| Abstract ： | 「緒言」 歯周疾患により失われた歯周組織の回復を図るため骨移植法や, GTR法など, 生体材料を使用した歯槽骨再建療法が行われている. このような人工骨移植材を材料と周囲組織の関係から分類すると 1) 生体許容性材biotolerant material 骨組織と移植材の間に厚い線維組織が形成され, 骨とは直接接合しないもの(bone cement, stainless steel) 2) 生体不活性材bioinert material 骨組織と移植材の間に薄い線維組織が形成され, 骨と接合する場合がある(carbon material, alumina) 3) 生体活性材bioactive material 骨と移植材が化学的に結合する(bioglass, hydroxyapatite) 4) 生体内崩壊材biodegradable material 組織内において崩壊し, 新性骨と置換する(tricalucium phosphate, 低結晶のhydroxyapatite)ものに分類される. |

| Abstract ： | Abstract : Tricalcium phosphate (TCP) granules was implanted in artificially created periodontal bone defects (Artificial bone defect). After seven, 30 and 90 days, animals were sacrificed, then vascular corrosive resin cast method, scanning electolon microscopy and histological observation using India ink injection method were done. (Experimental protocol was same as previous report of HAP implant) The results were as follows ; 1) After 7 days, Artificial bone defect was filled by TCP and newly formed blood vessels was observed. New bone formation showed only the bottom regions in the Artificial bone defect. 2) 30 weeks later, TCP and newly formed bone include many blood vessels filled in the Artificial bone defect. Connection of TCP granules and new bone was not tightly compare to HAP, Owing to existence of vascular which played to resolve the granules and form the bone. 3) 90 days later, bone trabecular pattern was formed in the Artificial bone defect where had many blood vessels and TCP granules, but these granules were smaller than before periods. We conclude the TCP make new bone formation by osteoconduction, and the character of TCP degradation is implicate the tissue remodeling which is materials resorption and bone formation, rather than osteoconduction. |
