Use for enlarging root canal and negotiating calcified and narrowed root canal.

During the process of canal negotiation, Shape D are prone to maintaining the original canal morphology, preventing lateral perforation or step formation, thereby reducing the occurrence of complications.


Stainless steel for high resistance to fracture.

Shape D feature a unique ISO 0.02 taper and are made of stainless steel, which grants them sufficient strength and toughness while meeting clinical requirements.




Shaped D cross section for better piercing ability.

Shape D possess a "D"-shaped cross-section, a design that increases the amount of steel in the core of the file, making it highly puncturing and resistant to breaking. This design provides strong puncturing ability in calcified root canals, aiding in the establishment of canal pathways and laying the foundation for subsequent treatment steps.


Special treatment of the tip, taking into account both safety and piercing ability.

While the non-pointed design may not be as sharp as a pointed one, it is capable of transmitting force more effectively, ensuring smooth penetration and removal of calcified substances during endodontic treatment.
