通过对正常磨牙接触进行光分析,按功能亚单位判读接触强度,发现下磨牙以颊舌发育沟分界的面远中半区的合力约为近中半区合力的1.62倍,并据此计算出下第一磨牙的前移力约为近中半区合力的1/4。
Through the analysis of the normal molars contact light analysis, according to the functional subunits interpretation contact intensity and found that the lower molars to the buccal mucocut development of the demarcation of the mid-face area is about 1.62 times the combined force in the near-mid-range and According to this calculation, the force of the first molars is about 1/4 of the resultant force in the near middle half.
