Evolution of my lingual technique over 30 years

I will explain how and why my technique has evolved into a fully digital straight wire technique. I will explain why this technique is the most accurate to position the brackets and the most reliable to reproduce perfectly on the patient what we have decided on the digital set-up. Its simplicity makes it particularly accessible to beginners and its efficiency make it usable by the lingualist the most demanding.The report of treated cases will show that the difference between labial and lingual technique is becoming thinner even in terms of chair time and treatment time.


Didier FILLION has been practicing lingual orthodontics exclusively for 32 years. He has held courses in Lingual orthodontics around the world  and lectured in all important adult orthodontic congress.
