Description
Technical field
The utility model relates to oral cavity canine implant, particularly relates to a kind of tooth-implant nail.
Background technology
It is by artificial growth one artificial tooth that treatment oral cavity inner teeth gear lacks good mode.Existing canine implant is mostly designed to be similar to nail shape structure, to fix by hammering into alveolar bone, and then installs the implantation that artificial tooth realizes artificial tooth.But because its design is perfect not to the utmost, mostly also there is later stage installation procedure comparatively loaded down with trivial details, plantation part and be connected not infirm, easy loose or dislocation between artificial tooth, with the connectivity of body bone tissue and the defect such as biocompatibility is poor.In addition, existing canine implant, also cannot realize selecting suitable implant angle according to different patient's actual conditions and demand, thus affects the overall appearance that tooth-implanting implants rear oral cavity inner teeth gear.
Utility model content
The purpose of this utility model is to provide a kind of tooth-implant nail, and this tooth-implant nail is an overall structure, simple installation is firm, biocompatibility is better, and after implanting, entirety is comparatively attractive in appearance.
The purpose of this utility model is achieved in that
A kind of tooth-implant nail, is characterized in that: it is the entirety be made up of implanting portion and retainer; The top of described retainer is biased tilt column; The middle part of described retainer is maximum gauge place; A groove is formed between the maximum gauge place of described retainer and the upper surface of described implanting portion; Described implanting portion is made up of body and adhesion layer; Described adhesion layer is porous tantalum product, and is attached to the body appearance of described implanting portion.
The adhesion layer of above-mentioned implanting portion is porous tantalum product, and its porosity is 60% ~ 70%.Through adopting the adhesion layer of the implanting portion of the porous tantalum product of above-mentioned porosity, Bone Ingrowth can be made and structure of growing in being formed, thus organically combine as a whole with body bone tissue, while substantially increasing biocompatibility, also well meet its mechanical property, improve service life and implant comfort level, adding the stability after artificial prosthesis implantation and anti-rotation performance.This porous tantalum product can specifically adopt the preparations such as foam dipping method, die pressing.
The overall length of above-mentioned tooth-implant nail is 14.5mm, and wherein, the length of maximum gauge place to the upper surface of above-mentioned retainer is 4.6mm, and the length of the upper surface of maximum gauge place to the above-mentioned implanting portion of retainer is 1.5mm, and the length of above-mentioned implanting portion is 8.4mm.
The diameter at the maximum gauge place of above-mentioned retainer is 4.8mm, and the diameter of above-mentioned groove is 3.8mm.By this restriction, the degree of depth of groove is suitable for implanting rear bone tissue and grows into promote that gum heals, and while ensureing healing effect the best, ensure that its Structural strength calls.
The body part of above-mentioned implanting portion and above-mentioned retainer adopt conventional medical alloy one-body molded, adhere to the adhesion layer of above-mentioned implanting portion by bonding or sintering process in the body appearance of above-mentioned implanting portion.Wherein, adopt the implanting portion body part of conventional medical alloy, give the mechanical strength that overall structure is higher, to resist the effect of horizontal lateral force, and by arranging porous adhesion layer, be convenient to alveolar bone tissue and grow into hole to combine closely with tooth-implant nail, and reach best biocompatibility, combine closely with bone tissue.
The utility model has following beneficial effect:
1, its structure is overall a, good stress performance, is also convenient to produce and plant tooth process operation;
2, define groove by unique structural design, be convenient to human bone cell and be rapidly to this region growing, substantially reduce the restore cycle, and and then by this artificial structure and alveolar bone compact siro spinning technology and fastening, not easily get loose displacement;
3, the body part of its implanting portion adopts conventional medical alloy, impart the mechanical strength that overall structure is higher, to resist the effect of horizontal lateral force, and by arranging porous adhesion layer, Bone Ingrowth hole can be made and structure of growing in being formed, considerably increase biocompatibility, implant after stability and anti-rotation performance, improve service life and implant comfort level, and reach best biocompatibility, combine closely with bone tissue.
4, its retainer top is biased tilt column, installs after artificial tooth be beneficial to the rotation after preventing artificial tooth from installing through correspondence, more stable; Meanwhile, suitable angle of inclination can be selected according to patient's actual conditions, adapt to the demand of different patient, more reliably attractive in appearance.
Accompanying drawing explanation
Fig. 1 is the structural representation of tooth-implant nail described in the utility model embodiment 1.
Fig. 2 is the left view of Fig. 1.
Detailed description of the invention
Be below the utility model preferred embodiment, and be not intended to limit protection domain of the present utility model.
Embodiment 1
As shown in Fig. 1 ~ 2: a kind of tooth-implant nail, it is the entirety be made up of implanting portion 1 and retainer 2; The top of its retainer 2 is biased tilt column 3; The middle part of retainer 2 is maximum gauge place 4; A groove 5 is formed between the maximum gauge place 4 of retainer 2 and the upper surface of implanting portion 1; Implanting portion 1 is made up of body 6 and adhesion layer 7; This adhesion layer 7 is the porous tantalum product of porosity 65%, and is attached to body 6 appearance of implanting portion 1, and this porous tantalum product specifically can adopt method preparation as described in patent 201110296515.7; The overall length of this tooth-implant nail is 14.5mm, and wherein, the length of 5 to the upper surface, maximum gauge place of retainer 2 is 4.6mm, and the length of the upper surface of 5 to the implanting portion, maximum gauge place 1 of retainer 2 is 1.5mm, and the length of implanting portion 1 is 8.4mm; The diameter at the maximum gauge place 5 of retainer 2 is 4.8mm, and the diameter of groove is 3.8mm; Body 6 part of its implanting portion 1 and retainer 2 adopt conventional medical titanium alloy one-body molded, adhere to the adhesion layer 7 of implanting portion 1 by body 6 appearance being bonded in implanting portion 1; In the retainer 2 top correspondence being provided with biased tilt column 3, artificial tooth is installed, namely achieves the implantation of artificial tooth.
In clinical practice, the groove 5 that unique structural design is formed, is convenient to human bone cell and is rapidly to its superficial growth, until filled, its bone tissue growth is obviously accelerated, and the restore cycle shortens greatly, and make this tooth-implant nail be rooted in firmly among alveolar bone further, not easily get loose displacement.In addition, selected the angle of inclination that biased tilt column 3 is suitable by the actual conditions according to patient, adapt to the demand of different patient, more reliably attractive in appearance.
