The Pendulum appliance is an orthodontic device attached to the premolars and placed in bands on the molars, utilizing bent TMA springs with a helix to generate a distalizing force on the teeth. Pendex is an extended version, which, in addition to the distalization function, includes a screw that allows for the expansion of the upper dental arch.
