Biomimetic Apatite Coating as an Alternative to Plasma-sprayed Hydroxyapatite Coating for Promotion of Bone Apposition-the Coating Formation and in Vitro Study
Introduction: The calcium phosphate ceramics, in particular hydroxyapatite ( HA), has shown to be capable of conducting bone formation and forming a chemical bond to bone. Because of this osteoconductivity, HA ceramic has been applied in joint reconstruction in the form of coating on joint implants such as hip stems by plasma spraying technique. Direct bone apposition has been repeatedly demons...
متن کاملEffect of Alkali and Heat Treatment on Biomimetic HA Coating on Ti6Al4V
In this study, time of calcium phosphate formation on Ti6Al4V alloy with or without alkali and heat treatments was investigated. Specimens were soaked in 0, 5, 10 M solutions of NaOH at temperatures of 60 or 80 °C for 24, 72 h. Their surfaces were characterized using scanning electron microscopy and thin film X-ray diffraction. It was found that optimum condition is 72h soaking in 5 M NaOH in 8...
متن کاملPLLA scaffolds with biomimetic apatite coating and biomimetic apatite/collagen composite coating to enhance osteoblast-like cells attachment and activity
Novel scaffolds composed of poly(L-lactic acid) (PLLA) skeleton covered with bonelike apatite or apatite/collagen composite were produced via a combined phase-separation technique and an accelerated biomimetic coating process. Saos-2 osteoblast-like cells were used to evaluate the cellular behaviors on these biomimetic coatings. Cell morphologies on the surfaces of PLLA scaffolds, PLLA scaffold...
متن کاملStrontium-substituted apatite coating grown on Ti6Al4V substrate through biomimetic synthesis.
During the last few years Strontium has been shown to have beneficial effects when incorporated at certain doses in bone by stimulating bone formation. It is believed that its presence locally at the interface between an implant and bone will enhance osteointegration and therefore, ensure the longevity of a joint prosthesis. In this study we explore the possibility of incorporating Sr into nano...
متن کاملPreparation and Characterization of Hydroxyapatite Coating on Ti6Al4V Cylinders by Combination of Alkali-Heat Treatments and Biomimetic Method
Biomimetic method was used to apply hydroxyapatite (HA) coating onto Ti6Al4V cylinders. This process is a physicochemical method in which a substrate is soaked in a solution simulating the physiological conditions, for a period of time enough to form a desirable layer of the calcium phosphate on the substrate. In the present study, specimens were soaked in 5, 10 M solutions of NaOH at temperatu...
