Problems solved by technology

Fixed dentures (commonly known as "fixed dentures") cannot be taken and worn by patients themselves. Due to the long-term use of dentures in the oral environment, the requirements for their corrosion resistance, biocompatibility and antibacterial properties are very high. In the prior art, denture manufacturing Complex, expensive, and its corrosion resistance, biocompatibility and antibacterial properties have not reached the expected level, which limits the service life of dentures

Abstract

The invention discloses a medical denture. The denture is prepared through the steps of carrying out titanium alloy smelting, carrying out atomizing for powder preparation, carrying out powder sintering, carrying out micro-arc oxidation on a surface and carrying out ion implantation. The formation speed of a porous structure is increased in the micro-arc oxidation process through a micro-arc oxidation solution, and harmful substances to the human body are not introduced; and the plasma is injected into the porous material so that the bacteria-microorganism resistance of the porous material canbe improved, and the bacterial reproduction on the surface of the porous material can be effectively inhibited.

Description

technical field [0001] The invention relates to a medical denture and belongs to the technical field of medical instruments. Background technique [0002] Dentures are what people often call "false teeth". Just like "prosthetic legs" and "prosthetic limbs" are called "prosthetic limbs", "dentures" mean teeth that perform "duties" for human beings. In medicine, it is a general term for restorations made after partial or complete loss of upper and lower teeth. There are two types of dentures: removable and fixed. Fixed dentures (commonly known as "fixed dentures") cannot be taken and worn by patients themselves. Due to the long-term use of dentures in the oral environment, the requirements for their corrosion resistance, biocompatibility and antibacterial properties are very high. In the prior art, denture manufacturing It is complex and expensive, and its corrosion resistance, biocompatibility and antibacterial properties have not reached the expected level, which limits t...
