Problems solved by technology

What's more serious is that a large number of air bubbles and hard lumps are produced, which are difficult to remove, which leads to coarse spots and strong stains on the hardened material
Also, due to their hardness, these materials are brittle and break easily

Abstract

The invention provides a composition for preparing dental temporary crown bridge. The composition is prepared from a matrix component and a catalytic component, wherein the matrix component is prepared from 40-60 parts by weight of acrylate monomer, 1-10 parts by weight of organosilicon modified acrylate, 0.5-1 part by weight of self-curing accelerator and 40-50 parts by weight of filler; the catalytic component is prepared from 40-60 parts by weight of acrylate monomer, 1-10 parts by weight of organosilicon modified acrylate, 1-2 parts by weight of self-curing initiator and 40-50 parts by weight of filler. The composition for preparing the dental temporary crown bridge is prepared by means of cooperation of the acrylate monomer and the organosilicon modified acrylate and in combination ofa self-curing reaction of the curing accelerator, the filter and the curing initiator. The composition for preparing the dental temporary crown bridge is rapid in curing speed, high in strength and good in toughness, and also has the characteristic of being low in oxygen inhibition layer.

Description

technical field [0001] The invention relates to the technical field of materials, in particular to a composition for making dental temporary crowns and bridges and a preparation method thereof. Background technique [0002] A temporary crown, also known as a temporary crown, is a temporary full crown that is temporarily bonded in the patient's mouth after the preparation of the tooth for crown restoration and before the completion of the final crown restoration, and the patient cannot freely wear it. [0003] Traditional temporary crown materials consist of liquid / powder mixtures mixed together. The liquid in this combination consists essentially of a monofunctional monomer (such as methyl methacrylate) and an activator; the powder consists of a polymer (polymethyl methacrylate) and a catalyst. Systems of this type are easy to manipulate and they produce crowns and bridges that are significantly resistant to fracture. However, the aforementioned liquids are problematic. T...
