Problems solved by technology

[0003] Adding inorganic fillers will increase the rigidity of the material, but it will reduce its elastic modulus and flexural strength. The key to solving this contradiction is to try to choose suitable inorganic fillers or modify the inorganic fillers, and optimize the properties of modified substances and inorganic fillers. Types of inorganic fillers. At present, a single factor is used to modify a single type of inorganic filler, and compound modification often causes antagonism. Therefore, it is necessary to find an inorganic filler that can be compounded and modified to improve the rigidity of oral denture materials without reducing its elasticity. Modulus and flexural strength, is a problem to be solved urgently in this field

Abstract

The invention discloses an oral denture material and a preparation method thereof. The oral denture material is made of zirconia and aluminum oxide dispersed and modified by polymethyl methacrylate. The oral denture material of the present invention adopts modified modified zirconia and alumina as inorganic fillers, and while retaining the rigidity of the material, does not reduce its elastic modulus and flexural strength, and adopts γ-glycidyl ether oxypropyl Trimethoxysilane and N‑β‑(aminoethyl)‑γ‑aminopropyltrimethoxysilane are mixed modifiers with synergistic effect.

Description

technical field [0001] The invention belongs to the technical field of medical material preparation, and in particular relates to an oral denture material and a preparation method thereof. Background technique [0002] The development of stomatology depends on the development of materials science. Finding better oral materials has been the direction of many dental workers' efforts for many years. Dental nanocomposite is a dental restorative material composed of a resin matrix, a surface-treated inorganic filler, and an initiating system. Organic polymer is the main part of the material, which is a continuous distribution of high molecular organisms. The main function is to adhere the various components of the composite material together, giving it plasticity, curability and certain strength. It is the most commonly used restorative resin material in dentistry. Inorganic fillers in composite materials include nano-calcium carbonate, nano-silicon dioxide, nano-titanium diox...
