Conventional endodontic microsurgery resects the apex. Zero apicectomy does not. Preserving the full root keeps the periodontal ligament attachment and lets bone regrow along its natural anatomy, rather than against a cut face.

A cold intracanal irrigation protocol applied at the end of treatment. It reduces the inflammatory response that drives post-operative pain, in a procedure patients fear precisely because of that pain.

Irrigant does not reach where anatomy is closed to it. Introducing a partial vacuum into the shaped canal pulls solution into the isthmuses and lateral anatomy that flow alone never touches. Developed with Alfredo Iandolo.
