“…On the other hand, previous in vivo study showed that the bone osteointegration around single HA coated Vitallium alloy and single HA coated SS were almost similar. Based on the point of clinical success and osteointegration, there was no significant difference was observed [15][16]. Vitallium was originally used in endodontic implants however the biocompatibility was questioned when it was shown to undergo surface corrosion [17].…”

Abstract. Porous tantalum has been used as an orthopedic implant for bone defects as it has a good corrosion resistance and fatigue behaviour properties. However, there are some reports on the rejection of porous Ta after the implantation. Those clinical cases refer to the less bioactivity of metallic-based materials. This study aims to evaluate hydroxyapatite coated and uncoated porous Tantalum in order to improve the biocompatibility of porous tantalum implant and osseointegration. Porous tantalum was used as metallic-base substrate and hydroxyapatite coating has been done using plasma-spraying technique. Scanning Electron Microscopy (SEM) and Field Emission Scanning Electron Microscopy (FESEM) techniques were utilizes to investigate the coating characteristics while Confocal Raman Microscopy to investigate the interface and image. The effect of coating to the corrosion behaviour was assessed by employing potentiodynamic polarization tests in simulated body fluid at 37±1 °C. Based on SEM and FESEM results, the morphologies as well the weight element consists in the uncoated and hydroxyapatite coated porous tantalum were revealed. The results indicated that the decrease in corrosion current density for HA coated porous Ta compared to the uncoated porous Ta. This study concluded that by coating porous tantalum with HA supports to decrease the corrosion rate of pure porous.

“…Implants are usually prepared of metals such as titanium alloys, cobalt alloys and SS 316L (García et al, 2004). The need to diminish costs in public health services has constrained the use of SS as the most economical option for orthopedic implants (Meinert et al, 1998;Fathi et al, 2003), because of its comparative low cost, ease of fabrication, ready availability and reasonable corrosion resistance. However, this material is prone to localized attack in long term use due to the hostile biological effects (Yılmaz et al, 2005).…”

“…[9][10][11][12][13][14][15] The beneficial effect of HA coatings on Ti, such as stronger bonding between the bone and the implant, increases uniform bone ingrowth at the bone-implant interface and decreases the release of metal ions from the implant to the body. [16][17][18] To date, a popular manner by which to coat Ti with HA has been through a high heat process called plasma spray deposition, which significantly increases HA crystal growth into the nonbiologically-inspired micron regime. [19][20][21][22][23][24][25] Here, for the first time, we report a new coating method called molecular plasma deposition (MPD) to produce HA coatings with different crystallinity and particle size on Ti.…”

In order to begin to prepare a novel orthopedic implant that mimics the natural bone environment, the objective of this in vitro study was to synthesize nanocrystalline hydroxyapatite (NHA) and coat it on titanium (Ti) using molecular plasma deposition (MPD). NHA was synthesized through a wet chemical process followed by a hydrothermal treatment. NHA and micron sized hydroxyapatite (MHA) were prepared by processing NHA coatings at 500°C and 900°C, respectively. The coatings were characterized before and after sintering using scanning electron microscopy, atomic force microscopy, and X-ray diffraction. The results revealed that the post-MPD heat treatment of up to 500°C effectively restored the structural and topographical integrity of NHA. In order to determine the in vitro biological responses of the MPD-coated surfaces, the attachment and spreading of osteoblasts (bone-forming cells) on the uncoated, NHA-coated, and MHA-coated anodized Ti were investigated. Most importantly, the NHA-coated substrates supported a larger number of adherent cells than the MHA-coated and uncoated substrates. The morphology of these cells was assessed by scanning electron microscopy and the observed shapes were different for each substrate type. The present results are the first reports using MPD in the framework of hydroxyapatite coatings on Ti to enhance osteoblast responses and encourage further studies on MPD-based hydroxyapatite coatings on Ti for improved orthopedic applications.
