Abstract

The invention discloses a long-acting antibacterial material, a dental film and a long-acting invisible appliance. The long-acting antibacterial material includes PETG resin and modified tourmaline; wherein, the mass ratio of PETG resin and modified tourmaline is 10 ~50:1; the preparation method of described modified tourmaline is: step S1, after nano tourmaline is processed through concentrated sulfuric acid, obtain porous nano tourmaline; Step S2, after porous nano tourmaline is processed through glycerin, obtain Hydroxylated porous nano-tourmaline; step S3, grafting hydroxylated porous nano-tourmaline with limonin to obtain modified tourmaline. The present invention combines PETG resin with modified tourmaline to prepare a safe, non-toxic, strong antibacterial effect and long-lasting antibacterial antibacterial material, and the present invention also applies the antibacterial material to dental diaphragms and invisible In orthotics.

Description

technical field

[0001] The invention relates to the field of antibacterial materials, in particular to a long-acting antibacterial material, a dental membrane and a long-acting invisible appliance. Background technique

[0002] With the gradual improvement of people's quality of life, consumption concept and aesthetic awareness, consumers pay more and more attention to the visual aesthetics of tooth arrangement and the aesthetic feeling of health, comfort and stability of articulation function. The development of invisible aligners has greatly improved the wearing Aesthetics make it more comfortable and convenient to wear, combined with digital 3D technology to make the orthodontic effect intuitive and predictable. At the same time, with the changes in the socio-economic structure, invisible aligners without brackets gradually penetrate into the orthodontic market and become a trend in the orthodontic industry.

[0003] The carrier of the invisible aligner is the aligner dia...
