【摘要】：目的:研究氫元素存在形式與鈦表面生物學活性相關關系。方法:用硫酸和鹽酸對噴砂鈦表面進行酸蝕(酸蝕組,SLA,n=3),并對其進行加熱處理(450℃)(酸蝕加熱組,SLA+HT,n=3),分析其表面形貌、粗糙度、親水性、表面晶體結構差異。將酸蝕組及加熱組鈦片浸泡于標準模擬體液中3 d,比較其體外礦化能力。結果:酸蝕后鈦表面形成氫化鈦,加熱至450℃時鈦表面形貌及粗糙度沒有明顯改變,氫化鈦分解。模擬體液實驗結果示噴砂酸蝕組于第3天無明顯羥基磷灰石沉積,加熱組鈦表面有大量羥基磷灰石沉積。結論:噴砂酸蝕后氫與鈦形成的氫化鈦對鈦表面生物活性無明顯促進作用;加熱后氫化鈦分解,礦化能力增加。
[Abstract]:Objective: to study the relationship between the forms of hydrogen and the surface biological activity of titanium. Methods: the surface of sandblasted titanium was etched with sulfuric acid and hydrochloric acid. The surface morphology, roughness, hydrophilicity and crystal structure were analyzed. The titanium tablets of acid etching group and heating group were immersed in standard simulated body fluid for 3 days to compare their mineralization ability in vitro. Results: titanium hydride was formed on the surface of titanium after acid etching. After heating to 450 鈩，
