Description

Technical Field

[0001] The utility model relates to the technical field, in particular to a dental bridge auxiliary molding device. Background Art

[0002] When making a dental bridge, first, the dental bridge is designed using computer-aided design (CAD) software based on the patient's oral model and the doctor's design. This step needs to consider factors such as the shape, size, color of the teeth and the degree of matching with the surrounding teeth. Then, the designed dental bridge model is converted into a physical model through computer-aided manufacturing (CAM) equipment. After the design is completed, the dental bridge can be manufactured using computer-aided manufacturing (CAM) technology and 3D printing to complete the production of the dental bridge. This step greatly improves the speed and accuracy of dental bridge manufacturing, while also reducing costs.

[0003] Existing materials for dental bridges usually include metals (such as gold alloys), porcelain, resins, etc. A metal 3D printer is required to print metal dental bridges. When in use, metal powder is placed on the workbench inside the printer, and then the printer emits a laser beam to melt the metal powder layer by layer, stacking layer by layer to form the final printed object. After printing is completed, since metal 3D printing involves high-temperature operations, the heat distribution during the entire printing process is difficult to control, resulting in some metal powders not being completely melted and eventually remaining in the finished product. These residual metal powders then need to be cleaned. Since the existing equipment does not have a cleaning structure inside, the operator needs to use manual brushes and other tools to clean them, which is too troublesome and reduces the efficiency of the next processing.
