Abstract

The invention relates to a process for filling a cavity within a tooth or mold, and also to a tool intended for the implementation of the process. The process, which is of the type in which a photosensitive resin intended to be solidified by means of photopolymerization is deposited within the cavity (3), is remarkable according to the invention in that a layer (8) of a first resin which is photosensitive at a first level of luminous radiation is deposited upon the walls (5, 6) of the cavity (3); a mass (10) of a second resin which is photosensitive at a second level of luminous radiation is deposited upon the layer (8), effectively filling the rest of the cavity (3); hardening is performed by means of the photopolymerization of the mass (10) by exposure to the second level of luminous radiation transmitted by means of a pellet (27) immersed within the mass (10); and, after hardening of the mass (10), the hardening of the layer (8) of photosensitive resin is performed by means of exposure to the first level of luminous radiation, using the pellet (27). Applications: dental treatment and care, and precision molding and casting.
