前記重合性単量体成分(A)中において、重合性単量体(a)、(b)、及び(c)の含有量が、(a)20〜60質量%、(b)20〜60質量%、及び(c)5〜45質量%である歯科用組成物である。
〔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、珪素原子及び酸素原子を含有する酸化物で被覆された充填材(B)を含む混合水溶液を調製する工程。
(5)前記工程(4)で得られた混合水溶液中に含まれる充填材(B)を乾燥する工程。
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、珪素成分の含有量が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。
この熱風乾燥工程から得られる乾燥体は、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ことが望ましい。得られる乾燥体の部分構造は、例えば、図1に示すように、シリカ系微粒子を被覆する酸化物及び近接するシリカ系微粒子を被覆する酸化物が、伸長して互いに連結した構造をとることによって、酸化物の被覆が複数のシリカ系微粒子を被覆している構造を有している。また、得られる乾燥体の全体構造は、例えば、図2に示すように、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ている。

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、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。

製造した充填材の平均粒子径の測定には、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。
