We have Torque control on our rotary devices because we know safe levels of torque. Programming these known conditions into our armamentarium aids successful treatment by enabling us to stay within these known parameters and out of trouble when we inadvertently exceed these ideal conditions.

Similarly, the Cork system uses technologic advances to better control our obturation parameters.

This newly designed system was engineered to increase control and efficacy in sealing root canal systems by analyzing and regulating the position, heat delivery and compaction forces during obturation. Technologic breakthroughs in each of these areas allow the CORK system to provide high levels of safe, consistent, and precise 3 – dimensional molding.

   

The CORK system employs a newly designed 3D plugger that allows for safe 3D forces of compaction. This revolutionary universal plugger conforms to individual canal anatomy creating new forces of compaction. Predicable 3D molding is accomplished by analyzing and regulating the forces generated at the face of the plugger. The 3D plugger conforms to individual canal anatomy as it moves and compacts apically. These new forces of compaction are calibrated to occur in sequence with regulated and controlled heat delivery.

The CORK system uses temperature and pressure sensors to establish and control ideal conditions for 3D molding.

   
This revolutionary plugger employs movable plates at the face of the plugger which move freely in the axial plane. By conforming to individual canal anatomy new forces of compaction are established. Sensors at the face of the plugger feedback and regulate these new forces of compaction as well as calibrate precise temperature delivery.
   

The CORK delivery device encases the gutta percha along its full length allowing for a substantially similar, direct heat transfer to the entire gutta percha cone. Calibrated forces of compaction and timed withdrawal of the delivery device occur when ideal conditions are achieved.

The CORK gutta percha is specifically formulated to mold optimally with these known temperatures and pressures.

The CORK system increases precision by measuring the position of the gutta percha to the PDL during obturation.

The CORK delivery devices are made to match conventional shaping files. The apical gutta percha is partially wrapped with a thin sheath of silver which is removed once ideal conditions for 3D molding are achieved. This design allows for both direct temperature delivery to the gutta percha along its full length and simultaneous molding while in the canal. This calibrated and timed sequence of obturation occurs when the delivery device's position is confirmed to be in an acceptable position to the PDL
   

A CORK delivery device that matches the final shaping file is fit (trimmed as needed) and sealer is applied. Final placement is confirmed with the Apex locator. The CORK 3D Plugger conforms to canal anatomy as it progresses apically and rests at the top of the gutta percha. Heat transfer is started down the delivery device.

 

   
Sensors at the face of the 3D Plugger calibrate precise, thorough heat transfer to the gutta percha. 3D forces of compaction and timed withdrawal of the delivery device occur leaving a dense homogenous seal.
