Notes:
Wollastonite bioceramics prepared from synthetic and natural precursors were implantedin rats in bone and subcutaneous tissues. The implant sites were excised after 7, 30 and 120 days,fixed, dehydrated, embedded in paraffin wax for serial cutting and examined under transmitted lightmicroscope. It was found a very similar behavior for both wollastonite bioceramics. They werebiocompatible, bioactive and biodegradable when implanted in rat bone. The synthetic ceramic wasmore reabsorbable than the one from natural powder. When implanted in subcutaneous rat tissue,both materials elicited a mild initial inflammatory reaction that practically disappeared after 120days. Both materials were encapsulated with a very thin fibrous capsule and slightly reabsorbed attheir surfaces. None of the materials induced ectopic osteogenesis. According to the results, thestudied materials seem to be able for manufacturing reabsorbable bone implants
