The tightness of obturation is a key condition for successful endodontic treatment. The choice of technique depends on the anatomy of the root canal system, the shape and length of the canals, as well as the presence of branches. In modern dentistry, the following main techniques are used:
-
Lateral condensation of gutta-percha. A classical method in which a master gutta-percha cone and additional cones are inserted into the canal and compacted with special instruments. The method allows achieving sufficient tightness in cases of standard root canal anatomy.
-
Vertical condensation of heated gutta-percha. This technique involves the use of thermally softened material that is compacted step by step. It makes it possible to thoroughly fill complex areas and ensures a denser three-dimensional obturation.
-
Injection techniques using thermoplastic gutta-percha. The material is introduced into the tooth structures in a heated state, which allows filling microcanals and branches. The method is effective in cases of complex root canal anatomy.
-
Combined techniques. These combine mechanical compaction and thermal processing of the material, which increases the quality of sealing and improves the long-term prognosis.
Modern methods of root canal filling make it possible to ensure максимально dense obturation and reduce the risk of reinfection.
