Description

Technical Field

[0001] The utility model relates to the technical field of automatic processing of artificial teeth, in particular to a combined bionic 3D printing zirconia artificial teeth manufacturing device. Background Art

[0002] Traditional tooth defect repair is often based on manual repair, which is inefficient and prone to errors in handmade dentures. In recent years, digital oral restoration technology has gradually come into people's view. Zirconia, as a common denture material used in digital oral restoration, has better biocompatibility than metals and alloys, is non-irritating and non-corrosive to the gums, has a natural color and is light-transmitting. It is currently widely used in oral denture repair.

[0003] For example, the publication number CN209091680U is "A device for 3D printing zirconia dentures", in which a horizontal workbench, a horizontal moving mechanism, a molding cylinder, a molding cylinder lifting mechanism, a slurry cylinder and a laser galvanometer system are provided. The horizontal moving mechanism is arranged on the horizontal workbench, and the slurry cylinder moves along the horizontal moving mechanism, and zirconia slurry is supplied to the molding cylinder. The laser galvanometer system emits laser to photo-cure the slurry in the molding cylinder to form a cross-sectional layer film of a personalized denture; the photo-curing operation of supplying zirconia slurry and the laser galvanometer system is repeated to form a personalized denture embryo layer by layer, and then the embryo is post-processed to obtain a finished zirconia denture. The zirconia denture is additively manufactured using 3D printing technology, which reduces the process of traditional machining of zirconia dentures, shortens the machining cycle, and is not limited by the inability of the tool to reach certain surfaces in traditional machining. Zirconia dentures with complex shapes or multiple units can be processed, significantly improving printing efficiency.

[0004] Although the above-mentioned printing device has certain advantages in the processing and production of zirconia dentures, it still has certain disadvantages:

[0005] When using the above device, when the zirconium oxide powder is solidified into a zirconium oxide block, it is easy to stick to the mold, making it difficult to take out the zirconium oxide block, thereby affecting work efficiency. At the same time, when performing 3D printing, waste chips are easy to be generated. If the device is not protected, the waste chips are easy to fly around, making it difficult to clean up.
