대표청구항▼
1. A hardenable dental composition comprising: (a) an organic chemically polymerizable component comprising an ethylenically unsaturated compound;(b) 0.01 wt-% to 10 wt-% of an oxamide compound organogelator; and(c) a filler material in an amount of 60% or more, wherein the filler comprises nanoscop
1. A hardenable dental composition comprising: (a) an organic chemically polymerizable component comprising an ethylenically unsaturated compound;(b) 0.01 wt-% to 10 wt-% of an oxamide compound organogelator; and(c) a filler material in an amount of 60% or more, wherein the filler comprises nanoscopic particles. 2. The hardenable dental composition of claim 1 wherein the hardenable dental composition further comprises a crystalline material comprising a reactive group. 3. The composition of claim 1 wherein the hardenable dental composition further comprises a crystalline material comprising polyesters, polyethers, polyolefins, polythioethers, polyarylalkylenes, polysilanes, polyamides, polyurethanes, or combinations thereof. 4. The composition of claim 3 wherein the hardenable dental composition comprises a crystalline material comprising saturated, linear, aliphatic polyester polyols containing primary hydroxyl end groups. 5. The hardenable dental composition of claim 1 wherein the nanoscopic particles form aggregated networks. 6. The hardenable dental composition of claim 1 wherein the nanoscopic particles comprise fumed silica. 7. The hardenable dental composition of claim 1 wherein the organogelator is polymerizable. 8. The hardenable dental composition of claim 1 wherein the composition is photopolymerizable. 9. The hardenable dental composition of claim 1 wherein the organogelator is of the general formula: wherein each M is independently hydrogen or a polymerizable group, each X is independently an alkylene group, cycloalkylene group, arylene group, arenylene group, or combinations thereof, and n is 1 to 3. 10. The hardenable dental composition of 9 wherein the organogelator is selected from the group consisting of compounds of the formulas: and mixtures thereof. 11. The hardenable dental composition of claim 1 which is in the form of a hardenable self-supporting structure having a first shape and sufficient malleability to be formed into a second shape at a temperature of 15° C. to 38° C. 12. The hardenable dental composition of claim 11 wherein upon hardening the structure in the second shape, the hardened structure has a flexural strength of at least 25 MPa. 13. A dental product comprising a hardenable dental composition comprising: (a) an organic polymerizable component;(b) 0.01 wt-% to 10 wt-% of an oxamide compound organogelator; and(c) a filler material in an amount of 60% or more, wherein the filler comprises nanoscopic particles. 14. The dental product of claim 13 which is a preformed crown. 15. A method of using a dental product, the method comprising: providing a dental product comprising a hardenable dental composition of claim 13 wherein the hardenable dental composition has a self-supporting structure having a first shape and sufficient malleability to be formed into a second shape at a temperature of 15° C. to 38° C.;placing the dental product on a tooth surface in the mouth of a subject or on a model of a tooth surface;customizing the shape of the dental product in the mouth of a subject or on a model of a tooth surface; andhardening the hardenable dental composition of the dental product. 16. The dental product of claim 13 wherein the hardenable dental composition comprises a crystalline material comprising a reactive group. 17. The dental product of claim 13 wherein the hardenable dental composition comprises a crystalline material comprising polyesters, polyethers, polyolefins, polythioethers, polyarylalkylenes, polysilanes, polyamides, polyurethanes, or combinations thereof. 18. The dental product of claim 17 wherein the hardenable dental composition comprises a crystalline material comprising saturated, linear, aliphatic polyester polyols containing primary hydroxyl end groups. 19. The dental product of claim 13 wherein the nanoscopic particles form aggregated networks. 20. The dental product of claim 13 wherein the nanoscopic particles comprise fumed silica. 21. The dental product of claim 13 wherein the organogelator is polymerizable. 22. The dental product of claim 13 wherein the composition is photopolymerizable. 23. The dental product of claim 13 wherein the composition is chemically polymerizable. 24. The dental product of claim 23 wherein the organic polymerizable component comprises an ethylenically unsaturated compound. 25. The dental product of claim 13 wherein the organogelator is of the general formula: wherein each M is independently hydrogen or a polymerizable group, each X is independently an alkylene group, cycloalkylene group, arylene group, arenylene group, or combinations thereof, and n is 1 to 3. 26. The dental product of claim 25 wherein the organogelator is selected from the group consisting of compounds of the formulas: and mixtures thereof. 27. The dental product of claim 13 which is in the form of a hardenable self-supporting structure having a first shape and sufficient malleability to be formed into a second shape at a temperature of 15° C. to 38° C. 28. The dental product of claim 27 wherein upon hardening the structure in the second shape, the hardened structure has a flexural strength of at least 25 MPa.
