1·Moreover, the impaction anchors never failed to expand in any material in any of the tests.
此外，在所有试验中，嵌塞锚钉的展开在任何材料中均没有失败。
2·Methods:To analyse 52 samples of food impaction retrospectively.

3·Food impaction is the phenomenon appearing in the chewing course when the food dregs or fibers are pushed into the clearance by occlusal force or owning to the gingival shrinkage.
在咀嚼过程中，由于咬合压力的作用或牙龈退缩导致食物碎块或纤维楔入相邻牙的牙间隙内的现象，称为食物嵌塞。
4·Many of these compounds can actually be collected more efficiently by means of inertial impaction or mechanical impingement than by the continuous recirculation of scrubber water.
与使用不断循环的涤器气用水相比，惯性嵌塞或机械冲击的手段能够更高效的收集化合物。
5·Methods 47 patients who suffered mixed food impaction of posterior area were randomly divided into observation group, control group.

1·If the wisdom tooth has erupted out of the jawbone but not through the gumline, it is called a soft tissue impaction.
如果智齿已经从腭骨萌出，但还没有从牙龈中长出，就称之为软组织阻生。
2·Correlations of their relationship and type of tooth impaction, gender, visibility of the white line of bone of the MC by panoramic radiography were analyzed.
分析两者之间位置关系与阻生类型、性别、曲面断层片上下颌神经管骨白线是否可见的相关性。
