Abstract
A long-acting whitening agent for teeth is a double-component tooth enamel prepared from acrylepoxy resin, SiO2, TiO2, polymerization inhibitor, initiating agent, reduction promotor and solvent. After two components with same quantity are mixed, the mixture is coated onto cleaned, acid etched and dried surface of tooth and then solidified at ordinary temp. Then, a layer of brightening ester is coated on its surface for high lustre. Said brightening easter is same as the tooth enamel, but does not contain SiO2 and TiO2. It features long storage period (more than one year) and durable application (more than half a year).
Description
What the present invention relates to is the dental prosthetics articles for use, particularly is main formulated dental prosthetics product with the organic high molecular compound.
(long-term transition smoking, drink strong tea, chew Semen Arecae etc.), the high fluorinated water of long-term drink and take some drugs (particularly tetracycline) and cause tooth to be ash, color such as yellow, purple, black because some living habit are not attractive in appearance to people's utmost point.Desire to make this tooth to become attractive in appearance, method commonly used at present has methods such as pickling, bleaching, porcelain, facing brushing brightening agent.Pickling, bleaching change effectively light color and skin color, but the tooth body is diminished and easily produce allergy; The porcelain tooth puts stainless steel sleeve to tooth after polishing, put on the porcelain facing that is fired into again and form, and its color and luster, intensity are all fine, but operating process is big to injury of teeth, and difficulty is big, expense is high.Is that the main brightening agent of forming is reasonable in the dental surface brushing by organic high molecular compound, tooth and oral cavity is not had any infringement, and tooth is had certain protective role, simple and easy to do and spend less.Provide with a kind of acrylic acid as US4032627--the make-up composition that acrylic copolymer resin is formed, divides to be coated in that curing forms on the facing after three blendings.CN ZL92109996.7 is a kind of compositions based on acrylate and polymer thereof, is coated in during use to solidify on the tooth to form.But its adhesive strength, scuff resistance are not high, thereby service life is shorter.
The present invention is that to select a kind of acrylic acid grafting ester for use be main, is mixed with the brightening agent that the long-acting dental surface of high-adhesive-strength, high abrasion resistance strength is modified.
The substrate resin that the present invention selects for use is an acrylic acid epoxy resin.The statistics of World Health Organization (WHO) shows that this material is the longest for 16 years in retention time on the human body as child's caries preventive agent, and without any side effects to human body.With this resin be the combination resin of base material in the polymerizing curable process can with pig, cattle, to the marrow with people's dentin in collastromin generation graft copolymerization, the resin after the polymerization can be bonded on sclerotin and the facing securely.The structural formula of the acrylic acid epoxy resin that the present invention selects for use is:
N=1～10 wherein.This resin can be made in the presence of catalyst by acrylic acid and epoxy resin.In the presence of the organic peroxide evocating agent and reduction accelerator (organic amine) of minute quantity, this resin can produce cross-linking reaction rapidly at normal temperatures and solidify.The solvent that uses in the prescription is low-molecular-weight acrylate and styrene, and its effect is to be solvent before unreacted, also participates in reaction in reaction, avoids existing in some prior aries solvent not participate in the solidified shortcoming that delays of reaction.In order to strengthen anti-wear performance and to adjust color, selected SiO in the prescription for use
2, porcelain powder, ZnO, TiO
2And pigment.Never degenerate in order to produce the longer-term storage, in raw material, can not contain the impurity that can cause polyreaction, add a spot of polymerization inhibitor (hydroquinone) in the prescription, and make the dosage form of bi-component, promoter and initiator are dissolved in respectively in two components, now allocate getting final product during use.A of the present invention, the B two contained things of component dentium nitor fat and weight percent thereof consist of:
A B
Acrylic acid epoxy resin 30～50 68～85
Reinforcing agent SiO
230～60
Toner TiO
20.5～1.0
Polymerization inhibitor 0.02～0.08 0.02～0.08
Initiator 0.5～3.0
Reduction accelerator 0.8～5.0
If solvent 6～25 11～28 desire to make dentium nitor fat to be coated with the more beautiful repaste thereon of brush layer one deck fat that adds lustre to, the weight percent of the fat bi-component of adding lustre to consists of
C D
Acrylic acid epoxy resin 72～90 68～90
Polymerization inhibitor 0.02～0.08 0.02～0.08
Initiator 0.8～3.0
Reduction accelerator 1.5～5.0
What the polymerization inhibitor in solvent 7～25 8～28 prescriptions used is hydroquinone; Initiator is an organic peroxide, as benzoyl peroxide, 2, and 4--dichlorobenzoperoxide etc.; Reduction accelerator is an organic amine, and as N, N--dimethylaniline, dihydroxy ethyl are to monomethylaniline., diethylenetriamine etc.; What solvent used is low-molecular-weight acrylate, as methyl ester, ethyl ester, isopropyl ester, glycol ester or the dimethyl SiO of methacrylic acid
2Acrylic acid glycol esters etc. also use fragrant alkene such as styrene etc.; SiO
2With TiO
2Be ultra-fine granularity, SiO
2(≤300 order) also can use the ultra-fine SiO that handles through silanization
2, TiO
2Granularity is≤400 orders.Compound method is: the A component: according to the order of sequence polymerization inhibitor, initiator are joined stirring and dissolving in the solvent; Reinforcing agent and toner are added in the acrylic acid epoxy resin, more above-mentioned solution are added after stirring, restir evenly forms, and is the milky glue solution of sticky shape; The B component: polymerization inhibitor, reduction accelerator are added to stirring and dissolving in the solvent, and then being added to stirs in the acrylic acid epoxy resin forms, for slightly little Huang to colourless translucent glue, its ratio of viscosities A component is little.Be respectively charged in the extrudable pipe.The fat that adds lustre to also is so preparation and packing.Product is stored down more than 1 year in low temperature, and is not stratified, do not produce precipitation, and serviceability does not have significant change.The A, B two components that extrude equivalent during use from the storage pipe of storing dentium nitor fat A, B component respectively mix well in 20S in same accent fat spoon, and brushing is at cleaning, acid etching and exsiccant dental surface, 5min finishes, the seam of picking one's teeth then, 10～15min solidifies, the coating surface hardening; As needs, repaste one deck fat that adds lustre to after the brushing of dentium nitor fat, its allotment and brushing method such as dentium nitor fat wait to solidify that afterwards coating is hard, color is as white as polished jade, and have enamel gloss, and is very attractive in appearance.Number pick up routine facing beauty treatment person handle with product brushing of the present invention later half do not see to 1 year wear and tear or come off.
The characteristics that the present invention has are: (1) formula for a product is reasonable, making is simple.Use acrylic acid epoxy resin as polymeric substrate, acrylate not only as solvent but also be two component dosage forms that polymerization single polymerization monomer, the initiator that can induce reaction and reduction accelerator preserve separately are formed, this product that constitutes of several adjuvants in addition, never degenerate for a long time when depositing, can react rapidly during use; (2) result of use is good: the adhesive strength height, and wear-resisting, damage tooth not after the use, spotless white facing can keep considerable time; (3) use simply, medical department can use, and the beauty parlor also can use.
