Abstract
The utility model discloses a combined grindable pile dental implant. The combined grindable pile dental implant comprises a pile 1, a neck part 2, a porous tantalum structure 7 and a root part 3 from the top to the bottom, wherein the pile 1 and the neck part are combined into a whole; the pile 1 is separated into an upper pile 4 and a lower pile 5; the upper pile 4 is of a solid cylinder structure, while the lower pile 5 is a big end up solid conical structure; the middle part of the circumference of the neck part 2 is reduced, and the vertical section is of an arc shape; the root part 3 is connected with the hollow cylindrical porous tantalum structure 7 through a box 8 on the upper part of the root part; the part of the small cylinder of the boss 8 over the height of the porous tantalum structure 7 is provided with a screwed thread; and the root part 3 is connected with a screw hole on the neck part 2 through the screwed thread. The dental implant with the structure has a grindable pile, and is strong in implanting adaptability, so that the repairing appearance is improved, forcible bending is avoided, and biocompatibility and long-term stability of the structure are improved.
Description
Technical field
The utility model is related to a kind of tooth implant, more particularly to a kind of grinds that foundation pile, strong adaptability, aesthetics are high, avoid bending, the tooth implant of good biocompatibility.
Background technology
At present, artificial growth tooth system is broadly divided into two major classes：One class is single-piece tooth implant, and its implant abutment and root is integral；Another kind of is combined type tooth implant, and its implant abutment and root are separated.
Due to the influence of jawbone anatomical structure, the direction of tooth implant implantation sometimes is unfavorable for upper crown reparation, it is necessary to which foundation pile forms gyration to be corrected with root.Combined type tooth implant is corrected by connecting gyration foundation pile, but junction easily loosens.And existing single-piece tooth implant, foundation pile and root direction are consistent, and in order to allow corona can wear into, foundation pile week footpath must shrink to form polymerization taper upward, therefore the direction of foundation pile is difficult to correct again.
Meanwhile, it is made more than existing tooth implant of ceramics or compact metal material, it is impossible to fully merged with sclerotin, easily occur loosening or come off, increases postoperative discomfort, influence its long-term stability.
Utility model content
In view of the foregoing defects the prior art has, the utility model, which is aimed to provide, a kind of grinds that foundation pile, strong adaptability, aesthetics are high, avoid bending, the tooth implant of good biocompatibility.
To achieve these goals, the utility model uses following technical scheme：Combined type can grind foundation pile tooth implant and be divided into foundation pile, neck, porous tantalum structure and root from top to bottom；The foundation pile and neck are integral, and the foundation pile is divided into foundation pile top and foundation pile bottom；The foundation pile top is solid cylinder structure, and the foundation pile bottom is up big and down small solid cone structure；Reduced in the middle part of the neck Zhou Jing, vertical section is in circular arc；Boss of the root by its top is connected with the porous tantalum structure in hollow circular cylinder shape；The boss small cylinder is provided with screw thread beyond the part of the porous tantalum structure height, and the root is connected by the screw thread with the screw on the neck.
As the improvement to the technical program, the root main body is up big and down small conical structure.
As the improvement to the technical program, the foundation pile top is provided with flat horizontal surface tool interface.
As the improvement to the technical program, foundation pile bottom taper is 6 ° -8 °.
Compared with the prior art, the utility model plants strong adaptability, improves the aesthetics of reparation by adopting the above-described technical solution, foundation pile can be ground, it is to avoid bending by force, improves the biocompatibility and long-term stability of structure.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model embodiment.
In figure：1 foundation pile, 2 necks, 3 roots, 4 foundation pile tops, 5 foundation pile bottoms, 6 flat horizontal surface tool interfaces, 7 porous tantalum structures, 8 boss.
Embodiment
The utility model is specifically described below by embodiment; be necessary it is pointed out here that be that following examples are served only for that the utility model is further detailed; it is not intended that the limitation to the utility model protection domain, those skilled in the art can make some nonessential modifications and adaptations according to the above to the utility model.
Embodiment：A kind of combined type can grind foundation pile tooth implant, as shown in figure 1, combined type can grind foundation pile tooth implant is divided into foundation pile 1, neck 2, porous tantalum structure 7 and root 3 from top to bottom；The foundation pile 1 and neck 2 are integral, and 1 point of the foundation pile is foundation pile top 4 and foundation pile bottom 5；The foundation pile top 4 is solid cylinder structure, and the foundation pile bottom 5 is up big and down small solid cone structure；The neck reduces in the middle part of 2 weeks footpaths, and vertical section is in circular arc；Boss 8 of the root 3 by its top is connected with the porous tantalum structure 7 in hollow circular cylinder shape；The small cylinder of boss 8 is provided with screw thread beyond the part of the height of porous tantalum structure 7, and the root 3 is connected by the screw thread with the screw on the neck 2.
In order to fully adapt to the architectural feature of alveolar bone, the main body of root 3 is up big and down small conical structure.
For the convenience that enforcement surgery is operated, the foundation pile top 4 is provided with flat horizontal surface tool interface 6.
In order to fully coordinate with human body alveolar bone, preferably 6 ° -8 ° of the taper of foundation pile bottom 5.
Because foundation pile bottom has up big and down small reverse taper so that all footpaths in foundation pile top are larger, and leeway is ground with larger.After tooth implant implantation, foundation pile top can be ground as needed in oral cavity by doctor, the upward polymeric species into corona can be worn by re-forming, while changing foundation pile angle, enhance the aesthetic property of reparation.Simultaneously as with the characteristic that can be ground, so as to avoid bending by force.Porous tantalum structure can strengthen the biocompatibility of tooth implant, and promotion tooth implant is merged with human body bone, improves the long-term stability of plantation.
