Description
Technical field
The present invention relates to a kind of antibacterial durable dental filling composite and preparation method thereof.
Technical background
Dental caries is commonly called as dental caries, decayed tooth, is bacterial disease, can secondary pulpitis and periapical periodontitis, even can cause alveolar bone and inflammation of jaws.As treated not in time, pathological changes continues development, forms cavity, and destroy disappearance completely to corona eventually, the final result of its development is loss of tooth.Dental caries feature is that sickness rate is high, and distribution is wide.Being the main commonly encountered diseases in oral cavity, is also one of the most general disease of the mankind, and itself and tumor and cardiovascular disease are listed as the large keypoint control disease of the mankind three by World Health Organization (WHO).1. dental caries is to the harm of adult: the inflammation 1. often causing the positions such as apex of root of tooth, local swelling time serious; As pus and antibacterial are absorbed, septicemia or bacteremia can be caused.2. bad root of the tooth can not laboratory rodent chow; Increase the weight of gastrointestinal tract burden.3. for old people, serious dental caries are bad can cause major part or whole absence of tooth, is unfavorable for that old people's is healthy.2. 8 of children caries large hazardness: 1. dental defect, can reduce masticatory function when relating to multiple deciduous molar; 2. in cavity, food debris is detained, and bacterial accumulation, makes oral hygiene worsen, and affects permanent teeth generation dental caries and suffers from; 3. permanent teeth dental gram is inherited in the impact of deciduous teeth periapical periodontitis, causes its enamel development and normal eruption obstacle; 4. deciduous teeth early lose because of dental caries, cause permanent teeth gap shrinks, because malposition occurs gap deficiency; 5. the oral cavity mucous membrane tissue of the corona easy damaged local of Deciduous Caries breakage; 6. Deciduous Caries is serious, causes masticatory function to reduce, affects the nutrition intake of child, impact growth promoter; 7. caries in primary teeth develops into periapical disease and can be used as its hetero-organization generation focal infection that focus tooth makes body; 8. attractive in appearance and orthoepy is affected.Drug therapy is on the bad basis of worn dental caries, and drug application suppresses the method for dental caries development, is applicable to the shallow dental caries of permanent teeth not yet cavitation, shallow, the middle cavity of newborn labial teeth.Common drug comprises ammoniacal silver nitrate and sodium fluoride etc.To the tooth forming substantive defect, plombage is the current most widely used general and good method of effect, and its basic process can be divided into two steps: first remove the bad weak tissue of tooth organized and lose support of dental caries, and by certain requirement, rational form is made in nest hole.Then fill with filler and recover its intrinsic morphology and function.Filler has silver amalgam, composite resin etc.Wherein silver amalgam firm, not easily consume but attractive in appearance not, composite resin is attractive in appearance, close to the natural color of tooth, but intensity is not as silver amalgam, easy loss, in most of the cases, the surface chemistry composition of existing composite resin material is difficult to meet above-mentioned requirements with structure, usually will adopt surface modification treatment, as graft copolymerization, to improve its performance.In addition, material also needs excellent processing forming, is easily processed into the complicated shape of needs.So need the filling tooth material developed a kind of not only easily machine-shaping but also meet requirement of strength.
Summary of the invention
The object of the invention is to for the deficiencies in the prior art, a kind of not only easily machine-shaping but also the antibacterial durable dental filling composite meeting requirement of strength and preparation method thereof are provided.
The object of the invention is to be achieved through the following technical solutions: a kind of antibacterial durable dental filling composite, be made up of the component of following weight: polymethyl methacrylate 30-40 part, calcium hydroxy phosphate 20-25 part, acetoacetoxyethyl methacrylate 13-15 part, fimbrin 3-8 part, 2-mercapto benzimidazole 1-3 part, consisting of phase-transferring agent 5-12 part, glycosaminoglycan 12-30 part, steamed bone meal 5-10 part, cyclohexyl butyric acid silver salt 4-8 part, casein 3-5 part, hydroxyanisol 4-8 part, antioxidant 3-8 part, sorbitol 12-24 part, benzyl alcohol 8-23 part, distilled water 25-45 part.
Described consisting of phase-transferring agent is positive tetrabutyl ammonium bromide.
Described antioxidant is 2,6 ditertiary butyl p cresol.
A kind of preparation method of antibacterial durable dental filling composite, said method comprising the steps of: step 1, take each component by weight, each component except acetoacetoxyethyl methacrylate and cyclohexyl butyric acid silver salt is added in mixer, after stirring, obtain mixture; Step 2, by mixture ultrasonic disruption 1-2 hour; Step 3, acetoacetoxyethyl methacrylate and cyclohexyl butyric acid silver salt are added in the mixture that step 2 obtains, be 55-57 DEG C in temperature, under rotating speed is 500-600rpm condition, is stirred to when mixture is even paste body shape and can obtains dental filling composite.
Described step 2, ultrasonic power is 35-45W.
Described step 3, mixing speed is 550-560rpm.
The invention has the beneficial effects as follows: composite of the present invention improves histocompatibility and blood compatibility; There is antibiotic property, improve and improve mechanics, machinery, physical property, not easy to wear durable; It is simple that its preparation method has technique, the advantages such as easy to operate, productive rate is high, and environmental pollution is little.
