Activated omega loops for anterior crossbite correction in transitional dentition

Area of Science:

• Orthodontics
• Dental Arch Development

Background:

• Pseudo-Class III malocclusion requires correction during transitional dentition.
• Existing methods like the "two by four" appliance, open-coil springs, and Class III elastics have drawbacks, including soft tissue injury and undesirable tooth movements.

Observation:

• Conventional treatments for pseudo-Class III malocclusion can lead to complications such as soft tissue lacerations, flattened smile lines, and excessive proclination of upper incisors.
• Class III elastics may cause counterclockwise rotation of the occlusal plane and affect maxillary incisor display.

Findings:

• A novel orthodontic approach is described to correct pseudo-Class III anterior crossbite.
• This technique specifically targets the lingual tipping of lower incisors to establish a normal overjet.
• The method avoids compromising the position or aesthetics of the upper dentition.

Implications:

• Provides a potentially safer and more effective alternative for correcting pseudo-Class III anterior crossbite.
• Offers a method that preserves upper incisor aesthetics and avoids common side effects of other treatments.
• Contributes to improved treatment outcomes in pediatric orthodontics.
