Embodiment 1

[0018] A denture hydrogel spacer material is made of the following raw materials in parts by weight:

[0019] Palm fiber 5, sodium hypochlorite 3, peppermint oil 4, longan core 2, nettle root 3, chitosan 30, polyvinyl alcohol solution 50, glutaraldehyde solution 15;

[0020] The mass fraction of the glutaraldehyde solution is 30%. .

[0021] Further, the preparation method of the polyvinyl alcohol solution is as follows: adding polyvinyl alcohol into deionized water 5 times its volume, heating to 40°C to fully dissolve it, then adding tea tree oil, stirring evenly, and placing it in a water bath at 70°C , stirred and swelled for 3h, then raised the temperature to 80°C and stirred for 20min.

[0022] Further, its preparation method comprises the following steps:

[0023] (1) Put the palm fiber into a pulverizer for 10 minutes, pass through a 200-mesh sieve, immerse in distilled water 15 times the volume of the palm fiber, heat and stir until boiling, let it fully swell for 2...

Abstract

The invention discloses a hydrogel gasket material for dentures and a preparation method thereof. After palm fiber is treated, modification is conducted by using longan seed and urticae radix leachingliquid, so that the palm fiber is soft and has toughness, the tensile strength of the hydrogel material is improved, the service life of the hydrogel material is prolonged, the prepared hydrogel haseffects of stopping bleeding, relieving pain and reducing inflammation, and improving the symptoms such as gingivitis, periodontal swelling, bleeding and the like caused by gaps between dentures and gums, loosening and friction, the dentures are fixed, and the chewing efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of denture soft lining materials, and in particular relates to a denture hydrogel spacer material and a preparation method thereof. Background technique [0002] Immediate restoration of complete dentures can maintain the patient's facial aesthetics, language and chewing functions, and relieve the patient from the pain of missing teeth. However, within a period of time when the immediate denture is worn, due to the rapid absorption of the alveolar bone after tooth extraction, a gap will appear between the denture base and the supporting tissue, resulting in denture looseness and tenderness. Adhesive spacers can improve the satisfaction rate of denture use, improve the chewing function of dentures, and obtain better clinical results. However, the existing denture spacers have single functions and poor comfort, which can easily cause symptoms such as gingivitis, periodontal swelling, and bleeding, which bring...
