On 12^th May, Dr Perera gave a course on the Damon System in Zaragoza during which those attending had the opportunity to increase their knowledge of the technique and to learn about the finer details of working with self-ligating brackets and the Damon System.
 

He did this on a course presented by Doctor Daniel Aragón which was held at the Official College of Dentists of Aragon. This was a limited-numbers course organised by Ormco in which Dr Perera addressed many questions of interest relating to this revolutionary technique.
