Description
Technical field
The invention belongs to implant prostheses technical field, particularly to a kind of dental implant system that tooth implant and base station attachment structure are optimized design.
Background technology
Implant denture (implant-borneprothesis) is the class agomphosis dummy based on tooth implant support, maintenance, it is described as " the 3rd secondary tooth " of the mankind, there is removable partial denture and the incomparable advantage of fixed denture, become the focus of stomatology development.Implant prostheses is a complicated system engineering, and its clinical efficacy is subject to multifactor impact perhaps.The structural design of implant denture is one of factor affecting its clinical effectiveness, by optimizing of implantation body's structure is designed the mechanics transmission that can improve implantation body, increases the service life, it is ensured that success rate at a specified future date.
In the art, implantation body's threaded form is generally adopted single screw thread, special sclerotin is not easily obtained to the primary stability of implantation body；Hexagonal hole anti-rotational structure it is generally adopted inside common implantation body, in operation Implant process, implant the surface configuration of spanner destructible hexagonal hole, thus reducing the fiting effect of base station and implantation body, and hexagonal hole structure considerably increases the stress of implantation body and base station connecting screw, easily cause loosening or fractureing of center screw.Implantation body and the typically no successful feedback function in place of base station attachment structure, although also have and can realize individually this feedback, but owing to structure is complicated, add the difficulty of processing.
Summary of the invention
In order to overcome above-mentioned Problems existing, we design a kind of novel dental implant system.This implant system reasonable in design is simple, it is easy to processing, easy to use, has the advantages such as bonding strength height, anti-rotation, feedback in place.
The present invention adopts the following technical scheme that
Dental implant system, is connected by center screw including base station, center screw and implantation body, implantation body and base station, and the internal processing of described implantation body has inner circle taper hole, the bottom of inner circle taper hole to be provided with one section of three square hole；Described base station is provided with three cubes matched with tripartite's pore structure inside implantation body.
Described implant surface is provided with containing zinc active coating.Implant surface pattern is micropore shape oxide layer structure, pore arrangement uniform close, hole edge projection to the periphery；Implant surface element and atomic percent: 21.83%Ti, 72.77%O, 1.40%P, 3.15%Ca, 0.85%Zn, wherein Zn+Ca and P molar ratio is Zn+Ca:P=2.86:1.
Described implantation body's lower thread is coarse-pitch thread, and threaded form is isosceles trapezoid, and neck thread is fine thread, and pitch is 0.6mm-0.8mm.
The top of three described square holes is circular arc, and annular lock groove is arranged at the bottom of three square holes, and the bottom of annular lock groove is provided with one section of through hole, and through hole is female thread structure.
Described base station includes bullet foundation pile 11, wears gum portion 12, three cube 13 and snap close 14, bullet foundation pile is connected with corona, wear gum portion for bullet reciprocal with bullet foundation pile, the bottom wearing gum portion connects three cubes, three cubes be connected with snap close, between snap close and three cubes, cylinder is set.
Symmetrical two projections of described cylindrical outer surface.
Described base station is internally provided with stairstepping through hole.
Described center screw head is hexagonal cylindrical body in, and center screw lower end is provided with one section of cylinder matched with the through hole of base station, and center screw bottom thread matches with implantation body internal whorl.
Beneficial effects of the present invention:
Implantation body's form Design is optimized by the present invention, and process of surface treatment and threaded form and pitch design Dou Shi implantation body and be obtained in that good primary stability, union effects and rational stress distribution.Implantation body and base station attachment structure have employed three cube structures, can obtain the anti-rotation effect of high intensity, again can dispersive stress effectively, it is prevented that the loosening or fracture of center screw.The simple type snap close of base station lower end, i.e. symmetrical two spherical protuberances in base station lower cylindrical surface, play certain audition and sense of touch feedback effect, it is ensured that base station is completely in place when by base station with implantation body's assembling.Implant surface adopts micro-arc oxidation to process technique, makes containing zinc active coating, and surface forms microcellular structure and good hydrophilic, it is easy to form good synosteosis；Optimize the attachment structure devising implantation body and base station, it is ensured that formed and stablize and the connection of high intensity, thus improving the life and reliability of implant system.
