Because accurate post fit is important to maximize both retention and support, the screw post should be used with the matched post/reamer syste; and accurate contrangle drilling should be maintained.
由于根柱和根柱孔的精密吻合，对于固位及力量传递的支持有重要的影响，因此打桩时要精确做到根柱孔的乡钻制，对于偏斜的弯机要避免使用，而且要选用同号组合配对的钻针。
Cancellous bone screw track enhanced by bone cement increases screw retention force, benefits screw compression, enhances bone-screw interface to transfer the stress to screw-bone regions, which significantly increases the anti-flexion and anti-torsion strength of dynamic hip screw and improves fracture stability.
采用骨水泥强化松质骨钉道后，骨水泥强化不仅增加螺钉把持力，有利于尾钉加压；同时也扩大了骨-钉接触界面，应力被分散传递至更大的钉-骨界面区域，明显提高动力髋螺钉固定的抗弯曲和抗扭转强度，整体提高骨折稳定性。
Retention gear pump, motor and foot screws, screw the force should be uniform, reliable connection.
紧固齿轮泵、电动机的地脚螺钉时，螺钉受力应均匀，连接可靠。
Application of the Screw Self-threading Retention Pin and Light-cure Composite Resin in the Restoratio of Injured Anterior Permanent Teeth
螺纹钉固位光固化复合树脂在外伤性恒前牙修复中的应用
But there are few systematic reports about the effects of different material combinations of the superstructure, the different screw head angles and different preloads on the retention of the screw.
但上部结构的材料组成不同是否影响螺钉固位，固位螺钉外展角以及预载荷不同等综合因素共同作用将对螺钉固位产生怎样的力学影响，尚缺乏系统性的研究报告。
