Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are adults aged 15-20 with mild Class II division 1 malocclusion and moderate overjet.
✕Probably not a fit
Patients with periodontal disease, vertical growth patterns, or severe skeletal Class II malocclusion may not benefit from this study.

What this trial studies
This study evaluates the effectiveness of clear aligners with intermaxillary elastics versus traditional fixed multibracket appliances in treating adult patients with mild Class II division 1 malocclusion and increased overjet. Participants will be divided into two groups: one receiving clear aligners and the other receiving fixed appliances. The study will assess changes in skeletal, dental, and soft tissue as a result of each treatment method. The goal is to determine which approach yields better outcomes for patients.
Why it matters
Potential benefit: If successful, this study could provide patients with a more effective and comfortable treatment option for mild Class II malocclusion.
How similar studies have gone: Previous studies have shown promising results for clear aligners in orthodontic treatment, suggesting potential success for this approach.
