A kind of base material containing silver ion and the preparation method of base base containing silver ion

Abstract

The invention relates to a base plate material containing silver ions, and a preparation method of base plate. The method comprises steps that: a basic base plate is manufactured by using a common base plate material containing no silver ion and dental base acrylic resin liquid; the tissue surface of the basic base plate is burnished, such that materials with a thickness of 2mm are removed. The base plate material containing silver ions and dental base acrylic resin liquid are covered on the burnished tissue surface, and compression molding and heating are carried out again, such that a base plate layer containing silver ions with a thickness of 2mm is produced. The base plate material containing silver ions is prepared from materials of, by weight: 0.05 to 1 part of an antibacterial agent, 51 to 59 parts of base plate powder, and 41 to 49 parts of the dental base acrylic resin liquid. With the technical scheme provided by the invention, application security of the material is improved, and optical property of the material is not changed.

Description

technical field [0001] The invention relates to a material for making a denture base and a method for manufacturing the base, in particular to a base material containing silver ions and a method for manufacturing the base containing silver ions. Background technique [0002] Dental resin and soft liner materials are long-term contact with the complex environment in the oral cavity, and a variety of bacteria and fungi often adhere to the surface, which will cause plaque and denture stomatitis, affect the performance of the user and the health of the user, and cause oral tissue damage. Atrophy and other disease states. However, the existing sterilization methods cause inconvenience to users, and not all of them can produce good results. Some sterilization methods, such as the use of oxidizing disinfectants and ultraviolet disinfection, will cause damage to dental resin and soft lining materials, shorten their service life, and waste users' money and time. Silver ions have th...

Problems solved by technology

Silver released from medical device products is especially dangerous due to its potential to enter water bodies

During the production process, silver ions are released into the wastewater, which eventually enters the urban sewage treatment plant, thereby limiting the growth of beneficial microorganisms in the sewage treatment plant.

[0005] Secondly, the addition of silver ions to the base material in the form of simple silver will cause blackening of the material, and the addition of silver ions to the base material through carriers such as zeolite and zirconium phosphate that have not been specially treated will cause color changes. , so the change in optical properties is also a major shortcoming
