“HSB色彩模型”的数字化在色素牙修复中的应用研究

摘要

目的:运用“HSB色彩模型”的数字化,提高临床色素牙修复的协调性与精确度.方法:选取2001年6月～2010年6月我科32例色素牙修复患者,共48颗瓷修复体.运用数码相机采集与患者色素牙相近明度的Vita 3D-Master26色比色板中的标准色片的数码照.依据孟塞尔(Munse11)颜色系统,通过“HSB色彩模型”H、S、B数字化,确定最小色差的特定色色片组合,指导瓷粉重组与调配,并对修复体色质效果满意度评价.结果:48颗色素牙修复体中,46颗色质良好,与邻牙色质协调,成功率96％.经卡方检验,x2=23.85,P＜0.05,运用“HSB色彩模型”的数字化指导瓷粉重组修复与标准色片比色修复的满意程度有显著差异.结论:运用“HSB色彩模型”的数字化,通过最小色差的组合色片指导瓷粉重组,修复体能完全覆盖所有色素牙的颜色区域,该方法科学、量化、方便、精确.%Objective The aim of this study is to improve coordination and accuracy of clinical pigment teeth in dental restoration by using the digitization of "the HSB color model". Methods 32 cases of pigment in patients with dental restoration were chosen during June 2001 to June 2010 with a total of 48 ceramic restorations.The digital photos of the brightness of the standard color chip in Vita 3D-Master26 color swatch which were similar to patient's pigment teeth were collected by digital camera.The combination of minimum chromatic aberration color film was determined and guide the porcelain powder reorganization and deployment by the digitization of HSB color model according to Munsell (Munsell) color system,then the satisfactory of dental prosthetic restoration's color quality was evaluated. Results 46 dental prosthetic restorations' color quality were in coordination with adjacent teeth's color quality during 48 dental prosthetic restorations.The success rate was 96% There were significant differences of satisfaction between porcelain powder reorganization by using the digitization of HSB color model and standard color film matching in dental prosthetic restoration.x2=23.85,P<0.05,according chi-square test. Conclusion The combination of minimum chromatic aberration color film was determined and guide the porcelain powder reorganization and deployment by the digitization of HSB color model.The dental prosthetic restoration which were guided by HSB completely cover the region of the pigment teeth's color,lt suggested that the method was scientific,quantitative,convenient,and accurate.
