Description
Technical field
This utility model relates to implant tooth, relates in particular to a kind of canine implant.
Background technology
In currently available technology, adopting in oral cavity canine implant is to repair a mouthful best method for inner teeth gear disappearance, manyly with the having a denture made of routine, the insoluble intractable case of dental filling method, can obtain good curative effect by implantable artificial Dental Implant.
Existing canine implant mostly at least includes a plurality of parts such as implantation piece, retention means and screw.In its slightly simple structural design, be generally by screw, retention means and implantation piece to be connected and fixed, after a corona is installed in this retention means again again, to realize the implantation of artificial tooth.But along with the development of this technology, also progressively there are some technical problems in its project organization, and this just requires the design of more optimizing, such as: after further improving canine implant and implanting with body bone tissue between the compactness that is connected, to prevent loose or dislocation; Further simplified structure design, simplifies and plants tooth process operation; Further improve its mechanical property and biocompatibility etc.
Utility model content
For development trend and the requirement of this technology, this utility model aims to provide a kind of canine implant, and this canine implant is simple in structure, convenient to be implanted, connect reliably, and has good biocompatibility and stress performance concurrently.
To achieve these goals, this utility model is by the following technical solutions:
A canine implant, is characterized in that: it is comprised of implantation piece and retention means; Described implantation piece adopts porous tantalum product, and its porosity is 60%～70%; Described implantation piece inside is provided with groove, and this groove lower side is provided with regular screw threads; The bottom of described retention means is threaded rod, the regular screw threads corresponding matching of this threaded rod and implantation piece inner groovy lower side; The top of described retention means is spindle shape, concaved circular cambered surface in forming between its maximum gauge place and described implantation piece upper surface; Described implantation piece outer surface of upper is provided with annular groove.
As the improvement to the technical program, the top of above-mentioned retention means and the threaded rod of its underpart are one-body molded.This arranges the further structure of simplifying retention means, is convenient to manufacture.In application by the top of this retention means and corona corresponding matching, when having realized artificial tooth and implant.
As the improvement to the technical program, the quantity of above-mentioned annular groove is 1 to 3.
As the improvement to the technical program, above-mentioned annular groove is more than or equal to 0.2mm apart from the distance of described implantation piece upper surface, is less than or equal to 0.3mm.
As the further improvement to the technical program, above-mentioned implantation piece lower external face is with angular thread.
As the further improvement to the technical program, the tooth form angle of above-mentioned angular thread is more than or equal to 30 °, is less than or equal to 80 °.
The utlity model has following beneficial effect:
1, the regular screw threads that its implantation piece and retention means are arranged by self are connected, and easily produce self-locking, and good stress performance, and the setting of further having saved screw, simplify the structure;
2, its underpart angular thread has promoted its self tapping, makes implantation process more efficient and convenient, has greatly improved the success rate of plantation, has promoted clinical application effect;
3, by unique structure, formed interior concaved circular cambered surface, greatly shortened the restore cycle, and this artificial structure is closely connected with fastening with alveolar bone, displacement is difficult for getting loose;
4, its implantation piece itself adopts porous tantalum product, well met its mechanical property, improved stress performance, also greatly increased its biocompatibility simultaneously, improve service life and implanted comfort level, increase stability and anti-verticity after this artificial prosthesis is implanted, greatly improved the success rate of plantation;
5, implantation piece outer surface of upper is with circumferential annular groove, increased the contact area with human body, for osteogenesis provides certain space, be conducive to the healing of sclerotin Fast Growth, and the deadweight that has alleviated Dental Implant assembly, is conducive to the combination of assembly and human body, promote comfort.
Accompanying drawing explanation

The specific embodiment
Below by embodiment, this utility model is specifically described; be necessary to be pointed out that at this 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 to this utility model according to foregoing.
Embodiment: as Figure 1-3, a kind of canine implant, it is comprised of implantation piece 1 and retention means 2; Its implantation piece 1 adopts porous tantalum product, and its porosity is 60%～70%, and this porous tantalum product specifically can adopt method preparation described in patent 201110296515.7; This implantation piece 1 inside is provided with groove 3, and groove 3 lower side are provided with regular screw threads; The bottom of its retention means 2 is threaded rod 4, the regular screw threads corresponding matching of this threaded rod 4 and implantation piece 1 inner groovy 3 lower side; The top 5 of its retention means 2 is spindle shape, concaved circular cambered surface 7 in forming between its maximum gauge place 6 and implantation piece 1 upper surface; Its implantation piece 1 lower external face is the angular thread 8 of 60 ° with tooth form angle; Its implantation piece 1 outer surface of upper is provided with two annular grooves 9, and this annular groove 9 equals 0.3mm apart from the maximum distance of implantation piece 1 upper surface; The top 5 of its retention means 2 adopts medical titanium alloy one-body molded with the threaded rod of its underpart 4, and further by the top of this retention means 25 and corona corresponding matching, has realized artificial tooth implantation.
In this example, concaved circular cambered surface 7 in forming between the upper surface of implantation piece 1 and the maximum gauge place 6 of retention means 2, such structure makes to have formed an annular healing district between retention means 2 outer surfaces and implantation piece 1 upper surface.This design forming the matching surface of its structure and oral cavity bone bed.On this matching surface, the synosteosis that the growth of bone bed and artificial growth dentification are firm, thus canine implant is fixed, promote it to survive.The osteogenesis that is designed in healing district provides larger spatial accommodation, has accelerated osteogenesis process, has also accelerated post-operative recovery process.Meanwhile, because the associativity of this structure and human body bone is better, human body sensory is more naturally comfortable, and foreign body sensation also reduces greatly, and resistance to chewiness is enhanced.
Cannelure 9 has the effect that starts the growth of bone bed, holds area of new bone equally.Meanwhile, due to its loop configuration, the area of new bone of shaping can also play snap action to canine implant, makes its maintenance more stable, is difficult for occurring loosening.
