Abstract
The utility model discloses a dental implant which comprises a mother root and a cross root. The mother root is divided into an abutment at the upper end, a neck portion at the middle end and a root portion at the lower end, and the root portion is provided with an outer thread; and a porous tantalum layer is covered on the outer surface of the cross root, the middle of the cross root is provided with a screw hole, an inner thread on the screw hole is matched with the outer thread on the root portion of the mother root, and two ends of the outer surface of the cross root are provided with outer threads. The dental implant with such structure can be well fixed and is difficult to move after implantation, good in biocompatibility and capable of easily achieving osseointegration, and instant stress effects and long-term stability are greatly improved.
Description
Technical field
This utility model relates to a kind of tooth implant, relates in particular to all good tooth implants of a kind of at once stressed effect and long-term steadiness.
Background technology
At present, canine implant has obtained widely clinical practice as the effective ways for the treatment of anodontia.The tooth implant that canine implant adopts is usually by vertical implantation dental bed and for single, and this structure and implantation are so that the at once stressed effect of tooth implant and long-term steadiness are relatively poor.After plantation was finished, the time that usually needs to wait for some months could be installed corona made implantation body stressed, namely force-applied after can't realizing planting.And the firm power that traditional tooth implant structure and implantation are not enough to provide powerful makes osseous tissue realize rebuilding and forming firm physiological with implantation body being combined under disturbing than the circlet border.
The utility model content
In view of the foregoing defects the prior art has, this utility model aims to provide all good tooth implants of a kind of at once stressed effect and long-term steadiness.
To achieve these goals, this utility model by the following technical solutions: tooth implant comprises parent root and horizontal root; Described parent root is divided into base station, the cervical region of middle-end and the root of lower end of upper end, has external screw thread on the described root; Described horizontal root outer surface is coated with the porous tantalum layer, and horizontal root middle part has screw, and the external screw thread on the female thread on the described screw and the described parent root root is complementary, and described horizontal root outer surface two ends have external screw thread.
For the ease of implant procedure, effectively realization coupling, described parent root root has tapering.
For the ease of processing and implant procedure, the external screw thread tooth form at described horizontal root outer surface two ends is triangle.
For the ease of processing and implant procedure, the external screw thread tooth form angle at described horizontal root outer surface two ends is 60 °.
Compared with the prior art, this utility model makes tooth implant can realize good maintenance after plantation is finished owing to adopted technique scheme, be difficult for displacement, good biocompatibility is realized the bone integration easily, and stressed effect and long-term firm performance all improve greatly at once.
Description of drawings
Fig. 1 is the structural representation of this utility model embodiment.
The specific embodiment
Below by embodiment this utility model is carried out concrete description; be necessary to be pointed out that at this following examples only are used for this utility model is further detailed; 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 to this utility model according to foregoing.
Embodiment: a kind of tooth implant, as shown in Figure 1, tooth implant comprises parent root 1 and horizontal root 2.Parent root 1 is divided into base station 3, the cervical region 4 of middle-end and the root 5 of lower end of upper end.Has external screw thread on the root 5.Horizontal root 2 outer surfaces are coated with porous tantalum layer 8, and horizontal root 2 middle parts have screw 6, and the external screw thread on the female thread on the screw 6 and the root 5 is complementary.Horizontal root 2 outer surface two ends have external screw thread 7.
When implanting tooth implant, parent root 1 and horizontal root 2 are connected with external screw thread on the root 5 by the female thread on the screw 6.Parent root 1 is vertically implanted in the dental bed, and horizontal root 2 is laterally implanted in the dental bed.The external screw thread 7 at horizontal root 2 outer surface two ends is for the be connected location of horizontal root 2 with osseous tissue.
Because the structure that has adopted parent root 1 and horizontal root 2 to combine decomposes on the horizontal root 2 so that the suffered external force of corona is transmitted after part is absorbed by the high density cortical bone on dental bed top, horizontal root 2 then transmits by its two ends and decomposes on the high density cortical bone.Like this, corona is stressed all to be decomposed on the high density cortical bone through tooth implant, and Stability Analysis of Structures is stressed even, is difficult for being shifted because local pressure is uneven, and stressed effect is improved at once.
Porous tantalum layer 8 is used for the growth of guiding and hold bone tissue, and realization tooth implant firm physiological between osseous tissue is combined, and improves the long-time stability of plantation.
For the ease of processing and implant procedure, suggestion external screw thread 7 tooth forms are triangle, and the tooth form angle is 60 °.
For the ease of implant procedure, effectively realization coupling, root 5 has tapering.Suggestion root 5 taperings are between 5 degree are spent to 10.
The preferred titanium of dental implant materials or titanium alloy also can be other compact metal materials.
