The Effect of Timing on Orthodontic Treatment

The aim of this longitudinal randomized investigation is to determine the long-term effects of early headgear treatment on craniofacial structures and dental arches, compared to treatment started later, during the most active growth period in Class II patients. The aim was further to find out the possible benefits and the burden of early treatment to the patients and parents of these common malocclusions, when compared to groups treated later, but with the same methods as much as possible. The hypothesis is that the timing of treatment has significant effects on orthodontic treatment total time, the general outcome of the treatment, and the compliance of the patient.
