“…Fast and reliable bonding to the bone is desirable for orthopaedic and dental implants. Various attempts have been made to induce bone bonding by techniques such as ion implantation [3][4][5], electrochemical [6][7][8][9][10] and hydrothermal treatment [11][12][13][14][15]. Certain chemical and heat treatments have also been attempted [16][17][18][19][20][21].…”

In order to elucidate the main factor governing the capacity for apatite formation of titanium (Ti), Ti was exposed to HCl or NaOH solutions with different pH values ranging from approximately 0 to 14 and then heat-treated at 6008C. Apatite formed on the metal surface in a simulated body fluid, when Ti was exposed to solutions with a pH less than 1.1 or higher than 13.6, while no apatite formed upon exposure to solutions with an intermediate pH value. The apatite formation on Ti exposed to strongly acidic or alkaline solutions is attributed to the magnitude of the positive or negative surface charge, respectively, while the absence of apatite formation at an intermediate pH is attributed to its neutral surface charge. The positive or negative surface charge was produced by the effect of either the acidic or alkaline ions on Ti, respectively. It is predicted from the present results that the bone bonding of Ti depends upon the pH of the solution to which it is exposed, i.e. Ti forms a bone-like apatite on its surface in the living body and bonds to living bone through the apatite layer upon heat treatment after exposure to a strongly acidic or alkaline solution.

“…Smooth, turned (TU) titanium, nanoporous TiO 2 coated (SG), and anodized Ca 2+ modified (OC) surfaces have all been shown to be suitable not only for osseointegration but also for soft tissue healing [92,219]. Titanium surfaces modified with ion implantation (Ca+, N+, and F+), oxidation (anode oxidation, titanium spraying), ion plating (TiN, alumina), and ion beam mixing (Ag, Sn, Zn, and Pt) with Ar+ were compared to polished titanium.…”

Nanotechnology enables the control and modification of the chemical and topographical characteristics of materials of size less than 100 nm, down to 10 nm. The goal of this review is to discuss the role of titanium substrates as nanoscale surface modification tools for improving various aspects of implantology, including osseointegration and antibacterial properties. Techniques that can impart nanoscale topographical features to endosseous implants are described. Since the advent of nanotechnology, cellular specific functions, such as adhesion, proliferation, and differentiation, have been better understood. By applying these technologies, it is possible to direct cellular responses and improve osseointegration. Conversely, modulating surface features by nanotechnology could have the effect of decreased bacterial colonization.

“…The TiO2 film obtained by electrochemical anodizing incorporates P and Ca ions from the electrolyte, which alters the final properties of titanium oxide (Elias & Meirelles, 2010). Experiments in cell cultures have shown that incorporated calcium ions on the implant surface increase the adhesion of human bone cells to the implant, when compared to unmodified titanium implants and implants with incorporated phosphate ions (Fröjd et al, 2008;Feng et al, 2004;Nayab et al, 2005). Also, the release of alkaline phosphatase from osteoblasts during bone formation has been found to be increased (Feng et al, 2004).…”
