Abstract
The invention concerns an insert for filling the dental canal comprising means for anatomically and physiologically filling up the root canal,, comprising a ductile and resilient core,made of a polymerised composite material, sheathed in one or several sleeves,made of a composite material pre-impregnated with resin, being in a first pasty state previous to polymerisation so as to make the insert flexible and malleable before and during its introduction into the root canal,Said material is then polymerized at will by cross-linking means to be in a second polymerized state after the insert has been introduced in said canal. The upper part,of the insert which emerges from the root canal,can advantageously be used as prop or pivot for a coronal reconstitution. Thus, the same material is used for filling the root canal and for reinforcing the residual structures of the tooth. The canal obturator and the anchoring pivot are made of one and the same material.
