The aim of this study was to verify the reproducibility and accuracy preoperative planning in maxilla repositioning surgery performed with use computer-aided design/manufacturing technologies mixed reality surgical navigation, using new registration markers HoloLens headset. Eighteen patients a mean age 26.0 years were included. Postoperative evaluations conducted by comparing virtual operation...

Purpose This in vitro study aimed at ascertaining the retention forces for telescopic crowns fabricated with Selective Laser Manufacturing (SLM) and Sintering (SLS) additive technologies, Computer Aided Design – (CAD–CAM) subtractive technology, by using suitable materials each.

In this paper we present a framework and an associated support system for the design of Product Oriented Manufacturing Systems (POMS). This includes the characterization and description of the structure and components of the support system, including database, user interface and knowledge base. The framework components are integrated into an organized system called CADS_POMS (Computer Aided Des...

Computer-aided design of modern robotic manufacturing cells involves solution of a number of complicated optimization problems that are related to equipment selection, scheduling, routing and path planning. The paper deals with three of them: optimal selection of robotic tools, optimal clustering of welding dots among robots, and optimal layout design. A number of efficient genetic algorithms a...

Background: This study aimed to assess the fracture resistance of zirconia restorations fabricated with rapid layer (RL group) technique and zirconia computer-aided design/computer-aided manufacturing (zir/CAD/CAM) system (ZC group). Methods:This study evaluated 30 all-ceramic crowns in two groups of 15. After fabricating the metal dies and scanning them ...

Conceptual process planning is a key activity for designers to evaluate manufacturability and manufacturing cost and time in the early product development stage. Since major manufacturing cost is determined in early design, it is critical to be able to assess manufacturability and cost as early as possible in the design process. The integration between process planning and design is critical to...
