Description
Technical field
The utility model relates to oral cavity canine implant, particularly relates to a kind of integral type tooth-implanting.
Background technology
Implant intraoral canine implant as outside, once the connectivity after implanting and between body bone tissue and biocompatibility, and the reliability of its structure self is the principal element affecting its result of use.Existing canine implant, be mostly multiple assembly to connect to form, its parts are many and complicated, and due to structural design imperfection, they or to there is biocompatibility poor, be connected defective tightness with body bone tissue, the defect of easy loose or dislocation, or it is poor to there is mechanical property, when suffering the effect of horizontal lateral force and the problem that easily ruptures, therefore await further.
Utility model content
The purpose of this utility model is to provide a kind of integral type tooth-implanting, and this integral type tooth-implanting has good biocompatibility and mechanical property concurrently, is connected closely reliable with tissue.
The purpose of this utility model is achieved in that
A kind of integral type tooth-implanting, is characterized in that: it for by implanting portion and retainer group in aggregates; Described implant part is 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; The middle part of described retainer is maximum gauge place, and forms an inner concave between the upper surface of the maximum gauge place of described retainer and described implanting portion; The top of described retainer is the Rotary-table shape of side with tangent plane.
The upper and lower two-part porosity of above-mentioned implanting portion is respectively 30% ~ 40% and 60% ~ 70%.By this setting, the lower part of the implanting portion of larger porosity, be convenient to alveolar bone tissue and grow into hole to combine closely with tooth-implanting, and reach best biocompatibility, the smaller porosity of its upper part not only can be combined closely with bone tissue simultaneously, also give overall structure higher mechanical strength, to resist the effect of horizontal lateral force.
The overall length of above-mentioned integral type tooth-implanting is 14mm, and wherein, the length of maximum gauge place to the upper surface of above-mentioned retainer is 4mm, 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 8.5mm.
The diameter at the maximum gauge place of above-mentioned retainer is 4.5mm, is 3.8mm with the diameter at the above-mentioned retainer place of the junction, upper surface of above-mentioned implanting portion.By this restriction, the acute angle type inner concave formed between the maximum gauge place of retainer and the upper surface of implanting portion, be convenient to implant the healing of rear gum, and healing effect is best.
The upper part of above-mentioned retainer and above-mentioned implanting portion, above-mentioned implanting portion and lower part, all realize mutual being fixedly connected with by welding or boning.Its connected mode is simple, and achieves that it to be connected respectively be one overall.
The utility model has following beneficial effect:
1, its overall structure is an entirety, and good stress performance is convenient to produce and plant tooth process operation;
2, define inner concave by unique structural design, substantially reduce the restore cycle, and by this artificial structure and alveolar bone compact siro spinning technology and fastening, not easily get loose displacement;
3, wherein, retainer top is the Rotary-table shape of side with tangent plane, can prevent artificial tooth from producing rotate by correspondence after installing artificial tooth, more reliable and more stable;
4, simultaneously, its implanting portion entirety all adopts porous tantalum product, Bone Ingrowth can be made and structure of growing in being formed, considerably increase biocompatibility, stability after implantation and anti-rotation performance, improve service life and implant comfort level, simultaneously, the further lower part of the implanting portion of its larger porosity, be convenient to alveolar bone tissue and grow into hole to combine closely with tooth-implanting, and reach best biocompatibility, the smaller porosity of its upper part not only can be combined closely with bone tissue simultaneously, also give 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 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 integral type tooth-implanting, it be by implanting portion 1 and retainer 2 groups in aggregates; Its implanting portion 1 is divided into upper and lower two parts 3,4, and wherein, upper part 3 is the porous tantalum product of porosity 36%, and lower part 4 is the porous tantalum product of porosity 65%, and this porous tantalum product specifically can adopt method preparation as described in patent 201110296515.7; ; The middle part of its retainer 2 is maximum gauge place 5, and shape type inner concave 6 in an acute angle between the upper surface of this maximum gauge place 5 and implanting portion 1; The top of retainer 2 is the Rotary-table shape of side with tangent plane 7; The overall length of this integral type tooth-implanting is 14mm, and wherein, the length of 5 to the upper surface, maximum gauge place of retainer 2 is 4mm, 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 8.5mm; The diameter at the maximum gauge place 5 of retainer 2 is 4.5mm, is 3.8mm with the diameter at retainer 2 place of the junction, upper surface of implanting portion 1; Its retainer 2 adopts medical titanium alloy product, and is achieved a fixed connection by welding with implanting portion 1, and the upper part 3 of implanting portion 1 and lower part 4 also realize mutual being fixedly connected with by welding; Side is with retainer 2 top of the Rotary-table shape of tangent plane 7, and corresponding installation artificial tooth, namely achieves the implantation of artificial tooth.
In clinical practice, the inner concave that unique structural design is formed, make to define an annular healing district between retainer 2 outer surface and upper surface, implanting portion 2, human bone cell can be rapidly to healing district growth inside, until filled, its bone tissue growth is obviously accelerated, and the restore cycle shortens greatly; Due to bone cell growth fill annular healing district, which form to tooth-implanting naturally surround and fastening, it is rooted among alveolar bone firmly, and not easily get loose displacement.In addition, retainer 2 top is the Rotary-table shape of side with tangent plane 7, can prevent artificial tooth from producing rotate by correspondence after installing artificial tooth, more reliable and more stable.
