Abstract

This article describes a digital workflow for ceramic veneer preparation using computer-aided design and computer-aided manufacturing technology. A digital waxing was planned on the exocad software program to reestablish esthetic and functional parameters. Then, the digital guides for veneer preparation were designed by using the Meshmixer design software program to control the tooth structure removed during preparation to the minimal thickness necessary for the definitive restorations. The digital guides were printed in an additively manufactured clear resin and used in the preparation appointment, allowing a more conservative and controlled preparation.

摘要

本文介绍了一种使用计算机辅助设计和计算机辅助制造技术进行陶瓷贴面预备的数字化工作流程。在 exocad 软件程序上进行数字化蜡型设计，以重建美观和功能参数。然后，使用 Meshmixer 设计软件程序设计贴面预备的数字引导，以控制预备过程中去除的牙体结构达到最终修复体所需的最小厚度。数字引导采用增材制造的透明树脂进行打印，并在预备预约时使用，允许进行更保守和可控的预备。
