Problems solved by technology

Moreover, the fiber post can achieve a high bonding strength between the resin adhesive and the root canal dentin, which can prolong the service life of the restoration and reduce the occurrence of root fractures, which is beneficial to the preservation and failure of the tooth. Afterwards, it will be repaired; but at present, most of the foreign technical barriers need to be imported, and the price is relatively expensive

Abstract

The invention relates to a medical tooth root post composite material. The medical tooth root post composite material comprises unsaturated polyester resin, curing agents, accelerant, quartz fibers and heat discoloration powder. The components are mixed in proportion, placed into an extruder and extruded in a stick-like mode at the temperature ranging from 80 DEG C to 120 DEG C. Cutting and packaging are conducted according to the size of required tooth root posts. The tooth root post composite material fills the blank in China and reaches the international advanced level, and the bending strength of a formed fiber post reaches 600 mpa. The composite material is good in elasticity modulus, light, high in strength, good in color and luster, superior in tooth repair, wide in application range, quick and easy to operate and suitable for repairing a dental crown with large-area missing, the fixing position of a fixed partial denture, detorted teeth, malposed teeth or rotated teeth and the like, has strong market competitiveness and wide market prospects, and the frequency of return visits of a patient is reduced.

Description

technical field [0001] The invention relates to a medical polymer material, in particular to a medical tooth root post composite material. Background technique [0002] We wear braces on the teeth that have been treated. Generally, a post needs to be placed in the root of the tooth, so that it can be stronger after wearing porcelain or other materials. We all know that the post and core are like the foundation of porcelain teeth, and the foundation is very important. Therefore, only by choosing a suitable post and core can a good restoration effect and use effect be achieved. There are many types of post cores, and the materials of the root posts currently used are metal posts and fiber post; the main component of ordinary metal posts is nickel-chromium alloy or cobalt-chromium alloy, which is relatively hard, and the post core itself is very strong, but it is very easy to cause Root splitting, easy to corrode, poor biocompatibility, choose carefully.
