Abstract
本研究利用低溫輝光放電電漿 (glow discharge plasma) 將丙烯胺
(allylamine) 以25瓦特 (watts, W) 和50W不同能量方式接枝到氧化鋯
植體的表面,並且植入到兔子的大腿骨,最後分析接枝後的植體是否
有提升骨整合效果。
此實驗使用的氧化鋯植體,經清潔和滅菌後,在本實驗中當作
控制組。經由不同瓦數的低溫電漿25W和50W進行丙烯胺接枝後的
試樣,視為實驗組。將控制組和實驗組的氧化鋯植體植入兔子大腿
骨,並且做植體穩定度測試 (implant stability test,IST) 在植入前後做
比較;在評估實驗的氧化鋯植體和兔子的血液是否有產生交互作用,
有做血液檢測;在分析骨生長之部分,利用X光、電腦斷層
(computerized tomography) 和組織學影像檢測植入前後骨頭的高度;
在分析骨整合部分,利用組織學影像,測量不同組別螺紋間之骨植體
接觸百分比 (BIC, bone-to-implant contact)。
從IST、骨生長以及BIC實驗結果可以得知,經由25W和50W
的低溫輝光放電電漿所進行的丙烯胺接枝處理,和控制組相比,均有
很好的骨整合的效果,且植入後的植體都有很好的穩定度,但25W
從長期來說,更能促進骨生長的反應。因此,從此動物實驗我們可以
得知,選擇適合的能量在低溫輝光放電電漿進行丙烯胺的接枝,可以
有效地增加植體和骨頭間的生長,進而提升骨整合效率。
