Nano silver fluorine-containing self-acid pickling single bottle dental adhesive

Abstract

The invention relates to a nanometer silver fluorinated self-etching single bottle dentistry adhesive, belonging to the technical field of dentistry material. The component and the percentage of total weight is: 3.7 to 4.5 percent of initiator, 0.02 to 3.13 percent of additive, 0 to 2.0 percent of nanometer silver antimicrobial, 0 to 60 percent of methyl methacrylate monomer, 20 to 85.3 percent of acidity monomer and 0 to 53.3 percent of solvent. The acidity monomer comprises a phosphoric acid monomer or / and a carbonic acid monomer; the solvent is 0 to 4 kinds of materials selected from ethanol, propanol, normal butanol, acetone, methyl ethyl ketone, ethyl acetate and water. The nanometer silver of the invention can resist multiple bacterial and the nanometer biological ceramic powder canreduce regeneration caries; the single bottle self-etching function simplifies the using procedure; the mixture of multiple solvents with different permittivity can remarkably reduce the self hydrolysis of the acidity monomer and increase the chemical stability.

Description

technical field [0001] The invention belongs to the technical field of dental materials, in particular to a single-bottle multifunctional adhesive. Background technique [0002] Organic resin adhesives have been widely used in repair, restoration, reconstruction and orthodontics of dental materials. The product has changed from multi-step operation and single function to simple operation and multi-function. So far, the company has developed the seventh generation of adhesives. Compared with the early fourth-generation adhesives, there has been a qualitative leap in theory and technology. The fourth-generation adhesive adopts full acid etching and wet bonding technology. The application process includes acid etching, primer, and bonding, and is generally completed by multiple bottles of preparations. Its operation is time-consuming, and the bonding effect is affected by the operator's personal skills and experience. In the fifth-generation product, the primer and the adhe...
