Abstract
一种专门用于四环素牙瓷修复的比色板。通过建立四环素牙患者色度值L*a*b*数据库,对L*a*b*进行系统聚类分析,确定比色板色标的色度值。结合色标的代表性和临床使用方便,设计12块色标。比色板色标按照L*值从高到低排列,色标排列有规律;由于色标的色度值是通过对四环素牙颜色的分析而专门设计,因此与对应四环素牙的色差更小。该比色板在四环素牙烤瓷或全瓷修复中,能够帮助医生和技师更加准确地配色,为四环素牙患者提供颜色更加匹配的瓷修复体。
Description
所属技术领域
本发明涉及一种四环素牙烤瓷或全瓷修复中用到的比色装置,尤其是凭肉眼主观比色参照的比色板。
背景技术
目前,公知的四环素牙烤瓷或全瓷修复中进行肉眼主观比色所参照的是正常牙齿烤瓷或全瓷修复参照的比色板。在该比色板中选择与患者牙齿颜色最为接近的色标,由技师按照该色标的颜色加工瓷修复体。但是,四环素牙与正常牙齿的颜色特征存在差异,很多四环素牙在正常牙齿瓷修复参照的比色板中找不到合适的对应色标,给临床工作带来了困难。
发明内容
为了克服现有的通用型比色板在四环素牙烤瓷或全瓷修复中颜色匹配的不足,本发明提供一种四环素牙瓷修复专用比色板,该比色板根据四环素牙的颜色特征进行了专门设计,能够帮助医生和技师更加准确地配色,解决临床工作的实际困难。
本发明解决其技术问题所采用的技术方案是:首先对患者的四环素牙测色,建立四环素牙患者色度值数据库。所得色度值L*a*b*用SPSS统计分析软件进行系统聚类分析,确定比色板色标的色度值。结合色标的代表性和临床使用方便,该比色板设计12块色标。在决定颜色的三项色度值参数L*、a*、b*中,L*的差异对颜色差异的感知影响最大,因此所设计的比色板色标按照L*值从高到低排列,色标排列有规律;由于色标的色度值是通过对四环素牙颜色的分析而专门设计,因此与对应四环素牙的色差更小。
本发明的有益效果是,在四环素牙的烤瓷或全瓷修复中,可以更加准确地比色,有利于医生对患者牙齿颜色的描述和表达,有利于技师对患者颜色的了解和再现,因此可以为四环素牙患者提供颜色更加匹配的瓷修复体,达到更好的临床修复疗效。
附图说明
下面结合附图和实施例对本发明进一步说明。
附图是本发明的结构示意图。图中1.比色板色标,2.比色板基座。
