Technical field
This utility model relates to canine implant, particularly relates to a kind of Dental Implant structure.
Background technology
At present, the artificial Dental Implant that adopts repairs oral cavity inner teeth gear disappearance, and can obtain the repairing effect quite similar with natural teeth function, structure and aesthetic, this technology has become the first-selected repair mode of more and more agomphosis patient.But in clinical practice, still there are some drawbacks not yet overcome in this technology, such as Dental Implant self tapping is poor, implant procedure is complicated; Defective tightness is connected, easy loose or dislocation with body bone tissue; Mechanical property and biocompatibility poor; When implanting neutralization use, anti-alternating force poor performance, easily occur loosening and causing increasing the operations such as plantation again, cause significant wastage etc., these technical problems directly affects the clinical application effect of canine implant.
Utility model content
For the above-mentioned defect existed, this utility model aims to provide a kind of Dental Implant structure, and this Dental Implant structure self tapping is good, it is efficient and convenient to implant, mechanical strength is high, stress performance good, can avoid the interference of alternating force and realize compact siro spinning technology, stablize maintenance.
To achieve these goals, this utility model is by the following technical solutions:
A kind of Dental Implant structure, is characterized in that: it is made up of implantation piece, retention means and extension spring; Described implantation piece adopts porous tantalum product, and its porosity is 60% ~ 70%; This implantation piece inside is provided with the through hole run through up and down; This through-hole inner surface is provided with regular screw threads, and in this through hole, bottom is placed with extension spring; The bottom of described retention means is threaded rod, and this threaded rod is connected with one end noose of described extension spring, and with the regular screw threads corresponding matching of described through-hole inner surface; In the middle part of described implantation piece, appearance is with trapezoidal thread or rectangular thread, and lower external is with angular thread.
The head of above-mentioned retention means is cuboid, and one-body molded with the threaded rod of its underpart.By the head of this rectangular-shaped retention means and corona corresponding matching in application, while achieving artificial tooth implantation, further increase anti-axial-rotation.
The thread form angle of the trapezoidal thread in the middle part of above-mentioned implantation piece is more than or equal to 90 °, is less than or equal to 135 °.
The thread form angle of above-mentioned implantation piece bottom angular thread is more than or equal to 30 °, is less than or equal to 80 °.
The axial length ratio of the trapezoidal thread on above-mentioned implantation piece and angular thread is more than or equal to 1.4, is less than or equal to 1.5.
Compared with the prior art, this utility model is owing to have employed technique scheme, and its overall structure, by being threaded, easily produces self-locking, good stress performance, and simplifies the structure; Implantation piece itself adopts porous tantalum product, well meets its mechanical property, also greatly increases biocompatibility simultaneously, improves service life and implants comfort level, adds the stability after the implantation of this artificial prosthesis and anti-rotation performance; Its underpart angular thread improves its self tapping, make implantation process more efficient and convenient, the trapezoidal thread in the middle part of it or rectangular thread improve the mechanical strength of structure entirety, improve stress performance, substantially increase the success rate of plantation, effectively improve clinical application effect; By the setting of through hole, other materials of planting tooth steadiness with increase such as bone grafting material, biotic factor are convenient to introduce, be evenly distributed on the sclerotin weakness such as implantation piece bottom, and add the stability that this structure is connected with sclerotin, make itself and bony fusion faster, better; In addition, adopt and extension spring one end is fixed on the alveolar bone of bottom, other end noose is connected on threaded rod, and achieve the alveolar bone close contact all the time of itself and bottom, also achieve simultaneously and continue to apply active force, to resist the effect of alternating force in real time to its overall structure, in use, if loosened because of external force, then extension spring makes it again keep close contact by elastic force, and then ensure that fixed effect.

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: as shown in Figure 1-2, a kind of Dental Implant structure, it is made up of implantation piece 1, retention means 2 and extension spring 8; Its implantation piece 1 adopts porous tantalum product, and its porosity is 60% ~ 70%, and this porous tantalum product specifically can adopt method preparation as described in patent 201110296515.7; This implantation piece 1 inside is provided with the through hole 3 run through up and down, and through hole 3 inner surface is provided with regular screw threads, and in this through hole 3, bottom is placed with extension spring 8; The bottom of its retention means 2 is threaded rod 4, and this threaded rod 4 is connected with one end noose of extension spring 8, and with the regular screw threads corresponding matching of through hole 3 inner surface; In the middle part of its implantation piece 1, appearance is the trapezoidal thread 5 of 95 ° with thread form angle, and lower external is the angular thread 6 of 60 ° with thread form angle, and the axial length ratio of this trapezoidal thread 5 and angular thread 6 equals 1.4; The head 7 of its retention means 2 is cuboid, and adopts medical titanium alloy one-body molded with the threaded rod 4 of its underpart, and by the head 7 of this rectangular-shaped retention means 2 and corona corresponding matching, namely achieves artificial tooth and implant.
Trapezoidal thread and rectangular thread have the feature of high strength, are arranged on bulk strength implantation piece 1 contributing to improve structure, strengthen its stress performance in use; Its angular thread has good self tapping, is conducive to screw-in when implanting, and simultaneously because its self-locking property is good, can improve the stability after implantation, make retention effect better.Arranging of two kinds of helicitic textures can be learnt from other's strong points to offset one's weaknesses, and makes implantation process conveniently ensure good mechanical property simultaneously, reaches optimum implantation effect, improves and be implanted to power, improve postoperative effective utilization.In addition, in clinical practice, extension spring 8 one end is fixed on the bottom of alveolar bone, other end noose is connected on threaded rod 4 to continue to apply elastic force to retention means 2, ensure that retention means 2 all the time with implantation piece 1 close contact, simultaneously to the effect of the overall applying power of its structure, make the bottom close contact all the time of itself and alveolar bone; If because external force makes structure, entirety loosens during use, then extension spring 8 makes it again keep close contact by elastic force, and then ensure that fixed effect.
