What is it indicated for?

The Krystal Klear Aligners System is intended to correct minor discrepancies in the alignment of maloccluded anterior

teeth on patients with permanent dentition (second molars) by moving the teeth with a progressive series of clear thin,

thermoformed plastic aligners, fabricated in stages to gradually align teeth over a period of several months. The aligners

are completely removable by the patient and may be discontinued at any time.

Indications for use read by OCR from a scanned FDA summary, so letters may be misread. Check the PDF before quoting it.
