Abstract
The utility model discloses a unit dental implant. The unit dental implant comprises a pile 1, a neck part 2 and a root part 3 from the top to the bottom, wherein the pile 1 is divided into an upper pile 4 and a lower pile 5, the upper pile 4 is of a solid cylinder structure, and the lower pile 5 is of a big end up solid conical structure; the circumference middle part of the neck part 2 is reduced, and the vertical section is of an arc shape; the root part 3 is of a big end up conical structure; a central vertical passage 7 and four horizontal passages 8 are arranged in the tail end of the lower part of the root part 3, the central vertical passage 7 is connected and communicated with one end of each horizontal passage 8 respectively, and the other end of each horizontal passage 8 is uniformly distributed on the periphery of the root part 3; and a porous tantalum material is filled in the central vertical passage 7 and the horizontal passages 8. According to the dental implant with the structure, the pile state can be adjusted, the repairing difficulty can be reduced, enforced bending is avoided, the biocompatibility is improved, and bone tissue growth can be started.
Description
Technical field
This utility model relates to a kind of tooth implant, the tooth implant that relate in particular to and a kind ofly grind foundation pile, avoid bending, biocompatibility is high, can starts bone growth.
Background technology
At present, the artificial growth tooth system mainly is divided into two large classes: a class is the epimere foundation pile and the parts of hypomere root for separating of implantation body, is called the combination type tooth implant; Another kind of implant abutment and root are an integral body, are called the single-body type tooth implant.Because the impact of jawbone anatomical structure, the direction of sometimes tooth implant implantation is unfavorable for top corona reparation, needs foundation pile and root to form gyration and corrects.The combination type tooth implant is to correct by connecting the gyration foundation pile, but the junction is loosening easily.And existing single-body type tooth implant, foundation pile is consistent with the root direction, and for allow corona can wear into, foundation pile week the footpath must shrink upward and form the polymerization tapering, therefore the direction of foundation pile is difficult to correct again.
Simultaneously, existing tooth implant adopts pottery or compact metal material to make more, and biocompatibility is not high, can not fully merge with sclerotin, is unfavorable for starting bone tissue growth.
The utility model content
In view of the foregoing defects the prior art has, the tooth implant that this utility model aims to provide and a kind ofly grinds foundation pile, avoids bending, biocompatibility is high, can start bone growth.
To achieve these goals, this utility model by the following technical solutions: the single-body type tooth implant is divided into foundation pile, cervical region and root from top to bottom; Described foundation pile is divided into foundation pile top and foundation pile bottom; Described foundation pile top is the solid cylinder body structure, and described foundation pile bottom is up big and down small filled circles cone structure; Described cervical region Zhou Jing middle part dwindles, and longitudinal section is circular arc; Described root is up big and down small conical structure; Establish central vertical passage and four horizontal channels in the described root lower end, described central vertical passage is connected conducting with described horizontal channel one end respectively, and the other end of described horizontal channel is evenly distributed on around the described root; All be filled with the porous tantalum material in described central vertical passage and the described horizontal channel.
As the improvement to the technical program, described foundation pile top is provided with the flat horizontal surface tool interface.
As the improvement to the technical program, described root tapering is 10 °.
As the improvement to the technical program, described root outer surface belt screw thread.
Compared with the prior art, this utility model makes foundation pile form scalable owing to adopted technique scheme, has reduced the reparation difficulty, has avoided by force bending, has improved the biocompatibility of structure, is conducive to start bone growth.
Description of drawings
Fig. 1 is the structural representation of this utility model embodiment.
Fig. 2 is p-p direction cutaway view.
Among the figure: 1 foundation pile, 2 cervical regions, 3 roots, 4 foundation pile tops, 5 foundation pile bottoms, 6 flat horizontal surface tool interfaces, 7 central vertical passages, 8 horizontal channels.
The specific embodiment
Below by embodiment this utility model is carried out concrete description; be necessary to be pointed out that at this following examples only are used for this utility model is further detailed; can not be interpreted as the restriction to this utility model protection domain, those skilled in the art can make some nonessential improvement and adjustment to this utility model according to foregoing.
Embodiment: a kind of single-body type tooth implant, as depicted in figs. 1 and 2, the single-body type tooth implant is divided into foundation pile 1, cervical region 2 and root 3 from top to bottom; Described foundation pile 1 is divided into foundation pile top 4 and foundation pile bottom 5; Described foundation pile top 4 is the solid cylinder body structure, and described foundation pile bottom 5 is up big and down small filled circles cone structure; Middle part, described cervical region 2 week footpath dwindles, and longitudinal section is circular arc; Described root 3 is up big and down small conical structure; Establish central vertical passage 7 and four horizontal channels 8 in described root 3 lower end, described central vertical passage 7 is connected conducting with described horizontal channel 8 one ends respectively, and the other end of described horizontal channel 8 is evenly distributed on around the described root 3; Described central vertical passage 7 and the described horizontal channel 8 interior porous tantalum materials that all are filled with.
For the ease of operation technique, described foundation pile top 4 is provided with flat horizontal surface tool interface 6.
In order fully to cooperate with the human body dental bed, described root 3 taperings are preferred
10°。
For the ease of implant procedure, described root 3 outer surface belt screw threads.
Relative foundation pile bottom, Zhou Jing is larger on foundation pile top, has larger ground leeway.Tooth implant can grind foundation pile top as required by the doctor after implanting in the oral cavity.Simultaneously, owing to have the property of grinding, therefore avoided contingent by force bending.Porous tantalum in root lower end central vertical passage and the horizontal channel can strengthen the biocompatibility of structure, starts the growth of body bone tissue, promotes to repair fast.
