摘要

COMPOSITE MATERIAL, IN PARTICULAR A MATERIAL FOR OBTAINING IN DENTISTRY, ULTRASONIC CURE OF MATERIALS FOR OBTAINING IN DENTISTRY AND A POPULATION OF ZIRCENIA PARTICULES. The present invention relates to a composite material which exhibits low or even negligible volumetric shrinkage after curing, or even slight expansion (e.g. up to 0.5%), in particular composite materials in the form of materials for curing. dental filling. The present invention also relates to a process of controlling the volumetric shrinkage of a curing composite material and a process of reconstructing a tooth. The present invention also relates to ultrasound curing of dental filling materials. The present invention also relates to a zirconia particle population and processes for the preparation of such zirconia particles (e.g. tetragonal phase zirconia or cubic phase zirconia). The martensitic transformation of the loading ingredients is, for example, triggered by the application of ultrasound or a chemical trigger.
