[0021] A preparation method of invisible monitoring orthopedic braces, comprising molding of the braces, preparation and molding of braces materials, the preparation of the invisible monitoring orthopedic braces comprises the following steps:
[0022] a Molding of braces
[0023] The holographic camera is used to obtain the patient's oral tooth information, and through diagnosis, the target tooth shape of the patient's correction is fitted by software, and a standard dental model is prepared; the software is a calculation simulation software such as Matlab;
[0024] b Preparation of polyurethane prepolymer
[0025] Under the protection of nitrogen atmosphere, add the dispersed conductive carbon material into the reaction kettle with condensing device and stirring device, control the temperature at 65-80°C and continue stirring, put isocyanate into the reaction kettle, and the mixture of isocyanate and conductive carbon material The mass ratio is 80-300:1, after 1 hour of reac...

[0035] a Molding of braces
[0036] The holographic camera is used to obtain the information of the patient's oral teeth, and through diagnosis, the software is used to fit the shape of the patient's target teeth for correction, and a standard dental model is printed with a 3D printer;
[0037] b Preparation of polyurethane prepolymer
[0038] Under the protection of nitrogen atmosphere, 1g of reduced graphene oxide dispersed by ultrasound (N,N-dimethylformamide dispersion) with a dispersion concentration of 5wt% was added to the reactor equipped with a condensing device and a stirring device, and the temperature Control the continuous stirring at 65°C, put 80g of toluene-2,4-diisocyanate into the reaction kettle, put 100 polytetrahydrofuran diol with a molecular weight of 1000 into the reaction kettle after reacting for 1 hour, continue the reaction for 1 hour, and then put it into the reaction kettle Add 30g of 2,2-dimethylolpropionic acid, heat up to 80°C and extend the ch...

[0044] a Molding of braces
[0045] The holographic camera is used to obtain the information of the patient's oral teeth, and through diagnosis, the software is used to fit the shape of the patient's target teeth for correction, and a standard dental model is printed with a 3D printer;
[0046] b Preparation of polyurethane prepolymer
[0047] Under the protection of nitrogen atmosphere, 1Kg of multi-walled carbon nanotubes (N-methylpyrrolidone dispersion) dispersed by ultrasound, with a concentration of 8wt%, was added to the reaction kettle with a condensation device and a stirring device, and the temperature was controlled at 80°C. Keep stirring, put 300Kg 4,4`-diphenylmethane diisocyanate into the reactor, put 600Kg of polyethylene glycol with a molecular weight of 2000 into the reactor after reacting for 1 hour, continue to react for 1-2 hours, and then pour into the reactor 60Kg of 1,4-butanediol was put in, and the temperature was raised to 95°C to extend the chain for...
