Three-stage activator treatment of a severe skeletal Class II, open bite malocclusion.
Activator therapy for a severe Class II, Division 1 malocclusion with open bite malocclusion is described. The treatment was performed in three stages: one, "early-early," at the age of 5 to 6 years; one "early," between 9 and 11 years; this was followed by 2 years of retention with a maxillary retainer. The patient continued to be observed further over a 3-year period. The final records show a normal, stable occlusion, and good facial balance.
