Who is ACAS?

ACAS (Australasian Clear Aligner Society) started as a dream in May 2018. A society of like minded Orthodontists, Dentists and Therapists passionate about clear aligners. This materialised as a vision that the fundamental principles of clear aligners are universal to any aligner system and can be learnt autonomously and impartially.
