Customized fixed false tooth porcelain baking process

Abstract

The invention discloses a customized fixed false tooth porcelain baking process which comprises the following steps: step 1, metal turning and polishing; step 2, magnetic cleaning; step 3, spraying porcelain; step 4, high-temperature porcelain baking; step 5, porcelain turning and polishing; step 6, spraying and glazing; step 7, freezing and polishing; According to the invention, a sand blasting polisher is used for replacing a traditional manual polishing instrument, so that surface defects such as burrs and flashes on the metal false tooth blank are thoroughly removed, the problem of porcelain layer fracture of the false tooth in the use process is avoided, the working reliability of the false tooth is improved, the processing time of the false tooth is shortened, the production efficiency of the false tooth is improved, a cleaning solution formed by mixing distilled water, acetone, ethylene glycol and citric acid is matched with a magnetic stirrer to clean the metal false tooth blank, so that impurities such as scrap iron and oil stains on the metal false tooth blank in the processing process are thoroughly removed, the bonding strength of the porcelain powder is improved, and the porcelain baking effect of false teeth is ensured.

Description

technical field [0001] The invention relates to the technical field of denture production, in particular to a custom-made fixed denture ceramic technology. 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 removed and worn by patients themselves, while removable dentures can be easily removed and worn by patients. Fixed dentures, using the healthy teeth on both sides of the missing teeth as support, fix the dentures in the mouth, suitable for a small number of missing teeth, intermittent missing teeth, and good health of the remaining teeth. At present, the production of tra...

Problems solved by technology

[0003] However, most of the traditional custom-made fixed denture porcelain processes have the following problems: First, it is difficult to remove surface defects such as burrs and flashes on the metal denture body through manual grinding equipment, which causes the denture to be damaged during use. The cracking of the porcelain layer is prone to occur in the process, which affects the working reliability of the denture; second, the cleaning of the polished metal denture body is insufficient, and it is impossible to completely remove impurities such as iron filings and oil stains contaminated during processing, which reduces the quality of the porcelain powder. Third, the glazed denture body is polished by manual polishing equipment, the polishing effect is poor, the processing time is long, and it is difficult to remove the remaining burrs and fly Surface defects such as edges are cleaned up, which affects the precision of denture manufacturing
