【選択図】なし
Description
該非晶質粉末(a2)は、シリカ系微粒子と、該シリカ系微粒子の表面を被覆する、ジルコニウム原子、ケイ素原子及び酸素原子を含有する酸化物とを含んでなり、
該水溶性金属塩(a1)が、該非晶質粉末(a2)の酸化物の被覆上に分散している、歯科用組成物である。
前記水溶性金属塩(a1)は、金属フッ化物、アルカリ金属炭酸塩、アルカリ土類金属炭酸塩、アルカリ金属リン酸塩、アルカリ土類金属リン酸塩、アルカリ金属塩化物、及びアルカリ土類金属塩化物からなる群より選ばれる少なくとも1種の金属塩であることが好ましい。
前記非晶質粉末(a2)のシリカ系微粒子は、2〜300nmの平均粒子径を有することが好ましい。
前記複合粉末(A)の平均粒子径が、0.5〜100μmであり、かつ比表面積が50〜300m2/gの範囲にあることが好ましい。
前記複合粉末(A)の屈折率は、1.48〜1.60の範囲にあることが好ましい。
〔X線回折の測定条件〕
2θ:10〜70°
スキャンスピード:2°/min
管電圧:30kV
管電流:130mA
(1)酸化ジルコニウム水和物を含む水溶液に、アルカリ金属の水酸化物と過酸化水素を添加して攪拌することにより、該酸化ジルコニウム水和物を解膠して溶解させた混合水溶液を調製する工程。
(2)平均粒子径2〜300nmのシリカ系微粒子を水に分散させたシリカゾルに、前記工程(1)で得られた混合水溶液と珪酸液の水溶液を撹拌しながら添加する工程。
(3)前記工程(2)で得られた混合水溶液を陽イオン交換樹脂で処理して脱アルカリする工程。
(4)前記工程(3)で得られた混合水溶液を反応容器中に入れて、100〜350℃の温度で水熱処理して、シリカ系微粒子の表面が少なくともジルコニウム原子、ケイ素原子及び酸素原子を含有する酸化物で被覆された非晶質粉末(a2)が分散したゾル溶液を調製する工程。
このアルカリ金属水酸化物は、前記酸化ジルコニウム水和物に対して、モル比(M2O/ZrO2・xH2O)が1/1〜10/1となるような割合で添加することが好ましい。
また、前記工程(1)で使用される過酸化水素(H2O2)は、前記酸化ジルコニウム水和物に対して、モル比(H2O2/ZrO2・xH2O)が5/1〜30/1となるような割合で添加することが好ましい。
この珪酸液の水溶液の中でも、pHが2〜4の範囲にあり、ケイ素成分の含有量がSiO2換算基準で0.5〜5重量%の範囲にあるものを使用することが好ましい。
また、前記シリカゾル中へのこれらの添加量は、該シリカゾル中に含まれるシリカ系微粒子上への被覆度合いによっても異なるが、該シリカ系微粒子をSiO2-(2)で表したとき、重量比{(ZrO2/SiO2-(1))/SiO2-(2)}が7/100〜15/10の範囲にあることが好ましい。なお、前記シリカゾルは、これらを添加する前に、あらかじめ70〜95℃の温度に加熱しておくことが好ましい。
強いアルカリ性を呈する前記混合水溶液-(1)の添加に伴い、前記混合水溶液-(2)中のpHは経時的に高まるので、該混合水溶液のpHが11に近づいた段階で、前記混合水溶液-(1)と前記珪酸液の添加を中止することが望ましい。ここで、前記pHが11を超えると、前記シリカゾル中に含まれるシリカ系微粒子がアルカリにより混合水溶液-(2)中に溶解し始めるので、好ましくない。
よって、pHが11になった段階で前記混合水溶液-(2)及び前記珪酸液の添加が完了していない場合は、以下に述べる工程(3)に処して脱アルカリした後、この操作を再度又は繰り返して行うことが好ましい。
また、この工程では、前記混合水溶液-(2)を該混合水溶液のpHが7.0〜10.0となるように脱アルカリ処理することが好ましい。
(5)上述のような方法で製造された、非晶質粉末(a2)が分散したゾル溶液に、別に用意した水溶性金属塩(a1)の水溶液を加えて均一な混合物とする工程。
(6)該混合物から水などの溶剤を除去して乾燥する工程。
従って、非晶質粉末(a2)の焼成体も、前記酸化物の被覆を有する複数のシリカ系微粒子が、当該酸化物の被覆において連結して凝集した、多孔質状の粒子構造を有し得る。焼成工程で得られた焼成体は、必要に応じてすり鉢やボールミル等を用いた粉砕工程に供してその粒子径を調整するとよい。
このような表面処理により、複合粉末(A)と重合性単量体(B)とのなじみが改善されて分散性及び密着性を向上させることができ、その結果硬化物の機械的強度を高めることができる。また、複合粉末(A)からのイオン徐放量を適切な速度にコントロールすることができることがある。
(イ)一官能性(メタ)アクリレート
メチル(メタ)アクリレート、イソブチル(メタ)アクリレート、ベンジル(メタ)アクリレート、ラウリル(メタ)アクリレート、2−(N,N−ジメチルアミノ)エチル(メタ)アクリレート、2,3−ジブロモプロピル(メタ)アクリレート、2−ヒドロキシエチル(メタ)アクリレート、6−ヒドロキシヘキシル(メタ)アクリレート、10−ヒドロキシデシル(メタ)アクリレート、プロピレングリコールモノ(メタ)アクリレート、グリセリンモノ(メタ)アクリレート、エリトリトールモノ(メタ)アクリレート、N−メチロール(メタ)アクリルアミド、N−ヒドロキシエチル(メタ)アクリルアミド、N−(ジヒドロキシエチル)(メタ)アクリルアミド、(メタ)アクリロイルオキシドデシルピリジニウムブロマイド、(メタ)アクリロイルオキシドデシルピリジニウムクロライド、(メタ)アクリロイルオキシヘキサデシルピリジニウムクロライド、(メタ)アクリロイルオキシデシルアンモニウムクロライドなどが挙げられる。
エチレングリコールジ(メタ)アクリレート、トリエチレングリコールジ(メタ)アクリレート、プロピレングリコールジ(メタ)アクリレート、ネオペンチルグリコールジ(メタ)アクリレート、1,6−ヘキサンジオールジ(メタ)アクリレート、1,10−デカンジオールジ(メタ)アクリレート、ビスフェノールAジグリシジル(メタ)アクリレート(2,2−ビス[4−〔3−(メタ)アクリロイルオキシ−2−ヒドロキシプロポキシ〕フェニル]プロパン、通称BisGMA)、2,2−ビス〔4−(メタ)アクリロイルオキシエトキシフェニル〕プロパン、2,2−ビス〔4−(メタ)アクリロイルオキシポリエトキシフェニル〕プロパン、2,2−ビス[4−〔3−((メタ)アクリロイルオキシ−2−ヒドロキシプロポキシ〕フェニル]プロパン、1,2−ビス〔3−(メタ)アクリロイルオキシ−2−ヒドロキシプロポキシ〕エタン、ペンタエリトリトールジ(メタ)アクリレート、[2,2,4−トリメチルヘキサメチレンビス(2−カルバモイルオキシエチル)]ジメタクリレート(通称UDMA)などが挙げられる。
トリメチロールプロパントリ(メタ)アクリレート、トリメチロールエタントリ(メタ)アクリレート、テトラメチロールメタントリ(メタ)アクリレート、ペンタエリスリトールテトラ(メタ)アクリレート、ジペンタエリスリトールヘキサ(メタ)アクリレート、N,N’−(2,2,4−トリメチルヘキサメチレン)ビス〔2−(アミノカルボキシ)プロパン−1,3−ジオール〕テトラメタクリレート、1,7−ジアクリロイルオキシ−2,2,6,6−テトラアクリロイルオキシメチル−4−オキシヘプタンなどが挙げられる。
製造した粉末の粒子径の測定には、レーザー回折式粒度分布測定装置(SALD−2100:島津製作所製)を用いた。分散媒には、0.2%ヘキサメタリン酸ナトリウム水溶液を用いた。
湯浅アイオニクス社製カンタソーブQS−13型を用いて測定した。測定原理はBET法である。
アッベ屈折計を用い、ナトリウムのD線を光源として、イオウの溶解したジヨードメタン、1−ブロモナフタレン、サリチル酸メチル、ジメチルホルムアミド等を液体として液浸法で測定した。なお、各実施例及び比較例で用いた重合性単量体(B)の重合体の屈折率の測定には、2,4,6−トリメチルベンゾイルジフェニルホスフィンオキサイド(TMDPO)を1重量%溶解した重合性単量体を脱泡後、光重合させて得た硬化物を、5mm×10mm×20mmの直方体に成形したものを試験片として用いた。
走査型電子顕微鏡S−4000(日立製作所社製)を使用し、複合粉末(A)に含まれる各構成成分の該複合粉末(A)中における微細な相分散状態の観察を2次電子像の観察により行った。
複合粉末(A)を含有する歯科用組成物の重合硬化物は、ダイヤモンドペーストを用いて鏡面研磨し、複合粉末(A)に含有される水溶性物質が溶出しないように、ヘキサンを用いて研磨面を洗浄した。複合粉末(A)の微細構造の観察では、サンプルの研磨表面をカーボン蒸着し、電子銃の印加電圧を5keVとした。非晶質粉末(a2)と水溶性金属塩(a1)の分散状態の観察では、2次電子の検出強度差を利用するが、2次電子の検出強度差が最適になるようサンプル表面への導電性物質の真空蒸着条件や、電子銃の印加電圧を調整した。また、併せて複合粉末(A)中の水溶性金属塩(a1)の結晶からなる相の最長の長さ(長径)と最短の長さ(短径)(nm)を、電子顕微鏡写真上で任意に100点測定した。100点のうち最長の長径を最大粒子径とした。また長径と短径の平均値を粒子径とし、測定した100点の平均値を平均粒子径とした。
歯科用組成物の硬化物の試験片(2mm×2mm×30mm)を作製した。試験片は、37℃の水中に24時間浸漬し、万能試験機(インストロン社製)を用いて、クロスヘッドスピードを1mm/minに設定して、支点間距離20mmで3点曲げ試験法により曲げ強さを測定した。
歯科用組成物の硬化物の円盤状試験片(20mmφ×1.0mm)を作製した。分光測色計(ミノルタ社製、CM−3610d)を用いて、C光源測色視野2度で、試験片の背後に標準白板を置いて色度を測定した場合の明度(L1)と、同じ試験片の背後に標準黒板を置いて色度を測定した場合の明度(L2)を測定し、両者の差(ΔL=L1−L2)を算出して、透明度の指標とした。ΔLの値が大きいほど硬化物の透明度が高いことを意味する。
厚さ1mm、直径18mmの歯科用組成物の硬化物円盤を作製し、表面をSiC研磨紙#1000で研磨して、pH7のリン酸バッファー中に浸して、37℃の恒温漕中に1か月間保管した。1か月間のフッ素イオンのリン酸バッファー中への放出量を、フッ素電極を接続したデジタルイオンメーター920−A(オリオン社製)で測定した。なお、歯科用組成物からのイオン放出量は、前記硬化物円盤の円形表面の単位面積当りでのフッ素イオンの放出量(μg/cm2)として表わした。
(1)非晶質粉末(a2)が分散したゾル溶液の調製
オキシ塩化ジルコニウム250kg(ZrOCl2・8H2O、太陽鉱工(株)製)を温度15℃の純水4375kgに加えて攪拌し、オキシ塩化ジルコニウムを溶解させた。
前記オキシ塩化ジルコニウム水溶液に、15重量%濃度のアンモニア水250Lを攪拌下でゆっくりと添加して、15℃の温度条件下で前記オキシ塩化ジルコニウムの中和反応を行い、酸化ジルコニウム水和物の沈殿を含むスラリーを得た。このスラリーのpHは8.5であった。
次いで、このスラリーを濾過し、得られたケーキ状物質を純水で繰り返し洗浄して、前記中和反応での副生物や未反応物などを除去した。その結果、酸化ジルコニウム水和物をZrO2換算基準で10重量%含み、残余物が水分であるケーキ状物質860kgを得た。
さらに、この混合水溶液を攪拌しながら1時間、放置し、前記酸化ジルコニウム水和物を解膠して水溶液中に溶解させた。次いで、純水を冷凍して得られた氷水39991gを加えて、発熱反応によって温度が上昇した前記水溶液を30℃以下の温度に冷却した。これにより、ZrO2換算基準でジルコニウム成分を0.5重量%含み、pHが約11の混合水溶液102400g(以下、調製液1Aという)を得た。
次いで、平均粒子径12nmのシリカ微粒子を30重量%含むシリカゾル3336g(触媒化成工業(株)製 SI-30)に純水47900gを加えて十分に撹拌し、シリカ微粒子濃度2重量%のシリカゾル51236gを得た。
次いで、前記調製液1B-(1)を陽イオン交換樹脂(三菱化学(株)製、SK1BH)で処理して脱アルカリした。これにより、pHが約9.5の混合水溶液117250g(以下、調製液1C-(1)という)を得た。
次に、前記調製液1B-(2)を陽イオン交換樹脂(三菱化学(株)製、SK1BH)で処理して脱アルカリした。これにより、pHが約9.5の混合水溶液182264g(以下、調製液1C-(2)という)を得た。
フッ化ナトリウム1gを500mLの蒸留水に溶解した。この水溶液を、ビーカー中で、500gの前記調製液1Dに徐々加えて均一な混合物とした。
得られた混合物をステンレス製のバットに移して2〜3cm程度の厚さに薄く広げ、70℃の熱風乾燥機で48時間乾燥させた。重量変化が無くなった時点で乾燥を停止した。得られた白色固体をアルミナ坩堝に移し、550℃に設定した電気炉に投入して、1時間熱処理を行い、49gの白色粉末を得た。この熱処理後の粉末を回転ボールミルにて2時間粉砕し、本発明で用いる複合粉末(A)を得た。該複合粉末の平均粒子径は8.3μm、粒子径範囲は0.5〜75μm、BET比表面積は184m2/g、粉末の屈折率は1.539であった。
またさらに該複合粉末につき、回転対陰極X線回折装置RINT−2400(理学電機社製)を使用し、X線広角回折を測定した。測定条件は、印加電圧40kV、電流100mA、ターゲットCu、X線波長(CuKα1)λ=1.5405Å、検出器走査速度1°/minとして、2θ=5〜80°の範囲で測定を行った。その結果、フッ化ナトリウムの結晶に由来する回折ピーク(2θ=39°,56°,70°)と非晶質SiO2と考えられるハロー(2θ=22°)が検出され、シリカとジルコニアからなるマトリックス中にフッ化ナトリウムの超微結晶が均一に分散していることが確認された。
なお、上述の方法で得られた、該粉末を含む歯科用組成物の硬化物の研磨面のSEM観察では、粉末断面のSEM像において、0.1μm以上の不均一な粒子は観察されなかったことから、該フッ化ナトリウムは0.1μm以下の粒子径で酸化物の被覆上に分散していると考えられた。またさらに、二次電子像の観察から均一に分散するフッ化ナトリウムの粒子径を測定した結果、平均粒子径は0.035μmであった。
還流冷却管をセットした三口フラスコ中に、上述の方法で得られた複合粉末50重量部をトルエン250mLに分散し、ここに、シランカップリング剤として、γ−メタクリロイロキシプロピルトリメトシキシラン(信越化学社製KBM503)5重量部を加えた。該混合物を攪拌しながら、3時間加熱還流を行った。混合物を放冷後、ヌッチェでろ過して表面処理粉末を回収した。粉末を真空乾燥して溶剤を除去した後さらに、温風乾燥機中で90℃で3時間熱処理を行って、表面処理複合粉末を得た。なお、該表面処理複合粉末の強熱残分(550℃)を測定することで、粉末表面と反応して付着したシランカップリング剤の量が判るが、元の複合粉末100重量部に対して5重量部のシランカップリング剤が付着していることがわかった(この表面処理複合粉末をF1という)。
ラジカル重合性単量体として、UDMAを30重量部、D−2.6Eを40重量部、3Gを30重量部、光重合開始剤として、dl−カンファーキノンを0.3重量部とN,N−ジメチルアミノ安息酸エチル0.5重量部を均一に混合溶解して、重合性単量体組成物を調製した。この重合性単量体組成物の重合硬化後の屈折率は1.535であった。
なお、重合性単量体の略称は具体的に以下の化合物を表す。
UDMA:[2,2,4−トリメチルヘキサメチレンビス(2−カルバモイルオキシエチル]ジメタクリレート
D2.6E:2,2−ビス(4−メタクリロイルオキシポリエトキシフェニル)プロパン(エトキシ基の平均付加モル数:2.6)
3G:トリエチレングリコールジメタクリレート
上記の操作で得られた重合性単量体組成物100重量部、表面処理複合粉末(F1)150重量部をガラス製乳鉢で混練して、均一なペースト状組成物を作製し、さらに減圧脱泡を行って本発明の歯科用組成物を得た。
実施例1の複合粉末の製造において、フッ化ナトリウム水溶液を加えない他は、実施例1と同じ方法により、水溶性金属塩を含まない、比較用粉末を作製した。該比較用粉末の平均粒子径は6.2μm、粒子径範囲は0.3〜55μm、BET比表面積は189m2/g、粉末の屈折率は1.550であった。実施例1と同様にして歯科用組成物を調製したところ、曲げ強度は136MPa、透明性は40、フッ素イオン徐放量は0μg/cm2であった。
実施例1の複合粉末の製造において、非晶質粉末(a2)が分散したゾル溶液(調製液1D)の代わりに、日産化学社製シリカゾル(スノーテックスPS−M、シリカ含有量30重量%)167gを用いた他は、実施例1と同じ方法により、シリカとフッ化ナトリウムからなる複合粉末を作製した。該複合粉末の平均粒子径は9.6μm、粒子径範囲は0.2〜56μm、BET比表面積は157m2/g、粉末の屈折率は1.443であった。実施例1と同様にして歯科用組成物を調製したところ、曲げ強度は80MPa、透明性は14、フッ素イオン徐放量は161μg/cm2であった。
実施例1の複合粉末の製造において、フッ化ナトリウム水溶液の代わりに、モノフルオロリン酸ナトリウム5gを含む蒸留水200mLを用いた他は、実施例1と同じ方法により、フルオロリン酸ナトリウムが含まれる複合粉末を作製した。該複合粉末の平均粒子径は4.9μm、粒子径範囲は0.5〜67μm、BET比表面積は190m2/g、粉末の屈折率は1.536であった。
実施例1と同様にして歯科用組成物を調製したところ、曲げ強度は124MPa、透明性は46、フッ素イオン徐放量は190μg/cm2であった。なお、該組成物の硬化物の研磨面の電子顕微鏡観察を行い、二次電子像の観察から、該複合粉末中に均一に分散するモノフルオロリン酸ナトリウムの粒子径を測定した結果、0.2μm以上の粒子は存在せず、平均粒子径は0.023μmであった。
