“…CaP coatings for orthopaedic and dental implants were introduced by de Groot and Geesink (41,42). Since then numerous reports have been published about the osteoconductive properties of CaP-coated implants (osteoconduction refers to the ability of a biomaterial to support the growth of bone over its surface).…”

“…Most techniques used to prepare inorganic CaP coatings are performed either at extremely high temperatures or under extremely non-physiological conditions (Table II), which preclude the incorporation of biomolecules (41,52,57,63,70). Investigations have attempted to circumvent this difficulty by adsorbing biological agents onto the surfaces of preformed inorganic layers (168)(169)(170).…”

Organic–Inorganic Surface Modifications for Titanium Implant Surfaces

Abstract. This paper reviews current physicochemical and biochemical coating techniques that are investigated to enhance bone regeneration at the interface of titanium implant materials. By applying coatings onto titanium surfaces that mimic the organic and inorganic components of living bone tissue, a physiological transition between the non-physiological titanium surface and surrounding bone tissue can be established. In this way, the coated titanium implants stimulate bone formation from the implant surface, thereby enhancing early and strong fixation of bone-substituting implants. As such, a continuous transition from bone tissue to implant surface is induced. This review presents an overview of various techniques that can be used to this end, and that are inspired by either inorganic (calcium phosphate) or organic (extracellular matrix components, growth factors, enzymes, etc.) components of natural bone tissue. The combination, however, of both organic and inorganic constituents is expected to result into truly bone-resembling coatings, and as such to a new generation of surface-modified titanium implants with improved functionality and biological efficacy.

“…4,5) Surface modifications for enhancing their biocompatibilities have been extensively investigated using physical, chemical, and electrochemical techniques. [6][7][8][9] Of these techniques, micro-arc oxidation (MAO) has recently attracted considerable interest because newly formed titanium oxide films produced by MAO are highly porous and adhere firmly to titanium. [10][11][12][13] By controlling the composition and concentration of the electrolyte, Ca-and P-containing ceramics such as hydroxyapatite have been incorporated into the surface layer by us 14) and others.…”

Surface Characteristics of Titanium Oxide Films Prepared by Micro-Arc Oxidation: Comparison of Direct Current Electrolysis and Pulse Electrolysis

et al. 2011

Oxide layers formed by micro-arc oxidation (MAO) using direct current electrolysis and pulse electrolysis were characterized by scanning electron microscopy, X-ray diffraction, energy-dispersive X-ray spectroscopy and adhesive strength measurements. Ti oxide films fabricated by pulse electrolysis were found to have a significantly higher adhesive strength than those fabricated by direct current electrolysis. This can be explained by the different interface adhesive strengths between the two Ti oxide layers and the Ti substrate, as revealed by cross-sectional SEM micrographs. In addition, the dependences of the voltage and the current on the electrolysis time were investigated.

“…Calcium phosphate coating, specifically hydroxyapatite (HA) coating, is one surface treatment that most commonly employs a plasma spraying process. 1)3) The problem with plasma spraying is the coating thickness, which is approximately 100¯m or more, so that fractures occur in thick coating layer. In addition, the HA phase is prone to decomposition into more soluble phases due to high temperature during plasma spraying 3) and is not applicable to implants with complex shapes.…”

A self-assembled monolayer (SAM) technique was employed to produce carbonate apatite (CA) coatings onto Ti substrates after sulfonation. The Ti substrates thus treated (S-SAM-Ti) were immersed in metastable calcium phosphate solutions containing carbonate to induce precipitation of carbonate apatite on the surface. The uniformity and homogeneity of the CA layer was partly demonstrated by the XPS crater-edge-line analysis. Both calcium and phosphorus were distributed quite evenly within a layer of approximately 1000 nm.
