Background: Correcting Class II malocclusion with Class II elastics or functional appliances requires great patient collaboration. Here we describe two Class II cases successfully treated with an alternative approach using a fixed device designed to obviate compliance.

However, Class II elastics, like many of these correction devices,
are removable and therefore require great patient compliance, an
influential factor that is difficult to predict before treatment is
begun [5], but one that ideally needs to be taken into account before
the treatment protocol is established

Great interest has therefore been focused on techniques that
minimize the need for patient cooperation, leading to the development of several devices, beginning with the first fixed functional
appliance introduced by Herbst in 1905
