Summary

the PowerScope appliance is found to be efficient for the treatment of class II malocclusion. Accordingly, it appears valuable to investigate the efficiency of skeletally anchored powerScope in the treatment of class III malocclusion

Detailed description

The PowerScope is the latest innovation in the treatment of Class II malocclusion which is a direct derivative of the Herbst Type II appliance. Dr. Andy Hayes worked in conjunction with American Orthodontics to develop PowerScope in 2016. This appliance supports intermaxillary wire-to-wire installation via a nut and hexagonal screw. A ball and socket joint is used to maximize lateral movement while improving patient comfort. The appliance is made up of a telescopic mechanism made up of an inner shaft/push rod, middle and outer tubing, and a spacer between the middle and outer tubing. A nickel-titanium (NiTi) spring provides a constant 260 g force. According to the present knowledge no studies regarding treatment outcomes of comprehensive fixed appliance treatment combined with the PowerScope in Class ΙII patients have been reported. The introduction of temporary anchorage devices (TADs) has made it possible to achieve absolute anchorage control in daily clinical orthodontic practice when used in conjunction with fixed functional appliances. However, it appears that there is no evidence in the literature supporting the clinical effectiveness of miniscrew- anchored fixed functional appliances for the treatment of Class III malocclusion. According to the current available literature, the PowerScope appliance is found to be efficient for the treatment of class II malocclusion. Accordingly, it appears valuable to investigate the efficiency of skeletally anchored powerScope in the treatment of class III malocclusion.
