Abstract: 
The purpose of this investigation was: (1) to analyse the efficiency of 5 mandibular anchorage systems in Herbst treatment and (2) to ascertain if recovery in lower incisor tooth movements after treatment resulted in anterior crowding. The sample consisted of 65 Class II, division 1 malocclusions treated with the Herbst appliance for an average period of 7 months. The patients were re-examined 6 and 12 months post treatment. The following mandibular anchorage systems were utilized: (1) Premolar anchorage (n = 16), (2) Premolar-Molar anchorage (n = 20), (3) Pelott anchorage (n = 6), (4) Labial-Lingual anchorage (n = 10) and (5) Class III elastics (n = 13). The method comprised an analysis of mandibulr tracings from mouth open profile roentgenograms and mandibular dental casts. The results revealed that none of the 5 anchorage systems used in Herbst could prevent anterior movement of the mandibular incisors and molars. About 80 per cent of the incisor tooth movements and 20 per cent of the molar tooth movements recovered after treatment tooth position changes were not considered to result in anterior crowding.
