Quad-Helix

Quad-Helix Appliance
The Quad-Helix Appliance is an orthodontic device designed for the expansion of the upper dental arch. It is particularly effective in cases where there is a need to widen the upper jaw, correct bite issues, or alleviate crowding in the upper arch. The appliance is commonly used in both pediatric and adult orthodontic treatments, depending on the severity of the issue being addressed.

Key Features:

Attached to Molar Bands: Similar to other arch expansion appliances, the Quad-Helix is securely attached to the first molars using metal bands. These bands serve as the anchor points for the appliance, providing stability and ensuring that the forces applied by the springs are directed precisely where they are needed.

Wire with 4 Active Helix Springs that Widen the Arch of the Mouth: The Quad-Helix appliance features a wire with four active helix springs. These springs, two on each side of the upper arch, provide active force to gently widen the dental arch. The four helixes allow for more controlled and gradual expansion compared to appliances with fewer springs, making this a versatile device for addressing moderate to severe arch constriction. The springs expand the arch symmetrically, which can help with both dental and skeletal issues, depending on the case.

Lingual Wires that Extend Mesial to the Cuspids: The Quad-Helix has lingual wires positioned along the inside of the dental arch. These wires extend to the mesial of the cuspids (canine teeth), ensuring that the appliance exerts force across the entire upper arch. The extension to the cuspids helps guide the proper alignment of all the teeth, not just the molars, leading to more balanced and effective expansion and alignment of the upper arch.

The Quad-Helix Appliance is typically used when there is a need for more significant arch expansion compared to other devices like the Bi-Helix. It is effective for addressing crossbites, narrow upper arches, and even mild to moderate crowding. Its design with four helix springs provides powerful, consistent expansion forces to create the space needed for proper alignment.
