Description
Technical field
The utility model relates to a kind of artificial tooth, particularly relates to a kind of self-locking artificial tooth.
Background technology
Implant tooth is to treat the common treatment means of agomphosis at present, and it mainly will have bio-compatible
Property metal artificial root implant in the alveolar bone at agomphosis, by the tight collection of artificial tooth root and alveolar bone
Close, using artificial tooth root as pedestal replacement teeth mould.Owing to grinding off neighbouring tooth unlike stationarity artificial tooth
Tooth, thus there is not the damage of adjacent teeth, there is no secondary decayed tooth factor yet, be therefore ratio
The more stable method of stationarity artificial tooth.People lack many teeth and in the case of use removable denture, meeting
To periodontium (gum) force, thus can there is sense of discomfort in gum, and due to the size of artificial tooth, makes
Obtain intraoral foreign body sensation serious, but owing to tooth-implanting and tooth have essentially identical configuration, thus complete
Entirely will not feel pain and the foreign body sensation of gum, thus the quality of life of patients can be improved and bring satisfied
Sense.
But traditional dental implant all selects screw thread implantation, implant is the metal parts of entity,
With natural root of the tooth no matter in internal structure or form and suffer from very big difference, particularly overall
Hardness strength etc. are just the same, and the alveolar bone adaptability of patient will be caused tremendous influence by this.Screw-type
Surrounding socket bone tissue can be caused huge extruding force by implantation, easily produces stress concentration phenomenon, and table
Face is comparatively smooth, is unfavorable for the quick apposition growth of osteocyte, can cause withering of alveolar bone when serious
Contracting.Although and the screw-in of screw can play certain fastening effect, but tooth also can be damaged further
Groove bone.Additionally, existing canine implant mostly there is also plantation after be connected between artificial tooth not consolidate,
Easy loose or dislocation, anti-knob ability, poor with the connectivity of body bone tissue and biocompatibility etc..

Detailed description of the invention
Below in conjunction with specific embodiment, the utility model is more specifically described in detail.
Embodiment
As shown in Figures 1 to 6.The utility model discloses a kind of self-locking artificial tooth, including the plantation of artificial tooth
Body 1 and installation threaded rod 2 within it；Described planting body 1 is a tube structure, and its inside diameter is from upper
Tapering under to, the big up and small down inverted cone form of inner section (uses selective laser melt-forming
Technique, is the form inside contracting by Design of Screw Thread, thus forms the turbination reducing downwards.), and inner circumferential
Wall is female thread structure 6, and multiple bulge-structure 4 is distributed on the wall of outer wall；Under tube structure
Portion offers, along its axial direction, the thin seam 3 that four to six otch are formed, and carefully seam 3 is by the bottom of tube structure
Cut into four to six flap 5 that can radially extend expansion；Inverted cone form can make plantation 1 body without relatively
Can plant under big external force effect in the kind plant hole pre-setting into alveolar bone.
The described top of planting body 1 and the outer rim of low side are equipped with chamfering structure, and stress can be avoided to concentrate,
It is beneficial to fixing plantation.
Described threaded rod 2 is upper inferior radius cylindrical structure, and middle part is solid construction, and its bottom has
The external thread structure matching with the internal thread of tube structure.
The wall thickness of this tube structure is from top to bottom gradually increased；The rounding cone angle of this tube structure inner section
Be 4 °～5 ° (or 3.5 ° or 4.5 °), the reversed cone angle of outer cross section be 1 °～3 ° (or
2.5°)。
The length of described thin seam 3 is more than 1/2nd of tube structure axial length.When threaded rod 2 from
Upper and under when being screwed in tube structure, the flap 5 of tube structure bottom is under the squeezing action of threaded rod 2
Radial outward expansion expands, and makes the overall outline of planting body 1 be up-small and down-big positive pyramidal structure；Described
The out conductor inclination angle of positive pyramidal structure is 1 °～2 ° (or 1.5 °).The top of tube structure due to
Without thin seam, therefore keep reset condition without deformation.
Described bulge-structure 4 rule or be randomly distributed on the wall of tube structure outer wall.
Described bulge-structure 4 is protruding spherical structure, honeycomb structure, coral structures or eight rib body structures
In any one, or combinations thereof.
The end of described threaded rod 2 offers internal thread installing hole 23, for later stage plantation base station (outward
The artificial tooth body in portion) connect.
The wall of described threaded rod 2 end outer perimeter wall is symmetrical eight-sided formation.
Described eight-sided formation structure includes four symmetrical facets 21 and big plane 22；Facet
21 is interlaced with big plane 22；Big plane 22 is the installation base station of outside artificial tooth body, facet 21
It is the clamping face being for rotary screwing thread bar 2.
The material of described planting body 1 and threaded rod 2 is titanium alloy material.
When planting body 1 implants (not shown) in alveolar bone, due to the inverted cone structure of planting body 1,
This process only need to somewhat exert oneself just can be pressed in alveolar bone, it is to avoid conventional screw formula needs high-torque
Shortcoming.In the internal thread being threaded into planting body 1 of threaded rod 2, with the screw-in of threaded rod 2, plant
Implant top keeps constant, but bottom starts gradually outwards to expand, and simultaneously thin seam 3 starts to become big.Plantation
After end, planting body 1 lower expansion, top is constant, is formed as positive pyramidal structure cumulative downwards, its
Bevel angle is 2 °.The screw-in of threaded rod 2 makes planting body 1 internal thread become upper inferior radius form, with
Threaded rod 2 just mates completely.Now the lower surface of planting body 1 is concordant with threaded rod 2 lower surface, spiral shell
Chain-wales 22-1 below the big plane 22 of rasp bar 2 exceeds planting body 1 upper surface, is used for subsequent installation base station
And corona.
After plantation completes, planting body 1 is under the screw-in of threaded rod 2, and the bottom of planting body 1 is squeezed
Expand, the normal cone structure of formation so that planting body 1 is firmly fixed in alveolar bone, and planting body
The bulge-structure 4 on surface under the effect of expansive force in embedded indent bone, strengthen further planting body with
The connection of alveolar bone, its random or regular distribution bulge-structure 4 effectively hinders the rotation of planting body simultaneously
Turn, thus substantially increase the success rate of planting body.
As described above, just can preferably realize the utility model.
Embodiment of the present utility model is simultaneously not restricted to the described embodiments, and other are any without departing from this reality
With the change made under novel Spirit Essence and principle, modification, replacement, combination, simplify, all should be
The substitute mode of equivalence, is included within protection domain of the present utility model.
