目的探讨立体数码比色技术在烤瓷修复比色中的应用效果。方法选择前牙烤瓷修复的患者166例(患牙196颗),采用立体数码法(立体比色、拍摄比色数码照片并用Adobe photoshop处理,获取色彩信息)与常规目测法各制作一副修复体;记录患者的色彩满意度。结果立体数码比色满意度为94.6%,对照组满意度62.2%,差异有统计学意义(P<0.05)。结论立体数码比色技术克服了常规比色的不足,可获得自然逼真的色彩再现。
Objective To explore the application effect of three-dimensional digital colorimetric technique in the colorimetric restoration of porcelain. Methods One hundred and sixty-six patients (196 teeth) with anterior teeth porcelain were repaired by stereoscopic digital method (three-dimensional colorimetry, colorimetric digital photography with Adobe Photoshop and color information acquisition) Body; record patient’s color satisfaction. Results The three-dimensional digital colorimetry satisfaction was 94.6%, while that of the control group was 62.2%, the difference was statistically significant (P <0.05). Conclusion Three-dimensional digital colorimetric technology to overcome the lack of conventional colorimetric, natural color reproduction can be obtained.
