Abstract
The utility model discloses a kind of support implantation body.Described support implantation body comprises bionical root of the tooth 1, repairs base station 2, attachment screw 3; Described reparation base station 2 is fixedly connected on described bionical root of the tooth 1 upper end by described attachment screw 3; Described bionical root of the tooth 1 top is provided with ring-shaped groove 4; Described bionical root of the tooth 1 outer surface is provided with screw thread 6 and lower screw thread 5; Described upper screw thread 6 is trapezoidal thread or rectangular thread, and described lower screw thread 5 is angular thread; Described bionical root of the tooth 1 bottom has chip removal groove 7.The support implantation body of this structure, enhances the long-time stability of structure, and make the service time of structure longer, retention strengthens greatly, and structure is not easily fractureed, and avoids and makes adjacent teeth generation dental caries bad because of plantation, can recover the original function of tooth better.
Description
Technical field
This utility model relates to a kind of supports implantation body, particularly relates to that a kind of long-time stability are high, service time long, the bad support implantation body of dental caries not easily occurs retention for frangibility, adjacent teeth by force, not.
Background technology
Dental Implant refer to a kind ofly to support based on the in-house substructure of implantable bone, the agomphosis repair mode of maintenance top dental case.It comprises the support implantation body of bottom and the dental case two parts on top.Its adopts artificial material (as metal, pottery etc.) to make implantation body's (similar root form), underwent operative method implanting tissue interior (normally going up lower jaw) also obtains osseous tissue firmly maintenance support, is connected the dental case supporting top by special device with mode.Dental Implant can obtain the repairing effect quite similar with natural teeth function, structure and aesthetic, has become the first-selected repair mode of more and more agomphosis patient.
Utility model content
In view of the foregoing defects the prior art has, this utility model aims to provide that a kind of long-time stability are high, service time is long, the bad support implantation body of dental caries not easily occurs retention for frangibility, adjacent teeth by force, not.
To achieve these goals, this utility model by the following technical solutions: a kind of support implantation body, comprises bionical root of the tooth, repairs base station, attachment screw; Described reparation base station is fixedly connected on described bionical root of the tooth upper end by described attachment screw; Described bionical root of the tooth top is provided with ring-shaped groove; Described bionical root of the tooth outer surface is provided with screw thread and lower screw thread; Described upper screw thread is trapezoidal thread or rectangular thread, and described lower screw thread is angular thread; Described bionical root of the tooth bottom has chip removal groove.
As the improvement to the technical program, described bionical root of the tooth external diameter is between 4.4mm to 5.1mm.
As the improvement to the technical program, described ring-shaped groove quantity is 2.
As the improvement to the technical program, the quantity of described chip removal groove is 3.
As the improvement to the technical program, the height of described chip removal groove is 2.8mm-4.2mm.
As the improvement to the technical program, the degree of depth of described chip removal groove is 0.80mm-1mm.
As the improvement to the technical program, described bionical root surface have passed through acid etching.
Compared with the prior art; this utility model is owing to have employed technique scheme; enhance the long-time stability of structure; make the service time of structure longer; retention strengthens greatly; structure is not easily fractureed, avoids and make adjacent teeth generation dental caries bad because of plantation, the original function of tooth can be recovered better.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model embodiment, is the A-A sectional view of Fig. 2.
Fig. 2 is the appearance figure of this utility model embodiment.
In figure: 1 bionical root of the tooth, 2 repairs screw thread, 7 chip removal grooves on base stations, 3 attachment screws, 4 ring-shaped grooves, 5 times screw threads, 6.
Detailed description of the invention
Below by embodiment, this utility model is specifically described; what be necessary to herein means out is that following examples are only for being further detailed this utility model; 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 according to foregoing to this utility model.
Embodiment: a kind of support implantation body, as shown in Figure 1-2, supports that implantation body comprises bionical root of the tooth 1, repairs base station 2, attachment screw 3; Described reparation base station 2 is fixedly connected on described bionical root of the tooth 1 upper end by described attachment screw 3; Described bionical root of the tooth 1 top is provided with ring-shaped groove 4; Described bionical root of the tooth 1 outer surface is provided with screw thread 6 and lower screw thread 5; Described upper screw thread 6 is trapezoidal thread or rectangular thread, and described lower screw thread 5 is angular thread; Described bionical root of the tooth 1 bottom has chip removal groove 7.
The Main Function of bionical root of the tooth 1 implants alveolar bone, obtains the firm support of osseous tissue, to support the dummy that it is installed in the future.Through clinical proof, (as shown in Figure 2, being d) usually should between 4.4mm to 5.1mm for described bionical root of the tooth 1 external diameter.
The form of ring-shaped groove 4 makes the sclerotin around it can grow into and be full of groove, implantation body and osseous tissue is made to be formed to embed closely and be connected, if imitative natural root of the tooth is the same with the natural fusion between alveolar bone, which not only improves the retention of implantation body's short-term, that impels one-stage operation to plant is successfully completed, and ensures spending smoothly of synosteosis phase, and after whole successful surgery is completed, the long-time stability of Dental Implant are guaranteed, and make the service time of Dental Implant longer.Meanwhile, because the position of ring-shaped groove 4 is on bionical root of the tooth 1 top, near the position of easy fracture, the growing into of sclerotin contributes to strengthening sclerotin to the support of structure and improves the safety coefficient of structure, and Dental Implant is in use not easily ruptured.Learn through test, ring-shaped groove 4 quantity preferably 2, distance (as shown in Figure 2, being M) the preferably 0.26mm-0.30mm of ring-shaped groove 4 top and bionical root of the tooth 1 upper surface, spacing (as shown in Figure 2, being S) between ring-shaped groove 4 is 0.60mm-0.90mm preferably; The preferred 0.06mm-0.10mm of the degree of depth of ring-shaped groove 4.
The combination of upper screw thread 6 and lower screw thread 5 two kinds of different screw threads instead of traditional single thread forms.This is to play trapezoidal thread or the high characteristic of rectangular thread intensity, being arranged at bionical root of the tooth main body section to strengthen the ability of its collapse resistance; Utilize the feature that angular thread is comparatively sharp, be arranged at bionical root of the tooth end to play its self tapping effect, be convenient to Operation.
The effect of chip removal groove 7 has two, and one is can so that clean residual impurity in operation, and effectively avoid adjacent teeth thoroughly pathological changes not to occur even dental caries are bad because of clean, two is to start root bone tissue growth after planting, realizes quick maintenance.Learn through a series of experiment, the quantity of chip removal groove 7 preferably 3, height (as shown in Figure 2, being L) preferably 2.8mm-4.2mm, the preferred 0.80mm-1mm of the degree of depth of chip removal groove 7 of chip removal groove 7.
In order to obtain larger contact area, promote bone fusion, bionical root of the tooth 1 surface have passed through acid etching.
