Abstract:
1. An obturator for sealing an apical end of a prepared root canal, the obturator comprising a delivery device for delivering a plug of unheated filler material into a prepared root canal and a holder for the delivery device; the holder comprising: the delivery device further comprising a bed at a distal end of said shaft; said shaft and said bed comprising heat conductive and electrically conductive material; said bed having an inner concave surface defining a filler material receiving surface and an outer convex surface opposite said inner surface; a plug of thermoplastic biocompatible filler material being mounted to said bed inner surface such that said bed outer surface opposite said filler material is substantially free of biocompatible filler material; wherein said delivery device shaft is shaped to be received in said internal channel of said holder such that when said delivery device is mounted to said holder, at least a portion of said delivery device shaft is internal of said holder; and wherein, when said delivery device is received in said holder, said delivery device shaft is in heat transfer communication with said heating circuit such that upon activation of said heating circuit, heat will be transmitted along the delivery device shaft to heat the filler material mounted to the bed of the delivery device; and wherein when said delivery device is received in said holder, said delivery device shaft is in electrical communication with said portion of said apex locating circuit; such that said delivery device also forms a portion of said apex locating circuit.
