System developed by endodontists George Bruder and Ove Peters for Dentsply Sirona. TruNatomy combines Swiss precision with advanced engineering for absolute respect of tooth anatomy. The TruNatomy family consists of a series of files designed to accompany the endodontist throughout the entire process: TruNatomy Orifice Modifier is perfect for preparing access while preserving coronal anatomy thanks to its flexibility, diameter, and NiTi alloy. It is also recommended in cases where the canal is not oriented vertically, as it allows access to the tooth from different angles. TruNatomy Glider facilitates the creation of an effective glide path without the need to apply excessive pressure. TruNatomy files feature a thinner wire design (0.8 mm instead of 1.2 mm) and an off-centered cross-section that provides greater flexibility, allowing the file to curve as needed. They are available in three sizes: small, prime, and medium. These files offer increased safety and a lower risk of breakage due to their flexibility and resistance to cyclic fatigue. Additionally, they save time for the endodontist as they require less shaping time, which can be spent on irrigation. The main advantages of the TruNatomy system include: a smooth feel during canal preparation, improved performance and efficiency, more space for debris removal and elimination of dentin sludge, respect for the natural anatomy of the tooth, and preservation of dental structure.
