Problems solved by technology

[0003] However, existing coatings are formed on dentures by ion spraying technology using hydroxyapatite bioceramic material as the main component. Because the coating prepared by this method has poor bonding with dentures, it is easy to peel off and has a short lifespan.

Abstract

The invention discloses a method for preparing a denture film layer. The film layer comprises a base layer, a first transition layer, a second transition layer and a surface layer; the preparation method comprises the following steps: 1) taking powdery nano-hydroxyapatite , graphene and zirconia as raw materials; 2) use nano-hydroxyapatite as the base layer coating, and reserve; mix nano-hydroxyapatite and zirconia evenly as the first transition layer coating, and reserve; Limestone, zirconium dioxide and graphene are mixed uniformly as the second transition layer coating for later use; after mixing zirconium dioxide and graphene uniformly as the top coat for later use; A graphene-zirconia-nanometer hydroxyapatite gradient composite film layer is formed. The invention can accurately control the metallurgical bonding of each coating, solve the peeling problem of the coating, and form gradients among the coatings sequentially, reduce the generation of thermal stress, and can greatly improve the service life of the denture film layer.

Description

technical field [0001] The invention relates to the field of dentures, in particular to a method for preparing a denture film layer. Background technique [0002] In recent years, the application value of hydroxyapatite bioceramic materials has been continuously developed, and its own defects such as poor mechanical properties, low self-strength, and insufficient toughness are gradually exposed, which limits the wide application of hydroxyapatite bioceramic materials. , It is difficult to meet the medical requirements. How to obtain the perfect combination of mechanical properties, biocompatibility and material life of hydroxyapatite bioceramics is a question discussed by material scientists. Hydroxyapatite bioceramic materials have made great progress in the research of artificial tooth roots, jaws, and bone filling materials, and have been gradually put into clinical application with success. However, the application of hydroxyapatite bioceramics is limited due to its lo...
