditional Chinese medicine, otolaryngologists and also psychologists and physiotherapists. For the investigation of causes and their treatment, the Haranni Clinic also features a sleep laboratory.
