<p>The system includes filling points (10) which are formed from a thermoplastic material and include an internal heating element (24) axially aligned therein. By inserting the filling point into a prepared root canal and applying a moderate downward pressure thereon with an instrument (70) which is capable of heating the heating element in situ, the thermoplastic material can be softened to effectively seal the main root canal and accessory canals without the need to insert instruments down into the canal system.</p> |
