preparation example Construction

[0029] The preparation method of the dental whitening and antibacterial coating material comprises the following steps:

[0030] (1) Mix the powder materials in proportion, SiO 2 , The mass sum of piezoelectric materials and additives is 100%.

[0031] (2) Mill the material obtained in step (1) at high speed in a ball mill to obtain a mixture. The milling speed is 800-2000r / min, preferably 1000-1500r / min, and the milling time is 2-16h, preferably 10-16h.

[0032] (3) mixing the mixture obtained in step (2) with the blending liquid to obtain a paste material; the blending liquid is used as a mixture dispersion to improve adhesion, and is composed of glycerin, water and povidone K30, and the mass ratio It is (2-4): (3-5): (1-4), preferably 4:5:1; the mass ratio of the mixture to the blended liquid is (2-3): (1-2), preferably 2: 1;

[0033] (4) Apply the paste material obtained in step (3) to the outside of the dental restoration matrix, completely wrap the dental restoration ...

Abstract

The invention discloses a dental whitening and degerming coating material and a preparation method and application thereof. The coating material is composed of SiO2, an additive and a piezoelectric material. A dental prosthesis with the surface layer containing the piezoelectric material is prepared by coating and curing the surface layer of the dental prosthesis, and SiO2 serves as a main material and can activate the piezoelectric property of the material due to pressure changes under the action of external force such as vibration and friction in daily life due to the piezoelectric material, so that a large number of active groups are generated. Research shows that the active groups generated by the piezoelectric effect can effectively remove stains on the surfaces of teeth and remarkably whiten the teeth, no side effect exists, enamel and oral mucosa cannot be damaged, and then the self-whitening and degerming functions of the teeth are achieved through the piezoelectric effect on the surfaces of the teeth in the chewing and tooth brushing process.

Description

【Technical field】 [0001] The invention belongs to the technical field of teeth whitening and repairing, and in particular relates to a dental whitening and antibacterial coating material and its preparation method and application. 【Background technique】 [0002] In the field of stomatology, with the improvement of public aesthetic requirements, dental restoration materials must not only meet good biocompatibility and excellent mechanical properties, but also have good optical properties to meet the aesthetics of the restoration. [0003] Teeth whitening is an important aspect of oral aesthetics. At present, teeth whitening is mainly achieved through abrasives or whitening agents. Abrasives are used to remove stains and stains on the surface of teeth by grinding. This method is a physical action method. Abrasives often have relatively high hardness. Therefore, with the increase in the number of grinding times, certain damages will inevitably be caused on the tooth surface, a...
