DESCRIPTION: The overall goal of this development is a low cost automated fabrication system for indirect, all-ceramic and polymer composite restorations as alternatives to amalgam. Ceramic and polymer composite restorations are available and have shown good results clinically, but are not widely used because of their relatively high cost and/or laboratory processing requirements compared to Dental amalgam. It is anticipated the proposed system will offer faster, lower cost process compared to Dental the conventional and newer CAD-CAM based fabrication techniques (e.g., CEREC II for chairside and Procera for laboratory processing). The fabrication system will be based on rapid prototyping techniques (i.e., additive, layer-by-layer freeform fabrication) and will create all-ceramic and polymer composite Dental restorations directly from three-dimensional (3D) imaging data. The complete system will consist of a 3D intraoral camera for collecting the surface profile of the restoration site, CAD software for creating occlusal and proximal surfaces, an automated fabrication machine that builds the restoration directly from CAD file generated from the scan data, and post processing equipment to fully cure or sinter the restoration making it ready for insertion. Phase I goals are to demonstrate the new process can produce durable Dental restorations with good material properties and accuracy of fit. PROPOSED COMMERCIAL APPLICATION: NOT AVAILABLE

描述：此开发的总体目标是低成本自动化 间接，全陶瓷和聚合物复合修复体的制造系统 作为合并的替代品。陶瓷和聚合物复合修复体是 可用并在临床上显示出良好的结果，但未广泛使用 由于其成本相对较高和/或实验室处理要求 与牙科汞合金相比。预计拟议的系统将提供 与牙齿相比，更快，更低的成本过程 基于CAD-CAM的制造技术（例如，CEREC II用于椅子和Procera 用于实验室处理）。制造系统将基于快速 原型技术（即添加剂，逐层自由式制造） 并将直接创建全科和聚合物复合牙科修复体 从三维（3D）成像数据。完整的系统将包括 3D的口内相机，用于收集修复位点的表面轮廓， 用于创建咬合和近端表面的CAD软件，自动化 直接从CAD文件构建修复的制造机 从扫描数据和后加工设备产生以完全治愈或 烧结恢复，使其准备插入。第一阶段的目标是 证明新过程可以产生耐用的牙科修复体 材料特性和拟合精度。 拟议的商业应用程序：不可用
