5 midcourse correction myths

There are a lot of misconceptions out there about refinements & midcourse corrections. Here are some of the most common misunderstandings:

Myth #1: You can get unlimited midcourse corrections & refinements for free.

False. It is true that we don't charge a fee for refinements or midcourse corrections. However, you're still only entitled to receive the number of phases included with your case (3 for Limited, 8 for Full). If you use more than that, you'll have to pay for the extra phases. You're also responsible for the cost of shipping new impressions to us.

Myth #2: You should request a midcourse correction every time an aligner doesn't fit.

False. Most of the time, if the teeth aren't on track, it's because the patient hasn't been wearing the aligners regularly. The aligners really need to be worn 22 hours a day, every day, for best results. If your patient isn't doing that, then requesting a midcourse correction is a complete waste of time. 

Remember what a midcourse correction is: we simply make a new phase starting from the current position of the patient's teeth. You can accomplish the same thing without wasting a phase by simply backtracking to the last step that fit and reinforcing the wear schedule. For extra strength, you can make fresh aligners using the included dental models. Of course, use your professional judgement, too. If there's a difficult extrusion or intrusion that's not happening, a bracket & auxiliary technique will often be more effective than a midcourse correction.

Myth #3: You'll get a Phase Zero and treatment setup after a midcourse correction.

False. As the name implies, Phase Zero is only sent at the beginning of treatment. A midcourse correction does not change the ultimate goal for the case, so we don't generate a new setup for your approval.

Myth #4: Your patient should stop wearing aligners while waiting for a midcourse correction.

Myth #5: Your patient should keep advancing to new steps while waiting for a midcourse correction.

False and false. When you submit a midcourse correction form, we'll ask "Which steps currently fit your patient's teeth best?" Those are the aligners your patient should keep wearing to retain the position of their teeth. When you get the revised phase, give the first included step to your patient and discard any unused steps from the previous phase.

As always, if you have any questions, just ask your account rep.
