Dr. Steffen Hohl studied medicine and dentistry at the Goethe University Frankfurt in Germany. He began his clinical training at Harvard Medical School in Boston, MA, where he trained in emergency medicine, plastic surgery and neurosurgery at Boston's Massachusetts General Hospital and the Brigham and Women's Hospital. He subsequently trained as a dentist for oral and maxillofacial surgery at the University of Cologne and the interdisciplinary trauma center in Dortmund, qualifying four years later as a consultant for oral and maxillofacial surgery and a dentist specializing in oral surgery.

In 2005, Dr. Hohl established die Zahnerei, his practice for oral and maxillofacial surgery and aesthetic dentistry in Buxtehude in northern Germany, where he is the clinical director. Die Zahnerei is also a training and professional development center for implantology and aesthetic dentistry. Steffen Hohl is the creator of the smile changer concept. He has also developed the world's first "soft sedation" process, called Schlaf-schön-Sedierung, that he has been using regularly in his practice since 2014.

With more than twenty years of experience in dental implantology, soft tissue management, and implant restoration, he has brought together his own proprietary treatment concept known as the SOAP success concept. Dr. Hohl gives regular lectures both in Germany and internationally. His special interests are the smile changer concept, SOAP success concept, immediate implantation and immediate loading. Other practice areas include aesthetic soft tissue management and plastic periodontal surgery. Another focus is the 3D planning and 3D reconstruction of the peri-implant region.
