Problems solved by technology

[0004] When wearing a complete denture, the base will fit closely with the denture, and there is less saliva in the joint, making this area easy to become a breeding ground for bacteria, fungi and other microorganisms. Food residues will provide nutrients for microorganisms, making it easy to form plaque on dentures, reducing the service life of dentures; for the elderly with poor resistance, oral inflammation and other diseases are more likely to occur; and patients are using new dentures. When wearing dentures, it is necessary to have a certain running-in period with the dentures to gradually overcome the discomfort. Compared with the elderly, their physique is weaker and their oral environment is poor. When wearing new dentures, they may even experience nausea and vomiting. Therefore, the number of denture replacements for the elderly should be reduced as much as possible; and during the production process of the base of traditional dentures, due to the internal stress of the heat treatment of the base, tiny cracks or cracks will occur inside and on the surface of the base. The back denture is easy to break, reducing its service life; therefore, if a complete denture with excellent antibacterial properties and long service life is made, it is a problem that needs to be solved

preparation example 1

[0037] Preparation example 1: ① Take 20kg of silicon dioxide, 1kg of titanium dioxide and 0.6kg of zirconium dioxide, grind them, place them at a temperature of 900°C, and calcinate them for 4 hours. After cooling, a calcined material is obtained;

[0038] ②Take 0.2kg of silver nitrate powder, add 30kg of water to it, and stir evenly to obtain a silver nitrate solution; add 2kg of calcined material to the silver nitrate solution, and stir at a temperature of 20-30°C for 10 minutes to obtain a mixed solution;

[0039] ③Add 0.2kg of glucose and 1kg of 10wt% sodium hydroxide aqueous solution to the mixed solution, stir for 10min, filter with suction, then wash with 50wt% ethanol solution, and dry at 80°C for 6h to obtain silver-loaded silica.

preparation example 2

[0040] Preparation Example 2: ① Take 25kg of silicon dioxide, 1.5kg of titanium dioxide and 0.8kg of zirconium dioxide, grind them, place them at a temperature of 925°C, and calcinate them for 5 hours. After cooling, a calcined material is obtained;

[0041] ②Take 0.25 kg of silver nitrate powder, add 30 kg of water to it, and stir evenly to obtain a silver nitrate solution; add 3 kg of calcined material to the silver nitrate solution, and stir for 15 minutes at a temperature of 25°C to obtain a mixed solution;

[0042] ③Add 0.3kg of glucose and 1.5kg of 10wt% sodium hydroxide aqueous solution to the mixed solution, stir for 15min, filter with suction, then wash with 50wt% ethanol solution, and dry at 85°C for 7h to obtain the Silver silica.

preparation example 3

[0043]Preparation example 3: ① Take 30kg of silicon dioxide, 2kg of titanium dioxide and 1kg of zirconium dioxide, grind them, place them at a temperature of 950°C, and calcinate them for 6 hours. After cooling, a calcined material is obtained;

[0044] ② Take 0.3 kg of silver nitrate powder, add 30 kg of water to it, and stir evenly to obtain a silver nitrate solution; add 4 kg of calcined material to the silver nitrate solution, and stir for 20 minutes at a temperature of 30°C to obtain a mixed solution;

[0045] ③Add 0.4kg of glucose and 2kg of 10wt% sodium hydroxide aqueous solution to the mixed solution, stir for 20min, filter with suction, then wash with 50wt% ethanol solution, and dry at 90°C for 8h to obtain silver-loaded silica.

Abstract

The invention discloses an anti-antibacterial complete denture and a preparation method thereof. The anti-antibacterial complete denture comprises artificial teeth and a base plate, the base plate isprepared from the following components in parts by weight: 70-80 parts of dental base acrylic resin powder, 30-40 parts of dental base acrylic resin liquid, 2-3 parts of a silicon flexibilizer, 4-8 parts of silver-loaded silicon dioxide, 2-4 parts of a natural antibacterial agent, and 1-2 parts of nanometer titania. According to anti-antibacterial complete denture and the preparation method thereof, the silver-loaded silicon dioxide, the nanometer titania and the natural antibacterial agent are compound, thus the base plate has the excellent antibacterial performance, the base plate is compound with the silicon flexibilizer, thus the tenacity of the base plate is further improved, and the service life of the base plate is prolonged.

Description

technical field [0001] The invention relates to the technical field of denture materials, more specifically, it relates to an antibacterial complete denture and a manufacturing method thereof. Background technique [0002] Dentures are often referred to as "dentures". In medicine, it is a general term for restorations made after partial or complete loss of upper and lower teeth; complete dentures are a routine restoration treatment for edentulous patients. A complete denture is a removable denture restoration that uses artificial materials to replace the complete missing maxillary or mandibular dentition and related tissues. Adsorption force and atmospheric pressure generated by fitting and edge sealing make the denture adsorb on the upper and lower alveolar ridges, restore the patient's defective tissue and facial appearance, restore chewing and pronunciation functions, and the mucous periosteum and bone tissue covered by the denture base Bears the occlusal pressure of the...
