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 the following steps: s1, dissolving polymethyl methacrylate (PMMA) and polymethacrylic acid (PMAA) in an acetone solution to obtain a mixed solution; s2, stirring the mixed solution for 24-48 hours, injecting the mixed solution into a mold under the condition that the environmental humidity is 25-75%, and standing until the acetone is completely volatilized to obtain the artificial tooth material. The preparation method can obtain the artificial tooth materials with different transparencies by setting different environmental humidities, and the transparencies of the artificial tooth materials are 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
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
Currently, the most clinically used artificial tooth material is polymethyl methacrylate (PMMA), which is a kind of material that is well received by doctors and patients due to its advantages of high processability, corrosion resistance, high fracture resistance, good biocompatibility, low cost, durability and the like. However, since PMMA is a transparent material, different requirements of doctors and patients on the transparency of the artificial tooth material can be clinically met by adding other materials (such as quartz glass, ceramics, silicon dioxide and the like) and matching with a complex processing technology, the added material components usually have the problems of poor compatibility and the like, so that the artificial tooth base is cracked, and meanwhile, the problems of complex process, time consumption, higher cost and the like are solved.
Disclosure of Invention
In view of the above, the present invention provides a transparency-controllable artificial tooth material and a preparation method thereof, wherein the preparation method can prepare the artificial tooth material with a certain transparency by controlling the environmental humidity, and has the advantages of simple process, short required time and difficult cracking.
The invention provides a preparation method of an artificial tooth material with controllable transparency, which comprises the following steps:
s1, dissolving polymethyl methacrylate and polymethacrylic acid in an acetone solution to obtain a mixed solution;
s2, stirring the mixed solution for 24-48 hours, and standing until the acetone is completely volatilized under the condition of 25-75% humidity to obtain the artificial tooth material.
Further, in the above preparation method, in step S1, the mass ratio of the polymethyl methacrylate to the polymethacrylic acid is (0.5 to 2): 1.
further, in the above preparation method, in step S1, the mass ratio of the polymethyl methacrylate to the polymethacrylic acid is 1: 1.
further, in the above preparation method, the total concentration of the polymethyl methacrylate and the polymethacrylic acid in the mixed solution is 0.2 g/mL.
Further, in the above preparation method, in step S2, the humidity condition is 20 to 35%.
The invention also provides the artificial tooth material with controllable transparency prepared by the preparation method.
Compared with the prior art, the artificial tooth material meeting the specific transparency requirement can be obtained by simply mixing polymethyl methacrylate (PMMA) and polymethacrylic acid (PMAA) according to a certain proportion and regulating and controlling the humidity, the preparation process is simple, the required time is short, the compatibility of the polymethyl methacrylate (PMMA) and the polymethacrylic acid (PMAA) is good, and the obtained artificial tooth material is not easy to crack. The artificial tooth material obtained by the present invention can also be changed in transparency by post-treatment.

FIG. 2 is a graph of light transmittance data (wavelength 550nm) for PMMA/PMAA artificial tooth materials prepared at 25%, 30%, 35%, 40%, 45%, 50% ambient humidity.
Detailed Description
The present invention will be further explained with reference to the following examples and the accompanying drawings, which are only illustrative and not intended to limit the scope of the present invention.
The invention adopts a temperature controller customized by Shanghai Taotaceae biotechnology limited company to control the environmental temperature.
Example 1
According to the mass ratio of 1:1 PMMA and PMAA were weighed out and dissolved in 10mL of acetone at a concentration of 0.2g/mL, stirred for 24 hours, and the solution was poured into a 2mL mold and allowed to evaporate completely at 25% ambient humidity to prepare an artificial tooth material (see FIG. 1A) having a light transmittance of about 85.21% at a wavelength of 550nm (FIG. 2).
Example 2
According to the mass ratio of 1:1 PMMA and PMAA were weighed, dissolved in 10mL of acetone at a concentration of 0.2g/mL, stirred for 24 hours, and the solution was poured into a 2mL mold and allowed to evaporate completely at an ambient humidity of 30% to prepare an artificial tooth material (see FIG. 1B) having a light transmittance of about 81.45% at a wavelength of 550nm (see FIG. 2).
Example 3
According to the mass ratio of 1:1 PMMA and PMAA were weighed, dissolved in 10mL of acetone at a concentration of 0.2g/mL, stirred for 24 hours, and the solution was poured into a 2mL mold and allowed to evaporate completely at an ambient humidity of 35% to prepare an artificial tooth material (see FIG. 1C) having a light transmittance of about 80.14% at a wavelength of 550nm (FIG. 2).
Example 4
According to the mass ratio of 1:1 PMMA and PMAA were weighed, dissolved in 10mL of acetone at a concentration of 0.2g/mL, stirred for 24 hours, and the solution was poured into a 2mL mold and allowed to evaporate completely at an ambient humidity of 40% to prepare an artificial tooth material (see FIG. 1D) having a light transmittance of about 0.47% at a wavelength of 550nm (see FIG. 2).
Example 5
According to the mass ratio of 1:1 PMMA and PMAA were weighed, dissolved in 10mL of acetone at a concentration of 0.2g/mL, stirred for 24 hours, and the solution was poured into a 2mL mold and allowed to evaporate completely at 45% ambient humidity to prepare an artificial tooth material (see FIG. 1E) having a light transmittance of about 0.19% at a wavelength of 550nm (FIG. 2).
Example 6
According to the mass ratio of 1:1 PMMA and PMAA were weighed, dissolved in 10mL of acetone at a concentration of 0.2g/mL, stirred for 24 hours, and the solution was poured into a 2mL mold and allowed to evaporate completely at an ambient humidity of 50% to prepare an artificial tooth material (see FIG. 1F) having a light transmittance of about 0.17% at a wavelength of 550nm (see FIG. 2).
Comparative example
According to the mass ratio of 1: 0, weighing PMMA and PMAA, dissolving the PMMA and PMAA with 10mL of acetone, stirring for 24 hours, injecting the solution into a 2mL mould, and preparing the PMMA artificial tooth material after the acetone is completely volatilized under the conditions of the environmental humidity of 25%, 30%, 35%, 40%, 45% and 50%.
From examples 1 to 6 and comparative examples, it can be seen that the transparency of PMMA clear material cannot be changed by humidity, whereas the transparency of PMMA/PMAA artificial tooth material decreases with increasing ambient humidity after modification by PMAA mixing with an acrylic acid source.
Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the invention. Thus, the present invention is not intended to be limited to the embodiments shown herein but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
