口腔修复材料的颜色稳定性研究

摘要

目的:研究在唾液、茶、红酒等溶液中口腔修复材料的颜色稳定性.方法:制备树脂、烤瓷、聚合瓷试件各12个,进行稳定性检测,并对其进行对比分析.结果:不同时间、溶液、材料对口腔修复材料的颜色稳定性存在明显差异.结论:三组口腔修复材料中,树脂材料和聚合瓷材料均随时间增加而产生色差增加,并显示出初始色差增加明显的特征.%Objective: To study the total dental prosthetic material in the solution of the saliva, tea, red wine and other color stability. Method: Preparation of resin, porcelain, polymer ceramic specimen 12, stability testing, and comparative analysis. Result: The different time, solution, material for color stability of dental prosthetic material was significantly different. Conclusion: The three groups of dental prosthetic material , resin and polymer ceramic material increase in chromatic aberration increase with time, and shows the characteristics of the initial component increased significantly.
