In our experment through the methods of histochemistry and the techniques of incorporation of tetracyline, we emphatically explored the changes and mechanism that alveolar bone respond to mechanical force,especially study the changes of alveolar bone adjacent to the hyalinizecl area.The rcsnlts suggest; orthodontic forces inhabited alkaline phosphatase activity and tetracyline complex on the bone surfaces in the pressure zones of the periodontal member depending on magnitude of the force,the change was associated with inhibited bone formation and subsequent initiation of bone resorption.The intense alkaline phosphatase activity and tetracycline was found on the tension sids with low force.There was no change in group of high forces.It suggested that bone formation was associated with the value of force.

本实验使用固定矫治器对90只Wistar鼠分别施以50、100克矫治力后观察不同时期内(1、3、6天)牙槽骨表面碱性磷酸酶及四环素混合物的变化。结果表明:正畸力抑制压力侧牙槽骨表面的碱性磷酸酶活性及四环素混合物的形成,这种抑制作用与力值的大小有关。此变化是由于骨形成受到抑制以及随后的骨吸收引起的。张力侧碱性磷酸酶活性及四环素混合物的形成也与力值的大小有关,说明骨形成也受力值的影响。
