在获取用于数字微笑设计 (DSD) 和牙种植体规划的 3 维 (3D) 面部图像时，嘴唇朱红边界和牙齿之间区域的变形可能经常导致不准确。目前的临床技术旨在减少面部扫描过程中的这种变形，从而促进 3D DSD。这对于为种植体重建精确计划骨质减少也是必不可少的。定制的硅胶基质充当蓝屏，为需要新的上颌螺钉固位种植体支持的固定全口义齿的患者提供可靠的面部图像 3D 可视化支持。添加硅胶基质后，面部组织会出现难以察觉的体积变化。通过应用带有硅胶基质的蓝屏技术，克服了面部扫描中唇红边缘的常见变形。准确再现唇部轮廓的朱红色边界可以为 3D DSD 提供改进的通信和可视化。硅胶基质是一种实用的方法，它充当蓝屏，以令人满意的精度显示从嘴唇到牙齿的过渡。在重建牙科中实施蓝屏技术可以通过减少扫描具有难以捕获表面的物体时的错误来提高可预测性。硅胶基质是一种实用的方法，它充当蓝屏，以令人满意的精度显示从嘴唇到牙齿的过渡。在重建牙科中实施蓝屏技术可以通过减少扫描具有难以捕获表面的物体时的错误来提高可预测性。硅胶基质是一种实用的方法，它充当蓝屏，以令人满意的精度显示从嘴唇到牙齿的过渡。在重建牙科中实施蓝屏技术可以通过减少扫描具有难以捕获表面的物体时的错误来提高可预测性。

Enhanced Lip-Contour During Facial Scan for 3D DSD and Implant Planning: A Blue Screen Approach.

When obtaining 3-dimensional (3D) facial images for digital smile design (DSD) and dental implant planning, inaccuracies may frequently be introduced by distortion in the region between the lips' vermilion border and the teeth. The present clinical technique aimed to reduce such deformation during face scanning, thereby facilitating 3D DSD. This is also essential to plan bone reduction with precision for implant reconstructions. A custom-made silicone matrix acting as a blue screen provided reliable support for 3D visualization of facial images in a patient requiring a new maxillary screw-retained implant-supported fixed complete denture. Imperceptible volumetric changes were registered in the facial tissues when the silicone matrix was added. The usual deformation of the lip vermilion border originating in face scans was overcome by applying blue-screen technology with a silicone matrix. Reproducing the vermilion border of the lip contour accurately may offer improved communication and visualization for 3D DSD. The silicone matrix was a practical approach that acted as a blue screen to display the transition from lips to teeth with satisfactory precision. Implementing blue-screen technology in reconstructive dentistry might increase predictability by reducing errors when scanning objects with challenging-to-capture surfaces.
