- 돼지의 해면골을 취하여 무기물화 함으로써 골이식용 해면골의 기초 본블록을 제조하는 방법에 있어서,도살한지 12시간 내의 돼지 해면골을 얻어 영하 70도의 냉동고에서 급속 냉동시킨 후 24시간 내에 원하는 크기로 다이아몬드 톱(Diamond Saw)을 이용하여 가공하는 제1단계;상기 해면골을 3차 증류수에 담가서 2시간 동안 교반 시키면서 가열하여 골수(fatty bone marrow)를 제거하는 제2단계;30% 과산화수소에 넣어 2시간 정도 교반과 동시에 가열하면서 남은 골수를 완전히 제거하는 제3단계;3차 증류수로 세척한 다음, 순도 99.9%의 알코올에 담그는 제4단계;그 후 대기 중에서 24시간이상 건조시켜 잔여 수분을 완전히 제거하는 제5단계;열처리로서, 직경 8-10cm의 튜브 형태의 전기 가열기를 이용하고, 전기 가열로는 해면골을 튜브에 넣은 후 상온에서 시작하여 분당 섭씨 10도 씩 증가시켜 섭씨 1300도 까지 승온한 후 유지하는 제6단계;섭씨 1300도에 이르게 되면 2시간정도 유지하는 제7단계; 및2시간 경과 후 전원을 끄고 상온이 될 때까지 기다리고, 전기로가 완전히 상온으로 돌아오면 튜브에서 해면골을 꺼내는 제8단계를 포함하고,상기 제6단계에서, 베타 티시피(beta-TCP)를 유지시키고자 할 때에는 튜브의 양쪽을 막는 실리콘 마개를 닫고 가열하고, 베타 티시피를 없애고자 할 때에는 실리콘 마개를 열고 가열하는 것을 특징으로 하는 골이식용 해면골의 기초 본블록을 제조하는 방법.
