Container and method for cross-linking composite materials on dental prosthesis

A method for cross-linking composite materials on dental crowns, bridges and arches by of a container comprising:

• a plurality of plate-like elements which are adapted to be stacked and clamped together;
• at least one of said plate-like elements being internal to said plurality of plate-like elements and having an area in the form of a mold capable of receiving a metallic structure whereon the elements of a dental prosthesis are to be formed, said at least one of said plate-like elements and a plate-like element that is adjacent thereto in an upward region and constitutes the top plate-like element of said container being both made of a material which is transparent to light;
• and said multiple plate-like elements being mutually connected and clamped by a plurality of traction elements which pass through coaxial holes formed in said mutually stacked plate-like elements;
• the method comprising the steps of:
• applying wax to a metallic structure for supporting a tooth, a bridge or an entire dental arch and manually sculpting the wax so as to reconstruct the shape of the intended teeth;
• inserting said metallic structure, whereto sculpted wax has been applied, in said container;
• injecting transparent silicone into said container, so as to surround said wax-covered metallic structure, embedding said structure in the silicone;
• mutually clamping the plate-like elements constituting said container in order to compress said transparent silicone and make it adhere to the coveting wax of said metallic structure, so that said silicone, by curing, takes the shape of the modeled wax, obtaining the mold;
• opening said container, removing the wax from said metallic structure and filling with composite material the space left free by the removal of said wax;
• and
• placing said metallic structure, with the composite material thereon, back into said container and exposing said container to a photopolymerization machine in order to cure said composite materials and produce the intended prosthesis.
