Dr Ngan also teaches Doctorate Orthodontics at The University of Sydney and is an Adjunct Lecturer at Charles Sturt University.

He says, “After 15 years of orthodontics, I have evolved my philosophy to include optimising dento-facial aesthetics on a non-extraction basis where possible. I use all techniques including self ligating brackets, functional and expansion appliances, and mini implant techniques. I also have more than 13 years of experience using Invisalign".

“I have been a partner at Orthodontics Exclusively for over 20 years. We are all actively involved in University teaching (personally since 1992) and the sharing of ideas allows us to stay at the forefront of the development and provision of Specialist Orthodontic Care including invisible braces for adult patients and non-extraction therapy for our younger patients. Creating beautiful, healthy and natural smiles is why I enjoy my work so much.”
