Description
Technical field
The present invention relates to tooth implantation technology fields.
Background technology
Existing dental implant mostly uses greatly pure titanium or titanium alloy manufacture, and mostly solid construction.Its elasticity modulus, surrender
Intensity is much larger than bone tissue, the case where stress shielding easily occurs.For stress shielding the problem of, it is thus proposed that 3D printing system
The method for making porous dental implant.The knockdown design of existing dental implant be dental implant is divided into axially along multistage into
Row manufacture installation.
The pure titanium of existing solid construction or the dental implant of titanium alloy material, elasticity modulus, yield strength are much larger than
Bone tissue, the problem of easily causing stress shielding.To influence the regeneration of bone tissue, it is unfavorable for synosteosis, it is final to influence plantation
The stability and service life of body.Existing planting body deforms in use fracture when then need by sudden and violent
The mode that power is removed extracts dental implant, and operation is complicated and can cause larger damage.It is existing that stress is eliminated by porous structure
The method of shielding can cause the mechanical strength of the dental implant of porous structure not up to standard, and porous structure sacrifices planting body
Surface area size, to affect the process of synosteosis, while the fatigue life of this design is not high.
Invention content
For disadvantage mentioned above, the present invention devises a kind of dental implant containing polyether-ether-ketone interlayer, by increasing polyethers

External screw thread.
Further, the end face that the outer foundation pile is contacted with interior foundation pile is additionally provided with several mounting holes, and the mounting hole is located at
At lateral wall and angles is waited to be distributed.
The present invention also discloses a kind of manufacturing methods of the dental implant containing polyether-ether-ketone interlayer comprising step
Suddenly：
1) outer foundation pile and interior foundation pile are produced by the method that SLM technologies or machining or both combine；
2) polyether-ether-ketone resin that would be heated to molten condition is filled among the blind hole of external foundation pile；
3) after waiting for polyether-ether-ketone resin solidification, internal thread hole is drilled through out by mach mode；
4) interior foundation pile is grouped together with the outer foundation pile for being combined with polyether-ether-ketone resin.
Dental implant disclosed by the invention containing polyether-ether-ketone interlayer is reduced by increasing polyether-ether-ketone resin interlayer
The elasticity modulus of dental implant entirety, while indirectly increasing the fatigue life of dental implant.Polyether-ether-ketone resin simultaneously
Interlayer can effectively buffer the stress that dental implant is subject to, to protect the safety of alveolar bone.Pass through polyethers ether
The design of ketone resin interlayer not only ensure that the generation of synosteosis, while ensure that the intensity of planting body, and reduce Dental implantion
The difficulty of body manufacture installation.Dismounting replacement is carried out when multi-layer structure design can facilitate Dental implantion to damage, and reduces damage, especially
For center screw, often there is a situation where fail for it.Multi-layer structure design is conducive to the reuse of intact parts, section simultaneously
Cost is saved.Manufacturing method proposed by the present invention is affected simple, saves production cost.
