Testing of bent wire denture clasp metal's hardness and condition after titanium and zirconium nitride plasma spraying on its surface

Cover Page

Abstract


The durability comparative analysis of samples after different technologies of bent wire denture clasp treatment proved statistically significant declination of its density characteristics after titanium and zirconium nitride plasma spraying on its surface.
This declination is accompanied by experimentally found change in microhardness density distribution after plasma spraying (especially after zirconium nitride plasma spraying). The density declination in comparison with its initial state is one of the main reasons of bent premature denture clasp destruction in human mouth cavity exploitation.
