Overcoming Clear Aligner treatment Shortfalls - The Scientific Evidence and its Application

Let's look at our most recent evidence, 

Derived from a 14,000 patient database, published in 17 articles in the last 18 months.

Answering-: 

1. How well do digital treatment plans translate into clinical reality?

2. Do we need to customise the supposedly already customised digital aligner treatment plans we receive from aligner companies?

3. What are are apparent limits to current aligner treatment?

and,

Revealing something quite new and scary!

Biography

I have collected a large database of cases (14,000 plus) from 14 experienced orthodontists in Australia, New Zealand and the United States to enable independent research into the efficacy of aligners, which is my primary research interest.
