Problems solved by technology

[0002] At present, there are many kinds of periodontal disease models used in the teaching of stomatology students. These models are mostly made of rubber or hard plastic, and each model has only one function or is only suitable for training one kind of clinical operation. Moreover, these Most of the models are complex in process, with limited output and market demand, so the cost is high and expensive, which is not conducive to popularization and application
Under natural conditions, rubber or hard plastic cannot be degraded into non-polluted substances, which may easily cause environmental pollution
No method for preparing a multifunctional periodontal disease teaching model has been disclosed or used after searching

Embodiment Construction

[0030] (1) The hard plastic model of periodontal disease is fixed in the center of the base of the model box;

[0031] (2) Mix components A and B of silicone rubber for complex molding on a vacuum mixer in a mass ratio of 1:1 for 60 seconds;

[0032] (3) Slowly inject silicone rubber into the model box on the vibrating machine until the hard plastic model is completely submerged;

[0033] (4) Solidify at room temperature (25°C) for 30 minutes;

[0034] (5) Remove the hard plastic model and trim the shape of the silicone rubber impression;

[0035] (6) Soak the collected isolated teeth in 10% formalin solution for 48 hours, and dry them for 24-48 hours;

[0036] (7) Prepare a mesial-distal circular hole with a diameter of 2 mm in the 1 / 3 area of ​​the root tip of the isolated tooth;

[0037] (8) Connect the roots of loose teeth to be prepared in series with stainless steel wires with a diameter of 1 mm;

[0038] (9) The isolated tooth is placed upside down in the prepared s...

Abstract

The invention discloses a multifunction periodontal disease teaching model. Its preparing steps: 1. fixing the model in the center of model box. 2. Mixing silicone rubber A, B components in vacuum stirrer, 3. Filling silicon rubber in model box; 4. Hardening at room temperature, 5. removing plastic model, 6. immersing the off body tooth in formal formalin liquor; 7. preparing a round aperture on the off body tooth apex; 8, connecting the teeth in series with stainless steel wire, 9, the off body tooth is placed in the die upside down; 10, enclosing the tooth groove with wax piece; 11, modulates it into thick agent with water; 12. the paste is poured into the plaster groove bone module; 13. it is solidified at room temperature, 14. the plaster model is removed after the temperature is cooled to room temperature; 15. drills aperture on the module bottom base and assembles with screw cap; 16, the module is fixed on the head module. The invention is cheap, and simple.

Description

technical field [0001] The invention relates to the field of oral medicine teaching models, and more particularly to a preparation method of a multifunctional periodontal disease teaching model. Background technique [0002] At present, there are many kinds of periodontal disease models used for the teaching of stomatology students. These models are mostly made of rubber or hard plastic, and each model has only one function or is only suitable for training one kind of clinical operation. Moreover, these Most of the models are complicated in technology, limited in output and market demand, so the cost is high and expensive, which is not conducive to popularization and application. Under natural conditions, rubber or hard plastic cannot be degraded into pollution-free substances, which may easily cause environmental pollution. A method for preparing a multifunctional periodontal disease teaching model has not been disclosed or used after searching. ...
