Comparing the effectiveness of clear aligners with different attachments for tooth rotation
A Randomized Clinical Trial to Compare the Influence of Optimized Attachments, IPR and a Combination of Both Techniques on the Rotational Accuracy of Canines With Clear Aligners
This study is testing if using different types of attachments with clear aligners can help improve the rotation of canine teeth for people getting orthodontic treatment.

What this trial studies
This clinical trial evaluates how optimized attachments and interproximal reduction (IPR) affect the rotational accuracy of canines when using clear aligners. Participants will be randomly assigned to one of four groups, each receiving a different treatment approach. Initial orthodontic records will be collected, followed by the delivery of aligners after five weeks. The study will conclude with the collection of final records to assess the accuracy of the treatment outcomes by comparing predicted and achieved results.
Who should consider this trial
Good fit: Ideal candidates are healthy adults over 18 with rotated canines requiring derotation and who can commit to wearing Invisalign aligners.
Not a fit: Patients with poor oral hygiene, craniofacial anomalies, or those requiring surgical intervention or extraction treatments may not benefit from this study.
Why it matters
Potential benefit: If successful, this study could improve the effectiveness of clear aligners in correcting tooth rotation, leading to better orthodontic outcomes.
How similar studies have performed: While there have been studies on clear aligners, this specific approach comparing optimized attachments and IPR is relatively novel.
