Hydroxyapatite Coating on Silicon Nitride Surfaces Using the Biomimetic Method
Silicon nitride based ceramics are promising candidates for biomedical applications due to their chemical and dimensional stability associated to suitable mechanical strength and relatively high fracture toughness. However, the bioinert characteristics of these ceramics limit their application to situations where the formation of chemical bonds between the material and the tissue are not essent...
متن کاملBiomimetic Hydroxyapatite Deposition on Titanium Oxide Surfaces for Biomedical Application
Titanium is widely used as material for permanent implants in orthopedic and dental applications. It is well known that Ti shows a mechanically stable interface towards bone (osseointegration). The good biological properties are due to the beneficial properties of the native oxide (TiO2) that forms on Ti when exposed to oxygen. The native titanium oxide on Ti is usually amorphous and very thin,...
متن کاملInteraction of the Titanium Nanostructured Surface with Simulated Body Fluid
Titanium behaves inert in the terms of its interaction with living tissue. Titanium implants are not usually rejected by the organism, nevertheless creation of the strong implant-bone bond can be long term and difficult process. Research aimed at applications of metallic biomaterials should be therefore focused on bioactivation of the implant surface, which could lead to faster and easier accep...
متن کاملBiomimetic Hydroxyapatite Coating on Metal Implants
The combination of the high mechanical strength of metals with the osteoconductive properties of calcium phosphates make hydroxyapatite coatings on titanium implants widely used in orthopedic surgery. However, the most popular coating method, plasma spraying, exhibits some important drawbacks: the inability to cover porous implants and to incorporate biologically active agents, delamination, an...
متن کاملHigh Biological performance of Silicon Substituted Nano Hydroxyapatite Synthesized in Simulated Body Fluid at 37°C
In this work, we report high biological performance of silicon substituted nano hydroxyapatite (nHA) prepared by immersion of calcium phosphate and sodium silicate as precursors in Simulated Body Fluid (SBF) solution for 24, 36, 48 and 72 hrs at 37°C. Characterization and chemical analysis of the synthesized powders were performed by Fourier transform, infrared spectroscopy (FT-IR), X-ray powde...
