Description
Technical field
This utility model relates to canine implant, relates in particular to a kind of implant dental assembly.
Background technology
In known technology, adopting implant dental assembly to carry out canine implant in oral cavity is to repair a mouthful best method for inner teeth gear disappearance at present.Existing implant dental assembly generally includes the parts such as implantation piece, retention means and screw, and it is 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 in clinical practice, it is to be overcome that this technology still exists some technological deficiencies to have, for example implant dental assembly self tapping is poor, be difficult to implant; After implanting, be connected defective tightness with body bone tissue, easily loose or dislocation; Mechanical property and biocompatibility are poor; Mostly be multiple independently assembling parts and form, the identical components diversity in each structural design is larger, does not have general applicability, plants tooth process operation comparatively loaded down with trivial details etc.
Utility model content
In view of the foregoing defects the prior art has, this utility model aims to provide a kind of implant dental assembly, and this implant dental assembly is simple in structure, self tapping is good, conveniently implant, stress performance is good, connection is reliable, and has good biocompatibility concurrently.
To achieve these goals, this utility model is by the following technical solutions:
A kind of implant dental assembly, is characterized in that: it is made up 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.
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, realized artificial tooth implant time.
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 °.
This utility model is by adopting technique scheme, and its implantation piece and retention means are connected by regular screw threads, easily produce self-locking, and good stress performance, and the setting of further having saved screw, simplify the structure; Its implantation piece appearance bottom angular thread has promoted its self tapping, makes implantation process more efficient and convenient; Its implantation piece itself adopts porous tantalum product, well meet its mechanical property, improve stress performance, also greatly increased the biocompatibility of this tooth plantation assembly 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.
Brief description of the drawings

Detailed description of the invention
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 shown in Figure 1-2, a kind of implant dental assembly, it is made up 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; The top 5 of its retention means 2 adopts medical titanium alloy one-body molded with the threaded rod 4 of its underpart, 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.After implantation completes, due to the existence in this healing district, human bone cell can be rapidly to healing district growth inside, until by its filling.With respect to traditional implant dental assembly structure, such structural priming bone tissue growth is obviously accelerated, and the restore cycle shortens greatly.And, because bone cell growth is filled annular healing district, its self-assembling formation encirclement to implant dental assembly and fastening, it is rooted among alveolar bone firmly, displacement is difficult for getting loose.Meanwhile, such mode of healing obviously strengthens healing effect, and implant dental assembly and human body alveolar bone more become to combining together, uses more freely comfortable.This series of advantage, makes the plantation success rate of implant dental assembly of this structure apparently higher than traditional structure, and result of use after surgery also further strengthens, and patient chews more reliably freely.
