The teleradiographs and study casts of 68 patients with Down's disease were compared with those of 102 students. Pseudoprognathism, cross-bite and open bite were strikingly more frequent in the patients with Down's disease than in the students. The success of orthodontic treatment is very uncertain in patients with Down's disease. Mandibular prognathism needs in most cases surgical treatment. An open bite will be improved only if the position of the tongue is changed. Improvement of a cross-bite may be achieved by early expansion of the maxillae. In certain cases, normalization is accomplished. It is possible to reach considerable inprovements in patients showing a few or no occlusal surfaces though normal conditions cannot be established.
对68名唐氏综合征患者的远距射线照片和研究模型与102名学生的进行了比较。唐氏综合征患者的假性下颌前突、反咬合和开咬合明显比学生更常见。唐氏综合征患者正畸治疗的成功率非常不确定。下颌前突在大多数情况下需要手术治疗。只有改变舌头的位置，开咬合才能得到改善。通过早期上颌扩弓可以改善反咬合。在某些情况下，可以实现正常化。对于那些仅有少数或没有咬合面的患者，虽然无法建立正常情况，但有可能取得相当大的改善。
