3500 Hasselt Belgium www.ontzenuwen.be. It is a retreatment of a Thermafill case……they are not always easy, the failures are usually a reflection of improper shaping which results in stripping of the gutta percha from the carrier………the bottom line is that the difference between a silver cone and gutta percha and an acrylic carrier and gutta percha is “not so much”. The gravitometric density of the obturating material is a factor in the success of the endodontic procedure – as concluded by the Toronto Studies of Dr. Friedman and his post-doctoral students…..you can’t obturate anything in two dimensions, but you can obturate badly in three dimensions if there is an obstructive entity in the rheologic flow of the obturating material………word to the wise.
