Clinical Trial: Marginal Biofilm Distribution and Periodontal Response to Supragingival and Juxtagingival Aligner Designs

U.S., June 12 -- ClinicalTrials.gov registry received information related to the study (NCT07642037) titled 'Marginal Biofilm Distribution and Periodontal Response to Supragingival and Juxtagingival Aligner Designs' on June 06.

Brief Summary: * This prospective, longitudinal, within-person (split-mouth) clinical study evaluates the influence of two clear aligner trimming-line designs on marginal soft-tissue biofilm distribution and periodontal tissue response over a six-month period.

* Two trimming-line designs are compared. The supragingival design has a straight, horizontal edge that extends approximately 2 mm onto the marginal gingiva, resting in direct contact with the gingival surface but not entering the gingival sulcus. The juxtagi...
