摘要
目的 研究 VITA VMK95技工比色板各层瓷粉颜色分布的规律性。方法 采用数码摄影、计算机技术和国际印刷协会推荐的 PANTONE HEXACHROM标准色标对 VITA VMK95技工比色板的不透明瓷、牙本质瓷、颈部瓷、切端透明瓷进行测量。结果 随着 A、B、C、D各组比色板色阶的增大 ,不透明瓷、牙本质瓷的 L*值呈递减趋势 ,a*、b*值呈递增趋势 ,但是颈部瓷、透明瓷的 a*、b*值的递增趋势变化不明显。牙本质瓷所占有的颜色分布区域较颈部瓷、不透明瓷、透明瓷大。结论 VITAVMK95技工比色板各层瓷粉颜色分布具有一定的有序性 ;牙本质瓷颜色分布区域较大 ,是决定牙齿颜色的主要因素。
Objective The purpose of this study is to reveal the ordering of colorrange in VITA VMK95 technical shade guide on each lay porcelain powder. body and incisor and order in shade guide of each group. Method Applying the method of Digital-photo and computer and stander color sample of the International Print Association of suggesting Pantone Hexachrom measure opaque,body,cervical,incisor translucent. Results L * in pat of opaque and body become decrease and a *,b * become increase generally with the increase of each group of color guide stage,then a *、b * of incisor translucent and cervical increase tendency unapparently. The color range of body porcelain is larger the opaque, cervical and incisor translucent. Conclusion There are logical order of color range in VITA VMK95 technical shade guide in porcelain of opaque, cervical, body and incisor translucent. With color range of it, body porcelain is the main factor deciding the color in teeth.
