Abstract: A method of preparing a dental implant and prosthetic device in-house at the site of a dental procedure from a preparation kit, without requiring an external third-party lab to prepare the final prosthetic device. The kit contains a porous block, a thermoset polymeric resin, and an initiator, where the resin and initiator are both packaged in substantially airtight and substantially opaque packaging. The resin and initiator are combined together to form a resin mixture which is then infiltrated into the pores of the porous block to form an esthetic material. A digital scan of at least a portion of a patient's jaw is used to provide the desired shape of the dental device to a cutting mechanism, which then cuts the filled or un-filled porous block based on the shape provided to it from the digital scan.

Abstract: The invention relates to a method for making metallic and/or non-metallic products 2, in particular dental products, by freeform sintering and/or melting, in which the products 2 are fabricated layer by layer from a material 5 that is applied layer by layer by means of a computer-controlled high-energy beam 7,in particular a laser or electron beam.

Each of said positions P1 to P6 is initially heated during the first irradiation to a temperature below the melting point Tmelt of the material 5, and during the mth irradiation to a temperature above said melting point and is completely melted over the entire thickness of the layer in such a way that the material (5) fuses at said position to the layer thereunder. The invention also relates to an apparatus for performing said method.

Abstract: It is intended to provide a scaffold whereby a bone and a metallic material can three dimensionally form together a stereoscopic binding layer. Thus, a geometric space sufficient for cell actions is provided. As a result, the time required for the formation of a stereoscopic bond can be shortened and, moreover, a bond can be self-repaired owning to cell actions even in the case where a pair of the bond is injured by a wound, etc. As a material for designing a scaffold, titanium fibers of less than 100 ?m in size and having an aspect ratio of 20 or more are selected. Then these fibers are entangled together to form a layer which is integrally fixed by vacuum sintering to a periphery surface of the various implant bodies, and coated with apatite. The fact that the layer contains spaces of an excellent ability to induce a biological hard tissue and fix the same is proved by the material, in which the layer is fixed to the periphery of an implant.
