New thermomechanically treated NiTi alloys – a review [PDF]
International Endodontic Journal, 2018 AbstractIn the past 10 years, several proprietary processing procedures for nickel titanium (NiTi) alloy were developed to improve the mechanical properties of NiTi endodontic instruments. Beside specific thermal and mechanical treatments, manufacturers introduced several machining procedures (e.g.
