For most of us, the meteoric impact of Aligners on the stable world of orthodontics two decades ago will be vividly remembered.

A new, revolutionary therapy, born of economic interests and made possible via the digitisation of orthodontic processes, began to disrupt the order of orthodontists. Many rejected this new form of therapy, some worked with it and developed it further. After two decades, we know that many Aligner treatments are possible in the same way as treatment with fixed appliances.
