ONE–PHASE VS. TWO–PHASE TREATMENT
The difference between treating a patient in one phase versus two phases of orthodontic treatment is the increase in cost and additional appointment visits required. University research and collaboration with orthodontic study clubs has verified this. In the 1980’s, 40% of the orthodontic patients were treated with two phases, but now it is only 10%. Thus, if the orthodontist can give the patients the same excellent results incurring less expense and requiring fewer appointments, then two-phase treatment is not for your child.
During the beginning years of Dr. King’s career, two-phase treatment was utilized until the research, his clinical observations, and orthodontic technological advances allowed Dr. King & Dr. Welch to treat the same patients with one phase.
