title: Orthopaedic protraction of the midface in the deciduous dentition. Results covering 3 years out of treatment.
abstract: If there is underdevelopment of the upper jaw, the current Bergen concept indicates a period of orthopaedic/orthodontic treatment of cleft lip and palate patients at 6-7 years of age. A fixed quad-helix-appliance is used in combination with a facial mask. The result is retained with a fixed palatal arch. A preliminary follow-up study on sagittal growth and development in 30 patients is reported. By treating early, a more basal response is obtained, and several years of more correct function is gained.
