Dr Derek Mahony is an orthodontist and advocate of interceptive orthodontic treatment. Learning from leading clinicians the dramatic effect functional appliance therapy can afford patients in orthodontic treatment, he has been combining the fixed and functional appliance approach ever since. His lectures are based on the positive impact such a combined treatment approach has had on his orthodontic results and the benefits this philosophy provides from a practice management viewpoint.
