Over 20 years of clinical experience in orthodontics using various treatment techniques including Tweed-Merrifield edgewise philosophy, MEAW therapy, and contemporary fixed appliance systems. Known for systematic diagnostic approach and precise mechanics for complex malocclusion correction including vertical dimension control, deep bite correction, and open bite management.

Certified instructor for Tweed Course, Seoul, South Korea. Certified instructor for MEAW International Course, Seoul, South Korea. Certified graduate of the Summer School of Orthodontic Biomechanics, Viareggio, Italy. International lecturer presenting on edgewise orthodontic techniques, MEAW mechanics, and comprehensive treatment planning. Regular participant in continuing education programs in South Korea, United States, Italy, and Spain to stay current with evidence-based orthodontic protocols.

DDS. Certificate in Orthodontics. Residency and advanced training completed in South Korea, United States, Italy, and Spain.

Orthodontist in private practice, inventor, and pioneer of 3D metal printed orthodontic appliances. Private practice, Belp, Switzerland. Honorary Lecturer, University of Sydney, Australia. Faculty Member, University of Maryland, USA.

Beginning in 2014, Dr. Graf developed the first fully digital protocol for fabricating metal orthodontic appliances — starting with the Hyrax rapid palatal expander — directly from intraoral scans using CAD/CAM design and selective laser melting (SLM/3D metal printing), with no physical impressions or stone models required. He subsequently extended the technique to the Herbst appliance, lingual arches, bone-borne expanders, habit-breaking appliances, and custom bracket systems.

Co-author (with Nour E. Tarraf and Neal D. Kravitz) of multiple peer-reviewed publications on 3D metal printed orthodontic laboratory appliances, including articles in the Journal of the World Federation of Orthodontists. International lecturer on digital orthodontics and 3D printing; speaker at major congresses including the AAO Annual Session and SFOPA Congress 2025 (Marseille).

BDS(Hons), MDSc(Hons), PhD,  MOrth RCSEd, MRACDS (Ortho) 

Nour finished his BDS at Cairo University with Honours in 2001 followed by an orthodontic residency at Cairo University.  He then moved to Sydney where he completed his master’s degree in Orthodontics at the University of Sydney in 2008 with Honours.  

He works in private practice in both Chatswood and St Ives, Sydney and is involved in research and teaching at the University of Sydney. Nour has a special interest in invisible orthodontic techniques such as lingual orthodontics and Invisalign.

He is the past president of the Australasian Society of Lingual Orthodontics. He is also the first and only Australian to become a Titular member of the European Society of Lingual Orthodontics and an Active member of the World Society of Lingual Orthodontics.  

Among his special interests are the use of digital technology in orthodontics, early orthodontics and growth modification treatment and he recently completed a PhD on the application of skeletal anchorage in maxillary growth modification for growing children.

He has lectured nationally and internationally and has number of scientific publications. 

In his free time Nour like to spend time with his daughters Hana and Maryam. He loves sport and after years of doing triathlon has taken up the new challenge of Nordic biathlon in the winter.
