| 发明名称 | Dental curing composition | ||
| 摘要 | The present invention relates to a dental curing composition to restore a lost portion of a tooth generated due to dental caries, tooth fracturing, etc. The dental curing composition has packability suitable for restoring a posterior tooth; has a paste character of avoiding stickiness to a filling instrument; has excellent shaping properties; has very little paste character over time; and has a low polymerization shrinkage property. The dental curing composition comprises: (a) a matrix resin whose viscosity at 25° C. is 10,000 to 17,000 mPa·s, (b) an organic-inorganic composite filler, (c) an inorganic filler, and (d) a polymeric initiator. | ||

| 主权项 | 1. A dental curing composition comprising: (a) a matrix resin having a viscosity at 25° C. of 10,000 to 17,000 mPa·s, and comprising a low viscosity polymerizable monomer having a viscosity at 25° C. equal to or lower than 100 mPa·s, wherein a content of the low viscosity polymerizable monomer is equal to or higher than 0.01% by weight and equal to or lower than 10% by weight relative to 100% by weight of the matrix resin, (b) an organic-inorganic composite filler, (c) an inorganic filler, and (d) a polymeric initiator, wherein the content of the matrix resin (a) in the dental curing composition is from 10 to 25% by weight relative to 100% by weight of the dental curing composition, and the total content of the organic-inorganic composite filler (b) and the inorganic filler (c) is from 75% to 90% by weight relative to 100% by weight of the dental curing composition. | ||
