✦ Synopsis

A hydroxyapatite [(HAP) Ca 10 (PO 4 ) 6 (OH) 2 ] putty 0.5% sodium alginate in its liquid phase, or FSCPC that is that behaves like a putty or self-curing resin was made by free from sodium alginate. The elements constituting set HAP increasing the amount of sodium alginate in non-decay type putty were examined using powder X-ray diffraction and fast-setting calcium phosphate cement (nd-FSCPC). nd-found to be predominantly apatitic minerals after 24 h. Since FSCPC became viscous as the sodium alginate concentration the handling properties of a putty or self-curing resinlike was increased. The best handling properties were obtained cement are very useful in certain surgical procedures, HAP when nd-FSCPC contained 8% sodium alginate in its liquid putty made by increasing the sodium alginate concentration phase. When a 2-kg glass plate was placed on the paste, HAP in nd-FSCPC is potentially a valuable new biomaterial for putty spread to form an area three times that of FSCPC paste.

use in plastic and reconstructive surgery, as well as oral and Thus, HAP putty is expected to be easier to use than FSCPC maxillofacial surgery.
