Description

A kind of Dnetal implant component

Technical field

This utility model relates to oral cavity manual tooth planting, relates in particular to a kind of Dnetal implant component.

Background technology

Oral cavity implanting tooth is to repair at present a mouthful best method for inner teeth gear disappearance.Dental implant surgical of the prior art, normally plants tooth body by one and directly imbeds in advance dental bed, after above planting tooth body, install a retained abutment separation and that expose to dental bed surface, a corona is finally installed in this retained abutment again again, to realize the implantation of artificial tooth.

Visible, the composition of existing Dental Implant includes multiple members such as planting tooth body, retained abutment and corona.Because its structural design is unreasonable, it usually exists: it is various 1, to plant syndeton complexity between tooth body and retained abutment, and implant procedure is loaded down with trivial details, and also exists and connect defective tightness, easily causes impurity to enter in its joint gap impact fixing; 2, it plants the generally standing cylindricality of counting of tooth body, it with body bone tissue between while being connected steadiness poor; 3, by artificial tooth is directly installed in retained abutment, its denture upper jaw power is difficult to adjusted distribution, and periodontal trauma easily occurs, and its canine implant is loaded larger, plants tooth success rate lower, and service life is shorter; 4, Dental Implant is subject to the effect of alternating force in installing and using, and can easily occur looseningly, and this loosening can not again tightening can only again be planted, thereby increased the operations such as plantation again, caused significant wastage; 5, Dental Implant can not planted the sclerotin weakness such as tooth body tip after implantation, then adds that other plant the material of tooth steadiness to increase as bone grafting material, biotic factor etc., and often sclerotin is plentiful not, easily causes and plants tooth failure; 6, after device corona, through life-time service or improper use, retained abutment also can rupture, and corona is come off and can not re-use, and now, the residual tooth body of planting after fracture need be extracted to re-assembly, and so also equals to plant tooth failure; 7 and usually exist mechanical property and biocompatibility poor, and between tissue, also exist in conjunction with defective tightness reliably, easily produce looseningly, after long-time use, there will be repulsion with tissue, and affect the problems such as its service life.Therefore need badly its improvement.

Utility model content

The purpose of this utility model is to provide a kind of Dnetal implant component, this Dnetal implant component can be avoided the interference of alternating force preferably, structure is advantages of simple more, the tip that also other materials of planting tooth steadiness to increase such as bone grafting material, biotic factor can be introduced to Dental Implant, and there is certain repair function, and have good biocompatibility concurrently.

The purpose of this utility model is achieved in that

A kind of Dnetal implant component, is characterized in that: it forms by planting tooth body, retained abutment, extension spring and cushion pad; Described in being fixed on, described retained abutment plants the upper end of tooth body; The described tooth body of planting is made up of body and afterbody, and its body employing porous tantalum product, and its porosity is 60% ~ 70%; This body outer surface of planting tooth body is set to regular screw threads, and the inside of its afterbody is provided with groove; On sidewall in this groove, be provided with ridged annular projection; Described extension spring is arranged in this groove, and fixes by the ridged annular projection on its sidewall; Described tail end face of planting tooth body also horizontal distribution has the guiding gutter being communicated with described groove; The inside of this Dnetal implant component, is also provided with from the upper surface of described retained abutment vertically downward and the through hole communicating with described groove; In described retained abutment, cushion pad is set.

Through adopting the body of planting tooth body of porous tantalum product of above-mentioned porosity, can meet the mechanical property requirements of this Dnetal implant component in application, and through adopting porous tantalum structure, can also make bone grow into and the structure of growing in forming, thereby organically combine as a whole with body bone tissue, in greatly having improved biocompatibility, also well meet its mechanical property, improve service life and implanted comfort level, wherein stability and the anti-verticity of end structure after having increased artificial prosthesis and implanting.This porous tantalum product can adopt the preparations such as foam dipping method, die pressing.

Further, the above-mentioned tooth body of planting is cylinder, and this diameter of planting tooth body afterbody is short compared with the diameter of body.Further, above-mentioned body of planting tooth body and afterbody adopt welding or bonding connection as a whole.The tooth body of planting of this structure setting has been realized with alveolar bone and being firmly connected, and has the effects such as the sinking of further preventing.

Further, above-mentioned retained abutment is Rotary-table or cylinder, and this retained abutment and above-mentioned body of planting tooth body adopt welding or bonding connection as a whole.Which has realized simple and reliablely the two has been connected to an entirety.The retained abutment of this Rotary-table shape or cylindrical shape, can install cushion pad in order to Corresponding matching, and then again corona is installed on cushion pad, and has realized the implantation of artificial tooth.

The utlity model has following beneficial effect:

1, this utility model is simple in structure, it by plant the body of tooth body and retained abutment adopt welding or bonding connection as a whole, simplified the connection of the two, be convenient to produce, and overall good stress performance;

2, adopt extension spring one end is fixed on the alveolar bone of bottom, the other end is fixed on the groove of planting inside, tooth body lower end, and realize the alveolar bone close contact all the time of this structure and bottom, also realized and continue its overall structure to apply active force simultaneously, in use, if become flexible because of external force, extension spring makes it again keep close contact by elastic force, and then has ensured fixed effect;

3, in its structure, plant the body employing porous tantalum product of tooth body, well meet its mechanical property, also greatly increase its biocompatibility simultaneously, improved service life and implanted comfort level, increased stability and anti-verticity after this artificial prosthesis is implanted;

, can there is when fracture in retained abutment in 4, through hole its inside configuration setting, that communicate with groove, utilize the space in its through hole to imbed a stud, the maintenance platform of its fracture is repaired, with again by retained abutment with plant tooth body and connect as one;

5, by be provided with the through hole communicating with the groove of inside, lower end of planting tooth body in its structure, realize sclerotin weakness such as planting tooth body bottom has been introduced, has been evenly distributed on to other materials of planting tooth steadiness to increase such as bone grafting material, biotic factor, and increased the stability that this structure is connected with sclerotin, make implantation body and bony fusion faster, better;

6, its outer surface of planting tooth body body is also provided with regular screw threads, has further strengthened with the firm of alveolar bone and has been connected;

7, by add cushion pad between artificial tooth and retained abutment, scalable denture upper jaw power is distributed, and has avoided periodontal trauma, has alleviated the load of implant tooth, has improved the success rate of artificial growth, and has increased its service life;

The guiding gutter of the horizontal distribution 8, being communicated with through hole by increase at the bottom end face of planting tooth body, has greatly improved the broken last mobility that waits material of flesh and blood, has increased the bio-compatible that its structure arranges.
