3 Common Invisalign® Mistakes (And What to Do Instead)

by / Friday, 25 March 2016 / Published in Blog


Invisalign® and other types of clear aligners are a great treatment option for certain patients who want straighter teeth. Many doctors offer this service because patients want it and it’s relatively easy to become trained and start offering the service right away. Unfortunately, it’s also common to make costly mistakes with clear aligners, especially when you are just starting out with the treatment.

We put together this quick list of the common mistakes we’ve seen doctors make with clear aligners, and what you can do to avoid making these errors in the future.

1. Allowing the technician to dictate the treatment plan

Invisalign cases should be diagnosed and treatment planned by you, the doctor. It is your job to tell the technician how to move the teeth on the ClinCheck®.

Unfortunately many doctors do not do a review of the ClinCheck they get back, or know what to look for. They may see teeth straightening and think this will make a successful finish. At the end of treatment, patients should not only have straight teeth, but also have a full smile with good function, so you must be diligent in setting up the right design.

When you get the ClinCheck back, we suggest you look at some diagnostic items like your patients’ curve of spee, teeth width and esthetics, and spacing, to ensure that the appliance is set up correctly. You should also look at each arch individually so that you catch any missed spaces or teeth going to erupt. Customizing the appliance enables you to best fit your patients’ case goals and avoid excessive spacing, unexpected crowding, immobile teeth, or unaesthetic finishes. For this reason, we recommend that a ClinCheck should never be approved the first time around.


2. Not checking for tight contacts when teeth are moving

Many doctors may not realize that adding force when there’s no space can affect more than just tooth rotation. If the contacts are tight and the aligners add new force, teeth will not have room to move as expected and will end up intruding. Check contacts at the chair every appointment to avoid this unaesthetic mistake.

3. Failing to understand how the appliance works

Because the software makes set up so easy, many dentists forget to think about the forces they’re applying when providing aligners. Dental principles and treatment planning should still be addressed.

Before approving the appliance, think how the teeth should move during treatment at how they should fit together in your patient’s face at the finish. If you’re using an attachment, you should understand the movement the tooth should have and the adequate velocity and force needed. Don’t forget to properly diagnose and treatment plan your aligner cases, because you control the success (or not) of your results.


Keep these suggestions in mind for your next clear aligner case. We hope that you can avoid these typical pitfalls so that your Invisalign treatment stays easy and profitable. With practice and diagnostic skills, you will become confident and successful.
