Abstract
This utility model relates to a kind of compound and plants tooth nail.It is made up of implant (1), maintenance platform (2), erecting bed (3) and ring-type porous tantalum product (4); Described implant (1) upper end is fixedly connected with described maintenance platform (2); Described maintenance platform (2) upper end is fixedly connected with at least two described erecting beds (3); The body appearance of described implant (1) is also provided with annular recess (5), and is attached with one deck ring-type porous tantalum product (4) in annular recess (5); The afterbody (6) of described implant (1) is for bullet-headed.It is high that this utility model plants tooth efficiency, and biocompatibility is better.
Description
Technical field
This utility model relates to manual tooth planting, particularly relates to a kind of compound and plants tooth nail.
Background technology
Due to the reason such as pathological changes or wound, the needs of patients of oral cavity inner teeth gear disappearance carries out Artificial Intervention Dental Implant to repair.Conventional Dental Implant adopts the metal materials such as medical pure titanium alloy to make, after implanting osseous tissue can not implant infrastructure inner, its biocompatibility is poor, implantation is rear and body bone tissue easily produces repulsion, and service life is shorter, and that also very easily causes implantation body loosens problems such as even coming off.In addition, in conventional dental implant surgical, due to the deficiency of structural design, existing Dental Implant structure once can only realize the implantation of a tooth, and clinically when adjacent two adjacent teeths all need to implant, it is planted, and tooth number of times is more, the time is longer, implant efficiency not high, expense is larger.
Utility model content
The purpose of this utility model is to provide a kind of compound to plant tooth nail, and this compound plants tooth nail, and to plant tooth efficiency high, and biocompatibility is better.
The purpose of this utility model is achieved in that
Compound plants a tooth nail, it is characterized in that: it is made up of implant, maintenance platform, erecting bed and ring-type porous tantalum product; Described implant upper end is fixedly connected with described maintenance platform; Described maintenance platform upper end is fixedly connected with at least two described erecting beds; The body appearance of described implant is also provided with annular recess, and is attached with one deck ring-type porous tantalum product in annular recess; The afterbody of described implant is bullet-headed.
Specifically, above-mentioned erecting bed is preferably two, and symmetrical.According to the concrete condition of patient oral cavity domestic demand plantation adjacent teeth, on two erecting beds on maintenance platform, corresponding plantation installation two coronas, are applicable to the patient that two adjacent teeths all need to repair; And it is symmetrical, improve its structural mechanical property further.
Above-mentioned ring-type porous tantalum product, its porosity is 50% ~ 60%.This ring-type porous tantalum product can specifically adopt the preparations such as foam dipping method, die pressing.
As further optimization, above-mentioned implant, above-mentioned maintenance platform and above-mentioned erecting bed can through one-body molded be integral type structure, to simplify its structural design, be convenient to processing.
This utility model has following beneficial effect:
This utility model provides a kind of compound and plants tooth nail, it defines combined type porous adhesive layer by compound ring-type porous tantalum product, while meeting mechanical property requirements, achieve body bone tissue after implanting to grow into this loose structure, and structure of growing in inwardly filling and then being formed, it is one overall for achieving that artificial prosthesis and osseous tissue organically combine, considerably increase the biocompatibility of structure entirety, implant after stability and anti-rotation performance, improve service life and implant comfort level.Meanwhile, its structure optimization, once implants the reparation namely completing at least two teeth, decreases the number of times of planting tooth, saves operating time and expense, is suitable for the situation that two adjacent teeths all need to implant.
Accompanying drawing explanation
Fig. 1 for compound described in embodiment 1 plant tooth nail structural representation.
Fig. 2 for compound described in Fig. 1 plant tooth nail left view.
Fig. 3 for compound described in Fig. 1 plant tooth nail top view.
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 compound plant tooth nail, it is made up of implant 1, maintenance platform 2, erecting bed 3 and ring-type porous tantalum product 4, wherein, implant 1, maintenance platform 2 and erecting bed 3 through one-body molded be integral type structure; Its implant 1 upper end is fixedly connected with maintenance platform 2; Maintenance platform 2 upper end is fixedly connected with two symmetrical erecting beds 3; The body appearance of its implant 1 is provided with ring-type rectangular recess 5, and in ring-type rectangular recess 5, being attached with the ring-type porous tantalum product 4 that a layer porosity is 55% ~ 60%, this ring-type porous tantalum product 4 specifically can with reference to employing method preparation as described in patent 201110296515.7; The afterbody 6 of this implant 1 is bullet-headed.
This compound is planted tooth nail according to after the concrete condition kind implantation of patient oral cavity domestic demand plantation adjacent teeth, again respectively at corresponding plantation installation two coronas on erecting bed 3, namely achieve and namely implant two teeth by once implanting, be suitable for the patient that two adjacent teeths all need to repair.Its implant 1 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, implant after and body bone tissue embed closely, be connected firmly.
