Production systems design is critical to achieving manufacturing performance and objectives. Although generic approaches to this design are available they may not be able to objectively address specific manufacturing configurations. Here it is argued that product oriented manufacturing (POM) organization offers advantages in relation to the function oriented one. Based on this, a methodology sp...

objectives : marginal adaptation is important for long-term success of full-coverage restorations. the aim of this study was to determine the effect of porcelain firing cycle and different thicknesses of ips e.max core on marginal accuracy of all-ceramic restorations. materials and methods : a standard stainless steel die with 0.8 mm classic chamfer finish line and 10° taper was used in this in...

Utilization of computer-aided design/computer-aided manufacturing (CAD/CAM) increases in dental prosthetics. From single restorations and bridges, computer-aided engineering supports fabrication of partial and now complete removable dentures. Improved materials, like crosslinked poly (methyl methacrylate) (PMMA) and CAD/CAM technology permit realization of a superior quality denture in shorter ...

Computer-aided drafting and design (CADD) is a computer-based program that improves the efficiency of product design and components both inside and outside of engineering. In recent years the use of CADD in dentistry, more commonly known as computer-aided dentistry, has become commonplace, allowing doctors and patients to individually design treatment with the result visible through computer-ge...
