Description

Dental implant device

The present invention relates to a kind of dental implants.

The applicant thinks that immediate technology is that (concrete going up says that its model is Stryker FinImplant type No for address: Kalamazoo, the MI49001) implant of being sold in Stryker Dental Implants company.260-135-008 and equivalent.The present invention is provided with one and has a polyhedron (hexagon portion) and a link that is adjacent the tapering that connects, and it has the interface that cooperatively interacts and comes the attaching pseudodont and avoid entering foreign material, but aforementioned implant does not have.Aforementioned techniques is not used in the rotation-preventing mechanism of butt joint, does not also disclose to have spiral fluted cylindrical root shape implant fixed part.

Main purpose of the present invention provides a kind of implanting device of avoiding entering foreign material, prevents to assemble saliva, blood, antibacterial, soft tissue sandwiches or other materials.

Another object of the present invention provides a kind of implanting device, and it comprises that a tapering connects a docking section of matching.

Another purpose of the present invention provides a kind of multiduty implanting device, but the various artificial tooth of attaching docking section on it.

A further object of the present invention provides a hexagon part, and it is next among the implantation portion insertion jawbone to be convenient to apply necessary power, and prevents the butt joint rotation on each dental implants.

Of the present inventionly advance a purpose and provide a kind of cheap and handy implanting device.

Also will represent further purpose of the present invention in the detailed description below, following detailed description does not just play the qualification effect in order to disclose invention.

Can the present invention be described more clearly with reference to accompanying drawing, in the accompanying drawing:

Fig. 1 is the side view of a preferred embodiment, represents screw thread shaft type tooth root shape implantation fixed part, and it has a smooth articulation diminished shaft;

Fig. 2 shows a bright alternate embodiment, and wherein the smooth articulation diminished shaft comprises an end of thread, and the partial sectional view of anchoring section is shown along the line among Fig. 52;

Fig. 3 is the side view of one second alternate embodiment, and it is that a blade type tooth root shape is implanted fixed part;

Fig. 4 is the partial view of one the 3rd alternate embodiment, and it is that a spiral flute type post root shape is implanted the fastening part;

Fig. 5 is the vertical view of second alternate embodiment;

Fig. 6 illustrates the partial sectional view of one the 4th alternate embodiment, and it has a dismountable butt joint; And

Fig. 7 shows the state of ingredient after assembling among bright Fig. 6.

Now referring to Fig. 1, by label 10 indications, it comprises root shape implantation fixed part 20 and docking section 100 to the preferred embodiments of the present invention generally.The root shape is implanted fixed part 20 and is comprised anchoring section 30 and joining section (cervical region) 40.

Anchoring section 30 comprises and is threaded 34 axle 32, and the fully spaced apart so that bone that inserts therebetween of this screw thread occupies interval therebetween and reaches best anchoring effect.On axle 32 also can be a blade type, as the label among Fig. 3 32 " indicated axle, the spaced apart in parallel to each other rigidly axle 32 that is installed in of several leaf dishes ".Axle 32 of another kind of type are shown among Fig. 4, and it is one and has the spiral fluted cylinder.

As shown in Figure 1, joining section 40 is connecting an end of axle 32, and it comprises post portion 60, tapering 70 and multiaspect body 80, and it is adjacent with said sequence.In a preferred embodiment, multiaspect body 80 is hexagons.

The middle part of the part of post portion 60, tapering 70 and multiaspect body 80 and axle 30 is passed in lengthwise chamber, center 90, and this represents the most clearly in Fig. 2.In preferred embodiment and alternate example shown in Figure 2, chamber 90 is extended to anchoring section 30 directions with it and is attenuated.In alternate embodiment shown in Figure 2, there is a bottom of thread 92 90 the end in the chamber.It should be noted that for preferred embodiment shown in Figure 1 and alternate embodiment shown in Figure 2, even the screw thread that extension bar 120 is not matched of preferred embodiment, used chamber 90 still is identical.

Docking section 100 has head 110, and head has the elongate bars of doing with it together 120, as shown in Figure 1.Head 110 changes with respect to the correction according to the required depth of parallelism of the angle of the longitudinal axis of docking section 100, and shown in the figure is 0 ° of butt joint, so that describe the present invention.The depth of parallelism is undesirable inadequately, when being provided with to such an extent that be not parallel to each other, will cause that the depth of parallelism is not enough to fixed part 20.In preferred embodiment shown in Figure 1, elongate bars 120 interlock glossily the inwall of center cavity 90, thereby locks it in place.The interlock of the metal to metal of the inwall in bar 120 and chamber 90 maintains top 100 and seals for the clearance spaces in the chamber 90 forms, thereby prevents to gather saliva, blood or other perishabless.

In Fig. 2, the threaded 130 that docking section 100 ' comprise is installed in bar 120 ' top end rigidly '.Threaded is cooperating the bottom of thread 92 in chamber 90.

Shown in Fig. 3 and 4, " be similar to corresponding part among Fig. 1 and 2 substantially with 20 , just anchoring section 30 " and axle 32 of 30 " is respectively blade and spiral flute type with 32 to the fixed part 20 of the second and the 3rd alternate embodiment.

The 4th alternate embodiment as shown in Figure 6, it is represented by label 10 " " generally.The used root shape of dental implant device 10 " " implants fixed part 20 " " and

installs

10 and 10 ' used corresponding identical.Fixed part 20 " " can be any kind (spiral, blade or a column).Butt joint 110 " " is removably injected in the fixed part 20 " ", and forms not rotatable cooperation thereon.Inner chamfering edge 112 " " cooperate following tapering 70 " ".The connecting face-to-face of edge 112 " " and tapering 70 " " forms that a kind of sealing prevents the infiltration of saliva, antibacterial, exudate or soft tissue folds into or other exotics enter.Inner multiaspect cover 114 " " are cooperating multiaspect body 80 " ", and anti-ly stop butt joint 110 " rotation.

Bar 120 " " inserts in the centre bore 111 " " of butt joint 110 " " coaxially, and at one end pin portion 130 " " injects among the edge 112 " " and engages with chamber 90 " " in the fixed part 20 " ".This juncture is identical with first alternate embodiment with preferred embodiment.Unique difference is that bar 120 " " has an internal sleeve 122 " " and allows its rotation, and makes sleeve pipe 124 " " contact counterbore face 116 " ", thereby top 110 " " are fixed downwards.

Screw division 200 " " is used for an artificial tooth (fixed or dismountable) and is fixed to butt joint 110 " ", represents the most clearly as Fig. 7.

The best appreciated of understanding objects and advantages of the present invention is shown in the description of front.Can make various embodiment from basic thought of the present invention.It should be understood that the thing that discloses at this only may be interpreted as illustrative, and do not have limited.

Said apparatus can be used for tooth and implants.
