Problems solved by technology

Dental adhesives are used in the mouth, there is a lot of water, the price ratio of the enamel surface is complicated, and the activities are more and more forceful. It is difficult to bond in the process of tooth repair. People have been exploring more effective dental adhesives for a long time. Although there are also a lot of results, the results are not satisfactory, and no satisfactory products have been developed.

Abstract

The invention provides a safe adhesive for dental implants and a preparation method of the adhesive. The safe adhesive for dental implants is prepared from raw materials as follows: polyethylene glycol-acrylate, 2-hydroxy-4'-(2-hydroxyethoxy)-2-methylphenylacetone, benzene sulfinic acid sodium salt, a biological compound, aluminum oxide, crosslinked polymethyl methacrylate, pretreated zirconium oxide, triclosan and the balance of a solvent. The safe adhesive for dental implants has no harm to tooth tissue and oral mucosa, does not decompose and age under the action of bacteria and enzyme in saliva, has higher adhesion for a dental material and has high bonding strength.

Description

technical field [0001] The invention relates to a dental adhesive, in particular to an adhesive for safe dental implantation and a preparation method thereof. Background technique [0002] Dental adhesives have been used in the restoration of teeth since more than half a century ago. In 1940, polymethyl methacrylate was used for the first time in dental repair surgery, but this dental adhesive was not widely used after that because it was not hard enough and the bonding force was not strong. It is known that a composite binder that is still in use until now appeared in 1965. The base material of this binder is polyfunctional methyl methacrylate, and the filler is inorganic powder. Dental adhesives are used in the mouth, there is a lot of water, the price ratio of the enamel surface is complicated, and the activities are more and more forceful. It is difficult to bond in the process of tooth repair. People have been exploring more effective dental adhesives for a long time. ...
