Description

Technical Field

[0001] The invention relates to a jaw frame, and in particular to an integrated injection-molded denture jaw frame and a use method thereof. Background Art

[0002] It is inevitable that teeth will be damaged. When problems occur with teeth, they must be repaired in time. There are many people who choose dentures. At present, when making dentures, most of them are made by doctors using dental tray impression materials to take molds, and then the dental tray impressions are sent to the factory to process the dentures. After the factory receives the model, it is necessary to fill the antagonist dental tray impression with fluid plaster. After the fluid plaster cools down, take out the antagonist plaster dental mold, and then grind the excess plaster on the buccal and lingual sides of the antagonist plaster dental mold, and then punch holes in the bottom to install the fixing nail group, and then apply a layer of plaster separator on the bottom of the antagonist plaster dental mold, and then pour fluid plaster into the base mold sleeve, and insert the antagonist plaster dental mold with the fixing nail group into the fluid plaster, and then wait for the fluid plaster in the base mold sleeve to cool down, and then Finally, the antagonist base is ground and repaired, and then the antagonist plaster dental model is installed back to the antagonist base; the main jaw model dental tray also needs to repeat the above steps, but the difference is that after grinding and repairing the main jaw base, the denture part of the main jaw plaster dental model needs to be sawed off from the plaster main jaw model with a saw, and then the cervical margin line of the denture tooth position is modified, and then they are put back into the main jaw base together, and then the main jaw base and the antagonist base are connected through the connecting arm, and the occlusal relationship is checked. After confirming that there is no problem, they are fixed with glue.

[0003] In summary, the overall process of making dentures is currently rather complicated, and the base also needs to be filled and waited for cooling, which affects the production efficiency. A separation agent needs to be applied between the plaster dental mold and the base.
