The tip 1 is formed by a thin plate of Ti material of about 0.5 mm.
The arc radius of a and 11a is about 5 mm, the two arcs 1a and 1a
The center position interval of 1a is about 7 mm, the length of the blade in the depth direction is about 3 to 6 mm, the lateral width is about 10 to 30 mm, and the interval between two blades is about 2 to 3 mm. The head 2 fixed to this is processed into a cylindrical shape, a conical cylindrical shape, a prismatic shape, a pyramidal prismatic shape or a short prismatic shape having a diameter of about 2 mm, and the implant assembled by welding has about 35 to 35 mm in the head. 70 kg
When a pressure of about f is applied, the blades 1 and 11 can disperse the stress and hold it as a buffer. That is,
A concave portion is formed in the blades 1 and 11 by intersecting two circular arcs 1a, and whether the head 2 is single or double, it is 35 to 70k when engaging with this.
When a pressure of about gf is applied, it can be elastically crushed to receive the pressure, and the stress can be dispersed over the entire blade without concentration of the pressure. This buffering effect softens shocks and vibrations, and causes discomfort. It is possible to obtain a stable holding property without causing.
