Description

Technical Field

[0001] This utility model relates to the field of dental prosthesis manufacturing technology, and in particular to a combined biomimetic 3D printing zirconia dental prosthesis manufacturing device. Background Technology

[0002] With the accelerating aging of the global population, tooth loss among the elderly is becoming increasingly common, leading to a continuous rise in demand for dentures. The younger generation is also placing greater emphasis on oral health and aesthetics, no longer satisfied with just the basic functions of dentures but also demanding higher standards in terms of aesthetics and comfort. Zirconia dentures, with their color and texture closely resembling natural teeth, can meet this consumer trend. Furthermore, continuous advancements in oral medical technology have greatly improved the precision and efficiency of zirconia denture manufacturing, making personalized custom dentures possible and further driving the development of the zirconia denture market.

[0003] A search revealed Chinese Patent Publication No. CN222426282U, which discloses a worktable, molding block, guide rail, storage box, rolling galvanometer device, and printing device. This utility model incorporates an integration device and a protective device. By pulling a lever, a limiting block is moved, releasing the limiting block's restriction effect and allowing the left mold to be separated from the mold, thus removing the zirconia block. This design enables rapid mold disassembly without damaging the zirconia block. A protective box intercepts and collects the printing debris, ensuring a clean worktable and improving efficiency. However, this structure generates a large amount of material debris during cutting, resulting in poor economic efficiency. Existing zirconia printing equipment often uses a single printhead structure, which cannot simultaneously achieve high precision and high efficiency. Utility Model Content
