面部垂直高度发育过量的儿童或成人具有特殊的面形,称为“长面综合症”。因为这些人常常同时伴有开(牙合),故又称其为垂直高度发育过度的“骨性开(牙合)”。然而并非所有的长面形人都有开(牙合),而开(牙合)病人也并非都是长面形。本文研究的目的是:(1)对临床分类为长面形、正常面形和短面形的儿童和成人进行骨骼和牙的形态研究。(2)确定临床长面形的有关形态学因素。材料和方法 6～12岁白人儿童42名,白人青年42例,均由两位正畸专家经两次检查确定为长面形、正常面形和短面形。儿童组长面形13人,
Children or adults with excessively high facial vertical height have a special face shape called “face syndrome.” Because these people often accompanied by open (occlusion), it is also known as the vertical height overdone “bony open occlusion.” However, not all long faces have open occlusions, and not all occluded patients are long faces. The purpose of this study is: (1) to study the morphology of bones and teeth in children and adults with clinical classification of long, normal and short sides. (2) to determine the morphological factors of clinical long form. Materials and Methods 42 white children aged 6 to 12 and 42 white young people were diagnosed as long, normal and short by two orthodontic experts. Children's head of 13 people,
