Neoendo flex files are one of the latest rotary endodontic files used in root canal treatment (endodontic therapy). These new endodontic rotary files were manufactured keeping in mind the limitations of conventional shape memory rotary files in endodontics. Neoendo Flex Files undergo a specialized heat treatment process to give them unique flexibility characteristics. Shape memory nickel titanium rotary endodontic files have the limitation of reduced cutting efficiency due to heat treatment in addition to opening of the flutes when stress levels are encountered in the canal. This results in prolonged treatment time and apical extrusion of debris. Neoendo Flex Files however, utilize proprietary heat treatment methods which dos not result in the flutes opening as a result of stress. Advanced surface treatment methods are employed which results in the characteristic golden colour of the file. This surface treatment results in a far superior cutting efficiency of the files. Neoendo Flex Files have a simple usage protocol and reduce chair time for each procedure owing to their superior characteristics
Neoendo Flex Files have excellent cyclic fatigue resistance. The triangular cross section with sharp cutting edges increases cutting efficiency. Avoiding accidental apical transportation becomes easier with the safety tip (non-cutting). The extreme flexibility of this canal favours negotiation of any canal.
The Root Canal System is highly complex and a practitioner may encounter varied types of anatomies. Shape memory file, because of their tendency to straighten up, results in unnecessary loss of dentin and many a times instrument separation. Heat treatment, though renders the file flexible, reduces the cutting efficiency of the blades, not to forget that flutes open even with small stress levels encountered in the canal. This results in not only in increased preparation time, but also apical extrusion of debris during the procedure. Combined with these, the increasing cost of instruments puts pressure on a practitioner's ability to provide quality treatment.
Neoendo Flex Files utilize a proprietary heat treatment which gives it a very unique flexibility, flutes do not open up when stress levels are reached, yet the file does not present shape memory. The golden color of the file is a result of a very sophisticated and technologically advanced surface treatment to achieve a far superior cutting efficiency. A very tough file, Neoendo Flex File has a simple usage protocol, takes less time per case, and presents outstanding performance.
