A tele-roentgenological longitudinal examination in 46 patients suffering from mandibular retrognathia analysed over a period of 2.35 years the development within the range of their facial skeleton. 24 patients had been treated by the regulator of function acc. to Fränkel, 20 patients by means of activators. Compared with the activator-treated group, the group treated by regulators of function offered an improved sagittal development of the lower jaw, an increased forward rotation of the lower jaw and a stable development of the lower region of incisors.
