hydroxyapatite

 [hi-drok″se-ap´ah-tīt]
an inorganic constituent of bone matrix and teeth, imparting rigidity to these structures.

hy·drox·y·ap·a·tite

(hī-drok'sē-ap'ă-tīt),
A natural mineral structure that the crystal lattice of bones and teeth (that is, amorphous hydroxyapatite) closely resembles; used in chromatography of nucleic acids; also found in pathologic calcifications (for example, atherosclerotic aortas).
Synonym(s): hydroxylapatite

hydroxyapatite

/hy·droxy·ap·a·tite/ (-ap´ah-tīt) an inorganic calcium-containing constituent of bone matrix and teeth, imparting rigidity to these structures. Synthetic compounds with similar structure are used as calcium supplements and prosthetic aids (see durapatite ).

hydroxyapatite

(hī-drŏk′sē-ăp′ĭ-tīt′)
n.
A whitish apatite mineral, calcium hydroxide phosphate, Ca5(OH)(PO4)3, that is the chief mineral component of bones and teeth and provides strength and rigidity to their structures.

hydroxyapatite

[hīdrok′sē·ap′ətīt]
an inorganic compound composed of calcium, phosphate, and hydroxide, found in the bones and teeth in a crystallized latticelike form that gives these structures rigidity.

hy·drox·y·ap·a·tite

(hī-drok'sē-ap'ă-tīt)
A natural mineral structure resembling the crystal lattice of bones and teeth; used in chromatography of nucleic acids; also found in pathologic calcifications.

hydroxyapatite

1. A principal ingredient in tooth enamel. A paste containing the compound has been used experimentally to seal small enamel cavities without drilling.
2. A calcium and phosphorus supplement used to treat OSTEOPOROSIS, RICKETS, OSTEOMALACIA and to maintain body minerals during breast feeding. A brand name is Ossopan.

Hydroxyapatite

A calcium phosphate complex that is the primary mineral component of bone.

(hī-drok'sē-ap'ă-tīt)
A natural mineral structure that the crystal lattice of bones and teeth closely resembles; used in chromatography of nucleic acids; also found in pathologic calcifications.

hydroxyapatite

(hīdrok´sēap´ətīt),
n a mineral compound of the general formula 3Ca3(PO4)2-Ca(OH)2, which is the principal inorganic component of bone, teeth, and dental calculus. It can also be used as bone graft material.
hydroxyapatite ceramic,
n a synthetic substance composed of calcium and phosphate that is similar to a naturally occurring compound found in bones and teeth; used as the primary fabricating material or coating for dental implants.

hydroxyapatite

the principal inorganic constituent of bone matrix and teeth, imparting rigidity to these structures, and consisting of hydrated calcium phosphate.
