摘　　要：笔者通过对上海地区128例替牙期、恒牙初期正常(牙合)儿童的Wits分析测量,取得该地区正常胎儿童的Wits正常值,并发现:(1)替牙(牙合)期与恒牙初期儿童的Wits值无显著差异;(2)不同地区汉族正常胎儿童Wits值无显著差别;(3)替牙胎期、恒牙初期及恒牙期的纵向比较表明,Wits值在整个生长发育过程中变化很小;(4)Wits法能精确反映上下基骨间的矢状关系。128 children in Shanghai with normal mixed or early permanent dentition were selected in this servey to gain their normal value of the 'wits' approsal . The results showed (1) there was no significant difference of 'wits' approsal between the two groups of the children (2) There was no disparity in 'wits' approsal of the children with the same nationality and living in different regions (3) There was a'little change in value of the 'wits' approsal during the growth period of the children, which indicated a comparative identical relationship between the upper and lower basal bone. This study suggested that the application of the 'wits' approsal be very important in orthodontic clinic because of its expressing exactly the relationship of the jaws.
