In this study we examined the hypothesis based on relevant literature survey that the in vitro corrosion behavior of a Cobalt-chrome dental casting alloy for metal-ceramic restorations is better than that of a Nickel-chrome dental casting alloy. The corrosion released metal ions were analysed by Inductively Coupled Plasma-Atomic Emission Spectroscopy. Moreover, the specimens were electrochemica...

The presented paper studies the effect of the casting technology on the corrosion resistance of Co-Cr-Mo alloy. The investigations were conducted on a commercial alloy with the brand name ARGELOY N.P SPECIAL (Co-Cr-Mo) produced by Argen as well as the same alloy melted and cast by the lost wax casting method performed by a dental technician. The corrosion behavior of the dental alloys in an art...

Various alternatives are available when designing a data collection system for portfolio investment (PI) statistics, in the context of balance of payments (BOP) and international investment position (IIP). Such systems differ according to the reporting agents they target, periodicity and level of aggregation, while the corresponding results vary in terms of implementation and running costs, ava...

This research develops an innovative free-form surface scanning system using laser triangulation for 3D dental data required for crown reconstruction. This novel design employs double laser diodes to produce two 45° structured-light lines projecting onto the plaster tooth models and three CCD cameras to capture deformed fringes to achieve fast and accurate 3D surface measurement of plaster toot...

It has been documented in vitro and in vivo that metal dental appliances release metal ions due to corrosion. Dentists must choose among many dental casting alloys available, often without knowledge of their biological properties and effect on oral mucosa. The aim of this study was to measure metal content of nickel (Ni) and chromium (Cr) in whole saliva of 85 patients with and without metal de...
