Abstract
The invention discloses a preparation method of an antibacterial and wear-resistant material for filling teeth. The preparation method comprises the following steps: firstly, weighing various raw materials, grinding partial raw materials into fine powder which is 800-1200 meshes in grain size, and uniformly mixing the fine powder, so that a powder mixture is obtained; then, dissolving rest raw materials in double distilled water, and conducting magnetic stirring and uniform mixing, so that a solution is obtained; and adding the powder mixture to the solution, and conducting stirring until the mixture is formed as uniform cream, so that the antibacterial and wear-resistant material is prepared. According to the scheme, the wear resistance of the prepared antibacterial and wear-resistant material is improved by 180%, and the teeth, which are repaired with the use of the material, are firmer and are more durable. The antibacterial and wear-resistant material is simple and convenient to use, free from any toxic and side effects, safe and free from health risks; and the preparation method has the characteristics 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 antibacterial high-abrasive material for dental filling.
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 white, quality is hard.The variously-shaped of tooth is applicable to multiple use, including tear, grate foods.Human language pronunciation is closely related with the upper and lower tooth in front row in mouth.Tooth is organ the hardest in human body, is divided into corona, neck and root of the tooth three part.It is divided into again enamel, dentin, dental pulp etc..It is mainly composed of calcium hydroxy phosphate: i.e. alkali calcium phosphate, the key component of human teeth.
Dental caries is commonly called as dental caries, decayed tooth, is bacterial disease, even can cause alveolar bone and inflammation of jaws with secondary pulpitis and periapical periodontitis.As treated not in time, pathological changes continues development, forms cavity, destroys disappearance eventually to corona completely, and the final result of its development is loss of tooth.Untreated cavity will not self-heal, its development final result be loss of tooth.Dental caries is bacterial disease, and therefore it even can cause alveolar bone and inflammation of jaws with secondary pulpitis and periapical periodontitis.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, after cleaning, sterilizing, fills with filler, and recovers the profile of tooth defect.The most shallow dental caries filling effect is best, middle dental caries and the treatment of deep dental caries, 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 is mainly with 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, it has also become the topmost mode of current various tissue of tooth defect repair.But microenvironment is complicated, and influence factor is numerous.The graduate survey result of US National dentistry shows: existing resin dummy more than 50% needs to change, and the clinical life of resin bonding dummy 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.Formed firm and lasting bonding between resin material with tissue of tooth, be the determiner determining resin dummy service life, but either hat side still 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, the most not only make troubles to patient, there is also bigger economic loss simultaneously.Since 20th century invention sixties photocuring dental resin material, this class material, due to attractive in appearance nontoxic, easy to use, develops very fast.But owing to occurring volume contraction in dental resin polymerization process, the sickness rate of patient's Secondary cases dental caries is higher, and the abrasive resistance of macromolecule resin and mechanical strength limited, therefore significantly limit the service life of dental resin material.Along with dental materials understanding is deepened by people, develop a kind of high abrasion, mechanical strength is big, cubical contraction is little novel dental resin material is particularly important.
Summary of the invention
Present invention aims to the deficiencies in the prior art, it is provided that a kind of not only easily machine-shaping but also meet the preparation method of the antibacterial high-abrasive material for dental filling of requirement of strength.
It is an object of the invention to be achieved through the following technical solutions: the preparation method of a kind of antibacterial high-abrasive material for dental filling, said method comprising the steps of: first weigh each raw material of following weight parts: Corvic 30-50 part, poly hydroxy ethyl acrylate 6-13 part, k eratin 6-15 parts, diallyl dimethyl ammoniumchloride 3-5 part, dimethyl dodecyl amine oxide 3-6 part, inorganic filler 12-15 part, silver source compound 6-13 part, cobalt dioxide 2-5 part, Poly-L-lactic acid 4-8 part, stabilizer 3-6 part, antioxidant 2-4 part, will be except distilled water, stabilizer, each raw material beyond antioxidant and silver source compound all grinds to form the fine powder that particle diameter is 800 ~ 1200 mesh, mix homogeneously, obtain mixture of powders；Again stabilizer, antioxidant and silver source compound are dissolved in distilled water, magnetic agitation mix homogeneously, obtain solution；Then mixture of powders is added in solution, temperature be 50 ~ 70 DEG C, rotating speed be 350 ~ 550 revs/min under the conditions of stir, stirring can be prepared by antibacterial high-abrasive material when being uniform paste body shape to mixture.
Described inorganic filler is ceramics.
Described silver source compound is silver acetate.
Described antioxidant is dibenzylatiooluene.
Described stabilizer is to methoxyl group phenol.
Beneficial effect: strengthening wearability in antibacterial high-abrasive material prepared by scheme of the present invention, its wearability improves 150%, makes the tooth utilizing material of the present invention to repair more sturdy and durable.Easy to use and without any side effects, safety is without healthy hidden danger；It is simple that its preparation method has technique, easily operates, and productivity is high, the advantages such as environmental pollution is little.
