Description
Technical field
This utility model relates to canine implant, particularly relates to a kind of dental implant.
Background technology
Mouth inner teeth gear disappearance can have a strong impact on to our healthy generation, very easily brings out other body illnesses.And about the Therapeutic Method that mouth inner teeth gear lacks, usually adopt the artificial outside mode implanting a dental implant to repair at present.But because its structural design is different perfect not to the utmost, existing dental implant be connected not infirm, easy loose or dislocation between artificial tooth, with the connectivity of body bone tissue and biocompatibility poor.Its planting process can only realize the reparation of a tooth, and plantation inefficiency, does 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.
Utility model content
The purpose of this utility model is to provide a kind of dental implant, and this dental implant biocompatibility and connective stability better, greatly can improve and plant tooth efficiency, and overall appearance is more beautified after implanting.
The purpose of this utility model is achieved in that
A kind of dental implant, is characterized in that: it is made up of retainer and implant; 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 is divided into upper and lower two parts, and two parts are porous tantalum product up and down, and wherein, the porosity of lower part is greater than the porosity of upper part; Described implant inside is provided with screwed hole; Described threaded rod and described screwed hole corresponding matching.
The upper and lower two-part porosity of above-mentioned implant is respectively 30% ~ 40% and 60% ~ 70%.The lower part of the implant of its larger porosity, be convenient to more alveolar bone tissue and grow into hole to combine closely with this implant, and reach best biocompatibility, the porosity that its upper part is less simultaneously not only can be combined closely with osseous tissue, also give overall structure higher mechanical strength, to resist the effect of horizontal lateral force.
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.
Above-mentioned screwed hole is specifically set to shoulder hole, and the lower side of shoulder hole is provided with screw thread; The screw thread corresponding matching of above-mentioned threaded rod and described shoulder hole lower side.
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, simplify its structure.
This utility model has following beneficial effect:
This utility model provides a kind of dental implant, namely it does not complete the reparation of at least two teeth by means of only an implant surgery, substantially increase and plant tooth efficiency, but also according to the actual needs of patient, achieve and implant personalizedly, what adapted to different patient plants tooth demand.Its implant entirety all adopts porous tantalum product, can make Bone Ingrowth and structure of growing in being formed, considerably increase biocompatibility, implant after stability and anti-rotation performance, improve service life and implant comfort level; Further, the lower part of the implant of its larger porosity, be convenient to alveolar bone tissue and grow into hole to combine closely with this artificial outer implant, and reach best biocompatibility, the porosity that its upper part is less simultaneously not only can be combined closely with osseous tissue, also gives overall structure higher mechanical strength, to resist the effect of horizontal lateral force, improve stress performance, substantially increase the success rate of plantation.

Detailed description of the invention
Be below this utility model preferred embodiment, and be not intended to limit protection domain of the present utility model.
Embodiment 1
As shown in Figures 1 to 3: a kind of dental implant, it is made up of retainer and implant 1; Its retainer is made up of erecting bed 2, maintenance platform 3 and threaded rod 4, and erecting bed 2, maintenance platform 3 and threaded rod 4 all adopt conventional medical titanium alloy, through one-body molded be integral type structure; The upper end of this maintenance platform 3 is fixed with the erecting bed 2 of two axial symmetry distributions; This erecting bed 2 is biased tilt column; The lower end retaining thread bar 4 of this maintenance platform 3; Its implant 1 is divided into upper and lower two parts 5,6, and two parts 5,6 are porous tantalum product up and down; Wherein, the porosity of lower part 6 is 60% ~ 65%, and the porosity of its upper part 5 is 30% ~ 36%, and this porous tantalum product specifically can adopt method preparation as described in patent 201110296515.7; This implant 1 inside is provided with shoulder hole 7, and the lower side of shoulder hole 7 is provided with screw thread; The screw thread corresponding matching of its threaded rod 4 and shoulder hole 7 lower side.
Plant in tooth application, by corresponding on the erecting bed 2 of two axial symmetry distributions, artificial tooth is installed, namely by once planting the implantation just 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 2, adapt to differently patient personalized plant tooth demand, it is more reliably attractive in appearance that it plants tooth effect.In addition, by adopting screw-type to be connected implant 1 and retainer, when there is the situations such as fracture when top erecting bed 2, be convenient to change.
