Effect of Casting Temperature and Atmosphere on Castability of Ni-Cr Alloys: A Comparative Study with Direct Flame Casting Method
The purpose of this study was to compare the effect of casting temperature and atmosphere on the castability of three Ni-Cr alloys against direct flame casting method. Vera Bond (VB), Vera Bond 2 (VB2) and Wiron 99 (W99) were cast at three temperatures: VB and VB2 (1310 °C, 1340 °C and 1370 °C); W99 (1400 °C, 1430 °C and 1460 °C) in atmosphere, vacuum and direct flame. Each alloy was cast in se...
متن کاملCasting of Titanium Alloys for Dental Applications
In dentistry, gold-based noble metal alloys have traditionally been cast into various types of dental prostheses, such as partial dentures, crowns, and bridges. More recently, less expensive dental alloys with base-metal elements, such as Co-Cr and Ni-Cr, have been used. Titanium is considered to be an attractive alternative to these traditional dental alloys because of its remarkable lack of t...
متن کاملImmunostimulatory capacity of dental casting alloys on endotoxin responsiveness.
STATEMENT OF PROBLEM Oral metal exposure has been associated with systemic and local adverse reactions, probably due to elemental release from the alloys. Although supraphysiological concentrations of salts from dentally applied metals can activate innate cells through TLR4 (Ni, Co, Pd) and TLR3 (Au), whether direct exposure to solid alloys can also trigger innate immune reactivity is still unk...
متن کامل[Initial corrosion of dental casting alloys in the oral environment].
In order to study the initial corrosive changes of dental casting alloys in the mouth, the condition and composition of the proximal surface of the class II inlay were analyzed by the scanning electron microscope (SEM) and the electron probe microanalyser (EPMA). These analyses on the same small areas of the proximal surface were carried out every week for four weeks. The results were compared ...
متن کاملReaction of fibroblasts to various dental casting alloys.
The cytotoxicity of a series of dental casting alloys in the as-cast and polished condition was determined with cell culture techniques involving phase contrast microscopy to examine cell morphology and the succinic dehydrogenase histochemical reaction to measure any ring of inhibition of Balb/c 3T3 cellular respiration around alloys. Crown and bridge casting alloys and a nickel- and a cobalt-b...
