Problems solved by technology

However, most of the self-etching adhesives currently contain fluorine, such as the patent document CN101239024B, which is a fluorine-containing adhesive. Fluoride has strict control requirements in the application of dental materials, mainly because long-term intake of fluoride will lead to chronic systemic diseases. Especially for children, the harm of fluoride intake is more long-term
And the use of current self-etching adhesives may cause tooth hypersensitivity due to excessive acid etching or mechanical damage to dentin exposure

preparation example Construction

[0049] The preparation method of the dental self-etching adhesive with remineralization effect comprises the following steps:

[0050] (1) Dissolving the resin matrix in the reactive diluent, heating and stirring to mix evenly;

[0051] (2) After the above mixture is left to cool, first add the solvent to the above mixture, and after fully stirring, add the acid release agent, inorganic filler, thickener, remineralization component, stabilizer and colorant Into the above mixture, stir well to disperse the solid powder evenly;

[0052] (3) Add the photoinitiator, co-initiator and polymerization inhibitor in the above-mentioned mixture in a dark box, dark or red light environment, and stir evenly;

[0053] (4) The prepared mixture is defoamed and filled to obtain the dental self-etching adhesive with remineralization effect.

[0054] In step (1), the stirring and mixing conditions are: temperature 30°C-80°C, stirring speed 500-1500rpm, stirring time 0.5-2h.

[0055] In step (...

Abstract

The invention provides a dental self-acid etching adhesive with a remineralization effect, and a preparation method thereof. The dental self-acid etching adhesive comprises 8.0-10.5% of a resin matrix, 5-7% of an acid releasing agent, 0.7-1.2% of a photoinitiator, 2.8-4.1% of a remineralization component and the balance of auxiliary materials. According to the self-acid-etching adhesive, the remineralization component is added into the self-acid-etching adhesive and has a synergistic effect with the acid releasing agent, so that remineralization of dentin is realized on the basis of reducing dentin sensitivity, and tooth allergy caused by dentin exposure due to excessive acid etching or mechanical damage in the use process of the self-acid-etching adhesive can be avoided; meanwhile, dentin remineralization can be continuously guided for a long time, and dentin hypersensitivity can be prevented for a long time. On the one hand, the self-acid-etching adhesive does not contain fluoride, the product is safer, on the other hand, the self-acid-etching adhesive is a single-bottle self-acid-etching adhesive, the chemical stability is good, the bonding strength is high, and the ideal effect can be achieved when the self-acid-etching adhesive is used in cooperation with dental materials such as pit and fissure sealing agents.

Description

technical field [0001] The invention belongs to the field of tooth materials, in particular to a dental self-etching adhesive with remineralization effect and a preparation method thereof. Background technique [0002] At present, tooth etching agents can be divided into full-etching bonding system and self-etching bonding system according to the different treatment methods for the smear layer. The former mostly uses phosphoric acid with a concentration of 35%-38% to completely remove the stained layer, while the latter partially retains the stained layer and modifies it. The modified smear layer, dentin demineralized layer and adhesive together form a mixed layer to achieve the purpose of bonding. Since the full-etch bonding system is likely to cause postoperative sensitivity, it is gradually abandoned by most people and tends to use self-etching dentin bonding agents. Through continuous development and optimization, the self-etching adhesive has been reduced from the tra...
