註解: 美國하 -바 드 會議勸吿는 우리들 齒科임프란트 施術者에게 하나 의 임프란트 施術가이드 라인이다. 임프란트 施術을 하였으나 骨이 파괴되 지 않은 施術이 우리에게 必要하다. 모든 임프란트의 利得과 缺點一. 이것 은 우리 에게 주는 指針이 기도 하고 事?? *防은 勿論 임프란트 齒科醫學 에 큰 意義을 줄것이 며 發展에 크게 기여 할것이 다. 이 原稿는 美國厚生省 ( 우리나라 保健社會部에 해당 ) 이 發行한 것으로 그 序論과 現在 많은 施 術이 이루어지고 있는 骨內 임 프 란 트 (刀型 임프란트) , (姜弘求 博士 : 本會 總務理事 ) 에 이어 第 2 編인 骨膜下 임 프란트에 關한것을 李鳳遠 博 士 ( 本會 器材理事 ) 가 발췌정리 手苦하였다.

F.D.B.I.를 利用한 全領(上.下領) 아 - 치 型 繼續 橋義歯 回復症例. 가톨릭 医科大学 歯科学 教室 聖母症院 歯科
朴金沫,李鳳遠,表拥 대한치과이식임플란트학회 1981 The Korean Academy of Implant Dentistry Vol.2 No.1
In the past some decades, considerable developm ent has been achieved in the field of oral implantology. Especially, in the 1960’ s and 1970’ s the developm ent of materials with biocompatib ility and improved physical propertie s gave renew ed impetus to the use of dental implants. The authors practiced fixed crown and bridge work for upper and lower complete arch after implantation of Free Design Blade Implant on the lower bilateral free -end saddle areas and upper left canine, 1st premolar and 2nd premolar missing area. Upper blade was designed to have one head and lower blades were double heads because of long span. Now that about two years have passed, not only find authors no inflammation a round the blade heads, but patient is satisfied with the results —esthetic and masticatory function.

犬下顆骨에 移植된 TITANIUM 大工齒牙의 周圍組織反應에 關한 病理組織學的 研究 가톨릭 醫科大學 齒科學教室
崔牧均,表雅,李鳳遠,朴金沫 대한치과이식임플란트학회 1984 The Korean Academy of Implant Dentistry Vol.5 No.1
The authors observed the histopathological tissue reaction to the Free Design Blade-vent Implants made of pure titanium in the mandibles of dogs. The mandibular left 2nd, 3rd premolar teeth in 4 healthy dogs (4045kg B.W.) were removed. Twelve weeks after the extraction, the F.D.B.I. were implanted into the extracted premolar areas.S ix months after the implantation, the tissue blocks containing the implants were removed. These block sections were fixed in 10% neutral buffered formalin for 2 days and decalcified in 5% trichloracetic acid. The buccal side of the blocks were removed with a knife and F.D.B.I. were detached to buccal from the tissue blocks • Then the implants were prepared and examined in scanning electron microscope. The tissue blocks were embedded by paraffin embedding method and then sectioned by 7m. They were stained with hematoxylin and eosin. The obtained results were as follows: 1. The rete pegs of the epithelium around the sulcus were increased and the inflammatory calls were infiltrated in the connective tissue beneath the sulcular epithelium. 2. There was no fibrous capsule between the titanium and the bone. 3. Compact bone and spongy bone were formed around the titanium. Haversian system, new bone formation by osteoblast, and bone resorption by the osteoclast were observed in the bone. There was no osseous abnormality. 4. On the scanning electron microscope observation, epithelial cells were attached on the neck of titanium implants, that is, mechanical stress results in tearing within epithelium (or periimplant cervical tissue), rather than in a clean separation of the epithelium from implant surface. 5. From this study, it is concluded that force of epithelial attachment of titanium implants is almost equal to the natural teeth and that titanium implant is biocompatible with the living tissue.
