Evaluating a new orthodontic appliance for correcting molar alignment
Effectiveness of Auxiliary Segmental Lingual Appliances in Leveling the Curve of Wilson at Second Molars
This study is testing a new orthodontic device to see if it can help straighten the back teeth in patients with a deep bite while they are getting braces.

What this trial studies
This study evaluates the effectiveness of auxiliary segmental lingual appliances in leveling the Curve of Wilson at the second molars in patients receiving labial fixed orthodontic treatment. Patients with a deep Curve of Wilson will be recruited and assigned to a split-mouth design, where one side will receive the intervention while the other side serves as a control. Key measurements will include the Curve of Wilson at the second and first molars, as well as the distance from specific cusps of the second molar to the occlusal plane of the first molar. Data will be collected at baseline, after initial leveling, and three months post-intervention to assess the impact of the appliances.
Who should consider this trial
Good fit: Ideal candidates are patients undergoing labial fixed orthodontic treatment with a deep Curve of Wilson at the second molar bilaterally.
Not a fit: Patients with limited mouth opening or a gagging reflex that prevents the placement of the appliances may not benefit from this study.
Why it matters
Potential benefit: If successful, this approach could lead to improved orthodontic outcomes for patients with malocclusion.
How similar studies have performed: While the specific use of auxiliary segmental lingual appliances is novel, similar orthodontic interventions have shown promise in improving molar alignment.
