Estimating the term…
The invention concerns an insert for filling the dental canal comprising means for anatomically and physiologically filling up the root canal 1, comprising a ductile and resilient core 10 made of a polymerised composite material, sheathed in one or several sleeves 14, 15 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 1. 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 17 of the insert which emerges from the root canal 1, 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.
An insert for filling a dental canal comprising a ductile or malleable core made of a composite material in polymerised state, said core being sheathed in at least one sleeve made of a composite material pre-impregnated with resin, said composite material of said at least one sleeve being in a first pasty state prior to polymerisation such that the insert is ductile and malleable before and during its introduction into the root canal, wherein said composite material of said at least one sleeve is able to be polymerised with cross-linking to change the composite material to a second polymerised state after the insert has been inserted in said canal.
