Customization of post-and-cores using computer-aided design and computer-aided manufacturing (CAD-CAM) requires the scanning of a pattern and the subsequent digital design. This technique describes a method of fabricating a CAD-CAM-customized post-and-core designed from a scanned polyvinyl siloxane impression and milled from a nanoparticle/nanocluster-filled resin block. The polyvinyl siloxane impression allowed a faster and more efficient customization of the CAD-CAM post-and-core than a conventional acrylic resin pattern. The properties of the nanoparticle/nanocluster filled resin block make the material suitable for chairside CAD-CAM post-and-core fabrication.
使用计算机辅助设计和计算机辅助制造（CAD-CAM）进行核桩定制需要扫描模型并进行后续的数字设计。本技术描述了一种从扫描的聚硅氧烷印模制作并从填充纳米颗粒/纳米团簇的树脂块铣削出 CAD-CAM 定制核桩的方法。聚硅氧烷印模允许比传统的丙烯酸树脂模型更快、更有效地定制 CAD-CAM 核桩。填充纳米颗粒/纳米团簇的树脂块的特性使得该材料适合椅旁 CAD-CAM 核桩制作。
