摘要:
The present invention relates to a composite material exhibiting a low or even negligible volumetric shrinkage upon curing, or even a small expansion (e.g. up to 0.5%), in particular composite materials in the form of dental filling materials. The present invention also relates to a method of controlling volumetric shrinkage of a composite material upon curing, and to a method of reconstructing a tooth. The present invention also relates to ultrasonic curing of dental filling materials. The present invention further relates to a population of zirconia particles and methods for preparing such zirconia particles (e.g. zirconia in the tetragonal phase or zirconia in the cubic phase). The martensitic transformation of the filler ingredients is, e.g., triggered by application of ultrasound or by a chemical trigger.
摘要(中):
本发明涉及在固化时表现出低或甚至可忽略的体积收缩率,或甚至小的膨胀(例如高达0.5%),特别是牙科填充材料形式的复合材料的复合材料。 本发明还涉及一种在固化时控制复合材料的体积收缩的方法以及重建牙齿的方法。 本发明还涉及牙科填充材料的超声波固化。 本发明还涉及氧化锆颗粒群和制备这种氧化锆颗粒(例如立方相中的四方相或氧化锆中的氧化锆)的方法。 填充剂成分的马氏体转变例如通过施加超声波或通过化学触发来触发。
