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.
本文描述了一种新型杠杆式扩弓矫治器，专为唇腭裂婴儿设计。口外控制旋钮便于操作，同时重要的前部裂隙区域保持清晰，以便进行上颌前部复位和临床评估。通过发出清晰的咔嗒声来记录激活情况。该矫治器由不锈钢销固定，其设计使得快速扩弓成为可能。
