Anti-caries invisible orthodontic appliance with antibacterial coating as well as preparation method and application of anti-caries invisible orthodontic appliance

The invention provides an anti-caries invisible orthodontic appliance with an antibacterial coating as well as a preparation method and application of the anti-caries invisible orthodontic appliance. The anti-caries invisible orthodontic appliance comprises an invisible orthodontic appliance and the antibacterial coating arranged on a contact surface of the invisible orthodontic appliance and teeth, the preparation raw materials of the antibacterial coating comprise a combination of a photocuring polymeric monomer, a diluent, a photoinitiator, a polymerization inhibitor, an antibacterial agent and an antioxidant; according to the anti-caries invisible orthodontic appliance, the contact surface of the anti-caries invisible orthodontic appliance which is in direct contact with teeth is coated with the antibacterial coating, so that colonization of bacterial plaque on the tooth surface is fundamentally inhibited, and furthermore, chalk spots are prevented by reducing the biological activity of the bacterial plaq
