ClinConnect Summary

This prospective clinical trial aims to determine whether replacing an aligner after 7 days with a new aligner of a different material affects the predictability of planned dental movements. A total of 114 adult patients undergoing orthodontic treatment with aligners-requiring bilateral tooth movements (extrusion, intrusion, rotation, tipping, or mesiodistal translation)-will be recruited and randomized into three groups with distinct aligner exchange protocols.

Group 1: 10 days of exclusive FLX aligner use. Group 2: 7 days of FLX aligner use followed by 3 days of FLX35 use. Group 3: 7 day...
