Embodiment 1

[0036]Under the condition of avoiding light, put 4.95g of liquid resin in a black plastic bottle for use. Add 0.05 g of core-shell CHX / ACP nanospheres into a black opaque plastic bottle under dark conditions, mix it evenly with a mixing knife, vacuumize to remove air bubbles, and store the obtained material in a sealed and dark place. As 1% CHX / ACP group. Fill the above resin into a cylindrical mold with a diameter of 10mm and a height of 1.5mm. The upper and lower surfaces of the mold are respectively covered with polyethylene film and glass slides, and the excess material is removed, cured with a light curing lamp for 20s, and the specimen is demoulded and placed for 24 hours spare.

[0037] Soak the specimen in 10ml of deionized water, place it in a constant temperature box at 37°C, and soak for 1, 4, 7, and 14 days respectively. At each detection time point, the extract was collected for detection, and fresh deionized water was replaced to continue soaking. The concentr...

Embodiment 2

[0040] Under dark conditions, 4.75g of fluid resin was placed in a black plastic bottle for use. Add 0.25 g of core-shell CHX / ACP nanospheres into a black opaque plastic bottle under dark conditions, mix it evenly with a mixing knife, vacuumize to remove air bubbles, and store the obtained material in a sealed and dark place. As 5% CHX / ACP group. Fill the above resin into a cylindrical mold with a diameter of 10mm and a height of 1.5mm. The upper and lower surfaces of the mold are respectively covered with polyethylene film and glass slides, and the excess material is removed, cured with a light curing lamp for 20s, and the specimen is demoulded and placed for 24 hours spare.

[0041] Soak the specimen in 10ml of deionized water, place it in a constant temperature box at 37°C, and soak for 1, 4, 7, and 14 days respectively. At each detection time point, the extract was collected for detection, and fresh deionized water was replaced to continue soaking. The concentration of ...

Embodiment 3

[0044] Under dark conditions, 4.5g of clean resin was placed in a black opaque plastic bottle for later use. Add 0.5 g of core-shell CHX / ACP nanospheres into a black plastic bottle under dark conditions, mix it evenly with a mixing knife, vacuumize to remove air bubbles, and store the obtained material in a sealed and dark place, recorded as 10% CHX / ACP group. Fill the above resin into a cylindrical mold with a diameter of 10mm and a height of 1.5mm. The upper and lower surfaces of the mold are respectively covered with polyethylene film and glass slides, and the excess material is removed, cured with a light curing lamp for 20s, and the specimen is demoulded and placed for 24 hours spare.

[0045] Soak the specimen in 10ml of deionized water, place it in a constant temperature box at 37°C, and soak for 1, 4, 7, and 14 days respectively. At each detection time point, the extract was collected for detection, and fresh deionized water was replaced to continue soaking. The con...

Abstract

The invention discloses an oral cavity fluid resinous material. The oral cavity fluid resinous material is prepared from the following components in percentage by mass of 1%-10% of core-sheath CHX / ACPnanospheres and 90%-99% of trade goods fluid resin. The invention provides a preparation method of the oral cavity fluid resinous material. The oral cavity fluid resinous material disclosed by the invention has the beneficial effects that nanospheres prepared by a nanometer medicine-carrying technique are used as fillings, the trade goods fluid resin can release calcium and phosphorus ions and chlorhexidine at the same time, besides, remineralization and bacterium resistance properties can be given to the trade goods fluid resin, and the oral cavity fluid resinous material is convenient to apply to oral cavity bonding and repairing materials; and the content of the nanosphere fillings is adjusted, so that a series of tooth department fluid resinous materials having different medicine release quantities are obtained. The fluid resin prepared by the preparation method is beautiful in appearance, uniform in internal fillings and good in mechanical properties; and the preparation method is simple and easy to operate and suitable for large-scale preparation and production.

Description

technical field [0001] The invention relates to the technical field of medical materials, in particular to an oral fluid resin material and a preparation method thereof. Background technique [0002] Oral fluid resin materials are more and more widely used in the field of oral cavity because of their good aesthetics, minimally invasive treatment, convenient operation and high curing depth. However, the current commercialized fluid resins lack antibacterial properties and remineralization properties, and cannot avoid the formation of secondary caries, which affects the long-term life and curative effect of their clinical restorations. Studies have shown that secondary caries is the primary cause of resin restoration failure. Therefore, how to endow oral fluid resin with good and stable antibacterial properties and remineralization properties to overcome secondary caries has become one of the problems to be solved in the field of oral cavity. [0003] In previous studies, an...
