An extraorally activated expansion appliance for cleft palate infants. 1976

R A Latham, and R P Kusy, and N G Georgiade

A new lever-action expansion appliance is described which is designed specifically for use in infants with cleft lip and palate. An extraoral control knob allows for easy activation, while the important anterior cleft areas are left clear for premaxillary repositioning and clinical assessment. Activation is registered by a positive clicking sound. Rapid expansion is made possible by the design of the appliance which is retained by stainless steel pins.
