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...

This panel will discuss a rapidly expanding application area of databases: Computer aided design and manufacturing (CAD/CAM). CAD is playing an important role in diverse fields such as logic design, printed wiring board design, chemical process control, structural engineering, architecture, aircraft and automobile design, design of mechanisms, cartography, etc. On the one hand, all these applic...

In 2007 we have computing power and infrastructure that are emarkable in terms of both speed and cost. A casual observer ould expect the effects of this technological “free lunch” on omputer Aided Manufacturing CAM to be an equally dramatic dvance. However it is a measure of this field’s difficulty that very ew of the problems, which invariably involve complex threeimensional geometry, can be s...

This paper presents results of a case study undertaken to understand the effect of computer assisted teaching methodology on learning effectiveness in a laboratory environment. The effects of computer assisted instructions on different levels of cognition of individual learners, as described by Bloom’s Taxonomy have been evaluated. For this students in mechanical engineering subject area were e...
