The New View towards EDM Files
Journal Title: Open Access Journal of Dental Sciences - Year 2016, Vol 1, Issue 1
Abstract
With continuous evolution of NiTi file system it has become a challenge to choose between the right system for individual clinical scenario. The various thermomechanic procedures and the improvement of composition of the alloy that is used in manufacturing NiTi files are aimed to improve the flexibility of NiTi files. Improved flexibility of NiTi files would minimize the intracanal irregularities such as canal transportation and would ensure an increase in the success of root canal therapy. Technically speaking there is a phase shift from milling of alloy to electro discharge machining of alloy. Electro-discharge machining (EDM) is a non-contact thermal erosion process that partially melts and evaporates the wire by high-frequency spark discharges. There is significant difference in surface architecture of nickel titanium after thermal treatment. Electro discharge machining gives better fatigue resistance property hence more predictable outcome.
