龋齿是人类常见病之一。据临床观察第一恒磨牙龋坏较多,特别是下颌第一恒磨牙,患龋率更高。我们自1981年以来,采用适时拔牙法。目的是使自身的牙齿正常生理萌出,占据缺失牙位的方法。这种方法的原理类似正畸。但所不同点是利用牙齿萌出的潜力,也就是牙齿的生理的拾向及近中移动,代替正畸矫治器的动力。

Dental caries is one of the common human diseases. According to the clinical observation of the first permanent molars more caries, especially the first permanent molars mandible, dental caries rate is higher. We have adopted a timely extraction method since 1981. The purpose is to make its own normal physiological eruption of teeth, the method of occupying the missing teeth. The principle of this method is similar to orthodontics. But the difference is the use of the potential of tooth eruption, which is the physical orientation of the teeth and move in the near, instead of orthodontic appliance power.
