Master cone selection and fitting
- Select a gutta-percha master cone that matches the apical size and taper of the prepared canal.
- Trial-fit the cone to working length, checking for firm apical tug-back.
- Adjust as necessary.
- Take a working radiograph to verify apical placement of the master cone.
Pre-fitting pluggers
- Check fit of smallest condenser that will fit into the interface of the middle and apical third of the canal preparation – ideally, 3-5 mm from working limit.
- Repeat with larger condensers adhering to zone concept of middle and coronal third.
- Set stopper 1mm shy of condenser contact in canal to avoid binding/wedging and possible fracturing during condensation.
Searing the master cone
- Apply sealer to the canal and surface of master cone.
- insert master cone to working limit, avoid pumping to “piston” sealer causing apical extrusion.
- Sear off coronal portion of cone slightly below canal orifice and compact with flexible FiP tip.
- Stop activation, do not remove gutta-percha, allow tip to cool.
Remove coronal segment
Separation burst – reactivate the Fi-P tip, and retrieve the gutta-percha segment from the mass compacted.
Downpack: Progressive vertical compaction
- Use the prefit plugger to compact the softened mass into the apical matrix.
- With short firm strokes molding the gutta-percha onto the canal walls and flattening it .
- Sequence is repeated depending on volume of gutta-percha removed until apical “corkage” is achieved.
Backfilling
The Fi-G or Fi-E is set to the temperature desired based on the shape and length of the canal preparation. Put a small dollop of sealer on the coronal surface of the plug and inject a 3mm aliquot of gutta-percha.
Backfilling
Larger prefit condenser vertically compacts the increment of thermosoftened gutta-percha delivered into the canal space. Do not leave a post space if indicated at this juncture.
Backfilling
Sealer is placed on the coronal aspect of the gutta-percha mass, the injector tip is inserted into the mass and an aliquot delivered to ensure the gutta-percha fills to the floor of the chamber.
Backfilling
The largest plugger is used to compact the gutta-percha mass and seal the canal orifice.
Holistic integration
Minimally invasive techniques complement the root to crown philosophy by integrating aesthetics, function, and the health of surrounding dental structures. By focusing on the entire ecosystem of oral health, practitioners can ensure the best outcomes for their patients.
