A suitably sized gutta-percha cone is fit into the tapered root canal preparation making sure that ‘’apical tug-back’’ has been at working length. It is simple to fit a master cone into a patent, smoothly tapered, and well-prepared canal.5-8įIGURE 4. The master cone selected should be inserted to full working length and exhibit apical tugback (resistance to displacement) upon its removal. The continuously tapered root canal preparation facilitates the fit of a suitably sized gutta-percha cone (SybronEndo/Kerr Endodontics, Orange, CA) ( Fig. These areas must be cleaned of their organic debris and bacterial contaminants by thorough irrigation protocols and then subsequently three dimensionally sealed with thermosoftened gutta percha. Microcomputed tomography 3D reconstruction of a maxillary molar, illustrating the root canal system’s complex anatomy. Post-treatment image of a maxillary central incisor showing three-dimensional obturation of an internally resorptive defect and lateral canal. Post-treatment images of a mandibular right second premolar and a maxillary central incisor which illustrates lateral canals exiting into the centres of endodontically induced periradicular lesions. Because the tip moves through a viscosity-controlled material into a tapered-like canal form, the velocity of the thermosoftened gutta percha and sealer moving into the root canal system actually accelerates as the down packing progresses, moving softened gutta percha into extremely small ramifications ( Figs. This technique allows a single-tapered electric heat plugger to capture a wave of condensation at the orifice of a canal and ride it, without release, to the apical extent by downpacking in a single, continuous movement. The Continuous Wave Of Condensation Technique Using The elementsTMfree Cordless Obturation System The Downpack and Backfill devices are available to sit in combined or single docking stations that will recharge the batteries. The elements™free Obturation System is a CORDLESS obturation system that is easy to use. The elementsTMfree Cordless Obturation System. This case report presents the retreatment of a three-rooted maxillary first bicuspid using the new elementsTMfree cordless obturation system (SybronEndo/Kerr Endodontics, Orange, CA) ( Fig. Warm vertical compaction of gutta percha using the continuous wave of condensation technique is less time consuming, provides less microbial coronal leakage,2 and adapts better to grooves and depressions of the canal walls and lateral canals than cold lateral compaction.3,4 They can be divided into two basic groups: cold lateral compaction and warm vertical compaction. Gutta-percha is the most widely used and accepted obturation material because of its biocompatibility, inertness, dimensional stability, compactability, plasticity when heated, and ease of removal for post placement or retreatment.1 There are a variety of techniques that are used to obturate the root-canal system. This is achieved by instrumentation, disinfection, and obturation of the root-canal system in three dimensions. The main objective of endodontic treatment is the prevention and/or the elimination of apical periodontitis.
