Definitions
- the present invention relates to a photocurable composition, and more particularly to a photocurable composition used as a dental filling / restoration material for repairing a deep cavity formed in a posterior tooth (Posterior tooth).
- the photocurable composition has been rapidly spread as a dental filling restorative material in recent years because it can impart the same color tone as natural teeth and is easy to treat, and is now applied to most of the treatment of front teeth. Yes. Moreover, the thing excellent in mechanical strength which can be used also for the restoration of the molar part to which a high bite pressure is applied has been developed.
- a photocurable composition obtained by blending a polymerizable monomer with a large amount of an inorganic filler and a photopolymerization initiator is advantageously used.
- a filling restorative material photo-curable composition
- a special light irradiator to activate the active light
- the polymer is cured by irradiation, and the teeth are restored by the formed cured polymer.
- a photocurable dental filling and restorative material is built up in the shape of a tooth to be repaired on a plaster model, this is polymerized and cured by light irradiation, and then the obtained dental It is also practiced to repair a tooth by adhering a hardened body of a filling restorative material to a tooth with a dental cement.
- visible light is used for the photocuring from the viewpoint of safety to the human body, and therefore a visible light polymerization initiator is usually used as the photopolymerization initiator.
- a system in which the number of processing steps on the tooth surface is simplified is one example.
- a photocurable composition that becomes a composite resin is usually 1 to 2 mm.
- a technique is adopted in which an operation of applying to the cavity with a certain thickness and performing polymerization and curing by light irradiation is repeated.
- the method of filling a photocavity composition into a large cavity at once and polymerizing by light irradiation is likely to cause peeling at the bottom or margin due to polymerization shrinkage or polymerization failure, and prognosis such as margin coloring or secondary caries. This is because there is a risk of causing defects.
- the method of applying the photocurable composition into the cavity little by little, and performing polymerization curing each time, and laminating it is not only troublesome, but also the first polymerized layer and the next polymerized layer. There is a risk that air bubbles may be caught in the interface. When such bubble entrapment occurs, not only the life of the polymerized cured body (composite resin) is reduced, but also secondary caries are likely to occur.
- Patent Documents 1 to 4 propose photocurable compositions with reduced polymerization shrinkage (shrinkage rate and shrinkage stress).

で示される条件(X2)を満足するように選択することが好ましい。
(i)無機充填材成分(B)の屈折率nF、及び有機無機複合充填材成分(C)中の無機充填材成分(C1)の屈折率nPF、有機重合体成分(C2)の屈折率nPPが、重合性単量体成分(A)の屈折率nMに極めて近い領域とする(前記式(1a-a~1a-c))。

(iii)無機充填材成分(B)の屈折率nFが有機無機複合充填材(C)中の有機重合体成分(C2)の屈折率nPP、及び有機無機複合充填材(C)中の無機充填材成分(C1)の屈折率nPFが無機充填材成分(B)の屈折率nFに極めて近い領域とする(前記式(1c-a~1c-b))。
-0.015<nM-nPF<0.015 (1a-b’)
-0.015<nM-nPP<0.015 (1a-c’)
このことから理解されるように、式(1a-a’)は、用いる無機充填材成分(B)の屈折率nFが、重合性単量体成分(A)の屈折率nMに極めて近い範囲内にあること;式(1a-b’)は、有機無機複合充填材成分(C)中の無機充填材成分(C1)の屈折率nPFが、重合性単量体成分(A)の屈折率nMに極めて近い範囲内にあること;及び式(1a-c’)は、有機無機複合充填材成分(C)中の有機重合体成分(C2)の屈折率nPPが、重合性単量体成分(A)の屈折率nMに極めて近い範囲内にあることを示している。このため、このような重合性単量体成分(A)、無機充填材成分(B)及び有機無機複合充填材成分(C)を含む光硬化性組成物では、重合性単量体成分(A)と無機充填材成分(B)との界面、重合性単量体成分(A)と有機無機複合充填材成分(C)中の無機充填材成分(C1)との界面、及び重合性単量体成分(A)と有機無機複合充填材成分(C)中の有機重合体成分(C2)との界面での光の拡散反射や散乱が極めて小さくなり、その結果、光の透過性が大きく、大きな硬化深度を実現できる。

0.005<|nP-nPP|<0.050 (1b-c’)
0.005<|nPP-nPF|<0.030 (1b-d’)
このことから理解されるように、式(1b-a~1b-d)は、用いる無機充填材成分(B)の屈折率nFと重合性単量体成分(A)の重合体の屈折率nP、有機無機複合充填材成分(C)中の無機充填材成分(C1)の屈折率nPFと重合性単量体成分(A)の重合体の屈折率nP、有機無機複合充填材成分(C)中の有機重合体成分(C2)の屈折率nPPと重合性単量体成分(A)の重合体の屈折率nP、有機無機複合充填材成分(C)中の無機充填材成分(C1)の屈折率nPFと有機重合体成分(C2)の屈折率nPPが適度に離れた領域にあることを示している。即ち、重合性単量体成分(A)から得られる重合体自体は、先にも述べたように光透過性の高いものであるが、かかる重合体の屈折率nPと無機充填材成分(B)の屈折率nF、有機無機複合充填材成分(C)中の無機充填材成分(C1)の屈折率nPF及び有機重合体成分(C2)の屈折率nPPとが適度に離れている。そのため、この光硬化性組成物から得られる硬化体では、重合性単量体成分(A)の重合体と無機充填材成分(B)との両者の界面、重合性単量体成分(A)の重合体と有機無機充填材成分(C)中の無機充填材成分(C1)との両者の界面、及び重合性単量体成分(A)の重合体と有機無機充填材成分(C)中の有機重合体成分(C2)との両者の界面それぞれでの拡散反射や散乱の程度が大きくなる。また、有機無機複合充填材成分(C)中の無機充填材成分(C1)の屈折率nPFと有機重合体成分(C2)の屈折率nPPは、重合性単量体成分(A)の重合前後(光硬化性組成物の硬化前後)で変化が無いため、光硬化性組成物の硬化前の十分な透明性と光硬化性組成物の硬化後の有機無機複合充填材成分(C)中の無機充填材成分(C1)と有機重合体成分(C2)との界面での拡散反射や散乱の程度との両立ができる差である必要があり、式(1b-d)の関係を満たすように有機無機複合充填材成分(C)中の無機充填材成分(C1)と有機重合体成分(C2)が選択される。この結果、硬化前の光硬化性組成物は透明性を有しているが、光硬化性組成物の硬化体は半透明で光拡散性を有し、その外観が天然歯牙と調和するようになる。
D=(((I(20)/cos20°)+(I(70)/cos70°))/(2×I(0)))×100
-0.020<nF-nPP<0.020 (1c-b’)
このことから理解されるように、式(1c)は、無機充填材成分(B)の屈折率nFと有機無機複合充填材成分(C)中の無機充填材成分(C1)の屈折率nPFとの差、無機充填材成分(B)の屈折率nFと有機無機複合充填材成分(C)中の有機重合体成分(C2)の屈折率nPPとの差が非常に近い領域にあることを示している。これらの屈折率差が過度に大きいと上記式(1a-a~1a-c)を満たしていたとしても硬化されていない硬化性組成物が不透明となってしまい、硬化深度が小さくなってしまうことがある。上記式(1c-a~1c-b)を満たしていれば、このような不都合を確実に回避できる。

上述した重合性単量体を、表1に示す質量比で混合し、実施例および比較例で使用する重合性単量体成分(A)としてM-1~M-10を調製した。

コントラスト比=背景色黒の場合のYb値/背景色白の場合のYw値
厚さ0.5mm板の中央部に直径30mmの貫通孔を形成した型枠に、光硬化性組成物を充填した。十分に光重合を行って光硬化性組成物を硬化させることにより、硬化体を得た。硬化体を型枠から取り出し、37゜Cの水中に24時間浸漬して、試験片を得た。この試料片について、ゴニオフォトメーター(村上色彩技術研究所、GP-2000)を用いて、透過光の光度分布を測定した。光拡散度Dは以下の式に従って計算した。
D=[{(I(20)/cos20゜)+(I(70)/cos70゜)}/(2×I(0))]×100
但し、上記式中のI(0)、I(20)、及びI(70)は、上記厚さ0.5mmの板状試験片の表面に対して垂直に光を照射した場合において、光の入射方向に対してそれぞれ、0゜、20゜、及び70゜の方向に透過した光強度を意味する。

走査電子顕微鏡(XL-30S FEG フィリップス社製)を用い、無機充填材及び有機無機複合充填材の写真を5000~100000倍の倍率で撮影した。画像解析ソフト(IP-1000PC 旭化成エンジニアリング社製)を用いて、撮影した画像の処理を行い、単位視野内における一次粒子の円相当径(粒子径)、最大長、最小幅と粒子数を求め、平均一次粒子径を算出した。観察対象の粒子数は100個以上とした。
水銀ポロシメーター(商品名;「ポアマスター」(PoreMaster)、クワンタクローマ(Quantachroma)社製)を用いた。0.2gの有機無機複合充填材を測定セルに入れて、細孔容積分布を測定した。細孔容積分布孔径1~500nmの範囲の容積を積算し、細孔容積とした。
充填器を用いて、歯科用硬化性組成物のペーストをステンレス製型枠(厚さ2mm、幅2mm、長さ25mm)に充填した。充填したペースト表面にポリプロピレンシートを圧接し、ポリプロピレンシートを通してペーストに光照射を行なった。光照射は、可視光線照射器「パワーライト」(商品名;トクヤマ社製)を用いた。可視光照射器の照射窓をポリプロピレンシートに密着させ、硬化体の全体に光が照射されるように、場所を変えて一方の面から各30秒間ずつ3回光照射した。次いで、反対の面からも同様にして各30秒間ずつ3回光照射した。この操作により、ペーストは重合し、硬化体が得られた。
#800の耐水研磨紙を用いて、硬化体を2×2×25mmの角柱状に整えた。この試料片を試験機(島津製作所製、商品名「オートグラフAG5000D」)に装着し、支点間距離20mm、クロスヘッドスピード1mm/分の試験条件で、3点曲げ破壊強度を測定した。試験片5個について評価し、その平均値を曲げ強さとした。
試験機(島津製作所製、商品名「オートグラフAG5000D」)に接続した治具において、直径6mmのロッド上面にワンナップボンドFプラスを塗布して光照射後、リングを被せ、深さ4mmの模擬窩洞とした。この模擬窩洞にコンポジットレジンを充填し、可視光線照射器「パワーライト」(商品名;トクヤマ社製)を用いて、可視光を所定の時間照射した。この時、重合収縮によりロードセルを固定しているクロスヘッドが下方に移動しようとするが、その微小移動を変位検出器にて検出し、クロスヘッドが移動しないよう自動制御した。この時に、ロードセルによって検出される力を収縮応力とした。

実施例5及び実施例8で得られた光硬化性組成物のペーストに対して、表10に示した着色剤を加えて、暗所にて十分に混練した。着色したペーストを減圧下脱泡して気泡を除去し、着色剤を含む光硬化性組成物を得た。加えた着色剤のうち、白色顔料の二酸化チタンは無機充填材として見なされるが、実施例15~18、参考例1,2においては最大でも200.0ppm(0.02%)しか含まない。実施例5及び実施例8は100%の無機充填材が条件(X1)を満たしているため、加えられた着色剤を考慮しても実施例15~18、参考例1,2の無機充填材のうち90%以上は条件(X1)を満たす。
