Abutment portion 1 is provided with shrinkage pool 11 for fastening bolt and female thread 12 vertically in inside, female thread 12 extends to the thread cavity 231 of threaded portion 2; Described threaded portion 2 is provided with cavity 23 vertically in inside, cavity 23 upper end is thread cavity 231, the chamber wall of thread cavity 231 is provided with the screw thread identical with female thread 12, and lower end is spiral type cavity 232, and threaded portion 2 has the outer surface of female thread 12 not arrange cavernous structure 22 in inside.
Spiral type cavity 232 is cylindrical thread shape cavity, the large footpath of thread-shaped cavity 232 is greater than the large footpath of thread cavity 231, the path of spiral type cavity 232 equals the path of thread cavity 231, cylindrical cavity is provided with in the middle of thread-shaped cavity 232 spiral, the diameter of cylindrical cavity equals the inside diameter of spiral type cavity 232 spiral, thus cylindrical cavity is connected with spiraled cavity.
Preferably, the shape of described cavernous structure 22 is circular, polygon or irregularly shaped, the even or uneven distribution along spiral curve direction.
Preferably, described cavernous structure 22 is for running through the through hole of spire 2 sidewall.
Preferably, the degree of depth of described cavernous structure 22 is less than 1mm.
Preferably, the material of described implantation body is titanium alloy.
The beneficial effect that the present invention obtains is as follows:
Implantation body provided by the present invention adopts integrated design, and only have parts, by producing fast in conjunction with 3D printing technique, processing technique is simple.Meanwhile, the position that this implantation body contacts at alveolar bone is provided with cavernous structure, and the contact surface increasing alveolar bone and implantation body connects, and the inside of implantation body is provided with cavity, for the growth of alveolar bone provides space, is more conducive to the firm of implantation body and alveolar bone.

Detailed description of the invention
Below in conjunction with specific embodiment, the present invention will be further described, but the present invention is not by the restriction of embodiment.
Material therefor, instruments and methods in following embodiment, without specified otherwise, be this area conventional material, instruments and methods, all obtain by commercial channel.
In description below the present invention, it should be noted that, term " " center ", " longitudinal direction ", " transverse direction ", " on ", D score, " front ", " afterwards ", " left side ", " right side ", " top ", " end ", " interior ", orientation or the position relationship of the instruction such as " outward " and " endways " are based on orientation shown in the drawings or position relationship, only the present invention for convenience of description and simplified characterization, instead of indicate or imply that the device of indication or element must have specific orientation, with specific azimuth configuration and operation, therefore limitation of the present invention can not be interpreted as.
In description below the present invention, it should be noted that, unless otherwise expressly provided and limit, term " installation ", " being connected ", " connection " should be interpreted broadly, and such as, can be fixedly connected with, also can be removably connect, or connect integratedly; Can be direct connection, can also be indirectly connected by intermediary, can be the connection of two components interior.For the ordinary skill in the art, concrete condition above-mentioned term concrete meaning in the present invention can be understood.
