Problems solved by technology

[0002] Food impaction can cause a variety of oral diseases. Wearing a food impaction blocker made of elastic denture material can prevent food impaction, but the elastic denture material is a high-density polycarbonate nylon composite material. Molecularly active plastics do not have the effect of preventing dental caries, and their bending strength, tearing strength, hardness and other indicators are not ideal

Embodiment Construction

[0014] An elastic denture material with NaF added and its preparation process, the specific experimental process is:

[0015] (1) NaF was added to the elastic denture particle material, and the amount of NaF added was treated in four ways, that is, the concentration of NaF added to the elastic denture material was 0, 0.4%, 0.8%, and 1% (weight ratio);

[0016] (2) Dissolve the NaF treated above in the self-curing resin monomer;

[0017] (3) Mix the product obtained in step (2) with the elastic denture granular material evenly or spray directly on the surface of the elastic denture granular material;

[0018] (4) After the solvent is volatilized, NaF is uniformly attached to the elastic denture particle material, conventional sol injection molding, and pressure injection molding to make the test piece required for the experiment, that is, the food impaction blocker;

[0019] (5) Submerge the food impaction stopper obtained in step (4) into four jars filled with artificial sali...

Abstract

The invention discloses an elastic false tooth material with NaF and a preparation process thereof. The preparation process comprises the following steps of: adding NaF into the elastic false tooth material in percentage by weight; then, dissolving NaF in a self-curing resin monomer; then, uniformly mixing the product obtained and the elastic false tooth material or directly spraying the product obtained to the surface of the elastic false tooth material; pressing into a food impaction apparatus or other test pieces through normal sol injection molding. The fluorine-containing elastic false tooth material disclosed by the invention not only has good ageing-resistant performance and long service life of the food impaction apparatus or other test pieces, but also has remarkable caries prevention effect.

Description

technical field [0001] The invention relates to an elastic denture material, in particular to an elastic denture material added with NaF and a preparation process thereof. Background technique [0002] Food impaction can cause a variety of oral diseases. Wearing a food impaction blocker made of elastic denture material can prevent food impaction, but the elastic denture material is a high-density polycarbonate nylon composite material. Molecularly active plastics do not have the effect of preventing dental caries, and their bending strength, tearing strength, hardness and other indicators are not ideal. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art, and provide a kind of elastic denture material and its preparation process with NaF added, the food impaction stopper made by this process not only has good anti-aging performance, but also has obvious anti-caries effect. [0004] The technical scheme ...
