Microcrystalline hydroxyapatite complex
A natural mineral with composition similar to that of the min-
eral in bone.
Hydroxyapatite for therapeutic purposes is prepared from bo-
vine bone and contains, in addition to calcium and phosphate,
trace elements, fluoride and other ions, proteins, and gly-
cosaminoglycans. It is administered by mouth to patients re-
quiring both calcium and phosphorus supplementation.
Hydroxyapatite with tricalcium phosphate has been used in
bone grafts.
Hydroxyapatite derived from marine coral has been used in
the construction of orbital implants for use following surgical
removal of the eye.
Reference to problems associated with the use of coral-de-
rived orbital implants.
A mixture of calcium phosphates with calcium carbonate
could be combined to form a paste which could be injected
into acute fractures; under physiological conditions the paste
hardened within minutes, due to the formation of dahilite. a
carbonated apatite, and held the bones in place as it was pro-
gressively replaced by living bone.
