초록
The present application provides dental fillers, and methods of making and using dental fillers that include a treated surface that includes phosphorus and a divalent cation. Dental compositions including such dental fillers can be useful for delivering ions to the oral environment.
대표청구항▼
1. A dental filler comprising a treated surface, wherein the treated surface is amorphous and comprises phosphorus and a divalent cation selected from the group consisting of Mg, Ca, Sr, Ba, Zn, and combinations thereof and further comprises a silane, the dental filler obtained by a method comprisin
1. A dental filler comprising a treated surface, wherein the treated surface is amorphous and comprises phosphorus and a divalent cation selected from the group consisting of Mg, Ca, Sr, Ba, Zn, and combinations thereof and further comprises a silane, the dental filler obtained by a method comprising the steps of: dissolving, dispersing, or suspending a phosphorus precursor and a precursor for the divalent cation in one or more liquids;combining the one or more liquids with the dental filler;removing at least a portion of the one or more liquids to provide the treated surface; and heating the dental filler, andwherein the dental filler comprises nanoparticles, agglomerates of nanoparticles, or combinations thereof. 2. A dental filler comprising a treated surface, wherein the treated surface is amorphous and comprises phosphorus and a divalent cation selected from the group consisting of Mg, Ca, Sr, Ba, Zn, and combinations thereof and further comprises a silane, the dental filler obtained by a method comprising the steps of: dissolving, dispersing, or suspending a phosphorus precursor and a precursor for the divalent cation in one or more liquids;combining the one or more liquids with the dental filler;removing at least a portion of the one or more liquids to provide the treated surface; and heating the dental filler, andwherein the treated surface further comprises a source of fluoride ions, a source of aluminum ions, or an antibacterial agent. 3. A dental composition comprising a dental filler and a hardenable resin, the dental filler comprising a treated surface, wherein the treated surface is amorphous and comprises phosphorus and a divalent cation selected from the group consisting of Mg, Ca, Sr, Ba, Zn, and combinations thereof and further comprises a silane, the dental filler obtained by a method comprising the steps of: dissolving, dispersing, or suspending a phosphorus precursor and a precursor for the divalent cation in one or more liquids;combining the one or more liquids with the dental filler;removing at least a portion of the one or more liquids to provide the treated surface; and heating the dental filler,wherein the hardenable resin comprises acid functionality. 4. The dental composition of claim 3 further comprising an additional filler. 5. A dental composition comprising a dental filler and water, the dental filler comprising a treated surface, wherein the treated surface is amorphous and comprises phosphorus and a divalent cation selected from the group consisting of Mg, Ca, Sr, Ba, Zn, and combinations thereof and further comprises a silane, the dental filler obtained by a method comprising the steps of: dissolving, dispersing, or suspending a phosphorus precursor and a precursor for the divalent cation in one or more liquids;combining the one or more liquids with the dental filler;removing at least a portion of the one or more liquids to provide the treated surface; andheating the dental filler. 6. The dental composition of claim 3 further comprising a water-dispersible, polymeric film former. 7. The dental composition of claim 3, wherein the acid functionality comprises carboxylic acid functionality, phosphoric acid functionality, phosphonic acid functionality, sulfonic acid functionality, or combinations thereof. 8. The dental composition of claim 3, further comprising an initiator system. 9. A method of preparing a dental article comprising: (a) combining: a dental filler and a hardenable resin to form a dental composition, wherein the dental filler comprises a treated surface, wherein the treated surface is amorphous and comprises phosphorus and a divalent cation selected from the group consisting of Mg, Ca, Sr, Ba, Zn, and combinations thereof and further comprises a silane, the dental filler obtained by a method comprising the steps of:dissolving, dispersing, or suspending a phosphorus precursor and a precursor for the divalent cation in one or more liquids;combining the one or more liquids with the dental filler;removing at least a portion of the one or more liquids to provide the treated surface; andheating the dental filler, andwherein the dental filler is porous; and(b) hardening the dental composition to fabricate a dental article selected from the group consisting of crowns, fillings, mill blanks, orthodontic devices, and prostheses. 10. A dental filler comprising a treated surface, wherein the treated surface is amorphous and comprises phosphorus and a divalent cation selected from the group consisting of Mg, Ca, Sr, Ba, Zn, and combinations thereof and further comprises a silane, the dental filler obtained by a method comprising the steps of: dissolving, dispersing, or suspending a phosphorus precursor and a precursor for the divalent cation in one or more liquids;combining the one or more liquids with the dental filler;removing at least a portion of the one or more liquids to provide the treated surface; and heating the dental filler, andwherein the dental filler is an oxide, a fluoride, or an oxyfluoride of an element selected from the group consisting of Groups 2-5 elements, Groups 12-15 elements, Lanthanide elements, and combinations thereof. 11. The dental filler of claim 10, wherein the element is selected from the group consisting of Ca, Sr, Ba, Y, La, Ce, Pr, Nd, Pm, Sm Eu, Gd, Tb, Dy, Ho, Er, Tm Yb, Lu, Ti, Zr, Ta, Zn B, Al, Si, Sn, P, and combinations thereof. 12. The dental filler comprising a treated surface, wherein the treated surface is amorphous and comprises phosphorus and a divalent cation selected from the group consisting of Mg, Ca, Sr, Ba, Zn, and combinations thereof and further comprises a silane, the dental filler obtained by a method comprising the steps of: dissolving, dispersing, or suspending a phosphorus precursor and a precursor for the divalent cation in one or more liquids;combining the one or more liquids with the dental filler;removing at least a portion of the one or more liquids to provide the treated surface; andheating the dental filler, andwherein the dental filler is porous and wherein the dental filler comprises a source of fluoride ions. 13. The dental filler of claim 12, wherein the dental filler comprises a fluoroaluminosilicate glass.
