Dr. Nikolaos Daratsianos graduated from the German School of Athens / Greece. He studied at the Dental School of Frankfurt / Main in Germany and acquired the orthodontic specialization in a private orthodontic clinic and at the University Clinic of Bonn / Germany. He is the vice director of the Department of Orthodontics of the University Clinic of Bonn since 2004.

His doctoral studies were in the field of experimental orthodontics and he graduated in 2010 as one of the few orthodontists worldwide from the “Lingual Orthodontics” program, a two-year Master of Science program at the Hannover Medical School. This additional qualification allows him to treat routinely even complicated malocclusions with invisible orthodontic appliances bonded on the lingual side of the teeth. He treats almost all of his patients exclusively with lingual braces and teaches about the lingual technique. He is one of the two orthodontists in Germany and 40 worldwide who are Titular Members of the European Society of Lingual Orthodontics (highest qualification of the society).

Furthermore, Dr. Daratsianos specializes on the combined orthodontic-surgical treatment of patients with severe malocclusions and the early treatment of newborns with cleft lip and palate and is responsible for the orthognathic surgery and the cleft treatment in the Department of Orthodontics. After visiting many renomated cleft centers worldwide, he introduced "Nasoalveolar Molding" into the interdisciplinary protocoll of the Cleft Center of the University Clinic of Bonn, a technique which concentrates on the reduction of the cleft deformity and molding of the lip/nose region before the first operation, allowing superior surgical results.

He is an active professor for undergraduate dental students and postgraduate orthodontic residents and is an official examiner in the state dental examination. He regularly holds lectures in national and international meetings and congresses.
