Abstract
The utility model discloses a kind of implanted artificial tooth.Described implanted artificial tooth is formed by planting root of the tooth 1, plantation base station 2 and screw 3; Described plantation base station 2 inserts described plantation root of the tooth 1 top, is fixed on described plantation root of the tooth 1 by described screw 3 by described plantation base station 2; Described plantation root of the tooth 1 top is provided with annular groove 4; Described plantation root of the tooth 1 distributes trapezoidal thread 6 and angular thread 5 from top to bottom successively.The implanted artificial tooth of this structure, improves bearing capacity, improves masticatory efficiency, increases Integrated implant face, strengthens the fusion with dental bed, improves the long-time stability of structure, substantially prolongs service life.
Description
Technical field
This utility model relates to a kind of implanted artificial tooth, particularly relates to that a kind of bearing capacity is strong, masticatory efficiency is high, Integrated implant face is large, long-time stability are high, the implanted artificial tooth of long service life.
Background technology
At present, tooth-planting system market being dropped into Clinical practice is hundreds of.On Integrated implant theoretical basis, raising is updated by aspects such as the improvement to the making of implanted denture designing, surgical technic, promote oral implantology development with ripe, become integrate oral and maxillofacial surgery, the clinical new branch of stomatology that prosthetic dentistry, periodontal, biomechanics, medical material, precision optical machinery add high-tech achievement in the subjects such as engineering.Success or failure and the treatment effect of implant operation mainly depend on implanted artificial tooth material, implant the implanted artificial tooth of surgery operating technology and correct design and precision manufactureing.
Utility model content
In view of the foregoing defects the prior art has, this utility model aims to provide that a kind of bearing capacity is strong, masticatory efficiency is high, Integrated implant face is large, long-time stability are high, the implanted artificial tooth of long service life.
To achieve these goals, this utility model by the following technical solutions: a kind of implanted artificial tooth, is made up of plantation root of the tooth, plantation base station and screw; Described plantation base station inserts described plantation root of the tooth top, is fixed on described plantation root of the tooth by described screw by described plantation base station; Described plantation root of the tooth top is provided with annular groove; Described plantation root of the tooth distributes trapezoidal thread and angular thread from top to bottom successively.
As the improvement to the technical program, described plantation root surface has carried out coarse process.
As the improvement to the technical program, the quantity of described annular groove is 1 to 3.
As the improvement to the technical program, the axial length of described trapezoidal thread and angular thread is than between 1.4 to 1.5.
As the improvement to the technical program, the thread form angle of described trapezoidal thread is between 89 ° to 136 °.
As the improvement to the technical program, the thread form angle of described angular thread is between 29 ° to 81 °.
As the improvement to the technical program, the external diameter of described plantation root of the tooth is 4.5mm or 5mm.
Compared with the prior art, this utility model is owing to have employed technique scheme, improve the bearing capacity of implanted artificial tooth, improve masticatory efficiency, increase Integrated implant face, strengthen the fusion of implanted artificial tooth and dental bed, improve the long-time stability of structure, substantially prolongs the service life of implanted artificial tooth.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model embodiment.
Fig. 2 is the assembling design sketch of this utility model embodiment.
In figure: a kind plant root of the tooth, 2 kinds plant base station, 3 screws, 4 annular grooves, 5 angular threads, 6 trapezoidal threads.
Detailed description of the invention
Below by embodiment, this utility model is specifically described; what be necessary to herein means out is that following examples are only for being further detailed this utility model; can not be interpreted as the restriction to this utility model protection domain, those skilled in the art can make some nonessential improvement and adjustment according to foregoing to this utility model.
Embodiment: a kind of implanted artificial tooth, as shown in Figure 1-2, implanted artificial tooth is formed by planting root of the tooth 1, plantation base station 2 and screw 3; Described plantation base station 2 inserts described plantation root of the tooth 1 top, is fixed on described plantation root of the tooth 1 by described screw 3 by described plantation base station 2; Described plantation root of the tooth 1 top is provided with annular groove 4; Described plantation root of the tooth 1 distributes trapezoidal thread 6 and angular thread 5 from top to bottom successively.
The material of implanted artificial tooth preferably has the metal material of better biocompatibility and mechanical strength, such as titanium or titanium alloy.In order to increase contact surface, coarse process has been carried out on described plantation root of the tooth 1 surface.
Annular groove 4 has increase contact surface, thus augmenting bone integrates the effect in face, promotes the fusion of implanted artificial tooth and dental bed, improves the long-time stability of structure.The quantity of annular groove 4 preferably 1 to 3, the present embodiment adopts 2.When the quantity of annular groove 4 is 2, the annular groove 4 on top apart from distance (being illustrated as M) the preferably 0.28mm of described plantation root of the tooth 1 upper surface, spacing (being illustrated as S) the preferably 0.8mm of 2 annular grooves 4.
Relative to angular thread 5, trapezoidal thread 6 intensity is higher, is arranged on plantation root of the tooth 1 top and contributes to improving the bulk strength of structure, strengthens its bearing capacity in use and masticatory efficiency.Angular thread has good self tapping, is conducive to screw-in when implanting.The setting of two kinds of helicitic textures has taken into account the long-time stability of operability and the structure implanted, and has better comprehensive effectiveness, contributes to the service life extending artificial tooth.Learn according to productive experiment, the axial length ratio of described trapezoidal thread 6 and angular thread 5 is preferred between 1.4 to 1.5, to obtain optimum combination property.The thread form angle of described trapezoidal thread 6 is preferably between 89 ° to 136 °, and the thread form angle of described angular thread 5 is preferably between 29 ° to 81 °.
According to the stock size of human body alveolar bone, preferred 4.5mm or 5mm of external diameter of described plantation root of the tooth 1.
