Abstract
The invention discloses an artificial tooth root component which comprises an implant 1, a foundation pile 2 and a set screw 3, wherein the implant 1 and the foundation pile 2 are connected together through the set screw 3; and a concave arc surface is formed between the upper end surface 5 of the implant 1 and the maximum diameter part 6 of the foundation pile 2. The artificial tooth root component with the structure has the advantages that the osteocyte initiation growth speed is higher, the postoperative healing effect is better, the recovery cycle of a patient is shortened, the connection tightness between an artificial tooth root and an artificial alveolar bone is higher, the looseness and the transposition of the artificial tooth root are avoided to a large extent, and the operative success rate is improved greatly, so that the implantation effect is improved effectively.
Description
Technical field
The present invention relates to a kind of artificial tooth root component, particularly relate to a kind ofly start that growth is fast, healing effect is good, the restore cycle is short, tightness is high, the displacement that not easily gets loose, success rate of operation are high, plant the good artificial tooth root component of effect.
Background technology
Implantation of tooth is as a kind of medical skill means for the treatment of human body anodontia or injury of teeth, and the effect good because of it is widely applied clinically.Artificial tooth root is parts basic and the most important in implantation of tooth, and it is rooted in human body alveolar bone, instead of nature root of the tooth and realizes its masticatory function.Artificial tooth root feels comfortable, similar dermal tooth, and the insoluble difficulty of many conventional artificial teeth repairs clinical case can obtain satisfied curative effect by plantation artificial tooth root.
But in clinical practice, structurally still there are some problems in existing artificial tooth root, osteocyte is easily caused to start poor growth, patient recovery times is longer, artificial tooth root is connected tightness deficiency with between human body alveolar bone after implanting, easily get loose displacement etc., and cause success rate of operation not high, planting effect is not ideal enough.
Artificial tooth root generally comprises the parts such as implant, foundation pile, hold-down screw, implant and foundation pile has hole usually, is convenient to hold-down screw and both is affixed to together.
Summary of the invention
In view of the foregoing defects the prior art has, the present invention aim to provide a kind ofly start that growth is fast, healing effect is good, the restore cycle is short, tightness is high, the displacement that not easily gets loose, success rate of operation are high, plant the good artificial tooth root component of effect.
To achieve these goals, the present invention is by the following technical solutions: a kind of artificial tooth root component, be made up of implant, foundation pile and hold-down screw, described implant and foundation pile are linked together by described hold-down screw, concaved circular cambered surface in being formed between described implant upper surface and described foundation pile maximum gauge place.
As the improvement to the technical program, the difference of described implant upper end surface external diameter and internal diameter is more than or equal to 0.4mm, is less than or equal to 0.5mm.
As the improvement to the technical program, the external diameter of described implant is 4.5mm or 5mm.
As the improvement to the technical program, the length of described implant is 12mm.
As the improvement to the technical program, the length of described artificial tooth root component is 18mm.
As the improvement to the technical program, the outer surface of described implant is with angular thread.
As the improvement to the technical program, described implant upper surface is provided with blind hole, and described blind via bottom is connected with screw; Described foundation pile is provided with through hole; Described foundation pile is vertically placed in the blind hole of described implant upper surface; Described hold-down screw by the through hole on described foundation pile, and matches with the screw on described implant.
Compared with the prior art, the present invention is owing to have employed technique scheme, osteocyte is made to start growth faster, postoperation recovery better effects if, patient's restore cycle shortens, and it is higher that artificial tooth root and human body alveolar bone are connected tightness, largely avoid the displacement that gets loose of artificial tooth root, substantially increase success rate of operation, make plantation effect obtain effective lifting.
Accompanying drawing explanation
Fig. 1 is the structural representation of the embodiment of the present invention.
In figure: 1 implant, 2 foundation piles, 3 hold-down screws, 4 healing districts, 5 upper surfaces, 6 maximum gauge places.
Detailed description of the invention
Below by embodiment, the present invention is specifically described; what be necessary to herein means out is that following examples are only for being further detailed the present invention; can not be interpreted as limiting the scope of the invention, those skilled in the art can make some nonessential improvement and adjustment according to foregoing to the present invention.
Embodiment: a kind of artificial tooth root component, as shown in Figure 1, artificial tooth root component is made up of implant 1, foundation pile 2 and hold-down screw 3; Described implant 1 and foundation pile 2 are linked together by described hold-down screw 3; Concaved circular cambered surface in being formed between described implant 1 upper surface 5 and described foundation pile 2 maximum gauge place 6.
Concaved circular cambered surface in being formed between implant 1 upper surface 5 and foundation pile 2 maximum gauge place 6, such structure makes to define an annular healing district 4 between foundation pile 2 outer surface and implant 1 upper surface.After artificial tooth root has been implanted, due to the existence in district 4 of healing, human bone cell can be rapidly to healing district 4 growth inside, until filled.Relative to traditional artificial tooth root, such structural priming bone tissue growth is obviously accelerated, and the restore cycle shortens greatly.And because bone cell growth fills the healing district of annular, it naturally form the encirclement of artificial tooth root and fastening, and make artificial tooth root be rooted in firmly among alveolar bone, not easily get loose displacement.Meanwhile, such mode of healing makes healing effect obviously strengthen, and artificial tooth root and human body alveolar bone more become to combining together, uses more freely comfortable.This series of advantage, make the plantation success rate of the artificial tooth root of this structure apparently higher than traditional structure, result of use after surgery also strengthens further, and patient chews more reliably freely.
According to a series of clinical trial, the difference of described implant 1 upper end surface external diameter and internal diameter is more than or equal to 0.4mm, when being less than or equal to 0.5mm, sclerotin grows into effect better (as shown in Figure 1, L is the difference of described implant 1 upper end surface external diameter and internal diameter).
According to the stock size of human body alveolar bone, preferred 4.5mm or 5mm of described implant 1 outside diameter d.For labial teeth, usually select 4.5mm; For backteeth, usually select 5mm.
Learn according to clinical experience, the preferred 12mm of length of described implant 1; The preferred 18mm of length of described artificial tooth root component.
For the ease of implanting, simplifying the operation, the outer surface of described implant 1 is with angular thread.This is because angular thread is comparatively sharp, have self tapping, incision and implantation synchronously complete.According to structural strength test, the thread form angle of angular thread, preferably greater than or equal to 30 °, is less than or equal to 80 °.
Implant 1 is connected by hold-down screw 3 with foundation pile 2, and the present embodiment is taked as under type: as described in implant 1 upper surface be provided with blind hole, described blind via bottom is connected with screw; Described foundation pile 2 is provided with through hole; Described foundation pile 2 is vertically placed in the blind hole of described implant 1 upper surface; Described hold-down screw 3 by the through hole on described foundation pile 2, and matches with the screw on described implant 1.
