Further it has been reported that water, oxygen, chloride, sulphur corrodes various metal present in the dental alloys
A technique for characterizing casting behavior of dental alloys
These findings suggest that exposure to Cd released from dental alloy
restorations may influence many aspects of mineralized hard tissue of teeth and their immediate surrounding periodontal tissues.
Key words: welding, dental alloys
, laser, non-invasive methods, metallography, scanning electronic microscopy
The selection of the dental alloy
should be based on the salivary pH evaluation of each patient.
Since nickel is the most common metal used in different dental alloys
, orthodontic appliances and maxillofacial surgery, hence the present study was designed to get the exact lytic effect of nickel sulphate on gross, histological as well as biochemical basis.
In a study conducted by Dong H et al9 authors used a 7-day immersion test in which they studied the tendency of dental alloys
to corrode in neutral water weak acid water and electrolyzed strong acid water.
Regarding the questioned biocompatibility of Ni-Cr alloys, in 2006 Setcos et al (17) published a review about the safety of dental alloys
containing nickel, concluding that this element is found in many of the alloys used in dentistry, and that such alloys have a long history of successful use, with no reports of significant unwanted biological effects.
Metallurgical structures of as-cast and heat-treated high-palladium dental alloys
Lab owner Graham Cobb says there is an ISO test for corrosion of dental alloys
, "but nobody has paid to put this alloy through the ISO corrosion test.
Key words: macroscopic visual inspection, electron microscopy, Ni-Cr dental alloys
, laser welding, prostheses
In 2002 the group further diversified with the acquisition of Global Envirotec Solutions to boost its environmental division as well as Charles Booth, a supplier of dental alloys
Although in the last few years there have been some attempts to use numerical modelling techniques for a better understanding or even solving of aspects related to the melting and casting of dental alloys
, by using software packages like Magmasoft, Fluent or JSCast, there has been no systematic approach to the usage of computer-aided modelling and simulation software for the optimisation of the design of small-size casting moulds (Wu, 2002).
The far ranging applications of Fischer's Goldline Assay encompass Assay Offices for the determination of purity, jewellery and the watch trade, coin mints, customs authorities, laboratories responsible for gold and precious metal determinations, separation institutes and recycling companies and manufacturers and processors of dental alloys
