DESCRIPTION (provided by applicant): The objective of this project is the development of a portable, moderately priced Computer Aided Design/Computer Aided Manufacturing (CAD/CAM) system for Dental restorations. Preliminary tests have demonstrated that a combination of a contact scanner with a stock milling unit can produce ceramic Dental crowns at a total cost of approximately $25,000 or less. Available systems cost from $49,000 to $250,000, limiting their use and penetration into the marketplace. We will investigate the technical capabilities, scanning rates, restoration design, replication rate and output of a CAD/CAM system constructed from modifying available CAD software, scanner, and milling hardware. Furthermore we will develop capabilities to mill multi-layered/multi-colored blocks to produce restorations with graded color that are more esthetic than current monochromatic milled restorations. This portable system may be used to deliver care to rural, home bound, or other under served populations. Phase I is Aimed at determining the feasibility of the concept with respect to ease of use, scanning accuracy, fabrication time, and comparative cost per restoration. Phase Il involves refinement of the software, scanning and milling process and industrial design of the system. This system will enable the production of high quality restorations with reliable accuracy and lower labor costs.

描述（由申请人提供）：本项目的目标是开发一种便携式，价格适中的计算机辅助设计/计算机辅助制造（CAD/CAM）系统，用于牙科修复。初步测试表明，接触式扫描仪与坯料铣削单元的组合可以生产陶瓷牙冠，总成本约为25，000美元或更低。现有系统的成本从49，000美元到250，000美元，限制了它们的使用和市场渗透。我们将调查的技术能力，扫描速度，修复设计，复制率和输出的CAD/CAM系统，通过修改现有的CAD软件，扫描仪和铣削硬件。此外，我们还将开发研磨多层/多色块的能力，以生产比当前单色研磨的颜料更美观的具有分级颜色的颜料。该便携式系统可用于向农村、家庭或其他服务不足的人群提供护理。第一阶段旨在确定概念的可行性，包括易用性，扫描精度，制造时间和每次修复的相对成本。第二阶段涉及软件的完善、扫描和铣削过程以及系统的工业设计。该系统将能够以可靠的精度和较低的劳动力成本生产高质量的产品。
