ClinConnect Summary

This clinical trial is studying how the size of clear aligner attachments affects the movement of the upper side teeth known as maxillary lateral incisors during orthodontic treatment. Clear aligners, like Invisalign, are a popular alternative to traditional braces because they are more comfortable and less noticeable. The trial aims to understand if different attachment sizes can improve the way these specific teeth move, which is important for achieving the best results in orthodontic treatment.

To participate in the trial, individuals should be at least 12 years old and currently undergoing Comprehensive Invisalign or Invisalign Teen treatment. They must have a certain amount of space between their teeth and meet specific requirements for their maxillary lateral incisors. Participants should also be committed to wearing their aligners as directed throughout the study. Those who join can expect regular check-ins and assessments to monitor their progress. This trial is currently recruiting participants, so it's a great opportunity for those looking to optimize their orthodontic experience with clear aligners.
