Patent

CA 2137918

There is provided a procedure to maintain an otherwise whole tooth, from which the nerve has been removed by carrying out a procedure which includes inserting a thin flexible post (11), preferably formed of a light-transmitting, physiologically inert material, to the full depth of a prepared relatively narrow tooth nerve canal (8), which has previously been sealed at its bottom with gutta percha (12). The post is then surrounded by a film of a composite-filler or sealant (16), which is preferably light-curable, rotating the post while supporting and sealing the walls of the canal. The post is sufficiently flexible as to be able to follow the curvature of the canal, which may retain a slight natural curvature. The composite filler or sealant is then cured, preferably by an optical radiation carried through the preferably transparent post.
