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
The present invention relates to the manufacturing materials of basal seat area and the manufacturing approach of base, the manufacture method of particularly a kind of argentiferous ion base material and argentiferous ion base.
Background technology
Because making the tooth resin all is the complex environment that contacts for a long time in the oral cavity with soft cushioning material, various bacteria and fungus are often adhered in its surface, can produce bacterial plaque and denture stomatitis, and it is healthy to influence serviceability and user, cause the pathological changes states such as atrophy of oral cavity tissue.And existing degerming mode brings inconvenience to user, and is not can both produce good effect at all situations.Part degerming mode for example uses modes such as oxidisability disinfectant, ultraviolet disinfection to produce destruction to making tooth resin and soft cushioning material, shortens its service life, the money and the time of waste user.And silver ion has broad-spectrum sterilization and suppress vegetative effect, moderate cost, and base do not had destruction.
But because the nanometer silver application time is not long, its hazardness that possibly exist is still in further discussing.Also there are following 2 deficiencies in the application of silver ion in dental material.
Preliminary study shows: being widely used of nanometer silver possibly cause serious harm to human health and environment, possibly cause forming antibacterial antibody, and its usefulness is reduced.2009 an international research (EMERGNANO) looked back the toxigenous evidence of present whole world research nano-particle, report refers to have ample evidence to show that silver nano-grain maybe be harmful to environment, therefore should use this material in line with the prevention principle.Silver ion has environmental disruption property, when extremely low concentration, aquatile is also had extremely strong toxicity.Because the silver that discharges in the medical device product is especially dangerous because of getting into water body.And silver ion is released in the waste water in the production process, finally gets into the municipal sewage plant, and then has limited sewage treatment plant's beneficial microorganism growth.
Secondly; Silver ion adds the blackout situation that can produce material in the base material with the form of simple substance silver; And carriers such as the zeolite of silver ion through not advancing special handling, zirconium phosphate are added to and can produce the problem that color changes in the base material, so the change of optical property also is a great deficiency.
Summary of the invention
