“…Moreover, Ti and its alloys possess mechanical and chemical properties that make them ideal implant materials [15]. Commercially, pure titanium is classified into four grades by its stoichiometric composition, with grade one having the least (0.18%) and grade four having the most (0.4%); in addition, grade five titanium alloy (Ti-6Al-4V) is also used for commercially available dental implants [16,17]. Due to the presence of minimal quantities of contaminants, mechanical features of resistance increase from grade one to grade five [16,18].…”

“…To obtain rutile at low temperatures, precipitation of crystalline TiO 2 and hydrothermal methods are needed [21]. The biological effects of the morphological characteristics of the implant surfaces have been thoroughly investigated [17,22], while little information concerns the influence of the different polymorphic crystalline phases of TiO 2 on osseointegration. The crystalline phase of TiO 2 can influence bioactivity.…”

The aim of the study was to qualitatively investigate the structure of the surface layer of TiO2 on dental implants made of Ti-6Al-4V subjected to different manufacturing treatments. M (machined), B (Al2O3-blasted), E (HNO3\HF-etched), B + E and A (B + E + anodized) implants and a further group receiving the same treatments as the first group with the addition of a final decontamination with cold plasma were included in the study. Examination was performed using micro-Raman spectroscopy. The surface treatments evaluated did not achieve the formation of crystalline TiO2. The increase in the complexity of surface treatment produced a proportional increase in the thickness of amorphous TiO2 oxide. In the B + E group, the plasma treatment enhanced the amorphous oxide thickness of TiO2. The other surfaces treated by plasma decontamination did not show a difference to the respective untreated ones. The investigated surface treatments did not change the crystalline cage of TiO2 in Ti-6Al-4V implants but affected the thickness of the oxide layer. The biological response could be influenced by different oxide thicknesses. Additional information on superficial TiO2 structural organization can be obtained by micro-Raman evaluation of dental implants. Dental implants with B + E + plasma and A superficial treatments allowed the maximum formation of the amorphous oxide thickness.

“…Surface nanoengineering bypasses the boundaries of the surface chemistry of titanium, while keeping the surface topography motifs developed in years of basic studies and clinical practice (Figure ; Rodriguez y Baena, Rizzo, Manzo, & Lupi, ; Wennerberg & Albrektsson, ). The chemical data reported into this work (EDX, XPS, and ζ potential) display a different picture of the surface chemistry of the nanoengineered basic device of dental implantology.…”

The objectives of this study are to evaluate long‐term wettability of novel surface‐engineered, clinically available dental implants, featuring a surface nanolayer of covalently linked hyaluronan, and to confirm the relationships between wetting properties and surface nanostructure and microstructure. Wettability measurements were performed on clinically available hyaluronan‐coated Grade 4 titanium implants, packaged and sterile, that is, in the “on the shelf” condition, after 1 year from production. Wetting properties were measured by the Wilhelmy plate method. Analysis of the surface structure and chemistry was perfomed by X‐ray photoelectron spectroscopy (XPS), scanning electron microscopy (SEM) and energy‐dispersive X‐ray (EDX) analysis, atomic force microscopy (AFM), and ζ‐potential measurement, either on implants or disks or plates subjected to the same surface‐engineering process. Results show that hydrophilicity and ensuing capillary rise of the hyaluronan‐coated implant surface is unaffected by aging and dry storage. Chemical analysis of the implant surface by XPS and evaluation of the ζ potential indicate that hyaluronan chemistry and not that of titanium dictates interfacial properties. Comparison between XPS versus EDX and SEM versus AFM data confirm that the thickness of the hyaluronan surface layer is within the nanometer range. Data show that nanoengineering of the implant surface by linking of the hydrophilic hyaluronan molecule endows tested titanium implants by permanent wettability, without need of wet storage as presently performed to keep long‐term hydrophilic implant surfaces. From an analytical point of view, the introduction in routine clinical practice of nanoengineered implant surfaces requires upgrading of analytical methods to the nanoscale.

“…While there are many studies evaluating the effects of surface treatments on the morphological and chemical characteristics of titanium implants [23,37], there are few studies in the literature evaluating the presence of crystalline titania on the surface of dental implants [12,38]. Thermal treatment and anodization (anodic oxidation) are recognized as capable of producing a layer of crystalline titania on the surface of CP and TA [25,30,39,40]. Some recent studies have confirmed the presence of anatase on commercially available implants with anodized surface [41,42].…”

The osseointegration of titanium implants is allowed by the TiO2 layer that covers the implants. Titania can exist in amorphous form or in three different crystalline conformations: anatase, rutile and brookite. Few studies have characterized TiO2 covering the surface of dental implants from the crystalline point of view. The aim of the present study was to characterize the evolution of the TiO2 layer following different surface treatments from a crystallographic point of view. Commercially pure titanium and Ti-6Al-4V implants subjected to different surface treatments were analyzed by Raman spectroscopy to evaluate the crystalline conformation of titania. The surface treatments evaluated were: machining, sandblasting, sandblasting and etching and sandblasting, etching and anodization. The anodizing treatment evaluated in this study allowed to obtain anatase on commercially pure titanium implants without altering the morphological characteristics of the surface.
