Problems solved by technology

However, since PMMA is a transparent material, it is necessary to add other materials (such as: quartz glass, ceramics, silicon dioxide, etc.) in clinical practice to meet the different needs of doctors and patients for the transparency of artificial tooth materials. The material components usually have problems such as poor compatibility, which makes the artificial tooth base crack. At the same time, the process is complicated, time-consuming and costly.

Embodiment 1

[0018] Weigh PMMA and PMAA according to the mass ratio of 1:1, dissolve them with 10mL of acetone, the configuration concentration is 0.2g / mL, stir for 24 hours, inject the solution into a 2mL mold, and wait for the acetone to completely volatilize under the condition of ambient humidity of 25%. Preparation of artificial tooth materials (such as figure 1 Shown in A), the light transmittance at 550nm wavelength is about 85.21% ( figure 2 ).

Embodiment 2

[0020] Weigh PMMA and PMAA according to the mass ratio of 1:1, dissolve them with 10mL acetone, the configuration concentration is 0.2g / mL, stir for 24 hours, inject the solution into a 2mL mold, and wait for the acetone to completely volatilize under the condition of ambient humidity of 30%. Preparation of artificial tooth materials (such as figure 1 Shown in B), the light transmittance at 550nm wavelength is about 81.45% ( figure 2 ).

Embodiment 3

[0022] Weigh PMMA and PMAA according to the mass ratio of 1:1, dissolve them with 10mL of acetone, the configuration concentration is 0.2g / mL, stir for 24 hours, inject the solution into a 2mL mold, and wait for the acetone to completely volatilize under the condition of ambient humidity of 35%. Preparation of artificial tooth materials (such as figure 1 Shown in C), the light transmittance at 550nm wavelength is about 80.14% ( figure 2 ).

Abstract

The invention belongs to the technical field of material engineering, and relates to an artificial tooth material with controllable transparency and a preparation method thereof. The preparation method comprises: S1. dissolving polymethyl methacrylate (PMMA) and polymethacrylic acid (PMAA) in acetone solution to obtain a mixed solution; S2. stirring the mixed solution for 24 to 48 hours, Under the condition of a humidity of 25-75%, pour it into a mold, and let it stand until the acetone is completely volatilized to obtain an artificial tooth material. The process is simple and the realization time is short, and the preparation method can obtain artificial tooth materials with different transparency by setting different ambient humidity, and the transparency is still adjustable. The artificial tooth material obtained by the preparation method is not easy to crack because no other components are added.

Description

technical field [0001] The invention belongs to the technical field of material engineering, and relates to an artificial tooth material with controllable transparency and a preparation method thereof. Background technique [0002] At present, the most clinically used artificial tooth material is polymethyl methacrylate (PMMA). This type of material is due to its strong design processability, corrosion resistance, strong resistance to fragmentation, good biocompatibility, and low cost. , Durable and other advantages are very popular among doctors and patients. However, since PMMA is a transparent material, it is necessary to add other materials (such as: quartz glass, ceramics, silicon dioxide, etc.) in clinical practice to meet the different needs of doctors and patients for the transparency of artificial tooth materials. The material components usually have problems such as poor compatibility, which makes the artificial tooth base crack, and at the same time, the process ...
