本研究对一侧后牙缺失后小型猪髁状突和关节盘碱性磷酸酶活性变化进行了观察，结果发现，一侧后牙缺失１个月后，失牙侧髁状突碱性磷酸酶活性升高，至３个月时仍呈上升趋势；非拔牙侧髁状突和两侧关节盘的碱性磷酸酶活性在失牙后１个月时升高，而至３个月时则趋于回归。这表明两侧髁状突和关节盘的骨和软骨细胞在一侧后牙缺失后代谢活性均有变化但趋势不同。
In this study, we observed the change of alkaline phosphatase activity in the condyles of the small pigs and the articular cartilage after the loss of one side of the posterior teeth, and found that one month after the loss of one side of the posterior teeth, Activity increased until 3 months still showed an upward trend; non-extraction side of the condyle and both sides of the articular disk alkaline phosphatase activity increased at 1 month after tooth loss, and to 3 months when the trend In return. This shows that the bone and cartilage of both condyles and disc are metabolically active and have a different tendency after one-sided loss of posterior teeth.
