Description
Technical field
The porcelain the present invention relates to a kind of borate bonds, more particularly to a kind of Novel boron for improving titanium-porcelain bond strength
Hydrochlorate bonding porcelain and preparation method thereof.
Background technology
Metal-Ceramic prosthesis are a kind of important fixed denture reparations.Because it has stronger mechanical strength and wear-resistant
Performance, outstanding decay resistance and biocompatibility and outward appearance true to nature, stable color and luster and smooth surface, metal-roasting
Porcelain reparation is just being applied to more and more widely in dentures repai.Most stainless steels is used up till now from earliest noble metal,
NiCr and CoCr etc., the development that metal-Ceramic prosthesis experience nearly 60 years is quite ripe.But noble metal-Ceramic prosthesis are deposited
In price costly, it is unfavorable for its popularization；Conventional metals-Ceramic prosthesis, the such as biocompatibility of stainless steel and NiCr alloys
There is a problem of certain, Ni of generation2+, Cr3+With higher sensitization and pathogenic.
Titanium and its alloy have high wear-resisting and corrosion resistance, low density and modulus and outstanding biocompatibility and machine
Tool performance, is the first-selection of medical material, has been applied to such as joint prosthesis, internal strap, tooth-planting denture and artificial tooth
Repair etc..Although titanium or its alloy in Ceramic prosthesis have lot of advantages, titanium-porcelain bond strength far below conventional metals-
Porcelain bond strength, easily splits porcelain and collapses the phenomenon of porcelain in actual Ceramic prosthesis.The surface of titanium can form one layer 5 under room temperature
～10nm fine and close oxide layer, due to the property of titanium it is extremely active so that at high temperature (800 DEG C) are drastically thickened for this layer of oxide layer
And become loose, porous and cohesive force is poor, which results in the reduction of titanium-porcelain bond strength.
Improve titanium-porcelain bond strength method generally have surface coarsening process (CN102181816A and
CN102499773A), surface is modified and surface coated treatment (CN102808161A).Surface coarsening processes commonly sandblasting behaviour
Make, i.e., make the gas of certain pressure carry the alumina particle impact titanium or its alloy substrate of certain particle size, shape using sand-blasting machine
Into rough surface, to increase the mechanical interlock power of titanium and porcelain.Surface is modified refer to by titanium or its alloy be placed in acid, alkali,
In salt or organic solution, by reaction therewith and by the process in later stage reaching modified purpose.Surface coated treatment
It is to prepare one layer of nanometer or micron-sized coating on the surface of titanium or its alloy substrate using certain method to play prevention titanium
The effect of over oxidation, common technique has differential arc oxidation, sol-gal process and magnetron sputtering etc..
Except above-mentioned surface treatment, the porcelain that bonds is also to improve the important method that titanium-porcelain is combined.According to the difference of composition,
Can bonding porcelain be divided into silicate and borate-based.United States Patent (USP) (US5314334, US5228232 and US5176747) is proposed
Preparing silicate bonding porcelain in titanium alloy surface can effectively improve titanium-porcelain bond strength.Chinese patent (CN102745979B and
CN101664368B the formula of Silicate Binding porcelain) is also disclosed that.SiO in silicate bonding porcelain2Can be anti-at high temperature with Ti
Should, the disilicide layer Si of the more crisp oxygen-enriched titanium-containing layer α-Ti [O] of generation and Silicon-rich5Ti3(O), the more crisp material of this two-layer is easily induced
The generation of titanium-porcelain interface crackle and extend and ultimately result in the reduction of titanium-porcelain bond strength.Current is commercial borate-based viscous
Knot porcelain has Initial-Ti and TiKrom, wherein, in the case where blasting treatment is carried out, titanium-porcelain of Initial-Ti is combined by force
Spend still relatively low, only about 31MPa；And TiKrom contains poisonous Ba2+(referring to S.Zinelis etc., Bond strength and
interfacial characterization of eight low fusing porcelains to cp Ti.Dental
