Recently Dr Martin has given a pre-congress course to the Danish Orthodontic Society in Billund, Denmark «the homeland of Lego.» He spoke for two days about the relationship of Occlusion with Temporomandibular Joint Dysfunction. There were approximately 300 attendees and the The course was very successful and there were some very interesting discussions. This is the third time that Dr Martín has been invited to speak in Denmark. I was lucky enough to greet friends and enjoy the Danish landscape.
