Pediatric Airway Orthodontics
Guiding facial and airway growth before problems are set in bone.
What it is
Pediatric airway orthodontics (also called Phase I, interceptive, or growth-guidance orthodontics) is early intervention done while a child is still actively growing. Common appliances include palatal expanders, removable functional appliances such as the Myobrace or twin-block, and habit-correction appliances. The goal is not to perfectly align baby teeth, but to guide the underlying jaw bones, the airway, and the muscle patterns into a healthy developmental trajectory before the growth window closes.
Why we do it
Most of the bony framework of the face, including the airway, completes its development by age 12 in girls and age 14 in boys. Once growth slows, structural changes that would have been simple at age 7 require surgery at age 17. A child with a narrow palate, crossbite, or open bite at age 6 will not grow out of it. Treating early is faster, cheaper, less invasive, and produces results that hold for life. Pediatric airway orthodontics is preventive medicine applied to facial and respiratory development.
What happens during the procedure
Evaluation begins at age 6 to 7. A typical Phase I plan runs 12 to 18 months and might include 3 to 6 months of palatal expansion, 6 to 12 months of a removable functional appliance to encourage forward growth of the lower jaw, and parallel myofunctional therapy to correct mouth breathing and tongue posture. After Phase I the child is monitored every 6 to 12 months until all permanent teeth have erupted, at which point a brief Phase II (often clear aligners) finishes alignment if needed.
Who it’s for
Children ages 5 to 11 with any of the following: persistent mouth breathing, snoring, narrow palate, crossbite, severe crowding, open bite, thumb sucking past age 5, or a family history of jaw surgery. The American Association of Orthodontists recommends an initial orthodontic evaluation by age 7 for every child.
Recovery and what to expect
No recovery. The appliances are well-tolerated within a week. Soreness for two to three days is normal after each appliance change.
