Abstract
The utility model discloses a kind of combined type tooth implant.The combined type tooth implant is made up of body 7 and porous tantalum outer layer 4；The body 7 is cylindrical structural；The posterior center of body 7 is provided with round platform hole 1, and the lower section of round platform hole 1 is connected with regular hexagon hole 2, and the lower section of regular hexagon hole 2 is connected with screw 3；The side surface of body 7 is provided with one or more anti-spin slot 6；Hydroxyapatite is filled with the anti-spin slot 6；The body 7 is enclosed within the porous tantalum outer layer 4；The surface of porous tantalum outer layer 4 is threaded 5；Groove 8 is provided with end after the body 7 and the porous tantalum outer layer 4 combination.The tooth implant of this structure, makes tooth implant more be consolidated with being coupled for alveolar bone, improves the biocompatibility of tooth implant, makes the use of tooth implant relatively reliable persistently, extends the service life of tooth implant.
Description
Technical field
The utility model is related to a kind of tooth implant, more particularly to a kind of connection is firm, the reliable lasting, tooth implant of long service life.
Background technology
At present, it can be reproduced after human teeth's missing using dental filling, the various ways such as have a denture made, plant.Plant and be widely used in as a kind of method that reliability is high, using effect is good among anodontia reparation.
Traditional Dental implantion method retention effect is poor, is coupled and not enough consolidates, and releases rate height, not safe and reliable enough.The tooth implant biocompatibility of ordinary construction is undesirable, and inadequate durable, service life is not long.
Utility model content
In view of the foregoing defects the prior art has, the utility model aim to provide it is a kind of be coupled it is firm, reliable persistently, the tooth implant of long service life.
To achieve these goals, the utility model uses following technical scheme：Combined type tooth implant is made up of body and porous tantalum outer layer；The body is cylindrical structural；The rear body center, which is provided with below round platform hole, the round platform hole, is connected with regular hexagon hole, and screw is connected with below the regular hexagon hole；The bodies side surface is provided with one or more anti-spin slot；Hydroxyapatite is filled with the anti-spin slot；The body is enclosed within the porous tantalum outer layer；The porous tantalum superficies are threaded；After the body and the porous tantalum outer layer combination groove is provided with end.
As the improvement to the technical program, the anti-spin slot quantity is four.
As the improvement to the technical program, the porous tantalum outer layer porosity is between 50% and 80%.
Compared with the prior art, the utility model improves the biocompatibility of tooth implant by adopting the above-described technical solution, make being coupled for tooth implant and alveolar bone more consolidate, make the use of tooth implant relatively reliable persistently, extend the service life of tooth implant.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model embodiment.
In figure：1 round platform hole, 2 regular hexagon holes, 3 screws, 4 porous tantalum outer layers, 5 screw threads, 6 anti-spin slots, 7 bodies, 8 grooves.
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 tooth implant, as depicted in figs. 1 and 2, combined type tooth implant are made up of body 7 and porous tantalum outer layer 4；The body 7 is cylindrical structural；The posterior center of body 7 is provided with round platform hole 1, and the lower section of round platform hole 1 is connected with regular hexagon hole 2, and the lower section of regular hexagon hole 2 is connected with screw 3；The side surface of body 7 is provided with one or more anti-spin slot 6；Hydroxyapatite is filled with the anti-spin slot 6；The body 7 is enclosed within the porous tantalum outer layer 4；The surface of porous tantalum outer layer 4 is threaded 5；Groove 8 is provided with end after the body 7 and the porous tantalum outer layer 4 combination.
The quantity of anti-spin slot 6 is advisable with two to four.The present embodiment uses four.
The preferred macroporosity of the porous tantalum outer layer 4, it is proposed that porosity is between 50% and 80%.
The screw thread of porous tantalum superficies has tooth-shape structure, will increase the contact area with sclerotin, realizes laminating well.This aspect forms certain squeezing action, tooth implant is more consolidated with being coupled for alveolar bone, the safety and reliability of enhancing tooth implant in the oral cavity；On the other hand tooth implant is contacted with sclerotin closer, help lend some impetus to bone tissue growth and healing.
Porous tantalum outer layer improves the biocompatibility of total, is conducive to the fast quick-recovery of sclerotin and tooth implant to stablize lasting use.Groove filled with hydroxyapatite is after playing guiding bone tissue growth, promoting the effect of sclerotin sizing, moreover it is possible to plays a part of using newborn sclerotin maintenance, prevent that tooth implant from rotating.End groove also has the effect for starting bone tissue growth, promoting healing.
