Abstract
The invention discloses a preparation method of a tooth filling composite material. The method comprises the following steps: firstly, weighing various raw materials, adding partial raw materials to a mixer, and uniformly stirring the raw materials, so that a mixture is obtained; then, conducting ultrasonic disruption on the mixture; and finally, adding rest raw materials to the mixture which undergoes the ultrasonic disruption, and conducting stirring until the mixture is represented as a uniform paste, so that the tooth filling composite material is prepared. According to the scheme, the prepared tooth filling composite material can achieve good fusion with human teeth, and the tooth filling composite material is high in firming property and is not easy to become lost; the tooth filling composite material is simple and convenient to use, free from any toxic and side effects, safe and free from hidden health risks; and the preparation method has the advantages of being simple in process, easy to operate, high in yield, low in environmental pollution and the like.
Description
Technical field
The present invention relates to the preparation method of a kind of dental filling composite.
Technical background
Tooth is the organ of mankind's laboratory rodent chow.Tooth is the organ that human body is the hardest.It is said that in general, tooth is in vain
Color, quality is hard.The variously-shaped of tooth is applicable to multiple use, including tear, grate foods.In human language pronunciation and mouth
Front-seat upper and lower tooth is closely related.Tooth is organ the hardest in human body, is divided into corona, neck and root of the tooth three part.Again
It is divided into enamel, dentin, dental pulp etc..It is mainly composed of calcium hydroxy phosphate: i.e. alkali calcium phosphate, human teeth mainly comprises
Part.
Dental caries is commonly called as dental caries, decayed tooth, is bacterial disease, even can cause tooth with secondary pulpitis and periapical periodontitis
Groove bone and inflammation of jaws.As treated not in time, pathological changes continues development, forms cavity, destroys disappearance eventually to corona completely, its development
Final result be loss of tooth.Untreated cavity will not self-heal, its development final result be tooth funeral
Lose.Dental caries is bacterial disease, and therefore it even can cause alveolar bone and jawbone scorching with secondary pulpitis and periapical periodontitis
Disease.The method that treatment dental caries uses is mainly filling, will remove clean by the bad tissue of dental caries, be made certain hole shape, clean, sterilize
After, fill with filler, and recover the profile of tooth defect.The most shallow dental caries filling effect is best, controlling of middle dental caries and deep dental caries
Treat, after removing the bad tissue of dental caries, sometimes close to dental pulp at the bottom of hole, it is necessary to protect marrow agent refill adding one layer at the bottom of hole.Sometimes
Deep dental caries dental pulp after removing the bad tissue of dental caries just exposes, it is necessary to first takes endodontic treatment, then could fill.Filler
Main silver amalgam or complex filling gum.
Composite resin, compared with the repair materials such as Silver amalgam, has excellent biology, performance mechanical and attractive in appearance,
Become the topmost mode of current various tissue of tooth defect repair.But microenvironment is complicated, and influence factor is numerous.Beautiful
The graduate survey result of the state-run dentistry of state shows: existing resin dummy more than 50% needs to change, resin bonding reparation
The clinical life of body was less than 6 years, and only the U.S. is every year for changing the spending the most up to 5,000,000,000 dollars of the vertex-gluing graph body of defect.Tree
Fat material with formed firm and lasting bonding between tissue of tooth, be the determiner determining resin dummy service life, but
It is either hat side or root pipe dentin, the problem that all there is long-term bonding instability.
In prior art, the phenomenon that the implant being filled in tooth often falls off due to the effect of external force, so
Not only make troubles to patient, there is also bigger economic loss simultaneously.Since 20th century invention sixties photocuring dentistry tree
Since fat material, this class material, due to attractive in appearance nontoxic, easy to use, develops very fast.But owing to dental resin is polymerized
During volume contraction occurs, the sickness rate of patient's Secondary cases dental caries is higher, and the abrasive resistance of macromolecule resin and mechanics strong
Spend limited, therefore significantly limit the service life of dental resin material.Along with dental materials understanding is deepened by people, development
The novel dental resin material that a kind of high abrasion, mechanical strength are big, cubical contraction is little is particularly important.
Summary of the invention
Present invention aims to the deficiencies in the prior art, it is provided that one not only easily machine-shaping but also meet requirement of strength
The preparation method of dental filling composite.
It is an object of the invention to be achieved through the following technical solutions: the preparation method of a kind of dental filling composite, institute
The method of stating comprises the following steps: first weigh each raw material of following weight parts: polyacrylic resin 35-50 part, Corvic 10-
15 parts, chitin 35-50 part, chitin fiber 17-25 part, inorganic filler 10-15 part, polyvinyl alcohol 5-10 part, polyacrylic acid
N-butyl 10-16 part, silver source compound 12-30 part, stabilizer 6-9 part, antioxidant 8-12 part, cellulose gum 12-34 part, benzene first
Alcohol 8-23 part, distilled water 25-45 part, add in mixer by each raw material in addition to antioxidant and silver source compound, stirring
Mixture is obtained after Jun Yun；Then by mixture power at ultrasonic disruption 1-2 hour of 50-55W；Finally by antioxidant and silver
Source compound adds in the mixture after ultrasonic disruption, is 55-57 DEG C in temperature, under the conditions of rotating speed is 500-600 rpm, stirs
Mix and can be prepared by dental filling composite when being uniform paste body shape to mixture.
Described inorganic filler is silicon dioxide.
Described silver source compound is cyclohexyl butyric acid silver.
Described stabilizer is to methoxyl group phenol.
Described antioxidant is dibenzylatiooluene.
Beneficial effect: dental filling composite prepared by scheme of the present invention can merge very well with human teeth, and
Fastness is high, difficult drop-off；Easy to use and without any side effects, safety is without healthy hidden danger；Its preparation method has technique
Simply, easily operating, productivity is high, the advantages such as environmental pollution is little.
