目的。最近，患者的要求不仅在美观方面而且在预先可视化治疗计划方面都发生了变化。本研究的目的是评估一种使用全数字微笑流程的新型 3D-CAD-CAM 数字规划技术。材料和方法。研究参与者包括 28 名成年牙科患者，年龄在 19 岁至 53 岁之间，没有口腔、牙周或全身疾病。对于每位患者，拍摄 3 张口内和口外照片以及口内数字印模。将 2D 数字微笑系统软件和扫描仪立体光刻 (STL) 文件改进的数字图像与 3D 数字微笑系统相匹配，以获得牙齿和微笑设计的虚拟预览。然后，使用 CAM 系统铣削模型。以模型作为位置指南，在牙釉质表面进行微创制备。结果。患者发现数字微笑设计预可视化 (64.3%) 和铣削模型测试 (85.7%) 非常有效。结论。新的全3D数字规划技术是一种可预测的微创技术，可以轻松诊断，改善与患者的沟通，有助于减少工作时间和通常与经典修复手动步骤相关的错误。
Purpose. Recently, the request of patients is changed in terms of not only esthetic but also previsualization therapy planning. The aim of this study is to evaluate a new 3D-CAD-CAM digital planning technique that uses a total digital smile process. Materials and Methods. Study participants included 28 adult dental patients, aged 19 to 53 years, with no oral, periodontal, or systemic diseases. For each patient, 3 intra- and extraoral pictures and intraoral digital impressions were taken. The digital images improved from the 2D Digital Smile System software and the scanner stereolithographic (STL) file was matched into the 3D-Digital Smile System to obtain a virtual previsualization of teeth and smile design. Then, the mockups were milled using a CAM system. Minimally invasive preparation was carried out on the enamel surface with the mockups as position guides. Results. The patients found both the digital smile design previsualization (64.3%) and the milling mockup test (85.7%) very effective. Conclusions. The new total 3D digital planning technique is a predictably and minimally invasive technique, allows easy diagnosis, and improves the communication with the patient and helps to reduce the working time and the errors usually associated with the classical prosthodontic manual step.
