Description
Technical field
The present invention relates to the composition of medical silicon nitride, manufacture, application, and in particular to a kind of photocuring 3D printing dentistry plantation
Body slurry and its preparation method and application.
Background technology
With the development of human society, the increase of aging population ratio, and war, traffic accident, athletic competition etc. are living
Unexpected injury caused by dynamic is also more and more, and which results in people's implants in vivo (artificial, elbow, knee joint, artificial femur
Head, utilization of cervical implants, Invasive lumbar fusion device, intervention support, pacemaker, artificial auditory ossicle, fracture of lumbar vertebra steel plate, screw fixture, tooth
Section's planting body etc.) demand increase.According to statistics, the annual whole world there are about 800,000 people and do joint prosthesis operation；Tooth-implanting is produced
Industry is also increased on world market with annual 20% speed.The wide application prospect of visible human body implant.
Conventional people's implants in vivo material has several major classes such as metal material, high-molecular organic material and ceramic material.
Titanium and its alloy because its good corrosion resistance, outstanding biocompatibility, low modulus of elasticity and excellent fatigue resistance into
For most widely used metal material in people's implants in vivo, but titanium alloy coefficient of friction is high, wears no resistance and often limits it
Application.Comparatively ideal high-molecular organic material is the superelevation average molecular weight northylen (UHMWPE) of excellent in abrasion resistance, relatively
Molecular mass about 3,000,000, its Volume erosion rate is only the 1/5~1/10 of high density polyethylene (HDPE) and nylon, and coefficient of friction is much small
In stainless steel.But its wear particle easily brings bone dissolution at a specified future date, and there are some researches show：When with gamma-rays to polyethylene
When transplant carries out disinfection, the polymer chain in radial energy cut-out ultra-high molecular weight polyethylene makes its wearability degradation.Phosphorus
Sour DFP ceramics, hydroxylapatite ceramic and calcium phosphate cement and bone, the inorganic composition of tooth are close, and its basis is hydroxyl
Apatite, belongs to biomaterial category.Research shows that the material has good compatibility and bone guided effect, but biomaterial
Deficiency is all there is in terms of intensity, toughness, plasticity.Played an important role for a long time in people's implants in vivo material
Aluminium oxide ceramics stable chemical performance, good biocompatibility, in biologically inert, its hardness is high, and anti-wear performance is good.But aluminum oxide
Ceramics category fragile material, its bending strength is only 380MPa, and fracture toughness only has 3.5MPam1/2, can go out in use
Existing brittle break and bone injury.And the fracture toughness of zirconium oxide is good, 15~30MPam is reached as high as1/2, but its Vickers hardness is only
There is 13Gpa, wearability is poor.
Silicon nitride ceramics due to high intensity, high rigidity, high abrasion resistance and good biological tolerance make its
Application in terms of the implantation in human body orthopaedics and joint receives much concern.Single silicon nitride ceramics under certain conditions by break-in,
Silicon nitride ceramics surface of friction pair can reach the clean degree of ultraphotic, and its friction factor and wear rate in water can become very little.From
From the point of view of tribology angle, under certain condition, its friction and wear behavior is quite outstanding for single silicon nitride ceramics.But single nitridation
Silicon ceramic sintering temperature is high, not easy-sintering and to there is aquation dangerous, and its performance must be generally improved by doping vario-property.
Silicon nitride is prepared into people's implants in vivo with other composition doping although having at present, is all to be confined to bone
On bone or articular prosthesis, silicon nitride is mixed with which composition can just overcome single silicon nitride ceramics as the scarce of people's implants in vivo
The correlative study that point can be suitable as dentistry implant again has no report.
The forming method of traditional silicon nitride ceramic material has dry-pressing formed, isostatic pressing, note solidification forming, is injected into
Type, these methods are required to preparation, sinter molding and the machinery in later stage of the mold design, silicon nitride powder or slurry of early stage
Processing, surface polishing.It can be prepared completely using conventional method for the simple people's implants in vivo of shape matching,
And for the preparation of the extremely complex people's implants in vivo of those shapes, particularly dentistry implant, using needed for conventional method
The early stage mold design and the machining operation in later stage wanted often lead to the extension of manufacturing cycle and the raising of production cost, very
Cause conventional method can not realize the manufacture of the product to due to unconventional complicated shape.
