Thirty-five cadavers were studied to determine the depth of penetration of the needle from the oral mucous membrane to the inferior alveolar nerve at the mandibular foramen. The depth of penetration at the narrowest anteroposterior width of the ramus and pterygotemporal depression was determined to be half the narrowest anteroposterior width of the ramus plus or minus 1 mm. This depth was within the limits of a short needle. It was easier to estimate the depth of penetration with a short needle than with a long needle. A short needle also was less likely to go too deep and deviate from its course than was a long needle.
对35具尸体进行研究，以确定从口腔黏膜至下颌孔处下牙槽神经的进针深度。在升支最窄的前后径宽度处及翼颞凹陷处的进针深度被确定为升支最窄前后径宽度的一半加减1毫米。此深度在短针的范围内。与长针相比，使用短针更容易估计进针深度。短针也比长针更不容易进针过深并偏离其路径。
