With the help of the computerized cephalometric system the author made an analysis of the single and multiple factors of 93 individuals in early permanent dentition. These dentition were divided into two groups-deep overjet of the front teeth and normal occlusion. The results showed that deep overjet of the front teeth in early permanent dentition is a syndrome including the abnormality of the teeth position, the size and position of the jaw bones and even the cranial base It is believed that the coordination effect of each abnormal structure on the formation of deep overjet syndrome should be identified as a whole.
借助计算机化头影测量系统，作者对93例恒牙早期个体的单因素和多因素进行了分析。这些牙列被分为两组——前牙深覆盖和正常咬合。结果表明，恒牙早期前牙深覆盖是一种综合征，包括牙齿位置异常、颌骨大小和位置甚至颅底异常。认为应将各异常结构对深覆盖综合征形成的协同作用作为一个整体来认识。
