This preventive orthodontic technique is applicable for the 5- to 7-year-old to prevent problems involving crowding, spacing, rotations, overbite, overjet, gummy smiles, Class II molar relations, and TMJ dysfunction from developing. The technique is based on accepted published research on the development of the dentition. Patients are typically started at 5 or 6 years of age and wear two preformed appliances only while sleeping. The active stage lasts about 2 years. The same appliance is used as a retainer until 12 years when the patient is dismissed About 75% to 80% do not require further orthodontics. The total procedure takes about 2 to 3 hours of total chair time.
