Dr Tarraf was invited to the 7th Benefit System TAD users meeting in Duesseldorf, Germany, to share his experience and technique in using the system for jaw expansion and correction of severe underbite problems. Dr Tarraf presented on the modification he has applied to the system in Sydney and presented his technique for effective management of severe underbite problems in growing children. The technique allows correction of severe upper jaw narrowness and deficiency and may prevent or reduce the need for extensive jaw surgery in the future. Dr Tarraf was one of 8 international speakers and said the meeting was a fantastic learning experience with over 250 attendees from 28 countries. It was a great opportunity to learn about the latest updates in the system and we have already purchased the latest technology so we can continue to provide our patients with state of the art treatment.
