Dr Chris Orloff

BDS (Lond), LDSRCS (Eng), MDSc (WA) Orth, MRACDS Orth, Grad Dip DSM (UWA)

Dr Chris Orloff is a dental graduate of Kings College School of Medicine and Dentistry (1989). In 1992, in a quest for something different, he and his wife Sarah moved from the leafy towns surrounding the River Thames to the dry remote outback town of Coober Pedy. While in Coober Pedy, Chris and Sarah enjoyed the wide open spaces, Chris’ varied career as a General Dentist and a little Opal Fever, mining underground in their spare time! They enjoyed this experience so much they decided to stay in Australia.

In 1996, Dr Chris was accepted for the orthodontic training programme at UWA, so they packed everything up again and travelled across the Nullarbor with their new baby to commence a new life in the northern beachside suburbs of Perth.

The orthodontic training programme at UWA is a three-year, full-time course which required Dr Chris to work weekends and evenings as a dentist to pay the bills, while stealing time whenever possible to spend with their infant daughter Hannah.

On completion of the training programme, Dr Chris was awarded a Master of Science in Orthodontics and later was conferred Membership in the Royal Australian College of Dental Surgeons. 

Dr Chris worked in various positions as a specialist orthodontist before establishing Class 1 Orthodontics. Class I Orthodontics’ first clinic in Kalgoorlie opened in 1999. Rockingham followed in 2002 and the Class 1 Orthodontics name has grown from there. Since the expansion of Class 1 Orthodontics and the birth of their second daughter Maya, Dr Chris has worked tirelessly to bring modern, time-saving orthodontic techniques to the WA family practice he established.

Invisalign changed the world of orthodontics by creating the first digital patient-specific orthodontic technique with customisation for every patient. He believes the future of orthodontics is customised to each person, achieving excellent results but also simultaneously reducing the need for so many disruptive appointments affecting school and work schedules.

Dr Chris has not neglected his obligation to the profession of orthodontics, serving two-year terms as both State Treasurer and State President of the Australian Society of Orthodontists (WA Branch). He is currently a member of the Australian Dental Society and the American Association of Orthodontists.

Over the years Dr Chris has developed an interest in the impact of Sleep Disordered breathing in both children and adults and has successfully completed a Graduate Diploma in Dental Sleep Medicine at UWA.

He currently holds a position as Honorary Research Fellow in the School of Anatomy, Physiology and Human Biology. His current research projects are clinical investigations into the effects of Invisalign aligners and tele-dentistry.

Despite a very busy and rewarding professional career, Dr Chris still manages to get away from it all. His interests are boating and diving, and his growing herd of lively alpacas!
