At -10ºC degrees, but ready to work and with a whirlwind of ideas and knowledge packed in his suitcase, Dr Perera travelled to Lithuania last weekend to give an advanced course on the Damon System. At the end of the course, Dr Antanas Sidlauskas, university professor and director of the Master's Degree in Orthodontics at the University of Kaunas, presented Dr Perera with a diploma officially accrediting the course. This was an honour coming from another professional from the sector who is dedicated to research and the application of 3D technologies in diagnosis and orthodontic treatments. So, with the wheels of his suitcase still in the process of thawing out, Dr Perera has hurried to share these photos of his visit with all of us.
