Technical Field

The invention belongs to the technical field of tooth cosmetology, and particularly relates to a nano resin material for tooth carving.

Background

With the demand for beauty of people being higher and higher, people have a white and beautiful tooth and are more and more pursued, but many people are worried about dental plaque, yellow teeth and irregular tooth color. As such, beauty treatment of teeth is also being promoted in the oral industry. The existing tooth whitening method is porcelain tooth, has large grinding amount to natural tooth, long operation time, anesthesia requirement, high price and high requirement on bonding technology, and may have certain influence on periodontal. In recent years, nanometer dental sculptures are used as a new technology for beautifying oral teeth, advanced nanometer enamel regeneration technology is adopted, technical operation is carried out on the original teeth, various problematic teeth are improved and repaired under the painless and noninvasive conditions, whitening and tooth repairing are achieved, the requirements of the nanometer dental sculptures on used resin materials are high, the existing resin materials mainly depend on import, and the price is high.

Disclosure of Invention

In order to overcome the defects, the invention aims to provide a resin material for nanometer tooth carving, which has good color and luster, wear resistance, high bonding strength with a tooth body and difficult shedding.

In order to achieve the purpose, the invention adopts the following technical scheme:

a resin material for nanometer tooth engraving is prepared from the following raw materials in parts by weight:

15-25 parts of acrylate oligomer, 10-15 parts of triethylene glycol dimethacrylate, 5-10 parts of fluorinated polyurethane acrylate, 12-20 parts of hydroxypropyl methyl cellulose acetate succinate, 5-10 parts of phosphate monomer, 35-45 parts of glass powder, 5-10 parts of nano silicon dioxide, 1-4 parts of nano zirconium oxide, 0.3-0.6 part of nano diamond, 0.1-0.5 part of initiator and 0.8-1.2 parts of accelerator.

Preferably, the acrylate oligomer is bisphenol a bis glycidyl methacrylate, dimethylaminoethyl methacrylate or ethoxylated bisphenol a diacrylate.

Preferably, the phosphate ester monomer is 10-methacryloyloxydecyl dihydrogen phosphate 10-MDP or dipentaerythritol pentaacrylate phosphate ester PENTA.

Preferably, the particle size of the nano silicon dioxide is 15-50 nm.
