    • The invention provides systems for integrated haptic design and fabrication of dental restorations that provide significant advantages over traditional practice and existing computer-based systems. The systems feature technical advances that result in significantly more streamlined, versatile, and efficient design and fabrication of dental restorations. Among these technical advances are the introduction of voxel-based models; the use of a combination of geometric representations such as voxels and NURBS representations; the automatic identification of an initial preparation (prep) line and an initial path of insertion; the ability of a user to intuitively, haptically adjust the initial prep line and/or the initial path of insertion; the automatic identification of occlusions and draft angle conflicts (e.g., undercuts); the haptic simulation and/or marking of occlusions and draft angle conflicts; and coordination between design output and rapid prototyping/milling and/or investment casting.
    • 本发明提供了用于综合触觉设计和牙科修复体的制造的系统,其提供了优于传统实践和现有的基于计算机的系统的显着优点。 该系统具有技术进步,导致牙科修复体的显着更加精简,多功能和高效的设计和制造。 这些技术进步是引入基于体素的模型; 使用诸如体素和NURBS表示之类的几何表示的组合; 自动识别初始准备(准备)行和初始插入路径; 用户直观地,高度地调整初始制备线和/或初始插入路径的能力; 闭塞和拔模角冲突的自动识别(例如,底切); 触觉模拟和/或遮挡和拔模角冲突的标记; 以及设计输出与快速原型/铣削和/或熔模铸造之间的协调。
