My treatment plan showed green dots (Compliance Checkpoints) between teeth 12 and 13. When I flossed between those teeth, there was no contact. Now what?
When the contact hasn't fully closed at a Compliance Checkpoint, it doesn't necessarily mean that the case is hopelessly off-track. If the aligners still seem to be fitting, you can just keep an eye on that area and continue with the treatment.
The IPR performed in that area may have been larger than recommended, your patient may not be wearing the aligners for 22 hours a day, or the teeth may just not be tracking as intended.
The most common issue is patient non-compliance, so that's the first thing to investigate. Make sure that your patients understand how often they need to wear the aligners.
If the treatment plan recommends IPR in a spot where the teeth are not touching each other, wait to perform it until that area closes.
When you move on to the next step, make sure that the other teeth in the vicinity of the Compliance Checkpoint are tracking properly.
If the aligners eventually stop fitting, then you'll probably need to take new impressions and request a midcourse correction.
If the problem doesn't resolve itself by the end of treatment, you can request a refinement to close all of the spaces with a "digital power chain."
Hopefully, you won't run into this issue too often. That's it for this week.
Until next time...
