“…It is this natural nanostructure that nanotechnology aims to emulate for dental applications [20,21,22,34,35]. Since titanium appears to be more tied to bone when a thin ceramic layer is grown on its surface, through chemical or thermal treatments, several nanostructured surfaces for calcium ion incorporation have been introduced in the market [21,22,23,24,27,28,29,30,31]. …”

“…The best way to evaluate osseointegration in vivo is to retrieve an osseointegrated implant from the human native bone and to analyze the bone-implant interface histologically and istomorphometrically [14,16,19,21]. Obviously, this type of evaluation can be difficult for ethical reasons, and often temporary, mini-implants that are easier to retrieve are used in these studies [14,16,19,21,32,33].…”

“…More recently, to further enhance and speed up bone healing mechanisms, dental implant companies have introduced new surfaces with a controlled nanophotography (i.e., nanostructured surfaces) [21,22,23,24]. In these implants, very often a controlled nanostructure is superimposed to a micro-rugosity [24].…”

Purpose. The aim of this scanning electron microscope (SEM) study was to investigate the interface between the bone and a novel nanostructured calcium-incorporated dental implant surface in humans. Methods. A dental implant (Anyridge®, Megagen Implant Co., Gyeongbuk, South Korea) with a nanostructured calcium-incorporated surface (Xpeed®, Megagen Implant Co., Gyeongbuk, South Korea), which had been placed a month earlier in a fully healed site of the posterior maxilla (#14) of a 48-year-old female patient, and which had been subjected to immediate functional loading, was removed after a traumatic injury. Despite the violent trauma that caused mobilization of the fixture, its surface appeared to be covered by a firmly attached, intact tissue; therefore, it was subjected to SEM examination. The implant surface of an unused nanostructured calcium-incorporated implant was also observed under SEM, as control. Results. The surface of the unused implant showed a highly-structured texture, carved by irregular, multi-scale hollows reminiscent of a fractal structure. It appeared perfectly clean and devoid of any contamination. The human specimen showed trabecular bone firmly anchored to the implant surface, bridging the screw threads and filling the spaces among them. Conclusions. Within the limits of this human histological report, the sample analyzed showed that the nanostructured calcium-incorporated surface was covered by new bone, one month after placement in the posterior maxilla, under an immediate functional loading protocol.

“…Among other applications, the PEO-layer is often applied on the titanium used in the modification of the bone plate for othopaedic or orthodontic application, part of endoprosthesis or dental implants which are used as long-bearing implants [6]. The porosity and surface roughness can be precisely controlled for these functionalizations by regulating electrochemical parameters during the PEO process [7,8].…”

Abstract:The surface modification of titanium alloys is an effective method to improve their biocompatibility and tailor the material to the desired profile of implant functionality. In this work, technologically-advanced titanium alloys-Ti-15Mo, Ti-13Nb-13Zr and Ti-6Al-7Nb-were anodized in suspensions, followed by treatment in alkali solutions, with wollastonite deposition from the powder phase suspended in solution. The anodized samples were immersed in NaOH or KOH solution with various concentrations with a different set of temperatures and exposure times. Based on their morphologies (observed by scanning electron microscope), the selected samples were investigated by Raman and X-ray photoelectron spectroscopy (XPS). Titaniate compounds were formed on the previously anodized titanium surfaces. The surface wettability significantly decreased, mainly on the modified Ti-15Mo alloy surface. Titanium alloy compounds had an influence on the results of the titanium alloys' surface modification, which caused the surfaces to exhibit differential physical properties. In this paper, we present the influence of the anodization procedure on alkali treatment effects and the properties of obtained hybrid coatings.
