Dento-facial changes during stage 1 orthodontic treatment with the Begg appliance

Observes the dento-facial changes of Class II division I malocclusion patients treated by Begg appliance from pre-treatment until stage 1 and rejects the null hypothesis that treatment responses are independent of face types. Concludes that each face type (short, average, and long faced patients) responds differently to the Begg treatment stage I.Thesis (M.D.S.) -- University of Adelaide, Dept. of Dentistry, 1996
