Abstract
The invention pertains to a biocompatible composition, suitable for use in soft or hard tissue augmentation, wherein the composition is an aqueous suspension containing a carrier fraction of ceramic particles of less than 15 &mgr;m and an augmentation fraction of ceramic particles of at least 20 &mgr;m. The ceramics typically comprise calcium phosphate. The composition is a may be used in soft tissue repair as well as hard bone replacement. It advantageously avoids the need for foreign body materials which are conventionally applied to stabilize augmentation suspensions.
