Official Title: Colorimetric Stability of Finishing Clear Aligners According to Marginal Termination Design (Supragingival Versus Juxtagingival) After 14 Days of Intraoral Wear During Orthodontic Treatment: A Prospec

Brief Summary: * The goal of this clinical study is to learn whether the gumline edge design of a finishing orthodontic clear aligner affects how much the aligner's color changes after 14 days of wear.* The main question is: does a supragingival edge design - a straight edge covering about 2 mm of gum tissue - lead to a different amount of color change in the aligner compared with a juxtagingival edge design that follows the gumline exactly, after 14 days of wear?* Each participant wears finishing clear aligners with both edge…
