PROBLEM TO BE SOLVED: To enable fixing of a bone flap even without use of a fixing bracket, which may exert some influence on the ecosystem because the fixing bracket is recognized as foreign matter, by forming a fixing piece for fixing the bone flap to a defective part of a biological bone, in such a manner that the fixing piece is integrated with the bone flap, when the bone flap is formed by applying cutting work to an artificial bone block.SOLUTION: When a bone flap with a fixing piece for fixing the bone flap formed from an artificial bone is formed in a defective part of a biological bone, a CT value obtained from computed tomography (CT) is converted to three-dimensional data by a computer; an artificial bone block is NC-cutting-worked on the basis of the three-dimensional data to form the bone flap; and the fixing piece for fixing the bone flap to the defective part of the biological bone is formed by being integrated with the bone flap concurrently with the formation of the bone flap. |
