Product Upgrade – Rational Preparation Approach: One Curve becomes MicroMega One Curve mini

Maximize the chances of a successful endodontic treatment, while minimizing the mechanical impact: One Curve becomes MicroMega One Curve mini.

Manufactured from heat-treated Nickel-Titanium alloy with a patented variable cutting section design, MicroMega One Curve mini is a single-use, rotary file that enables shaping of the full length of the canal with a single instrument, directly to the apex.

With rational preparation, COLTENE wants to reach the goal of respecting the sound tooth structure as much as possible and still ensure a successful and effective endodontic treatment at the same time.

Therefore, over the last months, COLTENE rolled out its expertise and know-how to gather different key features of its files such as smaller NiTi Wire of 1mm, small sizes/taper, C.Wire heat treatment and cutting efficiency.

These features will allow a dentist to appreciate the benefits of a rational approach:


  • To preserve peri cervical dentin


  • To remove minimum of tooth structure¹


  • To respect the root canal anatomy²


  • To create optimal space for a deep disinfection and a proper obturation
