Jochen Peter Winkelstroeter retired from the management team and the company name was changed from Dentaurum J. P. Winkelstroeter KG to Dentaurum GmbH & Co. KG. The fourth generation, Mark Stephen Pace, Axel Winkelstroeter and Petra Pace, now controls the owner-managed family company. The group employs 500 persons in Germany, and 650 across the world. In 2011 Dentaurum celebrates the 125th anniversary of the company. To keep the tradition alive the founder is commemorated by the Arnold Biber Prize, sponsored by Dentaurum since 1910, which honours scientific work in orthodontics. The recipient of the Arnold Biber Prize is selected by a committee of the German Society for Orthodontics.
