Abstract

The present invention relates to a disinfection method of oral artificial tooth, impression and plaster model. Said disinfection method includes the following steps: electrolyzing sodium chloride or potassium chloride solution to produce acidic redox potential water; utilizing ultrasonic oscillation process to atomize the acidic redox potential water to form acidic redox electrolytic vapour saturated space; in said saturated space disinfecting oral artificial tooth, impression and plaster model for 25-90 min, then drying for 30-60 min. so as to complete said disinfection operation.

Description

technical field [0001] The invention relates to a disinfection method for oral dentures, impressions and plaster models. Background technique [0002] The oral cavity is an ecosystem rich in bacteria. Because the oral impression is in direct contact with the patient's saliva or even blood, the plaster model is made from the oral impression and often contains a variety of bacteria in the patient's oral cavity, especially the hepatitis B virus. , Mycobacterium tuberculosis, etc. are extremely harmful to the human body, and the current popular human immunodeficiency virus (HIV) makes this problem more prominent. The operation of the model is directly in contact with the staff, which is very easy to cause cross-infection. The current disinfection technologies can be generally divided into physical disinfection / sterilization and chemical disinfection / sterilization. Among them, electrolyzed water has attracted much attention in recent years due to its low cost, simple equipment, ...
