Technical field
The invention belongs to biomedical material technologies, and in particular to a kind of dental filling resin material and preparation method thereof.
Background technique
Tooth is the organ of mankind's laboratory rodent chow.Tooth is the most hard organ of human body.In general, tooth is in white
Color, quality are hard.The various shape of tooth is suitable for multiple use, including tearing, grate foods.Tooth is most hard in human body
Organ, main component be alkali calcium phosphate.
Saprodontia is also known as decayed tooth or decayed tooth, is bacteriosis, can it is secondary be pulpitis and periapical inflammation, when serious even energy
Cause alveolar bone and inflammation of jaws.Such as it is not treated in time, lesion continues to develop, and cavity is formed, destroys disappearance completely to corona eventually,
Its final result developed is loss of tooth.The cavity of untreated will not self-heal.
The method for treating saprodontia mainly fills, i.e., removes completely dental caries bad tissue, be made certain hole shape, clean, disappear
It is filled after malicious with filling dental prosthetic material, and restores the shape of tooth defect.Currently, teeth repairing material generally uses silver
Mercury alloy, glass ionomer, Nano diamond resin and nanometer titanium dioxide silicone resin.
Silver amalgam is a kind of specific alloy, and silver amalgam is the amalgam of mercury and the interaction of silver-tin alloy powder at normal temperature
Compound, silver amalgam are the most commonly used teeth repairing materials.Contain various metals in silver-tin alloy powder, such as silver, tin, copper and
Zinc etc., and being made by proper proportion, therefore the shortcomings that other metals can be compensated with a kind of the advantages of metal, have silver amalgam
There are expansion appropriate, enough intensity and hardness, the outstanding performance such as creep is small, and the time is appropriate admittedly firmly.But in silver amalgam
Containing environmentally harmful mercury, therefore silver amalgam is gradually eliminated.
Glass ionomer cement is that glass reacts condensate of the generation containing ionic bond with polyacrylic acid.By pulvis and liquor
Two components are constituted.Pulvis is by SiO2、Al2O3、CaF2、AlPO4、Na3AlF6It mixes in proportion, through 1000~1400 DEG C of high temperature meltings
Melt into glass, then in water be quenched after grind, pulvis.Liquor uses the copolymer of acrylic acid and itaconic acid or maleic acid.
Glass ionomer water valve and its have the characteristics that good caking property, biological safety, anti-caries and dissolubility resistent, at present
It is widely used in bonding, filling, lining and rebasing etc..But Glass ionomer cement surface hardness and wearability are poor, no
Easily be processed by shot blasting, and its operating technology require it is stringent, getting wet early stage Hirschfeld-Klinger reaction may cause bubble, crackle and
It is dissolved with poststaining and material.
