Abstract
The invention discloses a submicron zirconium oxide base dental material. The dental material comprises submicron Al2O3 and submicron ZrO2 powder; the composition formula thereof is xZrO2-yAl2O3, wherein x plus y is 100 vol%; the content of the submicron Al2O3 is 0-15 vol% of the total content; the average particle size of the ZrO2 powder is 0.3-0.5 microns; the specific surface area is 100-350 nm; the purity is 99.99%; the content of the submicron Al2O3 is 2.5 vol%, 5 vol%, 7.5 vol%, 10 vol% and 15 vol% of the total content. The material provided by the invention has good synthetic performances such as strength, roughness and wear resistance; the color opacifying characteristics thereof is similar to that of the enamel, so that the tooth aesthetics requirements can be satisfied largely; the submicron zirconium oxide base dental material is an ideal tooth material; high-performance submicron zirconium oxide base teeth have no poison and harm to human bodies, and have good compatibility.
Description
Technical field
The present invention relates to bioceramic material field, relate in particular to a kind of sub-micron zirconium oxide base dental material that is applied to tooth-planting and Oral Repair.
Background technology
The absence of tooth patient that China causes because of dental caries, periodontitis and injury of teeth reaches 1/5th to 1/3rd of total population.Therefore, accelerate the exploitation of dental prosthetic material and goods, remove millions upon millions of patients' misery, reduce medical expense burden, very important beyond doubt, be also the call of social development.Dental material has special performance requirement, not only requires suitable intensity, hardness, toughness and wearability, also should have and reproduce the function that nature creamy white is adjusted.At present, though porcelain-fused-to-metal dummy comparatively conventional in domestic Oral Repair can solve strength problem, its complex process, metal bottom tire has reduced the penetrance of porcelain to light, not only affect the aesthetic of dummy, but also may cause anaphylaxis to human body; Also excessive and bad with melts combine because of the fragility of porcelain body, often occur collapsing porcelain and failure has had a strong impact on clinical long-term effect.Along with improving constantly of people's esthetic requirement, the extremely patient's favor with the performance attractive in appearance of its uniqueness and good biocompatibility of all-ceramic crown bridge dummy, full porcelain reparation also becomes one of Main Trends of The Development of current oral cavity fixed and repaired.But existing full ceramic material still exists the defects such as insufficient strength, processing technique complexity and toughness are lower, also do not reach the requirement of clinical wide model application completely, the intensity and the toughness that how to improve full ceramic material have been the emphasis of research.The full ceramic material of novel dental of synthesizing high-strength, high tenacity, after realization expands to the range of application of full porcelain dummy under existing dental procedure condition, corona, bridge and dowel crown etc. are repaired the target in field, reduce porcelain powder and clinical processing cost, full porcelain recovery technique can be really applied to clinical, improve the quality of mouth mending material, promote the utilization of full porcelain dummy and popularize significant.
Summary of the invention
The object of the present invention is to provide a kind of sub-micron zirconium oxide base dental material, it has human body nonhazardous, easy to process, biocompatibility and the good advantage of wearability.
The present invention is achieved like this, and it comprises submicron Al
