Problems solved by technology

However, when a single anterior tooth is discolored, a specific part of the tooth surface is deeply stained (brown plaque of fluorosis tooth, pigmented band of tetracycline tooth, etc.) big limit
Also, when unnecessary bleach comes into contact with the gums, it often causes gum inflammation
Even if the dentures can be partially trimmed clinically for these situations, there is still the problem of bleaching agent leakage, which affects the bleaching effect

Embodiment Construction

[0029] The method for preparing a temperature-sensitive magnetic targeting tooth whitening compound provided in the embodiment of the present invention includes the steps:

[0030] 101. Preparation of Fe modified by oleic acid 3 O 4 Nano magnetic particles;

[0031] 102. With the Fe 3 O 4 Nano-magnetic particles are used as the core and N-isopropylacrylamide is coated by miniemulsion polymerization to prepare composite A;

[0032] 103. Mix the compound A with carbamide peroxide at room temperature and stir for 2-4 hours, then centrifuge, and discard the supernatant to obtain the temperature-sensitive magnetic targeting tooth whitening compound.

[0033] Specifically, step 101 includes: taking FeC1 2 And FeC1 3 At least one of the substances is dissolved in deionized water, for example, 150-200g FeC1 2 And FeC1 3 Add 1L of deionized water and stir the mixture evenly. After heating to 60-70℃, add 30mL of ammonia and 20mL of oleic acid, and then keep stirring at constant temperature. Afte...

Abstract

The invention discloses a tooth whitening compound with temperature-sensitive magnetic targeting and its preparation and operation method, wherein the temperature-sensitive tooth whitening and cleaning compound contains strong oxidative peroxide The tooth-cleaning component of urea also contains iron ferric oxide nanoparticles and N-isopropylacrylamide as functional components, and is chemically self-prepared to form a urea peroxide complex with temperature-sensitive magnetic targeting. The compound of the present invention has the characteristics of low manufacturing cost, convenient operation, easy storage, and high positioning accuracy, and can realize targeted and controllable release of bleaching ingredients, solve the problem of bleaching agent leakage, and further improve the efficiency of tooth whitening. Quality, reducing side effects such as tooth sensitivity and gingival inflammation when unnecessary bleaching products contact the gums.

Description

Technical field [0001] The invention relates to a preparation for whitening human teeth, in particular to a tooth-cleaning compound with positioning treatment function and temperature-controlled release. Background technique [0002] The blemishes on discolored teeth, vital teeth and dead teeth have seriously affected the aesthetics of teeth. The aesthetic problems of teeth directly affect people's appearance and communication in daily life. People are eager to restore the natural color of teeth. Therefore, dental bleaching has become one of the important treatment items in oral clinic. [0003] Tooth bleaching technology is the most common cosmetic treatment. It is the simplest, least damaged, and most economical way to whiten teeth. The basic process is an oxidation reaction. The bleaching agent enters the discolored enamel and dentin to release bleaching substance. The effect of bleaching depends on the cause of the coloration, the location of the coloration, the depth, the le...
