Problems solved by technology

However, in the existing oral preparations, the active ingredient is difficult to attach to the lesion, the onset speed is slow, and the pertinence is poor, which makes it difficult for gingivitis patients to relieve pain immediately; and the medication site is in the oral cavity, and the patient is easy to swallow the preparation together with saliva. The poor taste of the medicine makes the patients feel bad when using the medicine, and they are unwilling to accept long-term use, making it difficult to achieve the required course of treatment and curative effect; at the same time, it is difficult for the active ingredients to adhere to the lesion for a long time, so that the patients need to frequently supplement the medicine , It also makes it difficult for patients to adhere to the use of drugs, making gingivitis repeated and difficult to completely heal

Abstract

The invention discloses a preparation method of analgesic bioactive glass powder, which is prepared by reacting raw materials such as concentrated nitric acid, ethyl orthosilicate, triethyl phosphate, calcium nitrate tetrahydrate, sodium nitrate, potassium nitrate, potassium-containing compound aqueous solution and the like. . The invention also discloses the application of an analgesic bioactive glass powder, which is applied to oral preparations. The analgesic bioactive glass powder prepared by the invention has good effects of resisting tooth sensitivity and relieving tooth pain, and is especially suitable for targeted treatment of bleeding gums and tooth pain. Potassium ions are slowly released after the bioactive glass powder degrades the dentinal tubules, blocking the nerve transmission in the dentinal tubules and immediately reducing tooth pain; while the bioactive glass has long-term anti-sensitivity effects on teeth, the two complement each other and can be effective It can effectively relieve tooth sensitivity and pain, and the effect can be seen after 3 months of continuous use, which can effectively prevent repeated attacks of gingivitis.

Description

technical field [0001] The invention relates to the technical field of bioactive glass preparation, in particular to a preparation method and application of analgesic bioactive glass powder. Background technique [0002] Biomaterials are a class of high-tech materials, mainly used in the diagnosis and repair of human tissues or organs. The first generation of biomaterials has no biological activity, such as medical metals, inert ceramics, etc., which are biologically inert materials; the second generation of biomaterials, such as bioactive ceramics, hydroxyapatite, etc., can provide tissue conduction for newborn tissues The ability, that is, tissue-conducting biomaterials, has biological activity; in the 1990s, the concept of third-generation biomaterials was proposed, which stimulated cell responses at the molecular level, and belonged to tissue-inducing biomaterials. This kind of material is bioactive and degradable, and at the same time, it has gene activation function, ...
