Description
Technical field
This utility model relates to Medical oral cavity manual tooth planting's medical apparatus and instruments, and dental structure is planted in the combination that relates in particular to a kind of Dental Implant.
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.On structure arranges, there is certain defect in the tooth body of planting of the prior art, cause it to be combined defective tightness with human body alveolar bone reliable, easily produce the problems such as loosening, and its mechanical property and biocompatibility are also poor, after long-time use, there will be repulsion with tissue, and affect the problems such as its service life.In addition, existing planting in dental structure, its retained abutment usually adopts single being threaded with planting between tooth body, and after adopting this structure to connect, the support force that its retained abutment that exposes to dental bed surface is subject to is in the horizontal direction lower, easily suffer the effect of horizontal lateral force and rupture, its reliability is lower.
Utility model content
The purpose of this utility model is to provide a kind of combination of Dental Implant to plant dental structure, the combination of this Dental Implant is planted dental structure and can be in real time will be planted tooth body with alveolar bone, be closely connected with retained abutment, can avoid preferably it to be subject to the interference of alternating force, simple in structure, intensity is higher, and has good biocompatibility concurrently.
The purpose of this utility model is achieved in that
A dental structure is planted in the combination of Dental Implant, it is characterized in that: it forms by planting tooth body, retained abutment, maintenance sleeve and extension spring; The described tooth body inside of planting 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 top of planting tooth body is also provided with the groove being communicated with described through hole, and in this groove, Corresponding matching is installed described maintenance sleeve; Described maintenance sleeve inner has a perforation running through up and down; Described retained abutment bottom is threaded rod, this threaded rod through the perforation in described maintenance sleeve after, plant the regular screw threads that the inner surface of tooth body arranges and coordinate with described, and the bottom of this threaded rod and one end of described extension spring are connected; This plants tooth body is the cylinder being made up of cervical region, middle part and afterbody, and its cervical region and afterbody all adopt porous tantalum product, and its porosity is 60% ~ 70%.
Adopt the cervical region of planting tooth body and the afterbody of the porous tantalum product of above-mentioned porosity, can meet it in the mechanical property requirements of planting in dental structure, be 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: the cervical region of planting tooth body and the afterbody that adopt porous tantalum product, can 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, having increased stability and anti-verticity after artificial prosthesis is implanted.
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 is fixed on after maintenance sleeve, can outside this maintenance sleeve, Corresponding matching be installed by corona, thereby realize the firm implantation of artificial tooth.
Further, above-mentioned cervical region and afterbody of planting tooth body, realizes and being fixedly connected with of above-mentioned middle part of planting tooth body through bonding or welding respectively.Its connected mode is solid and reliable.
Above-mentioned maintenance sleeve is torus, and the diameter of the perforation on its body top is greater than the diameter of its body underpunch.By the setting of this structure, the retained abutment top that can be further Rotary-table by its structure is fixedly limited in this maintenance sleeve, thereby has ensured the reliability of the two connection.
The utlity model has following beneficial effect:
1, 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, ensured 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 ensured fixed effect;
2, as cervical region and the afterbody of planting the non-stress position in tooth body structure, all adopt porous tantalum product, well meet and ensured its mechanical property, also greatly increased the biocompatibility that this plants dental structure entirety simultaneously, improve service life and implanted comfort level, having increased stability and anti-verticity after this artificial prosthesis is implanted;
3, plant tooth body and adopt regular screw threads to be connected with retained abutment, easily produce self-locking, good stress performance;
4, by groove being set at the top of planting tooth body, and Corresponding matching is installed maintenance sleeve in this groove, afterwards by the threaded rod of retained abutment bottom through after this maintenance sleeve again with plant tooth body and be connected, thereby strengthen the retained abutment support force being subject in the horizontal direction, suffered the effect of horizontal lateral force and the probability that ruptures and greatly reduce it.
