The 17^th Orthodontic Sessions were organised last May by the institution Mississippi-CEU. On this occasion, the event was particularly special as it coincided with the 25^th anniversary of this prestigious institution. A series of invited speakers included Dr Rafael García Espejo, co-director of the Damon Master programme along with Dr Perera. In his talk, entitled “The Damon System: a before and after in orthodontics”, he explained the evolution of this passive self-ligating technique and the new possibilities that it has offered to our society in recent years. It was a wonderful event which, for yet another year, enjoyed the participation of Dr García Espejo.
