Description
実施例1.この実施例では、ポリマー材料はポリエーテルエーテルケトン(PEEK))であり、セラミック材料はアルミナファイバー、即ち、Al2O3である。アルミナファイバーは直径約120μmであり、長さが約1−2mmである。アルミナファイバーをシランで処理するために、エタノール及び水が混合されて、95重量%エタノールと5重量%水の溶液が調製される。その後、N−(2−アミノエチル)−3−アミノプロピルトリメトキシシランのようなシランがそのエタノール溶液の約5重量%でその溶液に加えられる。次に、Al2O3ファイバーがセラミックに対するシランの重量比率が約1:100でその溶液に加えられる。その後、その溶液は約20〜30分撹拌され、セラミックフィラーはデカンテーションされ、次に約110℃で約10〜30分乾燥される。PEEKは粉体に粉砕され、200メッシュの篩で篩過される。処理されたアルミナファイバーは、次に、約30重量%のアルミナファイバーを含む混合物となるように、PEEKポリマーに加えられる。より詳細には、アルミナファイバーは、アルミナファイバーとPEEK粉体とを互いに混合した合計の約30重量%で含まれる。PEEK粉体及びアルミナファイバーは、ZSK−25二軸押出機で混練される。その後、その複合材料は加熱されて金型キャビティ内に注入されて、歯の支台歯を形成する。これを冷却し、支台歯が金型から取り出され、必要に応じて機械加工され及び/又は清浄化される。
実施例10.この実施例では、支台歯の作製方法は、アルミナファイバーが約70nmの平均サイズを有するアルミナナノ粒子に置き換えられる点を除いて、実施例1に記載した方法と同様である。アルミナファイバーは、シランが約95重量%のエタノールと約5重量%の水とを含有するエタノール溶液に混合されることを除いて、実施例1に記載したのと同様の方法でシラン化される。シラン化されると、アルミナ粒子はPEEKポリマー粉体と、約14重量%アルミナ粒子で混合される。
