摘要

Method for the production of a biologically active prosthetic device for the reconstruction of bone tissue and the prosthetic device itself. The invention relates to a method for producing a biologically active prosthetic device for the reconstruction of bone tissue comprising the steps of: CAT (Computed Axial Tomography) scanning of the patient and obtaining a three-dimensional electronic model (1) of the bone and a defective bone (2) to be reconstructed; prototyping production of a resin model prototype (3) of the patient bone area involved, forming a model (4) of the defective patient bone to be reconstructed; constructing a negative mold (5), producing a semi-finished sintered ceramic product with interconnected and controlled porosity, said semi-finished product being made with dimensions and shape slightly larger than the defective bone; Mechanical processing and manual finishing of the sintered semifinished product to obtain the precise shape and dimensions of the defective bone, the invention also relates to the prosthetic device obtained using the method described above.
