On Friday 27^th April, Dr Perera travelled to Germany as an invited speaker to give an advanced course on the Damon System at the University of Würzburg, one of the most prestigious universities in the country. In it, he explained his evolution from conventional mechanics to the Damon System, a technique which the majority of the doctors attending the course already use. The course also counted on the presence of the interpreters Gabriela and Astrid, professionals with whom Dr Perera has previously shared a hall at other conferences given in Germany, and the group from Ormco Deutchland, who also feature in the photos that we are sharing with you.
