  • Patent number: 11253340
    Abstract: A method of monitoring the degree of fit of an aligner among a series of aligners includes the steps of selecting an aligner in the series of aligners whose fit to a patient's teeth are to be tested to determine its fit with the selected aligner; disposing a nontoxic colored plastic material into the selected aligner; setting the patient's teeth into the selected aligner containing the material; and determining the amount of material disposed onto the interior aligner's surfaces by visual inspection by assessment of the material disposed therein, a good fit being indicated by a minimum of material extruded onto almost all of the interior aligner surfaces and by a light color, and a poor fit being indicated by an excess of material extruded onto one or more locations of the aligner interior surfaces and a dark color.
