Problems solved by technology

[0003] Before the use of adhesives, it was necessary to acid-etch the enamel to remove saliva, plaque, and other attachments on the surface, increase the surface energy, improve the wettability with the resin material, and then acid-etch the dentin to remove the smear layer, and then A series of complex processes such as rinsing the acid etching solution, applying pretreatment agent, drying and blowing, and lightly applying two layers of primer are cumbersome and may not be able to achieve a thin and uniform coating effect, and the restored teeth are not beautiful

Abstract

The invention relates to a dental adhesive resin and a preparation method thereof, and belongs to the field of medical dental materials. The dental adhesive resin comprises the following raw materials by weight: 10-18 parts of 37% phosphoric acid, 20-30 parts of MTAD, 25-35 parts of bisphenol A glycidyl methacrylate, 18-28 parts of hydroxyethyl methacrylate, 25-30 parts of hexafluorosilicate, 12-20 parts of bismethacrylate, 8-15 parts of a nanometer silicon filler, 1-5 parts of an antimicrobial agent, 15-30 parts of ethanol and 10-25 parts of water. The dental adhesive resin provided by the invention is easy to use and strong in bonding force, the formed film is thin and uniform, and the restored teeth are beautiful.

Description

technical field [0001] The invention belongs to the field of medical dental materials, and in particular relates to a dental bonding resin and a preparation method thereof. Background technique [0002] When there are broken teeth, defects, dentition defects, deformed teeth that are not suitable for correction, irregular dentition, crown discoloration, dead pulp teeth, fixed restorations for dentition defects, teeth after large-area filling, and fixed plugs When there are phenomena such as abutment teeth, it is necessary to make a crown for restoration. Adhesives must be used during restoration so that the crown and the tooth itself can be bonded together and perfectly combined before use. [0003] Before the use of adhesives, it was necessary to acid-etch the enamel to remove saliva, plaque, and other attachments on the surface, increase the surface energy, and improve the wettability with the resin material, and then acid-etch the dentin to remove the smear layer, and then...
