Modified quad helix appliance for thumb sucking and cross bite correction

Area of Science:

• Dentistry
• Pediatric Dentistry
• Orthodontics

Background:

• Digit sucking is a common childhood habit.
• Persistent digit sucking beyond preschool age can lead to malocclusion, including anterior open bite, maxillary constriction, and posterior crossbite.
• Interception of the habit and correction of malocclusion are key treatment strategies.

Observation:

• A 9-year-old child presented with a persistent thumb sucking habit.
• The child also exhibited a posterior crossbite, a type of malocclusion.

Findings:

• A modified quad helix appliance was successfully used to intercept the thumb sucking habit.
• The appliance also achieved simultaneous correction of the posterior crossbite.
• This modified appliance demonstrated ease of fabrication, versatility, and improved patient compliance.

Implications:

• Modified quad helix appliances offer an effective and patient-centered approach for managing digit sucking habits in children.
• Early intervention can prevent or correct malocclusion, promoting better oral health outcomes.
• This appliance design presents a practical solution for clinicians treating pediatric dental issues.
