Long-term histological evaluation of hydroxyapatite ceramics in humans

Preparation and characterization of apatite deposited on silk fabric using an alternate soaking process

“…All reagents were purchased from Wako Pure Chemical Industries (Osaka, Japan) and used without further purification. Sintered synthetic hydroxyapatite (APACERAM; Asahi Optical Co., Tokyo, Japan) with a Ca/P ratio of 1.67 26 was used as standard hydroxyapatite. Nylon (nylon-6) fabric, a standard adjacent fabric conforming to Japanese Industrial Standards (JIS) (Dyeing and Finishing), was used as the control for the polypeptide.…”

Synthesis and characterization of monetite and hydroxyapatite whiskers obtained by a hydrothermal method

“…Hydroxyapatite (Ca 10 (PO 4 ) 6 (OH) 2 ; HAp) has been widely applied as a biomaterial for the substitution of human bone tissues because of its excellent biocompatibility and bioactivity, serving as an alternative to natural bone grafts [1,2]. The inorganic part of human bone and tooth has chemical and structural similarities to Ca-deficient hydroxyapatite, whereas the morphology of HAp can be significantly different in biological tissues, such as plate-like HAp crystals in bone and needle-like hexagonal prisms in enamel [3].…”

Synthesis of a novel method of nano hydroxyapatite and its application as a bone implant material

“…Synthetic HAP (CalO(P04MOH)2) is used mainly in hard tissue replacement applications since it is capable of undergoing bonding osteogenesis and is chemically stable in vivo for long periods of time [14], [15]. In order to prepare fine HAP powders, many chemical processing routes have been employed, including hydrothermal reactions, sol-gel synthesis, pyrolysis of aerosols and micro-emulsion [1], biomimetic process [2], and chemical precipitation [3], which is the most used alternative. Desired characteristics of synthesized hydroxyapatite are fine and uniform particle size, in the nanometre range, phase homogeneity and minimized degree of particle agglomeration.…”
