Evaluation of IPR and Attachments on Rotational Tooth Movement in Clear Aligner Therapy

Summary

This study is testing whether clear aligners (Invisalign®) can help fix teeth that are rotated. The researchers want to learn if using two common methods-interproximal enamel reduction (IPR) and attachments-makes rotation correction more successful.

Participants in the study will wear custom-made aligners for about 20 to 22 hours every day. They will switch to a new set of aligners every 2 weeks.

The study will look at tooth movement over time by using a digital planning tool called ClinCheck®, which helps plan and measure how much teeth have moved.

The researchers want to answer three main questions:

Do Invisalign® aligners work well for correcting rotated teeth?

Does IPR help improve rotation correction?

Do attachments help improve rotation correction?

The goal is to understand whether these tools work better together or separately to move teeth into better alignment.
