Three groups of Class II/I patients were compared where treatment was carried out using Begg, Andresen and removable appliance techniques. Skeletal growth, as assessed by the dimensions S-Me, N-Me, ALFH and Me-Ar did not show any difference between the groups. All three groups showed an apparent improvement in skeletal pattern during treatment.
