Description

Technical Field

[0001] The invention relates to the technical field of oral mold preparation, in particular to an oral mold preparation device which is convenient for shoveling and unloading. Background Art

[0002] Oral molds are models of teeth, usually used in stomatology, for oral model tooth plastic surgery, restoration, and other operations. Oral molds are used by doctors to analyze oral model tooth plastic surgery, restoration, and restoration plans. They are usually made by mixing tooth powder and water, like toothpaste, and have a minty taste when bitten. When making oral molds for occlusion, they are divided into upper and lower bites, packed in a plastic box, and put on the teeth with your mouth open. After the bite model is completely dry, it is taken down as a whole, and then other materials are used to make oral molds.

[0003] When molding the oral mold, plaster is usually placed in the impression. However, since the plaster is relatively moist, it cannot fit the impression in a timely and effective manner, and is difficult to remove after the plaster hardens. This causes deviations in the molding of the oral mold, which adversely affects the processing of the oral mold. Summary of the invention
