Description
Technical field
The utility model relates to tooth implantation technology fields.
Background technique
Traditional dental implant is the pure titanium or titanium alloy material of solid construction, and elasticity modulus, yield strength are much larger than
Bone tissue, the problem of easily causing stress shielding, and then the regeneration of bone tissue is influenced, and it is unfavorable for synosteosis, it is final to influence plantation
The stability and service life of body.The planting body of existing porous structure is manufactured using 3D printing, is influenced by machining accuracy
Easily there is manufacturing deficiency, occur the case where stress concentration at hole, the dental implant for eventually leading to porous structure is being planted
The mechanical strength at initial stage is not up to standard.
Utility model content
For disadvantage mentioned above, the utility model devises a kind of porous dental implant of degradable magnesium ion, by
Filling degradable layer in the hole of porous dental implant guarantees that it has enough so that planting body is solid construction in initial planting
Mechanical strength.After planting, biodegradable layer will voluntarily degrade, so that hole will be vacated, induction bone tissue is grown into, final to plant
Body and alveolus ostosis synosteosis.
A kind of porous dental implant of degradable magnesium ion, including the implant abutment printed by pure titanium with SLM technology,
There is porous structure, surface is equipped with spherical pore or thread groove, the spherical pore or thread groove filling in the implant abutment
There is biodegradable layer, the biodegradable layer is adhered to by magnesium granules transient melting to be formed.
Further, the spherical pore or thread groove on the implant abutment surface are connected to the porous structure, part or complete
Biodegradable layer is filled in portion's porous structure.
Further, the biodegradable layer positioned at implant abutment surface protrudes from spherical pore or thread groove.
The porous dental implant of degradable magnesium ion disclosed by the utility model, the biodegradable layer of surface inserting is by swashing
Light heating melts and realizes attachment, can cover the rough surface of the pure titanium implant foundation pile of SLM printing well, reduce SLM
The processing request of printing；The elasticity modulus of biodegradable layer, yield strength are close to bone tissue simultaneously, so that porous dental implant
The problem of stress shielding will not occur in initial planting；And the magnesium ion that biodegradable layer includes can promote cells grown, have
Conducive to the process for accelerating synosteosis.

Specific embodiment
It is carried out below with reference to technical effect of the embodiment and attached drawing to the design of the utility model, specific structure and generation
It clearly and completely describes, to be completely understood by the purpose of this utility model, feature and effect.Obviously, described embodiment
It is a part of the embodiment of the utility model, rather than whole embodiments, the embodiments of the present invention, those skilled in the art
Member's other embodiments obtained without creative efforts, belong to the range of the utility model protection.Separately
Outside, all connection/connection relationships being previously mentioned in text, not singly refer to that component directly connects, and referring to can be according to specific implementation feelings
Condition, by adding or reducing couple auxiliary, Lai Zucheng more preferably coupling structure.Each technical characteristic in the invention,
It can be with combination of interactions under the premise of not conflicting conflict.
Embodiment 1: as illustrated in fig. 1 and 2, a kind of porous dental implant of degradable magnesium ion is used pure by SLM technology
Titanium prints implant abutment 1, has porous structure in the implant abutment 1, and surface is equipped with spherical pore a2, planting body base
Stake 1 surface spherical pore a2 be connected to the porous structure, by way of machining to the internal screw thread of implant abutment 1 with
And hexagon link slot is finished, and fusing point is put into spherical pore a2 lower than the magnesium granules of pure titanium, using laser irradiation plus
Hot magnesium granules make its temperature moment be increased to fusing point, cause the magnesium of fusing that can be attached to rapidly on spherical pore a2 and penetrate into and fill out
Partially or fully porous structure is filled, the cooling processus aboralis of the biodegradable layer a3 of filling spherical pore a2 is for 1 surface of implant abutment.It is spherical
Hole a2 evenly distributed stephanoporate implant, which can guarantee to provide sufficient magnitude of interference, and guarantee planting body stress
Uniformly.
Embodiment 2: as shown in Figures 3 and 4, it is for spherical pore to be substituted for thread groove b2 with the distinctive points of embodiment 1.It fills out
It fills thread groove b2 and biodegradable layer b3 outstanding can serve as interim thread, installation is facilitated to fix.
SLM technology combines machining to shorten the process-cycle of dental implant with the mode of laser processing, ensure that its is whole
Body and structural strength.And this processing method can ignore SLM manufacturing tolerance, reduce cost.That inlays is degradable
Layer protrudes from surface, is uniformly distributed, and guarantees planting body uniform force, and surgical procedure is convenient, to ensure that planting body
Primary stability and structural strength.Initial planting high stability and good biocompatibility, biodegradable layer degradation release magnesium from
Son promotes the regeneration of osteocyte.Growing into for hole induction osteocyte is vacated simultaneously, finally ensure that the generation of synosteosis.To
Improve the success rate of implant operation.And the planting body scope of application of the utility model is wider.
The better embodiment of the utility model is illustrated above, but the invention be not limited to it is described
Embodiment, those skilled in the art can also make various equivalent changes without departing from the spirit of the present invention
Type or replacement, these equivalent variation or replacement are all included in the scope defined by the claims of the present application.
