Abstract
The invention discloses a dental implant. The dental implant comprises an artificial tooth root 1, a healing abutment 2 and a thread body 3. The healing abutment 2 is connected and fixed to the upper end of the artificial tooth root 1 by the thread body 3. The healing abutment 2 is in a contact fit relationship with the artificial tooth root 1 by a matching surface 11. A concave healing cambered surface 4 is arranged between the largest-diameter part 7 of the healing abutment 2 and the matching surface 11. The upper part of the artificial tooth root 1 is provided with rectangular screw threads 6 and the lower part of the artificial tooth root 1 is provided with triangular threads 5. The dental implant improves structure-bone integrity, structural biocompatibility and high mechanical strength, reduces complication, has high simulation ability and is firm and comfortable in use.

Summary of the invention
In view of the foregoing defects the prior art has, the tooth implant that the present invention aims to provide that a kind of Integrated implant is good, biocompatibility is high, mechanical strength is high, few intercurrent disease, emulation are high.
To achieve these goals, the present invention by the following technical solutions: a kind of tooth implant, is made up of artificial tooth root, gingival former and threaded body; Described gingival former is connected and fixed on described artificial tooth root upper end by described threaded body; Described gingival former to be contacted with described artificial tooth root by mating surface and coordinates; The healing cambered surface of indent is provided with between described gingival former maximum gauge place and described mating surface; Rectangular thread is established on described artificial tooth root top, and angular thread is established in bottom.
As the improvement to the technical program, the surface of described artificial tooth root is with rough coatings.
As the improvement to the technical program, described threaded body is screw.
As the improvement to the technical program, described healing cambered surface is arc surface.
As the improvement to the technical program, the difference of described artificial tooth root upper surface external diameter and internal diameter is more than or equal to 0.4mm, is less than or equal to 0.5mm.
As the improvement to the technical program, the rectangular thread on described artificial tooth root is more than or equal to 1.4 with the axial length ratio of angular thread, is less than or equal to 1.5.
As the improvement to the technical program, described rectangular thread helical pitch is 0.8mm.
As the improvement to the technical program, described angular thread helical pitch is 0.6mm.
As the improvement to the technical program, the upper end surface of described artificial tooth root is provided with ladder blind hole, and described ladder blind hole latter end is with female thread; Described gingival former is provided with ladder hole; Described gingival former is vertically placed in described ladder blind hole; Described threaded body by described ladder hole, and is connected with the screw-internal thread fit of described ladder blind hole latter end.
Compared with the prior art, the present invention is owing to have employed technique scheme, improve the Integrated implant of structure, improve the biocompatibility of structure, make the mechanical strength of tooth implant higher, decrease the generation of complication, make tooth implant have higher emulation, use more firmly comfortable.

In figure: 1 artificial tooth root, 2 gingival formers, 3 threaded bodies, 4 healing cambered surfaces, 5 angular threads, 6 rectangular threads, 7 maximum gauge places, 8 upper surfaces, 9 ladder blind holes, 10 female threads, 11 mating surfaces, 12 ladder holes.
Detailed description of the invention
Below by embodiment, the present invention is specifically described; what be necessary to herein means out is that following examples are only for being further detailed the present invention; can not be interpreted as limiting the scope of the invention, those skilled in the art can make some nonessential improvement and adjustment according to foregoing to the present invention.
Embodiment: a kind of tooth implant, as Figure 1-4, tooth implant is made up of artificial tooth root 1, gingival former 2 and threaded body 3; Described gingival former 2 is connected and fixed on described artificial tooth root 1 upper end by described threaded body 3; Described gingival former 2 to be contacted with described artificial tooth root 1 by mating surface 11 and coordinates; The healing cambered surface 4 of indent is provided with between described gingival former 2 maximum gauge place 7 and described mating surface 11; Rectangular thread 6 is established on described artificial tooth root 1 top, and angular thread 5 is established in bottom.
The material of tooth implant is the titanium alloy with high-biocompatibility, and postoperation recovery, with rough coatings, to strengthen its biocompatibility, is convenient in the surface of artificial tooth root 1.
Threaded body 3 adopts bolt structure usually, also can adopt bolt, also can adopt the combination of stud and nut.
The setting of healing cambered surface 4 makes to form a healing district between artificial tooth root 1 and gingival former 2, holds and promotes Bone Ingrowth and Integrated implant, impelling finally surviving of tooth implant.For the ease of processing, described healing cambered surface 4 is arc surface.
Prove after tested, the difference (as shown in Figure 1, being M) of artificial tooth root 1 upper surface 8 external diameter and internal diameter is more than or equal to 0.4mm, when being less than or equal to 0.5mm, both ensure that sufficient space Bone Ingrowth, and has taken into account again enough structural strengths.
Be different from general structure and only angular thread is set, artificial tooth root 1 top is provided with rectangular thread.Rectangular thread, because of its shape facility, has higher mechanical strength, can promote overall anti-masticatory force, makes tooth implant in use as firm as natural dermal tooth, and need not worry the food of daily really up to the mark, Chewy, simulation performance is better.Experimentally Data Summary is learnt, the rectangular thread 6 on artificial tooth root 1 is more than or equal to 1.4 with the axial length ratio (as shown in Figure 1, the ratio for L and S) of angular thread 5, and when being less than or equal to 1.5, the serviceability of structure is more excellent; The preferred 0.8mm of rectangular thread 6 helical pitch, the preferred 0.6mm of angular thread 7 helical pitch.
Described gingival former 2 is connected and fixed on described artificial tooth root 1 upper end by described threaded body 3, the present embodiment in the following way: upper surface 8 place of described artificial tooth root 1 is provided with ladder blind hole 9, and described ladder blind hole 9 latter end is with female thread 10; Described gingival former 2 is provided with ladder hole 12; Described gingival former 2 is vertically placed in described ladder blind hole 9; Described threaded body 3 by described ladder hole 12, and is connected with the female thread 10 of described ladder blind hole 9 latter end.
