不同螺紋的形狀產生的剪切力的量隨著螺紋端面角度的增加而增加，而V型螺紋和反支撐螺紋中的剪切力會比方螺紋上的剪切力大10倍。螺紋骨界面處的剪切載荷的減少提供了更多的壓縮載荷傳遞，較短的植入物長度或較高的受力幅度是特別重要。

? Amount of shear force generated shape different thread threaded ends increases as the angle increases, the shearing force 10 times the shear forces for example screw threads and the V-thread of the counter-support. Reducing shear load at the interface of the bone screw provides additional compressive load transfer, the shorter length of the implant by the magnitude of force or higher are particularly important.

結果 (英文) 2:

The amount of shear force generated by the shapes of different threads increases with the angle of the end face of the thread, while the shear force in the V-thread and anti-support threads is 10 times greater than the shear force on the square thread. The reduction of shear load at the threaded bone interface provides more compression load transfer, and shorter implant lengths or higher force amplitudes are particularly important.

結果 (英文) 3:

The amount of shear force produced by different thread shapes increases with the increase of thread end angle, while the shear force in V-thread and reverse support thread is 10 times larger than that on thread. The reduction of the shear load at the interface of the threaded bone provides more compression load transfer, especially the shorter implant length or higher stress amplitude.
