Abstract:
1. A method for manufacturing a biomedical device for fitting bone defect, said biomedical device having an osteoconductive first area, at the periphery of the biomedical device, with a controlled porosity and a second area with a porosity, the ratio of the porosity of the second area to the porosity of first area being equal or less than one, and the device being produced by a laser technology from a powder comprising a material selected from the group consisting of ceramics, metals, metal alloys, bioactive glasses, lead zirconatetitanate, biocompatible polymers, and mixtures thereof, wherein the laser is a pulsed laser or continuous laser of 100 to 250 watts the laser power of the laser beam being adjusted at 1 to 25% of the total power of the laser and the progression speed of the laser beam ranging from 0.01 and 50 mm/s, and wherein an image of the defect is performed, from this image, a virtual object is designed with a computer-aid designed software, optionally, a scale model is performed, the biomedical device is manufactured by a laser technology comprising layering a powder of particles onto a plate (
