Corrosion resistance of stainless steel, nickel-titanium, titanium molybdenum alloy, and ion-implanted titanium molybdenum alloy archwires in acidic fluoride-containing artificial saliva: An in vitro study
OBJECTIVE (1) To evaluate the corrosion resistance of four different orthodontic archwires and to determine the effect of 0.5% NaF (simulating high fluoride-containing toothpaste of about 2250 ppm) on corrosion resistance of these archwires. (2) To assess whether surface roughness (Ra) is the primary factor influencing the corrosion resistance of these archwires. MATERIALS AND METHODS Four di...
متن کاملTitanium-Aluminum Oxide Coating on Aluminized Steel
In this study, a plasma electrolytic oxidation (PEO) process was used to form titanium-aluminum oxide coating on aluminized steel. The present work was mainly to study the effects of treatment time of PEO process on properties of the titanium coating. A potentiodynamic polarization corrosion test was employed to investigate the corrosion resistance of the coating. The friction coefficient and w...
متن کاملTitanium Nitride and Nitrogen Ion Implanted Coated Dental Materials
Titanium nitride and/or nitrogen ion implanted coated dental materials have been investigated since the mid-1980s and considered in various applications in dentistry such as implants, abutments, orthodontic wires, endodontic files, periodontal/oral hygiene instruments, and casting alloys for fixed restorations. Multiple methodologies have been employed to create the coatings, but detailed struc...
متن کاملBone enhancing effect of titanium-binding proteins isolated from bovine bone and implanted into rat calvaria with titanium scaffold.
Based on our previous finding that a chromatography with titanium beads selectively binds phosphoproteins, including caseins, phosvitin and dentin phosphoproteins, we investigated whether bone phosphoproteins also bind to titanium. Bovine bone matrix proteins were extracted with 2 M urea/PBS after demineralization. The 2 M urea extract was directly applied to the titanium chromatography column ...
متن کاملNanosurface modification of titanium and titanium coated stainless steel coronary stents for preferential cell functions
Surface modification of metallic implants is proposed as a viable means to alleviate the problems related to in-stent restenosis. Amongst the various surface modification strategies, surface nanotexturing is highlighted as a promising approach to improve the cellular behavior and tissue integration of biomedical implants. This thesis work focuses on developing a polymer-less and drug-free nanos...
