Problems solved by technology

The main advantage of hard plastic is that it has sufficient hardness and strength, and is easy to shape; its main disadvantage is that the process is complicated, requires specific processing facilities, and irritating odors are generated during processing
Rigid plastics cannot degrade by themselves under natural conditions, which can easily cause environmental pollution and make it difficult to dispose of waste
After searching, no application of superhard gypsum in preparing simulated human alveolar bone is disclosed or used

Embodiment Construction

[0026] (1) Making alveolar bone silicone rubber impression

[0027] ①Fix the hard plastic model of the alveolar bone in the center of the base of the model box;

[0028] ②Mix components A and B of silicone rubber for complex molding in a 1:1 mass ratio on a vacuum mixer for 50 or 55 or 60 seconds;

[0029] ③ Slowly inject silicone rubber into the model box on the vibrating machine until the hard plastic model is completely submerged;

[0030] ④ solidify at room temperature for 30 minutes;

[0031] ⑤ Pull out the plastic model and trim the shape.

[0032] (2) Manufacture of superhard plaster alveolar bone model

[0033] ① Put the super-hard gypsum powder according to the water-powder ratio: 7ml: 30g, slowly add the powder into tap water in a rubber bowl to make a paste;

[0034] ②Pour the paste into the alveolar bone impression made according to a certain shape and requirements, and vibrate while adding the paste to remove the air bubbles in the paste, so as not to affect t...

Description

technical field [0001] The invention relates to the field of stomatology teaching models, and more specifically relates to the application of superhard gypsum in preparing simulated human alveolar bones for teaching and operation training of stomatology. Background technique [0002] At present, hard plastic is mostly used to simulate alveolar bone at home and abroad. The main advantage of rigid plastic is that it has sufficient hardness and strength and is easy to shape; its main disadvantage is that the process is complicated, special processing facilities are required, and pungent odors are generated during processing. Rigid plastics cannot degrade by themselves under natural conditions, which can easily cause environmental pollution and make it difficult to dispose of waste. The application of superhard gypsum in preparing simulated human alveolar bone has not been disclosed or used after searching. Contents of the i...
