These high-quality pluggers are shaped to closely match the final root canal preparation. This maximises condensation forces on the softened obturation material without placing undue stress on the root canal system. As the Elements obturation unit and the System B unit maintain a constant temperature during treatment, the obturation material is not over-softened by the Buchanan plugger and the warm mass fills lateral canals as easily as it seals apically. When you disengage the heat, the pluggers cool instantly and can therefore be separated easily from the obturation material.
