The purpose of this case report was to investigate the clinical effectiveness in reducing large overjet with an Andresen activator, a cheap and effective appliance for growing patients cases. Treatment with Andresen appliances showed a higher reduction for the ANB angle. Conclusions: the period of orthodontic treatment was reduced because the peak of bones’ growth occurred concomitantly with the eruption of the second molar.
