Trimming questions

1. Why do your aligners overlap the gumline?

As we announced in September, we now trim our aligners with a smooth contour, overlapping the attached gingiva. We made this change based on clinical research which demonstrated big improvements to retention using this technique.

2. Can I make custom trimming requests?

Unfortunately, we are not able to accept custom trimming requests. We trim all aligners using the same standard protocol. If you want to customize your aligners, you can do so fairly easily in your office with a buffing wheel (like the ones available in our online store).

3. What should I look for if my patient complains of sore gums?

ClearCorrect aligners go through a multi-stage polishing process, so actual rough or sharp edges should be quite rare.

It is fairly common, however, to experience some discomfort for the first few days wearing an aligner. This often indicates that the soft tissue is getting used to having foreign material present in the mouth. Changes to the mucosa eventually fade away when the patient stops wearing aligners.

If the gums are being impinged, one possibility is that the gingiva were not captured accurately in the impression. We prefer 4-5 millimeters of gum to be included. Incomplete impressions will affect our production models.

Frenum_pullYou may also want to look for frenum pulls. These can be difficult to detect because the aligner may feel comfortable at first, but as the patient speaks and moves around, the frenum becomes irritated and ulcerated. Unfortunately this dynamic movement is not captured in the impression. Clear photographs can help to identify these. Gingival frenum pulls are rare, but when they occur, they are typically found in the maxillary premolar and midline areas. If this proves to be a problem, you may want to trim the aligner shorter in the affected areas.
