Abstract

The invention discloses a strong anti-reflection fiber post and a preparation process thereof, and relates to the technical field of dental restoration materials. The anti-reflection fiber post is made of raw materials containing the following weights: modified fiber and resin preparation liquid; modified fiber is composed of SiO including SiO 2 , Al 2 O 3 , B 2 O 3 , Modifier and CaO containing radio-blocking components; the resin preparation solution includes epoxy resin, curing agent and accelerator; it has X-ray radio-blocking properties, can be developed uniformly, and can be quickly and accurately distinguished. The preparation method is as follows: firstly, multiple bundles of modified fibers are combed, dried, soaked and pultruded in sequence according to the production process to obtain a bar; then the bar is rounded, machined, formed, ball milled, washed and dried After such treatment, the blocking fiber post can be prepared; the preparation method of the present invention has the advantages of saving time and improving production efficiency.

Description

technical field [0001] The invention relates to the technical field of dental restoration materials, and more particularly, to a strong radiation-resistant fiber post and a preparation process thereof. Background technique [0002] When there is a large-area defect of the tooth caused by caries or trauma, the remaining tooth tissue is relatively weak, and the tooth is easily broken or fallen off if there is no filling to support it. At the beginning, the solution was to use metal posts to enhance the retention of teeth, but metal posts are generally easily corroded by liquids such as saliva and dentinal tubules in the oral cavity, which in turn causes discoloration of teeth and restorations and loosening of 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 sta...
