Description
Technical field
This utility model relates to Medical oral cavity manual tooth planting's medical apparatus and instruments, relates in particular to one kind and plants dental structure.
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.
But, plant tooth body and in use can be subject to for a long time the effect of alternating force, particularly work as Dental Implant when mounted, if move past manyly to words lateral deviation, easily occur in a short time looseningly, and to plant the design of tooth body structure unreasonable due to existing, cause this becoming flexible can not again tighten at present, can only again plant, thereby increase the operations such as plantation again, cause significant wastage.And the tooth body of planting of the prior art exists certain defect on structure arranges, and causes its mechanical property and biocompatibility poor, after long-time use, there will be repulsion with tissue, and affect the problems such as its service life.
Utility model content
The purpose of this utility model is to provide one kind to plant dental structure, and this is planted dental structure and can closely be connected with alveolar bone planting tooth body in real time, can avoid preferably its interference that is subject to alternating force, simple in structure, intensity is higher, and has good biocompatibility concurrently.
The purpose of this utility model is achieved in that
Plant a dental structure, it is characterized in that: it forms by planting tooth body, retained abutment and extension spring; The described tooth body of planting adopts porous tantalum product, and its porosity is 60% ~ 70%; This is planted tooth body inside and is provided with the through hole running through up and down; The inner surface of tooth body of planting of this through hole middle and upper part is provided with regular screw threads, and the tooth body inside of planting of this through hole bottom is provided with extension spring; Described retained abutment bottom is threaded rod, and this threaded rod is connected with one end of described extension spring, and coordinates with described regular screw threads of planting the inner surface setting of tooth body.
The porous tantalum product of above-mentioned porosity, can meet this and plant tooth body in the mechanical property requirements of planting in dental structure, is closely connected reliably with alveolar bone to realize it.This porous tantalum product can adopt the preparations such as foam dipping method, die pressing.Through the discovery that studies for a long period of time: adopt the tooth physical ability of planting of porous tantalum product that bone is grown 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, having increased stability and anti-verticity after artificial prosthesis is implanted.
Further, the above-mentioned tooth body of planting is the cylinder being made up of cervical region, middle part and afterbody.
Further, above-mentionedly plant the cervical region of tooth body and the diameter at middle part is consistent, and the outer surface at middle part is that tooth form angle is the regular screw threads of 60 °; The diameter of its afterbody is narrow compared with cervical region or middle part.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.
The top of above-mentioned retained abutment is Rotary-table, and one-body molded with the threaded rod of above-mentioned retained abutment bottom.The Rotary-table on its top can be installed corona in order to Corresponding matching, and has realized the implantation of artificial tooth.
The utlity model has following beneficial effect:
1, plant tooth body and adopt regular screw threads to be connected with retained abutment, easily produce self-locking, good stress performance;
2, adopt the bottom that extension spring one end is fixed on to alveolar bone to continue that retained abutment is applied to elastic force, be fixed in the through hole of planting tooth body inside, guaranteed retained abutment all the time with plant tooth body close contact, itself apply the effect of power simultaneously by retained abutment to planting tooth body, make to plant the bottom close contact all the time of tooth body and alveolar bone; In use, if because external force makes to plant tooth body or retained abutment is loosening, extension spring makes it again keep close contact by elastic force, and then has guaranteed fixed effect;
3, plant tooth body itself and adopt porous tantalum product, well meet its mechanical property, also greatly increase the biocompatibility that this plants dental structure simultaneously, improved service life and implanted comfort level, increased stability and anti-verticity after this artificial prosthesis is implanted.

Fig. 2 is the structural representation of planting dental structure integrated connection described in Fig. 1.
The specific embodiment
Be below this utility model preferred embodiment, and be not intended to limit protection domain of the present utility model.
As shown in Fig. 1～2: plant dental structure for one kind, it forms by planting tooth body 1, retained abutment 2 and extension spring 4; It is planted tooth body 1 and adopts porous tantalum product, and its porosity is 60% ~ 70%; This is planted tooth body 1 inside and is provided with the through hole 3 running through up and down; The inner surface of tooth body 1 of planting of these through hole 3 middle and upper parts is provided with regular screw threads, and tooth body 1 inside of planting of these through hole 3 bottoms is provided with extension spring 4; Its retained abutment 2 bottoms are threaded rod 5, and this threaded rod 5 is connected with one end of extension spring 4, and coordinate with the regular screw threads of planting tooth body 1 inner surface setting; It plants the cylinder of tooth body 1 for being made up of cervical region 6, middle part 7 and afterbody 8; The cervical region 6 of planting tooth body 1 is consistent with the diameter at middle part 7, and the outer surface at middle part 7 is that tooth form angle is the regular screw threads of 60 °; The diameter of its afterbody 8 is narrow compared with cervical region 6 or middle part 7; The top of retained abutment 2 is Rotary-table, and adopts medical titanium alloy through one-body molded with the threaded rod 5 of its underpart; The Rotary-table Corresponding matching on the top of retained abutment 2 is installed corona, and then has realized the implantation of artificial tooth.
In clinical practice, extension spring 4 one end are fixed on to the bottom of alveolar bone, the other end is fixed on the threaded rod 5 of retained abutment 2 bottoms to continue that retained abutment 2 is applied to elastic force, be fixed in the through hole 3 of planting tooth body 1 inside, guaranteed retained abutment 2 all the time with plant tooth body 1 close contact, itself apply the effect of power simultaneously by retained abutment 2 to planting tooth body 1, make to plant the bottom close contact all the time of tooth body 1 and alveolar bone; If, because external force makes to plant tooth body 1 or retained abutment 2 is loosening, extension spring 4 makes it again keep close contact by elastic force, and then has guaranteed fixed effect when use.
