| 摘 要： | 目的 建立偏侧咀嚼对正畸牙移动影响研究中的动物模型,为其后的系列研究打下基础.方法 拔除实验组大鼠右下颌所有磨牙,使右上颌第一磨牙丧失咬合接触.同时,在大鼠双侧上颌切牙和第一磨牙间放置5mm镍钛拉簧,初始力值为50g,近中移动磨牙,于0、3、7、10、14d测量大鼠上颌第一磨牙近中移动的距离.于第14天处死大鼠,通过H...

| Abstract: | Objective To establish an animal model for research on influence of unilateral mastication to the movement of the orthodontic tooth and lay foundation for the series research on this subject.Methods Animal models were induced by extracting the right mandibular molars;then the left maxillary molars served as increased bite force models while the right maxillary molars served as decreased.The untreated(non-extracting) teeth were used as the control.An initial force of 50 g drawn the maxillary first molar mesi... |
