The verification step or verification key is a unique, hard acrylic aligner that is used by the doctor to help check the compliance of the patient.  This tool is normally included after the 8th step in the treatment in a typical set of 10.

This aligner is made of a thicker material and is also slightly shorter, and it will be clearly marked on the packaging as different from the normal trays used by the patient.  It is not meant to be sent home with the patient, but is kept in the office and used by the doctor to check how the treatment is progressing.  If the verification key does not fit properly, it can be used to have conversations with the patient about the importance of compliance, and the impact of failing verification on the successful resolution of their treatment plan.

What should I do if the verification key doesn't fit?

Imagine your patient comes in to your practice at a checkpoint and the verification key doesn't fit. I might look like this:

Good news! You do not worry too much if the verification key doesn't fit. It's entire purpose is to find problems before they start. Now, we can rely on our ability to control the treatment; here's how:

Just send a picture and we will suggest one of the three ways of self-refining during the treatment and keeping control over the progress.

1) Fast-forward. With Orthosnap's treatment plan, we do not address all teeth simultaneously; we are addressing two or three teeth and taking advantage of anchoring techniques. So, fast forwarding to the next step is an option when there is a slight tracking issue.

2) Use the verification key as a rescue device. The verification key has a second purpose. You can have the patient wear the verification key for the next two nights, and then have them wear the next set of aligners; pretty simple.

3) Update the treatment plan before producing the next order of aligners. With our order segmentation, we do not produce all the aligners at one. Working through the treatment in stages allows us to change the future plan and keep a predictable outcome.
