Lateral cephalometric radiographs were obtained for ten patients treated with Jasper Jumper appliances from three locations. Pre and post-appliance measurements were compared to determine the cephalometric effects seen in this group of patients. All patients in this study exhibited mesofacial to brachyfacial growth patterns and were all of growing age. All patients were treated to Class I along the complete buccal segment. The results yielded the following conclusions: 1) the facial axis did not open and the lower face height did not increase significantly for this group of patients, 2) there is an intrusive effect delivered to the upper first molars, 3) superimpositions revealed efficient orthodontic movement of the upper first molar with some advancement and minor flaring of the lower incisor, 4) possible orthopedic and functional effects were demonstrated by tipping of the palatal plane and an increase in the facial depth beyond normal growth increases.
