Abstract
An artificial bone forming method, comprising a) a powder layer forming step (32) for forming, into a flat powder layer (6), a powder bone material (5) having biocompatibility and hardening by hydration, b) a partial hardening step (34) for jetting an aqueous solution (7) with biocompatibility to a part of the powder layer to harden a jetted portion (6a) by hydration, and c) an artificial bone forming step (36) for repeating the steps a) and b) for lamination to form a specified artificial bone (9) of a predetermined three-dimensional structure in which the hardened portions (6a) are connected to each other.
Claims12
An artificial bone forming method by a powder lamination method, comprising:
- a) a powder layer forming step for forming, a powder bone material having biocompatibility and hardening by hydration, into a flat powder layer,
- b) a partial hardening step for jetting an aqueous solution with biocompatibility to a part of the powder layer to harden a jetted portion by hydration, and
- c) an artificial bone forming step for repeating the steps a) and b) for lamination to form a specified artificial bone of a predetermined three-dimensional structure in which the hardened portions are connected to each other.
An artificial bone forming method by a powder lamination method, comprising:
- carrying out a high-temperature heat treatment in a vacuum state or an oxygen-free atmosphere to induce a reaction between biopolymers of an artificial bone formed by mixing the biopolymers, a reaction with other components, or melting.
An artificial bone forming method by a powder lamination method, comprising:
- a) a two-dimensional data creating step for sequentially moving a target bone in a predetermined direction to create two-dimensional data of a cut section,
- b) a tissue data processing step for creating data to be subjected to rapid prototyping for a plurality of tissues constituting a bone from the two-dimensional data, and
- c) an artificial bone forming step for forming an artificial bone constituted of a plurality of tissue structures by using a rapid prototyping device.
