Description

Technical Field

[0001] The utility model relates to the technical field of porcelain furnaces, in particular to a porcelain furnace for processing dentures. Background Art

[0002] Dentures are what people often call "false teeth". In medicine, it is a general term for any restoration made after partial or complete loss of upper or lower teeth. In the processing of dentures, a dental porcelain furnace is required to perform a porcelain operation once.

[0003] When porcelain baking dentures, the operator needs to open the porcelain baking furnace, place the denture on the tray, and then close the furnace to perform the porcelain baking operation. However, if the denture is placed directly on the tray, it is difficult to fix the denture. The denture may shake or shift during the porcelain baking process, which reduces the porcelain baking effect and processing quality of the denture. After the porcelain baking is completed, the operator needs to remove the denture from the high-temperature tray. Moreover, when the high-temperature furnace is opened, the operator's hands are above the tray. The operator's hands are very likely to touch the furnace and get burned, which is very dangerous.
