Rationales for retreatment may be an endodontic failure during initial procedure, a re-infection in the tooth (new decay), a broken crown, a treated tooth that sustains a fracture or in case an existing restoration must be redesigned.
The retreatment involves re-accessing the pulp chamber, removing the three-dimensional intra-canal obturation materials before proceeding to the the new roots treatment.
Removing the obturation materials is considered as a tricky operation but remains essential to achieve endodontic retreatment success. It generally requires the use of solvent which are unfortunately toxic for the patients.
The MicroMega REMOVER file has been specifically designed to remove the Gutta-Percha obturation material during a nonsurgical endodontic retreatment.
As the essential piece for the retreatment, MicroMega REMOVER mechanically removes the Gutta-Percha material from the root canal, without the use of solvent.
After the Gutta-Percha been removed from the root canal using MicroMega REMOVER, the practioner may proceed with the canal re-shaping, following his usual instruments and shaping scheme.
