Abstract: The present invention relates to a high strength synthetic bone for bone replacement for increasing compressive strength and facilitating blood circulation, and a manufacturing method therefor, and provides the high strength synthetic bone for bone replacement in which calcium sulfate hemihydrate (CSH) and NaCl, in a particle state, penetrate into the pores of a porous inorganic material such as ?-tricalcium phosphate (?-TCP) and a wet treatment is performed on the same such that the CSH penetrated into the pores is combined with moisture so as to form a hydrated crystal of calcium sulfate dihydrate (CSD) to expand the volume thereof in the pores, thereby preventing the escape of a filler by physical force.

Abstract: A dental alloy contains palladium (Pd) and indium (In) for CAD/CAM machining. The dental alloy can further include one component selected from the group consisting of gold (Au), silver (Ag), nickel (Ni), cobalt (Co), and platinum (Pt). The dental alloy has a yield strength of 250 MPa to 450 MPa, breaking elongation of 2% to 8%, metal-ceramic adhesion of 20 MPa to 70 MPa, coefficient of linear thermal expansion of 14.0×10?6/K to 17.0×10?6/K, or density of 8 g/cm3 to 15 g/cm3.

Abstract: The present invention relates to a dental alloy for machining by a CAD/CAM system. In particular, the dental alloy for machining by a CAD/CAM system features a minimum usage of expensive gold and platinum by comprising gold (Au) in an amount of between 0.1% and 5.0% by weight and platinum (Pt) in an amount of between 0% and 5.0% by weight, in addition to palladium (Pd) in an amount of between 30% and 50% by weight, indium (In) in an amount of between 25% and 50% by weight, silver (Ag) in an amount of between 10% and 40% by weight and iridium (Ir) in an amount of between 0.1% and 0.3% by weight. Accordingly, compared with a conventional dental casting alloy composed of gold in an amount of between 40% and 99% the dental alloy for machining by a CAD/CAM system of the invention can be provided at a lower manufacturing cost, while offering processability equivalent to that of zirconia that can be machined by a conventional CAD/CAM system.

Abstract: A barrier membrane for guided bone regeneration and a method of manufacturing the same are provided. The barrier membrane for guided bone regeneration that is made of silver, gold, or gold alloy includes a substrate having texture including protrusions with a predetermined shape, a polymer layer formed by coating an upper surface of the substrate with polymer solution, and a bio-ceramic layer formed by coating a lower surface of the substrate. It is possible for the barrier membrane for guided bone regeneration to secure biocompatibility, exclusion and sealing of cells, space maintenance, connectivity with tissues, and easiness of using the barrier membrane which are required for guided bone/tissue regeneration (GBR/GTR).

Abstract: The present invention relates to composite materials for bone replacement comprising organic and inorganic material, more particularly to composite materials for bone replacement wherein cyanoacrylate as organic material and osteo-conductive inorganic material as inorganic material are combined. The composite materials synthesized according to the present invention, maximize the merits of organic material and inorganic material and minimize their demerits. In detail, the organic material has the maintenance of shape and the adhesive property and the inorganic material has the osteo-conductivity on a new bone. Therefore, the composite materials of the present invention can be applied to fill bone defects and replace bones, since they retain the excellent physical property.
