ClinConnect Summary

This clinical trial is looking at the best way to attach the wire to braces during a specific part of orthodontic treatment called canine retraction, where the pointed canine teeth in the upper jaw are moved backward to close gaps created by removing other teeth. The study compares three different methods of tying the wire to the braces to see which one helps the canine teeth move the right amount, while also minimizing unwanted movements like twisting or tipping, and preventing the back molars from shifting forward too much.

If you are 16 years or older, need to have one or both upper first premolars removed as part of your orthodontic treatment, require at least 4 millimeters of canine movement, have good oral hygiene, and will use a special device called a Nance appliance to keep your back teeth stable, you might be eligible to join. Participants will have a thorough dental exam, get braces and other appliances fitted, and have regular check-ups every four weeks where 3D scans of the teeth are taken. The canine teeth will be moved using elastic chains with a gentle, controlled force. Even after the study measurements are done, participants will continue their full orthodontic treatment until complete. This study aims to find the most effective and safe way to tie braces wires during this important phase of treatment.
