Popis: The design, construction and clinical management of the quadhelix appliance are discussed. Clinically, the appliance has a useful role to play in malocclusions where moderate expansion of the upper arch is required; the appliance may be modified to act as a space maintainer or to provide additional minor tooth movements.
