Participants will wear a passive fabricated from unchanged digital models and not intended to move teeth or provide orthodontic treatment.
The aligner will be worn full-time for 14 days, followed by a 48-hour washout period before the next system, with digital intraoral scans obtained at baseline, 24 hours, 7 days, and 14 days to assess aligner adaptation and trueness over time.

Foranstaltningsbeskrivelse |
Tidsramme |
|---|---|---|
|
Aligner-tooth adaptation (3D gap distance) for each clear aligner system, with and without attachments.
Tidsramme: Up to 14 days of wear for each aligner system (assessed at baseline, 24 hours, 7 days, and 14 days).
|
Mean 3D distance (millimeters) between the inner surface of the passive clear aligner and the corresponding tooth surface, computed from superimposed digital intraoral scans at baseline, 24 hours, 7 days, and 14 days of wear for each aligner system, comparing attachment and non-attachment groups
|
Up to 14 days of wear for each aligner system (assessed at baseline, 24 hours, 7 days, and 14 days).
