1a. Shape the root canal with endo files and determine the working length. Select a master cone that closely matches the apical size.

1b. Insert Duo-Pen tip (heating condenser)into the root canal to the point 4-7 mm short of the working length. Move and set the endo stop accordingly.

2. Insert the selected master Gutta Percha cone that is coated with sealer.

3a. Place the Duo-Pen tip in the orifice of the canal and activate Duo-Pen by pressing the Operation Button. Using the activated tip, cut the middle of gutta percha cone and condense the soften material to the point 6-9 mm front the apex for about 2 seconds.

3b. Release the Operation Button to allow pen tip to cool down, while at the same time continue pushing and holding the cooled pen tip to the apex for 8 seconds. This ensures all lateral and accessory canals are filled. Activate the pen tip again by pressing and holding the Operation Button for about 1~1.5 seconds, compact the gutta percha cone to the point 4~7 mm of working length.

4. Condense the remaining material using Dia-Kondensor.




5a. Insert a gutta percha pellet into Duo-Gun and adjust to the desired preset temperature.

5b. Using Duo-Gun’s activated tip, make contact with the upper part of filled master cone in the canal, transfer heat for 3-5 seconds to soften the material.

6a. Extrude the melted gutta percha obturator into the canal.

6b. Continue flowing while withdrawing the tip from the canal.

7. Use Dia-Kondensor to compact obturation material.
