Abstract
The utility model discloses a kind of artificial tooth implanting body, belong to technical field of medical instruments.Implantation body provided by the utility model comprises head, middle part and bottom.Wherein, middle part is cylindrical, and outer wall is provided with circular opening, and circular opening is uniformly distributed 11 circles along the axis at middle part, meanwhile, the outer wall at middle part is provided with screw thread, so that be connected with alveolar bone.Implantation body provided by the utility model adopts integrated design, and only have parts, by producing fast in conjunction with 3D printing technique, processing technique is simple.The position that implantation body provided by the utility model contacts at alveolar bone is provided with cavernous structure, and the contact surface increasing alveolar bone and implantation body connects, and for the growth of alveolar bone provides space, is more conducive to the firm of implantation body and alveolar bone.
Description
Technical field
This utility model relates to a kind of artificial tooth implanting body, belongs to technical field of medical instruments.
Background technology
Artificial tooth is commonly called as artificial tooth, is the general name to the latter made dummy of the part or all of absence of tooth of the upper jaw and the lower jaw tooth.But directly artificial tooth is embedded on alveolar bone and easily occurs problem firm not.Occurred that one was called the technology of " Dental Implant " in recent years, and be exactly Implant in advance in alveolar bone, formed after stable synosteosis until implantation body and alveolar bone, then inlay artificial tooth in implantation body, the firm of artificial tooth can be guaranteed like this.
But the implantation body in currently available technology exists, and parts are more, and structure is too complicated, process loaded down with trivial details problem, greatly constrain the use of implantation body.
Utility model content
For solving the problem, it is simple that this practical information provides a kind of structure, easy to process, the artificial tooth implanting body that simultaneously firmly can be combined with alveolar bone, and the technical scheme taked is as follows:
The purpose of this utility model is to provide a kind of artificial tooth implanting body, comprises head 1, middle part 2 and bottom 3.Wherein, middle part 2 is cylindrical, and outer wall is provided with circular opening 21, circular opening 21 is uniformly distributed 11 circles along the axis at middle part 2, meanwhile, the outer wall at middle part 2 is provided with screw thread 22, so that be connected with alveolar bone, the pitch of screw thread 22 is less than or equal to 1/7th of middle part 2 length.
Preferably, the pitch of described screw thread 22 is greater than the diameter of circular opening 21.
Preferably, described circular opening 21, the sectional uniform distribution of circular opening 21 2 radial circumferences in the middle part of place of each circle.
Preferably, the width of described screw thread 22 threaded line is less than the diameter of circular opening 21, make when screw thread 22 around during 2 outer wall of middle part can not by the circular opening 21 of process block completely.
Preferably, the degree of depth of described circular opening 21 is not less than 1mm, so that leave enough spaces to the growth of alveolar bone.
Preferably, described head 1 is provided with annular protrusion or the shoulder structure that diameter is greater than middle part 2 outer diameters.
Preferably, described bottom 3 is provided with round platform or the dome structure that diameter is less than middle part 2 outer diameters.
The beneficial effect that this utility model obtains is as follows:
Implantation body provided by the utility model 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 for the growth of alveolar bone provides space, is more conducive to the firm of implantation body and alveolar bone.
Accompanying drawing explanation
Fig. 1 is a kind of perspective view of this utility model implantation body.
In figure: 1, head; 2, middle part; 3, bottom; 11, upper end round platform; 12, lower end round platform; 21, circular opening; 22, screw thread; 31, round platform; 32, dome.
Detailed description of the invention
Below in conjunction with specific embodiment, this utility model is described further, but this utility model 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.
Below in conjunction with accompanying drawing, this utility model is elaborated.Fig. 1 is the perspective view of implantation body in a kind of preferred version of this utility model.As can be seen from Figure 1, this implantation body comprises head 1, the integral structure of middle part 2 and bottom 3.Head 1 comprises upper end round platform 11 and lower end round platform 12, and both junctions form a shoulder structure, so that implantation body contacts with alveolar bone.Female thread is provided with, for connecting or fixed denture in the center of head 1.
Middle part 2 is cylindrical, and one end is connected with the lower end round platform 12 of head 1, and the other end is connected with bottom 3.The cylindrical outer wall at middle part 2 is axially evenly provided with the circular opening 21 of 11 circles, and circular opening 21 of each circle even circumferential distribution in radial interface along place along it, to ensure that implantation body is identical in all directions with the contact area of alveolar bone.The degree of depth of circular opening 21 is greater than 1mm, to ensure that alveolar bone has enough Growth In Spaces.The outer wall of the column structure at middle part 2 is provided with 7 circle screw threads 22, the pitch of screw thread 22 is greater than the diameter of circular opening 21, simultaneously the width of the threaded line of screw thread 22 is less than the diameter of circular opening 21, with ensure screw thread 2 through circular opening 21 time circular opening 21 can not be shut completely.
Bottom 3 comprises round platform 31 and dome 32 two parts, and the major diameter bottom surface of round platform 31 is connected with middle part 2, and minor diameter bottom surface is connected with dome 32, and side is to the cambered outwards curved surface of its axle.The bottom surface of dome 32 is connected with the minor diameter disc of round platform 31, and top is the bottom surface of whole implantation body.
In manufacturing process of the present utility model, 3D printer entirety can be utilized to print implantation body, passing through or do not needed by digital control processing process the position of processing once, finally can obtain implantation body after effects on surface processes.
Although this utility model with preferred embodiment openly as above; but it is also not used to limit this utility model; any person skilled in the art; not departing from spirit and scope of the present utility model; can do various change and modification, what therefore protection domain of the present utility model should define with claims is as the criterion.
