The Norwegian Appliance—A Review
Abstract: Functional appliances are passive appliance fabricated to alter the neuromuscular environment of the orofacial region to enhance craniofacial skeletal growth and occlusal development. The monobloc, given by Pierre Robin in 1902, is considered the forerunner of the functional appliance, but the appliance fabricated by Andresen in Norway was the first functional appliance to be widely accepted. This appliance was considered the basis of the ‘Norwegian system’ of treatment. The Norwegian …
