In the previous research experiments, the cow bone-calcium phosphate glass composites had adequate scientific properties to be used as medical objects including, 95% of principal molecules were inorganic hydroxyapatite, no contaminating dangerous heavy metal over standard limits (cadmium, arsenic, mercury, lead), high vertical compressive strength (more than 400 kg/cm2 ), and no adverse reactions inside the laboratory animals. In this research, we made cranialfixator buttons from bovine bone-calcium phosphate glass composites, intended for neurosurgical skull closure, tested in 10 patients and follow up for at least 6 months. The results revealed that our inventions have easily performance, really effectiveness, and entirely non-complications.
