烤瓷牙龈比色板的初步研制及颜色分析
[Abstract]:Objective: to prepare gingival porcelain colorimetric tablets with different proportions by using gingival porcelain powder and staining agent, and to explore the development of gingival colorimetric plate which can be used in clinical practice. Methods: metal gingival porcelain powder G1~G5 and dyeing agent Akz01~Akz20, were selected and divided into A group, G 2 and Akz01~Akz20 group, G 3 and Akz01~Akz20 group, G 4 and Akz01~Akz20 group, and G 4 and Akz01~Akz20 mixed group as A group, G 2 and Akz01~Akz20 group as B group, G 4 and Akz01~Akz20 as D group, G 3 and Akz01~Akz20 mixed group as C group, and G 4 and Akz01~Akz20 as D group respectively. G5 and Akz01~Akz20 were mixed as group E, weighing by electronic balance, weighing paper, each group containing 21 packs, and then firing the colorimetric sheet on the cast Ni-Cr alloy substrate according to the firing process of porcelain fused with metal full crown, The sintered colorimetric sheet was polished and cleaned by ultrasonic. Finally, the colorimetric value of each color sheet was measured by Vita EasyshadyAdvance4.0 wireless computer colorimetry, and the results were statistically analyzed by SPSS19.0 software. Results: (1) the color distribution of each group was regular. The results are as follows: in group A, group E is in the category of the highest value, while group C is in the category of the lowest. The results showed that group E had the highest brightness, the thickest and brightest color, while group C had the lowest brightness, the faintest color and the darkest color. For saturation C *, the change of group E was the least, while that of group A and D was relatively large. The addition of the sixth chromatin reached the highest value, and then it began to decrease, although it also increased, but the amplitude was relatively small. On the whole, the values of group B are at the maximum value, indicating that the saturation of group B is generally larger than that of the other groups, the farthest away from the center of the center, and has a more brightly colored colorimetric film than the other groups. The change of hue H * value in group A was basically the same as that in group A D after the addition of the same chromatin, which showed that the value of H * increased first and then decreased, and the amplitude was relatively large, while the fluctuation of group E was the least. And the other four groups are far apart. The results showed that group E had the smallest hue and preferred the red direction. (2) the color difference and distribution of the colorimetric plates were different in each group. The main results are as follows: the distribution range of L ~ * value is 10.10 ~ 26.90 ~ (th) C ~ * = 0.50 ~ (14. 20) H ~ * = 0.80 ~ 72.40; The distribution range of E value is 14.60 ~ 27.30. (3) the color range of custom-made colorimetric plate is mostly within the range of natural gingival color, which indicates that the color of custom-made colorimetric plate can basically simulate the color of natural gingival. Conclusion: the customized porcelain gingival colorimetric tablets can extend the clinical application range of the existing gingival porcelain to a certain extent. Compared with the current color values of gingival, it can basically cover the gingival color, but the accuracy of the colorimetric tablets needs to be further improved.
