Abstract

The invention discloses a strong-radiation-resistance fiber pile and a preparation process thereof, and relates to the technical field of dental repair materials. The anti-radiation fiber pile is prepared from the following raw materials in parts by weight: modified fibers and resin preparation liquid, wherein the modified fiber is prepared from SiO2, Al2O3, B2O3, a modifier containing a radiation-resistant component and CaO; and the resin preparation liquid comprises epoxy resin, a curing agent and an accelerant. The fiber pile has X-ray radiation resistance and can be uniformly developed, sothat the fiber pile can be quickly and accurately distinguished. The preparation method comprises the following steps: firstly, sequentially carding, drying, infiltrating, pulling, extruding, and molding a plurality of bundles of modified fibers according to production procedures to prepare a bar; and then subjecting the bar to rounding, machining, forming, ball milling, cleaning, and drying to prepare the radiation-resistance fiber pile. The disclosed preparation method has the advantages that the time is saved and the production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of dental restorative materials, more specifically, it relates to a strong anti-radiation fiber post and its preparation process. Background technique [0002] When there is a large-area tooth defect caused by dental caries or trauma, because the remaining tooth tissue is relatively weak, if there is no filling support, the tooth will easily break or fall off. At the beginning, people’s solution was to use metal posts to strengthen the retained teeth, but the metal posts are generally easily corroded by liquids such as saliva in the mouth and dentinal tubules, which in turn causes discoloration of the teeth and restorations and loosening of the retention posts. The repair time is very short and the repair effect is not ideal. With the development of technology, fiber posts are used clinically instead of metal posts. When using fiber posts to fix teeth, in order to save time, fiber posts usually use pre-made...
