Description
Technical Field
The invention relates to a dental oxygen-barrier isolating sealant, a preparation method and a use method thereof, belonging to the technical field of dental auxiliary materials.
Background
Oxygen scavengers are used for resin restoration because all photocurable resins do not guarantee complete cure in an aerobic environment. When resin is filled, firstly, dental mechanical preparation and chemical preparation are carried out, after the preparation, an adhesive is coated for resin layered filling or layer filling, when the last layer is filled, the surface of the resin is actually exposed in the outside air, in this case, the resin cannot be completely hardened by pure illumination, so that the strength of the material is influenced, the surface is easily soft, and scratch and fracture are easily caused. The existing oxygen inhibitor is prepared from silicon dioxide, glycerol and distilled water, and the oxygen inhibitor has the main problem of blocking oxygen and light transmission, so that incomplete curing of the dental filling resin is caused.

Drawings
FIG. 1 is a schematic view of the production process of the dental oxygen barrier sealant of the present invention.
Detailed Description
For a better understanding of the present invention, reference will now be made in detail to the present invention by way of specific embodiments thereof. Wherein the raw material used in the examples of the present invention is distilled water (H) 2 O), CAS:7732-18-5; glycerol (C) 3 H 8 O 3 ) CAS:56-81-5; crosslinked polyacrylic acid resin (C) 3 H 4 O 2 )，CAS：9003-01-4。
Example 1
A preparation method of a dental oxygen barrier and isolation sealant comprises the following process flows of sending and taking raw materials, mixing 69.5 parts of glycerol and 29.5 parts of water according to the process flow shown in figure 1, stirring at 600r/min, adding 1 part of carbomer 980 cross-linked resin, stirring at 600r/min, adding 4 parts of 50% triethanolamine aqueous solution for neutralization, preparing 50% triethanolamine solution with the mass concentration of 99% by using distilled water, adding 4 parts of 50% triethanolamine solution into each part of cross-linked polyacrylic resin, checking, measuring the pH value by using a pH meter to be 6.6-7.1, and measuring the viscosity by using a viscometer to be 70000mpas. The color and the uniformity of the product are visually inspected by self-inspection. And (5) well writing the inspection record, making a finished product identifier, and noting the name, batch number, weight, production date and the like of the finished product. The step is a step before filling, and can be filled after the inspection is qualified by an inspector. And then entering a finished product warehouse for delivery, after-sale service and the like.
The dental oxygen barrier sealant prepared in the above example was tested on a glass slide at an angle of 45 degrees, and the dental oxygen barrier sealant hung on the glass slide did not flow, and the light passing rate was the highest and reached 90% in the test of the luminometer.
Comparative example 1
An oxygen barrier agent was prepared from 1 part of silica, 69.5 parts of glycerin, and 29.5 parts of distilled water.
Product instructions:
1. fixing the ceramic or composite prosthesis with bonding resin.
2. Excess resin was removed.
3. The repair edge is coated with the oxygen barrier and isolation sealant prepared in the embodiment 1, and the surface to be coated is completely covered, wherein the thickness is 1mm.
4. And (3) photo-curing the bonding resin.
5. The oxygen barrier sealant was then flushed away with water.
6. The prosthesis is trimmed/polished.
Meanwhile, the oxygen-blocking agent prepared in the comparative example 1 is used for carrying out a comparative test, and the result shows that the oxygen-blocking isolating sealant prepared in the invention is transparent gel, the transparent gel can not block the transmission of light while blocking oxygen, and the dental filling resin is fully cured under the irradiation of specific light, so that the quality and the strength of photocuring are not influenced.
