摘要 目的:研究技工操作因素对义齿树脂基托颜色的影响。方法:将不同粉液比、充填时期、聚合温度、冷却出盒温度和搅拌方式成型的义齿树脂基托试件48个,用色差仪测定各实验组与对照组之间CIE L*a*b*色差值ΔE,用Chroma色差分析软件分析各实验组与对照组之间颜色差异;同时,挑选三个观察者用肉眼观察各组颜色差异。结果:义齿树脂基托颜色的差异,主要存在于单体含量过低、充填过早、热处理升温过快、出盒温度过高、搅拌不充分组。结论:本研究为保持义齿树脂基托颜色稳定及正确的操作方法提供实验依据。 Objective To study the color of denture resin influenced by technical factors. Methods Forty-eight bar specimens of denture resin base were fabricated by different monomer content conditions, resin stage conditions, polymerization temperature conditions, mix methods and cooling temperature conditions. Changes from color data in CIE L*a*b* color space were measured with a colorimeter. Data were analysed with Chroma color analyzing software. At the same time, the color differences between control group and each different experimental groups were observed by three people with naked eye. Results The influencing factors of the color difference of denture resin base were lower monomer content,earlier packing time,quick polymerization process,higher cooling temperature and unfit mixing method. Conclusion This study offers foundations for keeping color stability and standard method of making denture resin base for prosthodontical technicians.
