Prepare the root canal:

• Clean and shape the root canal using standard endodontic techniques.
• Remove the smear layer if desired, as gutta-percha can penetrate dentinal tubules better without it.

Soften the gutta-percha:

• Use a heat source to warm the gutta-percha. Electrically heated spreaders or specially designed heat carriers are recommended for this purpose.
• Ensure that the instruments are only gently warmed to avoid melting the gutta-percha.

Lateral compaction:

• Select a gutta-percha cone of appropriate size and taper.
• Fit the cone into the canal carefully, ensuring a snug fit.
• Use the sharp tip of the heat carrier instrument to laterally compact the softened gutta-percha against the canal walls.
• Apply gentle pressure and work the instrument back and forth to achieve compaction.
• Repeat this process with additional gutta-percha cones as necessary, gradually building up the root filling.

Vertical compaction (optional):

• If desired, use the blunt plugger tip of the heat carrier instrument for limited vertical compaction of the softened gutta-percha in the apical portion of the canal.
• Apply a continuous wave of heat to soften and down pack a gutta-percha cone, achieving a well-compacted obturation in the apical area.
• Additional increments of gutta-percha can be added if needed to fill the remaining portion of the canal.

Complete the obturation:

• Once the desired level of gutta-percha compaction is achieved, remove any excess gutta-percha.
• Clean the canal of any solvents or debris.
• Apply a root canal sealer of your choice.
• Fill the canal completely with a sealer using a suitable technique (e.g., cold lateral compaction, warm vertical compaction, or other preferred method).
• Ensure proper adaptation of the sealer and gutta-percha to the canal walls.
