Problems solved by technology

However, composite resins also have certain problems. The mechanical strength is not high enough to be used on the heavily loaded posterior teeth, the wear resistance is also poor, and the volume shrinks greatly when polymerization and curing occur. These limit the application range of composite resins. and service life

Embodiment 1

[0044] A modified silane coupling agent, which is prepared as follows:

[0045] Add 3-chloropropyltriethoxysilane and triethylamine (the molar ratio of 3-chloropropyltriethoxysilane and triethylamine is 1:1) into the tank with reflux device, thermometer and dropping funnel In the four-neck flask, start a strong stirrer, add 3-amino crotonate isopropyl ester (1:1 molar ratio to 3-chloropropyltriethoxysilane) dropwise into the flask within 30 minutes, and gradually raise the temperature to 80 ℃, reflux reaction for 5 hours; suction filtration to remove the amine salt precipitate, and the filtrate was purified by vacuum distillation, that is, the modified silane coupling agent; the whole reaction process was protected by nitrogen and strictly waterproofed. The structural formula of the modified silane coupling agent is:

[0046] .

[0047] Structure Characterization: 1 H NMR (400 MHz, DMSO-d6): 4.56 (m, 1H, C H -(CH 3 ) 2 ), 4.11 (s, 1H, C=C H ), 3.89 (m, 6H, Si-O-C H ...

Embodiment 2

[0052] The preparation of a modified silane coupling agent is the same as in Example 1.

[0053] A tooth restorative material for oral science, the raw material components of which are different from those in Example 1 in that the base resin is Bis-GMA resin.

[0054] The preparation of a dental restorative material for oral science is the same as in Example 1.

Embodiment 3

Abstract

The invention discloses a dental restoration material for oral science and a preparation method of the dental restoration material, and relates to the field of medical materials. The dental restoration material for oral science comprises a base resin including at least one of Bis-GMA and UDMA, a filler and a photoinitiator, wherein the filler comprises at least one of modified silane coupling agent modified barium glass powder and modified silane coupling agent modified silica fume. The dental restoration material prepared by the invention has excellent mechanical strength, strong wear resistance and low polymerization shrinkage rate. The water absorption and the solubility are obviously reduced, the service life of the restoration material is prolonged, the use toxicity of the restoration material is reduced, the occurrence rate of periodontitis is reduced, and the use range of the restoration material is expanded.

Description

technical field [0001] The invention belongs to the field of medical materials, and in particular relates to a dental restoration material for stomatology and a preparation method thereof. Background technique [0002] With the continuous development of medical materials and technology in our country, more and more advanced materials have been continuously applied. The number of patients with oral diseases continues to increase, and high-tech materials in advanced materials are applied to them and have very good clinical effects. Especially the use of high-tech materials as fillings in tooth defects has made great achievements. Dental restoration is to prepare teeth according to the principles of retention, resistance and protection of pulp-dentine organs on the basis of removing the damaged or severely weakened tooth tissue, and finally restore its inherent shape with specific materials through a certain procedure and function. Dental defects are mainly caused by dental ...
