<prompt> Thermoplastisized GP injection technique is indicated for obturation of:Internal resorption.Perforation.Complex root anatomy.All of the above.  <response>: Thermo plasticized GP injection technique: E.g. OBTURA 3 cooling to temperature of 71 oC same for OBTURA 2 Disadvantage: voids can be seen if vertical compaction not combined. Indication: Obturation for Internal resorption Perforation Complex root anatomy most important Open apex obturation done with apical barrier.
