A study was performed to identify the area within the maxilla where vertical maxillary deformities are expressed. Analysis of the maxillas of individuals who displayed 4 mm or more of the central incisors at rest were compared with those who displayed less than 1 mm. Similarly, individuals who had greater than or equal to 2 mm negative incisor overbite (open-bite) were compared with those who had greater than or equal to 2 mm positive overbite. The results showed that the vertical position of the maxillary skeleton (palate) was similar in all groups. The vertical excess was found to lie within the dentoalveolus. The clinical implications of these results are discussed.
进行了一项研究，以确定上颌骨中表现出垂直上颌骨畸形的区域。将静息时中切牙显示出4毫米或更多的个体的上颌骨与显示少于1毫米的个体的上颌骨进行分析比较。同样，将切牙覆合大于或等于2毫米（开颌）的个体与覆合大于或等于2毫米的个体进行比较。结果表明，所有组中上颌骨骨架（腭）的垂直位置相似。垂直过度部分位于牙槽骨内。讨论了这些结果的临床意义。
