Description
Technical field
The invention belongs to oral restoration therapeutic device technical field, and in particular to a kind of porous helicitic texture tooth implant is planted
Body.
Background technology
Absence of tooth turns into one of principal disease being detrimental to health, and WHO is by dental caries, cardiovascular disease and cancer
Being listed as the present age endangers one of three big diseases of human health, and dental caries are typical mouth diseases, most mouth disease
Absence of tooth can be caused.Due to improperly hygienic habit, the problems such as treating the understanding deficiency of mouth disease, the agomphosis per capita in China
Rate is far above the developed country such as American-European-Japanese.According to incompletely statistics, China mainland area agomphosis patient in 2012 has exceeded 300,000,000 people, nothing
Tooth patient there are about ten thousand people more than 2000；Epidemiological studies of the WHO to the elderly shows that suffering from oral disease the elderly is most,
With the arrival of China human mortality aging, this problem will become further serious.Absence of tooth can cause bradymassesis, increase to disappear
Change road burden even endangers periodontium health, can also lose the support to Maxillofacial soft tissue so as to be unfavorable for pronunciation and U.S.
See.Since nineteen sixty-five Sweden scientist professor Branemark takes the lead in releasing pure titanium implant, modern tooth-planting technology has
Rapid development, canine implant have become the important means for repairing absence of tooth.
The modulus of elasticity of planting body be influence canine implant success rate a key factor, too high modulus of elasticity meeting
Snap-in force is not uniformly transmitted to the bone tissue of planting body implant, or even cause stress shielding, make the office of planting body
Portion's stress is too high so as to causing graft failure.At present, conventional pure titanium is implanted into the elasticity of material relative to stainless steel, cobalt chrome molybdenum etc.
Modulus is greatly lowered, and is only about 110GPa, but still is far above the modulus of elasticity (cortex bone about 10GPa~25GPa) of skeleton,
Obvious stress shielding phenomenon can be still caused, so as to influence the long-time stability of planting body, or even causes planting body to come off or lose
Effect.
The content of the invention
The technical problems to be solved by the invention are to be directed to above-mentioned the deficiencies in the prior art, there is provided a kind of porous screw thread knot
Structure tooth implant implant.The body of the implant uses loose structure, effectively reduces the modulus of elasticity of implant and bone contact portion, from
And stress shielding phenomenon is significantly reduced or eliminates, implant caused by avoiding bone information loosens, and strengthens the combination between implant and bone
Stability, improve tooth implant implantation effect
In order to solve the above technical problems, the technical solution adopted by the present invention is：A kind of porous helicitic texture tooth implant is planted
Body, including body, screw thread is provided with body, offer sword groove on the screw thread, the center of middle and upper part in the body
Offer conical bottom screwed hole, it is characterised in that the body is porous body, and the porosity of the porous body is 5%~20%.
A kind of above-mentioned porous helicitic texture tooth implant implant, it is characterised in that the top of the body be connected with
Body is integrally formed to wear gum body, and the center for wearing gum body offers the through hole communicated with conical bottom screwed hole.
Above-mentioned a kind of porous helicitic texture tooth implant implant, it is characterised in that the sword groove is helical edges groove or straight
Sword groove.
Above-mentioned a kind of porous helicitic texture tooth implant implant, it is characterised in that have on the porous body multiple micro-
Hole, the aperture of the micropore is 200 μm~500 μm.
A kind of above-mentioned porous helicitic texture tooth implant implant, it is characterised in that the partial pore phase in multiple micropores
It is intercommunicated to form three-dimensional through hole, on the porous body cumulative volume of three-dimensional through hole for micropore on the porous body cumulative volume
30%~80%.
A kind of above-mentioned porous helicitic texture tooth implant implant, it is characterised in that the material of the tooth implant implant
For pure titanium, pure tantalum, Ti6Al4V titanium alloys, Ti6Al7Nb titanium alloys, Ti13Nb13Zr titanium alloys or Ti3Zr2Sn3Mo25Nb titaniums
Alloy.
Above-mentioned a kind of porous helicitic texture tooth implant implant, it is characterised in that the tooth implant implant is using gold
Category increasing material manufacturing method is prepared, and the metal increasing material manufacturing method is that manufacturing process or electron beam constituency are melted in selective laser
Melt manufacturing process.
The present invention has advantages below compared with prior art：
1st, the body design of tooth implant implant be loose structure by the present invention, the loose structure can effectively reduce implant and
The modulus of elasticity of bone contact portion, so as to significantly reduce or eliminate stress shielding phenomenon, implant pine caused by avoiding bone information
It is dynamic, the combination stability between implant and bone is enhanced, improves tooth implant implantation effect, and can be by adjusting porous body
Porosity adjust the density of the loose structure, intensity and modulus of elasticity, reach the biomethanics of implant and bone contact portion
The purpose of Performance Match, extend the useful life of tooth implant；In addition, the implant of loose structure occurs after elastic deformation
One longer stress plateau phase, buffering, damping and shock proof effect can be played to external active force, improves Dental implantion
The bearing capacity of body.
2nd, be advantageous to body fluid and nutriment there is three-dimensional through hole in body of the invention and passed in porous implant
It is defeated, promote the regeneration and reconstruction of bone tissue, accelerate agglutination, and the convenient bone tissue that accommodates is grown into the hole of implant,
Strengthen the implantation stability of tooth implant.
3rd, tooth implant implant of the invention melts manufacturing process or electron beam selective melting shaping side by selective laser
Method is prepared, the coarse structure of surface self-assembling formation micro-dimension, is advantageous to the adhesion, increment and differentiation of osteogenic tissue, induction
Bone tissue is grown into the porous hole of implant, makes to form biological fixation between implant and bone tissue, accelerates Integrated implant, without
Coarse structure or increase modified coating are prepared on implant surface by subsequent treatment, the process-cycle of implant is shortened, reduces
Production cost, improve safety in utilization.
4th, the present invention prepares tooth implant using selective laser fusing manufacturing process or electron beam selective melting manufacturing process
Implant, the porosity of implant can be accurately controlled, improve the precision of implant, and customization is prepared according to personal cavity skeleton character
The implant of change, implant and the matching of human body are improved, reduce the risk of dental implant.
Technical scheme is described in further detail below by drawings and examples.
