Description
Technical field
This utility model relates to a kind of Maxillary Sinus base station.
Background technology
When maxillary molar region carries out implant operation, usually because the reason of maxillary sinus causes bone height at the bottom of hole not enough, need to carry out
Maxillary Sinus.Current Maxillary Sinus is the operation that a success rate is very high, and successfully one of key keeps implant to stablize.(Dou Tisheng base station keeps its implant (i.e. threaded post) to stablize to a kind of base station of U.S. BICON implant system specialized designs as shown in Figure 1).
This is a very creative and fruitful design, and in the success rate that clinical acquisition is high, we in use find that there is the place can improving raising.
BICON genuine hole promotes base station following deficiency:
1, when bone height at the bottom of hole is lower than 3 millimeters, implant (i.e. base station 1) cannot contact with surrounding bone tissue tight, can not obtain enough primary stabilities;
During the lower quadrate bone plane non-horizontal of 2, some case, easily cause implant major axis (i.e. threaded post 2) crooked;
3, genuine hole promote base station be difficult to complete not to the marrow in, base station can be caused to give prominence to bone plane more, gingiva not easily draws stitching over to one's side, easily causes wound to split;
4, Maxillary Sinus needs secondary operation to be taken out by base station after performing the operation 4 months, and genuine design base station center is circular design (i.e. circular deep gouge 11), does not have corresponding kit, causes second phase more difficult dismounting Dou Tisheng base station.
Utility model content
This utility model makes improvement for above-mentioned prior art Problems existing, and namely technical problem to be solved in the utility model is to provide a kind of Maxillary Sinus base station, can with osseous tissue close contact, good stability, adaptability is good, is convenient to installing/dismounting.
In order to solve the problems of the technologies described above, the technical solution of the utility model is: a kind of Maxillary Sinus base station, comprise base station body, fixed leg is provided with in the middle part of described base station body lower surface, described fixed leg is arranged with threaded post, described base station body lower surface is also provided with the annular wall around threaded post, described base station body sidewall is the circular arc of evagination, and its cross section is up-narrow and down-wide shape, described base station upper surface middle part is provided with triangle screw socket.
Further, described annular wall does not contact with threaded post.
This device fixes implant (threaded post) for coordinating during the operation of Bicon implantation body Maxillary Sinus, especially for phatnoma bone height less adopt the Dou Tisheng base station of routine cannot obtain enough stable time,
Annular wall has certain height, has different diameters, has certain gap between annular wall and threaded post;
Circular arc pedestal sidewall in evagination, be similar to sphere, thickness is less, can reduce mucosa tension force, reduces the risk that wound splits, suture (10) comes off;
Triangle screw socket has certain depth and height.
Annular wall has certain height, is convenient to fully contact with alveolar bone and obtain retention, helps Bicon implantation body to obtain primary stability.Annular wall has different diameters, makes it the implant being applicable to different-diameter, and the diameter of annular wall is slightly wide compared with the implant nest hole dia that alveolar bone prepares, and base station can be clamped on alveolar bone as enough stability improves in implantation body.Certain gap is had to make the in place not by the impact of annular wall of implantation body between annular wall and implant.
Be positioned at base station upper surface triangle screw socket and have certain height and the degree of depth, have the triangular screwdriver of coupling triangle height, the screw socket of certain depth is convenient to screwdriver and is clamped on base station, is convenient to base station and carries and dismantle.
Implant be fixed on Sinus floor alveolar bone, this base station is clamped by annular wall and alveolar bone, and after the circular arc base station face in evagination makes the little stitching of mucosa tension force, wound not easily splits, and base station upper surface has triangle screw socket to be convenient to base station dismounting.
Compared with prior art, this utility model has following beneficial effect:
1, design an annular wall in base station bottom, utilize bone wall at the bottom of residual hole to obtain maintenance, at the bottom of hole, implant during bone height wretched insufficiency, still can be kept to stablize;
2, due to the packing interaction of annular wall and residual bone wall, implantation body's major axis (threaded post) is guided to carry out drill bit direction, even if implant can be kept stable when non-level lower quadrate bone plane and major axis is not easy crooked;
3, be plane bottom genuine base station, be revised as circular arc and revise height, making base station be adjacent to bone plane, reduce gingiva tension force and be convenient to draw stitching over to one's side, wound not easily splits;
4, the circular depressed on base station top makes triangle screw socket into, can use the triangular screwdriver of commercially available coupling, rotates and takes out base station.
Below in conjunction with the drawings and specific embodiments, the utility model is described in more detail.
Accompanying drawing explanation
Fig. 1 is the organigram of original structure.
Fig. 2 is the organigram of this utility model embodiment.
Fig. 3 is the organigram of base station upper surface in this utility model embodiment.
In figure: the original base station of 1-, the circular deep gouge of 11-, 12-fixed leg, 2-threaded post, the base station body that 3-is new, 31-triangle screw socket, 4-annular wall.
Detailed description of the invention
Embodiment one: as shown in Fig. 2 ~ 3, a kind of Maxillary Sinus base station, comprise base station body 3, fixed leg 12 is provided with in the middle part of described base station body 3 lower surface, described fixed leg 12 is arranged with threaded post 2, described base station body 3 lower surface is also provided with the annular wall 4 around threaded post, described base station body 3 sidewall is the circular arc of evagination, and its cross section is up-narrow and down-wide shape, described base station upper surface middle part is provided with triangle screw socket 31.
In the present embodiment, described annular wall 4 does not contact with threaded post 2.
The foregoing is only preferred embodiment of the present utility model, all equalizations done according to this utility model claim change and modify, and all should belong to covering scope of the present utility model.
