Abstract
(EN)
An appliance (20) for use in conjunction with the obturation of prepared root canals employing a rigid carrier member (22) coated with a thermoplastic material (29) comprises an instrument (40) having a barrel (41), a movable plunger (42), and an orifice (48), and a quantity of the thermoplastic material (29) within the barrel. The orifice has a diameter greater than the distal end (30) of the rigid member, the member being insertable through the orifice and into the thermoplastic material whereby upon extrusion of a quantity of the thermoplastic material from the barrel, the rigid member is provided carrying a coating of thermoplastic material.

Dispositif (20) s'utilisant en association avec l'obturation de canaux radiculaires préparés, au moyen d'un élément de support rigide (22) revêtu d'un matériau thermoplastique (29) et comprenant un instrument (40) pourvu d'un cylindre (41), d'un piston mobile (42) et d'un orifice (48), ainsi que d'une quantité déterminée dudit matériau thermoplastique (29) à l'intérieur du cylindre. L'orifice possède un diamètre plus grand que l'extrémité distale (30) de l'élément rigide, ledit élément rigide pouvant s'introduire dans l'orifice et dans le matériau thermoplastique, et, de ce fait, lorsqu'on extrude une certaine quantité dudit matériau du cylindre, ledit élément est recouvert dudit matériau thermosplastique.
