24th International Orthodontic Symposium (IOS 2022)

Besides his clinic, Simon Graf, is developing new possibilities to integrate up-to-date technology in the orthodontic field. He started in the beginning of 2014 with a cad/cam-procedure for 3D-metal- printed rapid-palatal-expansion device(hyrax) directly from an intraoral scan. As soon he was able to establish a standardized protocol for this appliance, he continued to work on the herbst-appliance, lingual arch etc. and proceeded to bone-borne appliances. As the materials are evolving, he is now working on acrylic direct printed removable appliances, with the idea to simplify the orthodontic daily business. Also, he is involved in the development of self-designing appliance software. He is lecturing about these topics since 2016 worldwide.

Björn Ludwig is an orthodontics specialist who operates his private office in a small village in Germany.

He holds positions at two universities: the University of Homburg/Saar in Germany and the Department of Orthodontics, Institute of Odontology, Sahlgrenska Academy, University of Gothenburg, Sweden.

While his primary focus is on clinical work, he has a strong affinity for technology, which consistently sparks his interest.

He is dedicated to advancing as a researcher and writer, actively participating in a variety of research projects and taking on editorial roles for academic journals.

Furthermore, he serves as an editor for several books and is the author of numerous book chapters in classic orthodontic texts.

In addition to his passion for orthodontics, he also takes pleasure in cycling as a means tounwind.

Ralf J. Radlanski is Director of the Department of Craniofacial Developmental Biology at Charité, the Center for Dental and Craniofacial Sciences. As an anatomist, an internationally esteemed scientist, and as a practicing orthodontist, he works at the interface between biology-anatomy on the one hand and esthetic clinical requirements on the other, a crucial area of interaction in many clinical disciplines.
