Titanium and Fluoride Co-substitution in Hydroxyl Apatite
Authors
Abstract:
Titanium and fluoride-containing hydroxyl apatite were synthesized through precipitation method following by a hydrothermal stage at 100oC for 6 hours. XRD analysis of the sample scalcinedat650oC for 1 hour revealed that all samples have pure apatite structure. The existence of Fluoride substitution in apatite structure was confirmed by FTIR(Fourier Transform Infrared Spectroscopy) analysis. Surfaces of the samples were studied by zeta potential measurements. Investigating cell parameter and also FWHM (Full Width at Half Maximum) of phosphate v1 peak in Raman spectra showed some different behaviour in samples with titanium and high fluoride concentration attributed to different position of titanium in these samples. Scanning electron microscopy (SEM) was used for investigating the morphology of samples. The Morphology of particles was not affected by adding titanium and fluoride.

Evaluation of Biopolymers Effect on In vitro Biocompatibility Property of Nano Hydroxyl Apatite Composites
In this work, we report the effect of biopolymers (starch and gelatin) on in vitro biocompatibility property of nano hydroxyapatite (nHAp) composites. Cell culture and MTT assays were performed for in vitro biocompatibility. They show that nHAp can affect the proliferation of cells and the nHAp-starch and nHAP-gelatin biocomposites have no negative effect on the cell morphology, viability and p...

NaClKClTiClx was prepared via using titanium sponge to reduce titanium tetrachloride in a NaClKCl melt under a negative pressure at 1023K. The relationship between titanium valence states and [F]/[Ti] molar ratios was investigated with successive adding potassium fluoride in the pre-prepared NaClKClTiClx. It was found that the average valence of titanium ions tended to be stable around 3.0...

Dental implant failure often occurs due to oral bacterial infection. The aim of this study was to demonstrate that antibiotic efficacy could be enhanced with modified titanium. First, the titanium was modified by anodization and heat-treatment. Then, a biomimetic coating process was completed in two steps. Surface characterization was performed with scanning electron microscopy, energy dispersi...

Titanium and its alloys are currently the mainly used materials to manufacture orthopaedic implants due to their excellent mechanical properties and corrosion resistance. Although these materials are bioinert, the improvement of biological properties (e.g., bone implant contact) can be obtained by the application of a material that mimics the bone extracellular matrix. To this aim, this work de...
