Study of the Tribocorrosion occurring at the implant and implant alloy Interface: Dental implant materials

摘要: Abstract This paper quantitatively determines the effects of wear and corrosion phenomenon in dental implant materials when subjected to a simulated oral environment. A is mechanical system that undergoes tribo-corrosion at interface between abutment alloy where material degradation commonly seen. The coefficient, volume loss, depth rate 3 under consideration: Grade 5 Titanium (Ti6Al4V), Yttria Stabilized Zirconia Toughened Alumina are determined. Comprehensive evaluation such tribo-corrosive systems environments will provide clear understanding loss occurs due interactions for combinations various implant-implant materials. consideration were dry sliding accordance with ASTM G99 standard 12,000 cycles. coefficient friction recorded simultaneously pin | disc combinations. To replicate realistic conditions, small surface area was subsequently potentiodynamic polarization technique F2129 reveal concurrent changes kinetics presence Artificial Saliva, being used in-vitro facilitate electrochemical behavior bodily pH levels. The results indicate better suited resist both implants.
