【摘要】：目的： 檢測(cè)4種不同品牌熱凝義齒樹脂基托材料在紅酒、可樂、咖啡及茶四種溶液中浸泡不同時(shí)間的顏色變化及光澤度變化，測(cè)定4種樹脂基托材料的吸水值和溶解值，評(píng)價(jià)4種樹脂基托材料的顏色穩(wěn)定性，探討樹脂基托材料顏色穩(wěn)定性與吸水性和溶解性及光澤度的關(guān)系，為臨床醫(yī)生正確選用材料、指導(dǎo)義齒的使用和保養(yǎng)提供參考依據(jù)。 方法： 實(shí)驗(yàn)選用臨床常用的4種品牌熱凝義齒樹脂基托材料新世紀(jì)、賀利氏、日進(jìn)和山八，按照材料生產(chǎn)廠家說明書要求分別進(jìn)行加熱固化，待試件固化后取出，用金相砂紙依次打磨試件表面。每種材料分成5組，每組5個(gè)試件，分別浸泡于紅酒、可樂、咖啡及普洱茶中。將試件分別于1、28和84d后從5種浸泡溶液中取出，用光度色度計(jì)測(cè)量每個(gè)試件的顏色，用光澤度儀測(cè)量每個(gè)試件的光澤度。按照ISO1567：1999標(biāo)準(zhǔn)測(cè)量4種品牌熱凝義齒樹脂基托材料的吸水值和溶解值。 結(jié)果： 新世紀(jì)、賀利和山八品牌的樹脂材料隨著浸泡時(shí)間的延長(zhǎng)顏色變化逐漸增加，，賀利氏品牌的樹脂顏色變化趨勢(shì)最大。4種樹脂基托材料在溶液中浸泡1、28和84d后，賀利氏在紅酒中的ΔE值增大最顯著，有統(tǒng)計(jì)學(xué)意義（P0.05）。賀利氏和新世紀(jì)品牌樹脂材料在紅酒中浸泡84d后ΔE值大于3.7，在臨床不可以接受。日進(jìn)品牌樹脂材料在可樂、咖啡和茶中浸泡1、28和84d后，ΔE值差異無統(tǒng)計(jì)學(xué)意義（P0.05）。賀利氏品牌樹脂基托材料在紅酒中浸泡84d后光澤度下降明顯，差異有統(tǒng)計(jì)學(xué)意義（P0.05）。此外，賀利氏樹脂的吸水值高于其他品牌樹脂，差異有統(tǒng)計(jì)學(xué)意義（P0.05）。 結(jié)論： 通過對(duì)不同熱凝樹脂基托材料在4種浸泡溶液中浸泡1、28和84d后的顏色和光澤度變化以及材料的吸水值和溶解值的數(shù)據(jù)分析得出以下結(jié)論： 1、義齒樹脂基托材料的組成成分、浸泡的時(shí)間和浸泡溶液的性質(zhì)均不同程度地影響樹脂材料的顏色穩(wěn)定性，日進(jìn)品牌的樹脂材料顏色穩(wěn)定性最高。 2、義齒樹脂基托材料的顏色變化，與材料的吸水性和溶解性及光澤度有關(guān)。賀利氏品牌樹脂材料在紅酒中浸泡84d后的顏色變化最顯著，與其吸水值較高和光澤度下降值較大有一定的相關(guān)性。
[Abstract]:Objective:. The changes of color and glossiness of four different brands of thermosetting denture resin base materials in red wine, cola, coffee and tea for different time were detected, and the water absorption and dissolution values of four kinds of resin base materials were determined. The color stability of four kinds of resin base materials was evaluated and the relationship between color stability and water absorption solubility and glossiness of resin base materials was discussed in order to provide reference basis for clinicians to select materials correctly and guide the use and maintenance of denture. Methods:. In the experiment, four kinds of commonly used thermocoagulant denture resin base materials, such as New Century, Holly's, Rijin and Shanba, were used for heating curing in accordance with the requirements of the material manufacturer's instructions, and the samples were taken out after curing. The surface of the sample was polished with metallographic sandpaper. Each material was divided into 5 groups, each group of 5 samples were soaked in red wine, cola, coffee and Pu'er tea respectively. The samples were removed from 5 kinds of soaking solutions after 1: 28 and 84 days, respectively. The color of each sample was measured by photometric colorimeter, the gloss of each specimen was measured by gloss meter, and the water absorption and dissolution values of four kinds of thermal denture resin base materials were measured according to ISO1567:1999 standard. Results:. In the new century, the color changes of resin materials of Heli and Shanba brand gradually increased with the prolongation of soaking time. The color change trend of resin of Heli's brand was the greatest. 4 kinds of resin base materials were soaked in solution for 1h 28 d and 84 d later. The 螖 E value of Holly's red wine increased most significantly, with statistical significance (P 0.05). The 螖 E value of Holly's and New Century brand resin materials was greater than 3.7 after they were soaked in red wine for 84 days, which was not acceptable in clinical practice. There was no significant difference in 螖 E value between coffee and tea after being soaked for 1 ~ 28 and 84 days (P < 0.05). After 84 days of immersion in red wine, the gloss of the resin base material of Holly's brand decreased obviously, and the difference was statistically significant (P 0.05), in addition, there was no significant difference in 螖 E value between coffee and tea after soaking in red wine for 84 days. The absorbency of Heli resin was higher than that of other brands, and the difference was statistically significant (P 0.05). Conclusion:. The following conclusions were obtained by analyzing the changes of color and gloss, water absorption value and dissolution value of different thermosetting resin base materials after being immersed in four kinds of immersion solutions for 1d and 84d. 1. The composition of denture resin base material, the time of soaking and the properties of soaking solution all affect the color stability of resin material to some extent, and the color stability of resin material of daily brand is the highest. 2, the color change of denture resin base material is related to its water absorption, solubility and gloss. There is a certain correlation with its higher water absorption value and greater gloss decreasing value.
