Description

One Dental Implant fixture

Technical field

This utility model relates to Dental Implant, particularly relates to a Dental Implant fixture.

Background technology

Dental Implant, with its good repairing effect, has become the first-selected repair mode of agomphosis patient.In Dental implantion process, need to be implanted into one at dental bed in advance and plant tooth fixture, then after planting tooth fixture and the long jail of dental bed, then hold installation one corona to realize the implantation of artificial tooth thereon.Along with the development of this technology clinical practice, also many technical problems have been there is: its planting process can only realize the reparation of a tooth, plantation inefficiency, do not consider practical situation and the demand of different patient simultaneously yet, cannot realize implanting personalizedly, thus have impact on the overall appearance of tooth after implanting; Be connected defective tightness with body bone tissue, when implanting neutralization use, because loosening or coming off easily appears in the effect corona being subject to alternating force, cause planting tooth failure etc.

Utility model content

This utility model aims to provide a Dental Implant fixture, and this is planted tooth fixture and connects reliable, alternating force can be avoided to disturb, greatly can improve and plant tooth efficiency, and overall appearance is more beautified after implanting.

To achieve these goals, this utility model is by the following technical solutions:

One Dental Implant fixture, 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 erecting bed is biased tilt column; 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, described extension spring is placed in bottom; Described threaded rod is connected with one end of extension spring, and with the regular screw threads corresponding matching of through-hole inner surface; The middle part appearance of described implant is with trapezoidal thread or rectangular thread, and lower external is with angular thread.

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.Meanwhile, can select the optimum inclination angle of erecting bed according to patient's practical situation, adapted to the demand of different patient, its structure is more reliably attractive in appearance.

As further improvement, in the middle part of above-mentioned implant, the thread form angle of the trapezoidal thread of appearance is more than or equal to 90 °, is less than or equal to 135 °.By the setting of trapezoidal thread or rectangular thread, while this structural mechanics intensity of guarantee, increase the contact area of itself and dental bed inner bone tissues, osseous tissue is embedded in thread gaps, and then further increases connective stability.

As further improvement, the thread form angle of the angular thread of above-mentioned implant lower external is more than or equal to 30 °, is less than or equal to 80 °.The angular thread of lower external improves self tapping, implants more efficient and convenient, and substantially increases plantation success rate.

As further improvement, the apparent trapezoidal thread of above-mentioned implant or rectangular thread are more than or equal to 1.4 with the axial length ratio of angular thread, are less than or equal to 1.5.

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 Dental Implant fixture, its overall structure is connected by threaded engagement, easy generation self-locking, good stress performance, again by the growth of osseous tissue or adopt bone cement to be fixed on the alveolar bone of bottom by extension spring bottom, its other end noose is connected on threaded rod, achieve retainer and bottom alveolar bone close contact all the time, also continue to apply active force to its overall structure simultaneously, to resist outside alternating force effect in real time, in use, if there is retainer to loosen because of external force, then it is made again to keep close contact by elastic force, ensure that fixed effect.In addition, 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.

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 to 3: a Dental Implant fixture, 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, extension spring 2 is placed in bottom; 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; The middle part appearance of this implant 1 equals the trapezoidal thread 7 of 100 ° with thread form angle, lower external equals the angular thread 8 of 60 ° with thread form angle, and trapezoidal thread 7 equals 1.45 with the axial length ratio of angular thread 8.

In clinical practice, by the growth of osseous tissue or adopt bone cement to be fixed on the alveolar bone of bottom by the bottom of extension spring 2, its other end noose is connected on threaded rod 5 to continue to apply elastic force to retainer, ensure that its all the time with implant 1 close contact, active force is applied to structure entirety simultaneously, make itself and bottom alveolar bone close contact all the time; If because outside alternating force makes connection loosing during use, then extension spring 2 makes it again keep close contact by elastic force, and then ensure that fixed effect.In addition, by corresponding on two erecting beds 3, artificial tooth or corona are installed, once plant the implantation namely achieving two artificial tooths, and the practical situation of overall appearance according to patient oral cavity inner teeth gear, select the optimum inclination angle of erecting bed 3, adapt to differently patient personalized plant tooth demand, it is more reliably attractive in appearance that it plants tooth effect.
