    Abstract: Dental composite compositions, restorative compositions, and methods for their use are provided. The compositions can contain (a) from about 1 to about 35 weight percent of a monomer portion containing at least one monomer having a functional group capable of undergoing polymerization; (b) from about 75 to about 95 weight percent of a filler portion, the filler portion containing at least a spherical filler portion having at least one spherical filler particle component; and (c) from about 0.01 to about 10 weight percent of a polymerization catalyst portion containing at least one catalyst capable of assisting in the polymerization of the functional group of the monomer portion and hardening of the composite after application of the composite to a tooth surface or other dental surface. The spherical filler portion is present in an amount sufficient to reduce shrinkage of the composite after polymerization to about 1.8 percent or less. Compositions according to the invention are useful in Class I, II, IV, V, Core build-ups, and other types of dental restorations where maximum strength and polishability are desired. Methods for using such compositions in such restorative procedures are also provided.

    Abstract translation: 提供牙科复合组合物，修复组合物及其使用方法。 组合物可以含有（a）约1至约35重量％的含有至少一个具有能够进行聚合的官能团的单体的单体部分; （b）约75至约95重量％的填料部分，所述填料部分至少包含具有至少一个球形填料颗粒组分的球形填料部分; 和（c）约0.01至约10重量％的含有至少一种催化剂的聚合催化剂部分，所述催化剂部分能够辅助单体部分的官能团的聚合，并且将复合材料施加到齿面上后使复合材料硬化 或其他牙齿表面。 球形填料部分的存在量足以减少聚合后复合材料的收缩率至约1.8％或更低。 根据本发明的组合物可用于需要最大强度和可抛光性的I类，II，IV，V，核心组合和其它类型的牙科修复体。 还提供了在这种修复方法中使用这些组合物的方法。

    Abstract: Polymerizable compositions are described containing colored polymerization indicators which confer a visible color on the unpolymerized compositions. Upon polymerization, the compositions exhibit reduced or eliminated color. The compositions can also change their opacity during polymerization. The compositions provide easy visual differentiation between the unpolymerized compositions and substrates on which the compositions are placed. The compositions are useful in clinical and laboratory applications such as those involving teeth, dental implants, orthodontic materials, artificial teeth and bones.

    Abstract translation: 描述了可聚合组合物，其含有在未聚合组合物上赋予可见颜色的着色聚合指示剂。 聚合时，组合物表现出减少或消除的颜色。 组合物也可以在聚合过程中改变其不透明度。 所述组合物在未聚合的组合物和其上放置组合物的底物之间提供容易的视觉分化。 组合物可用于临床和实验室应用，例如涉及牙齿，牙种植体，正畸材料，人造牙齿和骨骼的那些应用。
