Dentist, University of Bern (2007); Postgraduate program, orthodontic department of the University of Basel (2012); Simon Graf has a specific interest in the production of orthodontic appliances in the digital world. He started in early 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 have been evolving, he is now working on acrylic direct printed removable appliances. Also, he is involved in the development of self-designing appliance software. Since 2016, he has been lecturing worldwide about these topics. Dr. Graf also has a private orthodontic clinic in Belp, Switzerland.
