Monoclinic Hydroxyapatite

Science, 1973
The existence of a monoclinic phase of hydroxyapatite, Ca 5 (PO 4 ) 3 OH, has been confirmed, by single-crystal structure analysis (weighted "reliability" factor = 3.9 percent on |F| 2 ). The structure has space group P 2

Hydroxyapatite and Hydroxyapatite-Based Ceramics

Inorganic Materials, 2002
Data are summarized on the synthesis of hydroxyapatite (HA) by wet-chemical processes, solid-state reactions, and hydrothermal treatment. The conditions for HA preparation via precipitation from solutions of calcium chloride, dibasic ammonium phosphate, and aqueous ammonia are discussed at length.

HYDROXYAPATITE COATINGS

Orthopedics, 1994
ABSTRACTA series of investigations over the past several years has evaluated a number of implant materials with and without plasma-sprayed hydroxyapatite (HA) coatings for use in load-bearing implant applications. HA-coated implants have exhibited greater interface shear attachment characteristics when compared to uncoated implants; these results have ...

Hydroxyapatite Coatings

Clinical Orthopaedics and Related Research, 1988
Significant interest for orthopedic surgical applications of hydroxyapatite compounds is based on a number of reasons including the elemental chemistry of the primarily calcium and phosphate ion substances, the controllability of the crystalline and physical structures to provide a wide range of in vivo interactions, the existing literature on ...

HYDROXYLAPATITE COATINGS

Annals of the New York Academy of Sciences, 1988
Four coating techniques were evaluated to determine which is most suitable for producing a dense, highly adherent coating onto metallic and ceramic implant materials. Two of the selected coating methods have serious limitations for use in this particular application, and did not meet the specified criteria for satisfactory coating as defined in the ...

Srapping Hydroxyapatite Implants

Ophthalmic Surgery, Lasers and Imaging Retina, 1999
Abstract: Hydroxyapatite (HA) implants currently are most commonly wrapped in fresh unprocessed human donor sclera before implantation to facilitate entry into the orbital space and allow extraocular muscle attachment. Autologous temporalis fascia or autologous fascia lata are alternatives, but prolong surgery time and require a second operative site ...
