Description
Technical field
This utility model relates to Dental Implant, particularly relates to a kind of implant tooth nail.
Background technology
Existing dental implant surgical, its planting process can only realize the reparation of a tooth, and plantation efficiency is very low, does not also consider practical situation and the demand of different patient simultaneously, cannot realize implanting personalizedly, thus have impact on the overall appearance of tooth after implanting.In addition, being implanted in alveolar bone or when using after implanting by the tooth nail of planting in order to install corona, because of being subject to the effect of alternating force, easily cause the retainer in its structure occur loosening or come off, and then cause and plant the tooth situation such as unsuccessfully.
Utility model content
This utility model aims to provide a kind of implant tooth nail, and this implant tooth nail connects reliable, and alternating force can be avoided to disturb, and greatly can improve and plant tooth efficiency.
To achieve these goals, this utility model is by the following technical solutions:
An implant tooth nail, is characterized in that: it is made up of retainer, implant and extension spring; Described retainer is made up of erecting bed, maintenance platform and threaded rod; The upper end of described maintenance platform is fixed with at least two described erecting beds; Described threaded rod is fixed in the lower end of described maintenance platform; Described implant inside is provided with the through hole run through up and down; Described through-hole inner surface is provided with regular screw threads, and in through hole, bottom arranges described extension spring; Described threaded rod is connected with the upper end of extension spring, and with the regular screw threads corresponding matching of through-hole inner surface; Concaved circular cambered surface in an annular is formed between the top place of described threaded rod and the upper surface of described implant; The bottom of described implant is pointed, and outer surface is smooth arc surface.
As further optimization, the middle part appearance of above-mentioned implant is with trapezoidal thread or rectangular thread.And the thread form angle of above-mentioned trapezoidal thread is more than or equal to 90 °, be less than or equal to 135 °.By this setting, while this structural mechanics intensity of guarantee, increase the contact area of appearance and dental bed inner bone tissues in the middle part of implant, make osseous tissue be embedded in thread gaps, further increase its connective stability.
As optimizing further, above-mentioned erecting bed is biased tilt column again.By this setting, achieve and according to the practical situation of patient, and can select the optimum inclination angle of erecting bed, adapted to the demand of different patient, after implanting, its overall structure is more reliably attractive in appearance.
Above-mentioned erecting bed, is preferably two of axial symmetry distribution.By corresponding on two erecting beds, two coronas are installed, implant while namely achieving two adjacent teeths, be applicable to the patient that two adjacent teeths all need to repair; And its axial symmetry is distributed, improve its structural mechanical property further.
Above-mentioned erecting bed, above-mentioned maintenance platform and above-mentioned threaded rod can adopt conventional medical alloy, through one-body molded be integral type structure so that processing.
This utility model has following beneficial effect:
This utility model provides a kind of implant tooth nail, it not only achieves the reparation namely being completed at least two teeth by an implant surgery, substantially increases and plants tooth efficiency, but also according to the actual needs of patient, achieve and implant personalizedly, what adapted to different patient plants tooth demand.And the bottom of its implant is set to outer surface is the pointed of smooth arc surface, make its planform be approximately nail shape, appearance gradient is larger and round and smooth, and the resistance be subject to during implantation is less, facilitates implant procedure.In addition, in installation or use procedure, if when causing because of External Force Acting retainer to occur to loosen, then make its overall structure again keep close contact by elastic force, ensure that fixed effect.

Detailed description of the invention
Below by embodiment, this utility model is specifically described; what be necessary to herein means out is that 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 according to foregoing to this utility model.
Embodiment 1
As shown in figures 1-4: a kind of implant tooth nail, it is made up of retainer, implant 1 and extension spring 2; Its retainer is made up of erecting bed 3, maintenance platform 4 and threaded rod 5, and erecting bed 3, maintenance platform 4 and threaded rod 5 all adopt conventional medical titanium alloy, through one-body molded be integral type structure; The upper end of this maintenance platform 4 is fixed with the erecting bed 3 of two axial symmetry distributions; This erecting bed 3 is biased tilt column; The lower end retaining thread bar 5 of this maintenance platform 4; Its implant 1 inside is provided with the through hole 6 run through up and down; This through hole 6 inner surface is provided with regular screw threads, and in through hole 6, bottom arranges extension spring 2; Its threaded rod 5 is connected with the upper end noose of extension spring 2, and with the regular screw threads corresponding matching of through hole 6 inner surface; Concaved circular cambered surface 7 in an annular is formed between the top place of this threaded rod 5 and the upper surface of implant 1; The bottom 8 of this implant 1 is pointed, and outer surface is smooth arc surface; The middle part appearance of this implant 1 equals the trapezoidal thread 9 of 95 ° with thread form angle.
The overall structure of this implant tooth nail is connected by threaded engagement, easily produces self-locking, good stress performance; And by the growth of osseous tissue or adopt bone cement to be fixed on alveolar bone by the bottom of extension spring 2, its other end noose is connected on threaded rod 5, indirectly achieve retainer and bottom alveolar bone close contact all the time, also continue to apply active force, to resist the work of outside alternating force in real time to its overall structure simultaneously.In addition, concaved circular cambered surface in the annular formed by the structural design of uniqueness, increase the contact area between itself and osseous tissue, for osteogenesis provides certain space, be conducive to sclerotin and grow healing fast, substantially reduce the restore cycle, be conducive to the combination of this artificial structure and alveolar bone, it connects the displacement that closely not easily gets loose.
