Abstract
Description
(a)酸化ジルコニウムの粒子を加圧下で該充填材の外側区域に噴射加工する工程、
(b)前記充填材の噴射加工した外側区域を、硫酸及びフッ化水素酸を含んでなる酸組成物で化学的に処理する工程、及び
(c)前記噴射加工した、化学的処理した充填材の外側区域を温度200〜450℃で15〜120分間加熱することにより、熱処理する工程、
を含んでなる、手順を提供する。
市販の純粋チタン製の、ネジ山を切った円錐−円筒形骨内Defcon TSA充填材を、125μmのジルコニア粒子で、圧力6気圧で、出口オリフィスを処理する表面に対して直角に、距離2cm〜3cmで配置し、噴射加工した。噴射加工の後、加圧空気で清掃し、次いで純水中に超音波下で10分間浸漬した。次いで、これを、圧縮空気を使用して乾燥させた。
<形態>
例1で得られた表面形態を、表面顕微鏡写真及び共焦点顕微鏡による粗さの測定により、試験した。
表面顕微鏡写真
表面の顕微鏡写真撮影は、JEOL JSM 840走査電子顕微鏡で、15kV走査光線で行った。
粗さの3D測定は、the Department of Optics of Escuela Tecnica Universitaria de Terrasa (Polytechnic Universiity of Catalonia)により開発されたPLμソフトウエアに接続された共焦点顕微鏡により行った。測定は、800μmのGaussianカット−オフフィルターによるDIN 4768標準により行った。
表面化学組成の分析は、2種類の異なった技術、すなわちエネルギー分散型X線分光法(EDS)及びX線光電子分光法(XPS)、により行った。
この技術により、厚さ約1μmの表面の組成を、高空間分解能で定量測定することができる。EDSにより、ホウ素とウラニウムの間の原子量を有する原子の存在を検出し、試験している表面上にある原子を定量することができる。
XPS分析は、Barcelona UniversityのScientific−Technical ServicesのESCA及びTEM Unitにより行った。これらの結果を表1に、様々な歯科用充填材の文献(Wieland et al.、「チタン充填材表面の化学組成及び特徴の測定及び評価(Measurement and evaluation of the chemical composition and topography of titanium implant surfaces)」、Bone Engineering,ch.14(2000)J.E.Davis eds.、Massaroら、「市販チタン歯科用充填材の表面特性の比較試験、Part I、化学組成(Comparative investigation of the surface properties of commercial titanium dental implants. Part I: chemical composition)」、J Mat Sci:Mat in Medicine(2002)13:536−548)に引用されているXPS分析と比較して示す。
例1に記載する方法と類似の方法により処理したチタン試料(直径5mmの商業的に純粋なチタンディスク)の生物学的評価の研究が、063−13研究グループ(Pharmacology Dept.Faculty of Medicine and Odontology, Santiago de Compostela University,Spain)により行われた。
