This study aimed to evaluate the production of customized composite veneers starting from a two-dimensional (2D) digital preview using the Digital Smile System (DSS). MATERIAL AND METHODS: A photographic examination of 30 patients was performed by taking two digital pictures of the face and a digital preview through the DSS. Moreover, optical scans of the dental arches were obtained and the data were entered into a three-dimensional (3D) software to prepare a virtual preview. The standard tessellation language files were sent for production using CAD-CAM technology. The Friedman test, Bonferroni, and Dunn post hoc tests were used, comparing the linear measurements of the 2D and 3D plans and the final veneers (α = .05).
Significant differences emerged between the pictures and digital scans on the mesial-distal widths of the lateral incisors and canine. Linear measurements in the 2D plan were significantly different from those of the 3D plan, except for the height measures of incisors. No significant changes were found on comparing the parameters of the 2D and 3D plans with those of the final pieces.
The customized veneers were clinically adequate and similar to 2D and 3D plans, although significant differences emerged between the picture and digital scans as well as between the 2D and 3D plans.
本研究旨在评估通过数字微笑系统（DSS）从二维（2D）数字预览制作定制复合贴面的效果。
对 30 名患者进行了摄影检查，通过 DSS 拍摄面部的两张数字照片和一张数字预览照片。此外，还获取了牙弓的光学扫描，并将数据输入到三维（3D）软件中以准备虚拟预览。将标准镶嵌语言文件发送到 CAD-CAM 技术进行生产。使用 Friedman 检验、Bonferroni 和 Dunn 事后检验进行比较，比较 2D 和 3D 计划以及最终贴面的线性测量值（α=0.05）。
照片和数字扫描在侧切牙和尖牙的近远中宽度上存在显著差异。2D 计划中的线性测量值与 3D 计划中的测量值存在显著差异，除了切牙的高度测量值。比较 2D 和 3D 计划与最终部件的参数时，未发现显著变化。
定制贴面在临床上是足够的，并且与 2D 和 3D 计划相似，尽管照片和数字扫描以及 2D 和 3D 计划之间存在显著差异。
