THERMO-MECHANICAL / MC SPADDEN TECHNIQUE
 Using inverted H file – mechanical
 Disadv – can’t use in curved canals
 High chances of instrument fracture / separation
 Heat GP slightly - thermal

CONTINUOUS WAVE / SECTIONAL GP TECHNIQUE
 System B device used
 Post & core cases
 Obturating apical portion – apical 3rd
 Continuous condensation technique
 Disadv – more time consuming

CHEMICALLY PLASTICIZED / CUSTOM-MADE GP
 Indication – young permanent tooth – open apex ones- 1year after apexificatiion
 Roll 2-3 GPs on a glass slab & make one thick GP
