摘要
目的 :研究松风HALO技工比色板修饰瓷粉颜色分布及各组修饰色的应用。方法 :采用数码摄影和计算机技术对松风HALO技工修饰瓷比色板进行测量 ,根据比色板不透明修饰色、浓缩色、配合色、牙龈色的L 、a 、b 、Ca b 值分别绘制L -C及a -b散点图。结果 :牙龈色a 值较高 ,能够表现牙龈粉红色彩效果 ;不透明层修饰色具有高亮度和彩度分布区域广 ,不透明等特点 ,其修饰功能非常强 ;浓缩色具有高亮度、低彩度的特性 ,配合色其亮度、彩度a 、b 值均接近 ,两者与牙本质瓷粉和切端瓷粉混合时 ,能够加强其颜色 ,但是降低亮度和提高彩度负面影响较小。结论 :松风HALO技工比色板修饰色的亮度、彩度分布区域以及组成色调a 、b 值分布范围非常广阔 ,足以模拟正常人牙齿颜色 。
Objective:The purpose of this study is to reveal the lo gi cal of color range in Shofu HALO stain shade guide and method applying to each g roup of sta in porcelain powder.Methods:Applying digital-p hoto and computer to measure Shofu HALO stain shade guide ,according L *?a *?b *? Ca *b * of it to draw L- C and a-b scattering-dot range picture of Opaque modifier , Concentrate , Effect ,Gingival.Results: Gingival has much more value in a * then any other and can show pink color effects of gingival; Opaque odifier has very strong function in stain because of characteristics of high Light value, large distribution area in Chrome value, n on-translucence. Concentrate has characteristics of high Light and Effect come c lose a *and b * to each other, both can strengthen color when mixing with porcelain powder of body and incisor.Conclusions:Shofu HAL O stain shade guide has large distribution area in value of Light, Chrome, a *, b *, can imitate teeth color of human being completely. It is very importa nt for technicians to be done their best understanding what is stain color reall y means. [
