本研究的材料包括310名哥本哈根儿童的石膏模型，每个儿童在3岁时的一个月内进行印模。该闭塞与研究时儿童的吸吮习惯有关。在尖牙区和磨牙区观察矢状咬合吸吮习惯的影响。在3岁时继续吮吸假人的儿童中，远侧犬齿关系的比例高于从未吮吸过的儿童的手指吸盘。在乳第二磨牙区，各吸吮组之间无显著差异。开咬在坚持吸吮习惯的儿童中明显占主导地位。
The material for the present study comprises plaster models of 310 Copenhagen children, impressions for which were taken during the month each child attained the age of 3 years. The occlusion was related to information concerning the child's sucking habits up to the time of the study. The effect of sucking habits of sagittal occlusion was observed in the canine region and the molar region. A higher proportion of distal canine relationships was recorded in children who continued to suck dummies at the age of 3 years than among finger-suckers of children who have never sucked. In primary second molar region no significant difference was recorded between the various sucking groups. The open bite is clearly dominant among children who persist with a sucking habit.
