Abstract: PROBLEM TO BE SOLVED: To provide implant of high affinity with living bodies used by dentists and orthopedists as a substitute device for hard tissues, and also provide a method of manufacturing the same. SOLUTION: The process of preparation of the implant comprises conversion of the load from a uniaxial pressing apparatus to a load from two laterally facing directions using a load transmitting mechanism of a wedge. This is subjected to plastic deformation in a mold by simultaneous thermal pressing of both bottom faces of the processed material consisting of titanium or its alloy. Then, biologically active ceramics, for example hydroxyapatite, is uniformly squeezed into the whole side of the processed material.
