Natural Hydroxyapatite-Ti-Dioxide Bone Substitutes

Natural coral and hydroxyapatite as bone substitutes An experimental and clinical study

Supercritical carbon dioxide processed resorbable polymer nanocomposite bone graft substitutes.

The development of synthetic bone graft substitutes is an intense area of research due to the complications associated with the harvest of autogenous bone and concerns about the supply of allogenic bone. Porous resorbable polymers have been used extensively in hard tissue engineering applications, but currently lack load-bearing capacity. Supercritical carbon dioxide (scCO(2)) processing is use...

Comparison of hydroxyapatite and beta tricalcium phosphate as bone substitutes after excision of bone tumors.

Long-term results are reported in 23 patients and short-term results in 30 patients presenting with bone tumors treated by curettage or resection followed by implantation of hydroxyapatite (HA) or highly purified beta-tricalcium phosphate (beta-TCP), respectively. Mean follow-up was 97 and 26 months in cases involving HA implantation and beta-TCP implantation, respectively. Radiographs revealed...

The alteration in mechanical properties of bone graft after the addition of hydroxyapatite bone graft substitutes

The problems of supply, cost, increasing demand and infection risk that are associated with the use of allograft are well known. The addition of bone graft substitutes, such as hydroxyapatite (HA) to allograft has various advantages in terms of extending supply and also providing more reliable mechanical properties. In this way HA can be used for both trauma and elective joint replacement surge...
