摘要:
A method for obtaining a composite material including an aqueous solution of pectin and a suspension/solution of calcium phosphate mixed together, wherein said solution of pectin cross-links with a portion of the calcium obtained from the solution of calcium phosphate and wherein a portion of the calcium phosphate in suspension remains as inorganic phase and composite materials obtained by this method.
摘要:
The method for coating prosthesis elements (P) that have a concave surface (7; 107; 207; 307; 407; 507; 607; 707; 807) and a corresponding convex counter surface (8; 108; 208; 308; 408; 508; 608; 708; 808), comprises: arranging in at least said concave surface shaped gripping means (R) for gripping coating means (9); coupling coating means (9) with said shaped gripping means (R), said coupling comprising coating said concave surface (7; 107; 207; 307; 407; 507; 607; 707; 807) with said coating means (9) temporarily being in a mouldable state obtaining moulded coating means (9); making said moulded coating means (9) solidify and adhere firmly to said shaped gripping means (R).
摘要:
Procedure for the manufacture of metal articles with laser, comprising the following phases: prepare at least a metal substrate (17); deposit on said substrate (17) at least a layer (18) of commercially pure zirconium or its alloys in the form of powder (7); cut said layer (18) with at least a laser beam (10) having a ratio between power and translation speed between 0.12 -0.20 W.s/mm.
摘要:
Method for the realization Hof a calcium phosphate-based biomaterial in form of granules and/or agglomerates of re-absorbable granules which can be used in the biomedical industry as, e.g., bone fillers, for increasing the bone mass, as a sealing for the internal orthopaedic prosthesis, for releasing drugs and/or medicaments and/or other substances beneficial for the organism. A calcium phosphate-based biomaterial in form of granules and/or aggregates thereof obtained according to such method.
摘要:
Method for providing a biocompatible bone implant adapted to fill a bone cavity or lacuna including the steps of providing granular elements in form of granules and/or granule aggregates, providing at least one primary polymeric solution including a biopolymer, at least partly coating the granular elements with the primary polymeric solution, obtaining coated granular elements including a biopolymer coating, providing a cross-linking solution, dipping the coated granular elements in the cross-linking solution, waiting a period of time referred to as “jellification time” of between 30 seconds and 1 hour, in which during said waiting step there occurs the cross-linking of the biopolymer coating of the granular elements with the cross-linking solution and the jellification of the coating, with the aim of obtaining a cohesive biocompatible implant including granular elements and a bio-reabsorbable biopolymer gel; biocompatible bone implant obtained through such method.
