口呼吸,长久以来被认为是错(牙合)病因中的一个重要因素,不过尚缺乏明确而统一的口呼吸定义。其关键在于,对口呼吸的判定仅从医生的主观认识和依据形态学而作出,缺乏各种呼吸生理和空气动力学的资料。作者研究的目的在于评价面部形态与鼻部空气流量的关系。28名15到43岁的成人作为研究对象,分为三组。①唇功能不良组:在息止位时,上下唇不能闭合,但面部的垂直发育在正常范围内,共有9名。②面部垂直高度过长组:面下高度超过面总高度的55%,共有9名。③正常组:唇功能、面部高度及突度均在正常
Breathing, which has long been considered an important cause of wrong occlusion, lacks clear and uniform definition of oral breath. The crux of the matter is that the judgment of mouth breathing is made only from the subjective understanding of the doctor and from the morphology. The lack of various respiratory physiology and aerodynamic data. The purpose of the authors' study was to evaluate the relationship between facial morphology and nasal air flow. Twenty-eight adults aged from 15 to 43 were divided into three groups. ① lip dysfunction group: in the interest stop, the upper and lower lip can not be closed, but the vertical development of the face within the normal range, a total of nine. ② facial vertical height is too long group: surface height exceeds the total surface height of 55%, a total of nine. ③ normal group: lip function, facial height and disruption are normal
