This article describes a 3D virtual diagnostic analysis for treatment planning an esthetically driven functional rehabilitation by using computer-aided design and computer-aided manufacturing (CAD-CAM) technology. In this protocol, a digitally planned diagnostic waxing (exocad DentalCAD) was used to visualize the proposed tooth position and the presence of areas without sufficient material thickness for the prospective additive restorations. This approach uses an additively manufactured clear resin guide to selectively reduce surfaces of a tooth erupted beyond the proposed occlusal plane. By using a 3D-printed occlusal reduction guide, the digital diagnostic waxing is accurately represented, tooth reduction controlled, and adequate occlusal clearance for the required restorative material thickness provided with a minimally invasive approach.
本文描述了一种使用计算机辅助设计和计算机辅助制造（CAD-CAM）技术进行美学驱动的功能性修复治疗计划的 3D 虚拟诊断分析。在本方案中，使用数字化设计的诊断蜡型（exocad DentalCAD）来可视化建议的牙齿位置以及是否存在潜在的修复材料不足的区域。该方法使用增材制造的透明树脂导板选择性地减少超出建议咬合平面的牙齿表面。通过使用 3D 打印的咬合降低导板，可以准确地呈现数字化诊断蜡型，控制牙齿降低，并为所需的修复材料厚度提供最小侵入性的足够的咬合间隙。
