APEXUM procedure

This procedure is based on a device that removes the chronically inflamed periapical tissues through a root canal access by a procedure that is minimally invasive compared with open-flap apical surgery

 Apexum  instrument kit consists of

The Apexum kit consists of two devices, the Apexum NiTi Ablator and Apexum PGA Ablator.

The Apexum NiTi Ablator consists of a specially preshaped Nitinol wire. One end is bent and is designed to enter the periapical tissues through the root canal and apical foramen, whereas the other end has a latch-type connector to allow its attachment to a low-speed contra-angle handpiece. The bent part is initially concealed in a straight super elastic Nitinol tube that serves as a sheath allowing its introduction up to the apical foramen. When pushed, the wire emerges from its sheath and through the apical foramen and resumes its preshaped form. The special retrograde design of the bent part allows it to rotate in the periapical soft tissues at 200 to 250 rpm and coarsely grind them while being deflected from the surrounding bone.

The second device is the Apexum PGA Ablator, built from a Nitinol shaft. It has a bioabsorbable  filament is attached, which is designed to enter the periapical bony crypt and rotate at 5,000 to 7,000 rpm, turning the tissue that was initially minced with the NiTi Ablator into a thin suspension that may be flushed through the root canal.
