Embodiment 1

[0031] A 3D printing antibacterial restoration dental medical material, in parts by weight, includes the following components:

[0032] Diethylene glycol dimethacrylate monomer 15%

[0033] Bis-GMA resin 40%

[0034] Dimethicone 0.5%

[0035] Chitosan quaternary ammonium salt 4%

[0036] Initiator 2%

[0037] Color Additive 3%

[0038] 800 mesh silica 35.5%

[0039] The molecular weight of the chitosan quaternary ammonium salt described therein is 5000g / mol; The initiator is composed of camphorquinone and 2,4,6-trimethylbenzoylphosphonic acid ethyl ester in a mass ratio of 1:4; the color additive is It is composed of natural iron oxide, realgar and smoke black in a mass ratio of 4:1:1.

[0040] The preparation method of 3D printing antibacterial restoration dental medical material comprises the following steps:

[0041] (1) Stir and mix 80% of the acrylate monomer in the above formula ratio with Bis-GMA resin and defoamer at a temperature of 40-50°C;

[0042] (2) The r...

Abstract

The present invention relates to the technical field of 3D printing molding materials, particularly to a 3D printing antibacterial repair dental medical material and a preparation method thereof, wherein the 3D printing antibacterial repair dental medical material comprises, by weight, 10-20% of an acrylic monomer, 30-50% of a Bis-GMA resin, 0.3-0.8% of a defoaming agent, 3-5% of an antibacterial agent, 1-3% of an initiator, 1-5% of a color additive, and the balance of silica. According to the present invention, the tooth part printed from the 3D printing antibacterial repair dental medical material has advantages of low cost, high printing precision, good wear resistance and long service life; by selecting the chitosan quaternary ammonium salt, the 3D printing antibacterial repair dental medical material has good biocompatibility and good antibacterial effect, and the disadvantages of sterilization ability reducing, easy adsorption loss, easy drug-resistance generation and the like of the high traditional quaternary ammonium salt having the high mineralization degree can be overcome; and the preparation method has advantages of simple and easy-performing molding method, convenient operation, and wide material source.

Description

technical field [0001] The invention relates to the technical field of 3D printing molding materials, in particular to a 3D printing antibacterial dental restoration material and a preparation method thereof. Background technique [0002] Three Dimonsion Printing (Three Dimonsion Printing, referred to as Three DP) is a rapid prototyping technology that can divide the three-dimensional model data designed by the computer into layer model data, and build specific raw materials layer by layer until the entire entity is constructed. Three-DP molding has the advantages of low cost, no pollution in the working process, and fast molding speed. [0003] Rapid Prototyping Technology, also known as Rapid Prototyping Manufacturing (RPM) technology, was born in the late 1980s. It is a high-tech manufacturing technology based on the material accumulation method and is considered to be a major achievement in the manufacturing field in recent years. It integrates mechanical engineering, C...
