For millennia the unique physical and chemical properties of glasses have made them one of mankind's most useful discoveries. 33 years ago silicate-based glasses were discovered to have unique biological properties. special compositions of Si02-Ca0-Na20-P205 glasses were found to bond to living bone. These glasses, called bioactive glasses and trademarked as 45S5 Bioglass, are now used worldwide for the repair of bone defects.
