Hello Dr Gambroudes. I was wondering if you would please give me your thoughts on the differences between Clearstep and Invisalign? From what I understand of both treatments, one is American and the other is British. I have had a consultation with a dentist who uses Clearstep, with his main reason being that he feels there is more flexibility with Clearstep in terms of being able to have moulds re-created and retainers updated if your teeth don’t move as the computer predicts, and this is not the case with Invisalign? Would you agree with this, and which do you prefer out of the two? Thank you in advance.
