“…The type of titanium used is another important factor that must be added to the variables of surface characterization, as it directly influences the roughness of the implant due to different hardness of titanium according to its class [32]. In our implants, the titanium used was grade IV.…”

(1) Background. Titanium is characterized by its biocompatibility, resistance to maximum stress, and fatigue and non-toxicity. The composition, surface structure, and roughness of titanium have a key and direct influence on the osseointegration processes when it is used in the form of dental implants. The objective of the present study is to characterize, at chemical, superficial, and biological levels, the result of the application of the sandblasted with large-grit and acid-etched (SLA) treatment consisting of coarse-grained and double-passivated acid blasting with subsequent decontamination with argon plasma on the surface of titanium implants type IV. (2) Methods. Four Oxtein® dental implants (Zaragoza, Spain) were investigated with the following coding: Code L63713T (titanium grade IV, 3.75 mm in diameter, and 13 mm in length). The surface of the implants was SLA type obtained from coarse-grained, double passivated acid, and decontaminated with argon plasma. The samples were in their sealed packages and were opened in our laboratory. The X-ray photoelectron spectroscopy (XPS) technique was used to characterize the chemical composition of the surface, and the scanning electronic microscope (SEM) technique was used to perform topographic surface evaluation. Cell cultures were also performed on both surfaces. (3) Results. The superficial chemical analysis of the studied samples presented the following components, approximately, expressed in atomic percentage: O: 39%; Ti: 18%; C: 39%; N: 2%; and Si: 1%. In the same way, the topographic analysis values were obtained in the evaluated roughness parameters: Ra: 1.5 μm ± 0.02%; Rq: 1.31 μm ± 0.33; Rz: 8.98 μm ± 0.73; Rp: 5.12 μm ± 0.48; Rv: 3.76 μm ± 0.51; and Rc: 4.92 μm ± 0.24. At a biological level, the expression of osteocalcin was higher (p < 0.05) on the micro-rough surface compared to that machined at 48 and 96 h of culture. (4) Conclusions. The data obtained in our study indicate that the total carbon content, the relative concentration of titanium, and the roughness of the treatment performed on the implants are in agreement with those found in the literature. Further, the roughness of the treatment performed on the implants throws a spongy, three-dimensional surface suitable for bone growth on it. The biological results found are compatible with the clinical use of the surface tested.

“…Moreover, implants classified as having roughened surfaces had a statistically significantly lower probability to fail in comparison with turned implants, in both bruxers and non-bruxers. It has been shown that the osseointegration process is influenced by several factors (Chrcanovic et al 2014), among them the surface texture (Albrektsson & Wennerberg 2004;Chrcanovic et al 2015b). There is supportive evidence for a positive relationship between an improved bone healing around implants and its surface roughness (Shalabi et al 2006), which enhances the process of osseointegration.…”

“…As the implant surface is the first component to interact with the host, several surface modifications have been extensively investigated in the search for improved bone healing . Alterations in surface texture and chemistry are modifications used commonly to increase the biological response to implants . Anodic oxidation, an electrochemical process that increases the TiO2 surface layer and roughness, is one of the methods currently used to modify the surface of a dental implant.…”

Summary The aim of this meta‐analysis was to test the null hypothesis of no difference in the implant failure rates, marginal bone loss (MBL)and post‐operative infection for patients being rehabilitated by turned versus anodised‐surface implants, against the alternative hypothesis of a difference. An electronic search without time or language restrictions was undertaken in November 2015. Eligibility criteria included clinical human studies, either randomised or not. Thirty‐eight publications were included. The results suggest a risk ratio of 2·82 (95% CI 1·95–4·06, P < 0·00001) for failure of turned implants, when compared to anodised‐surface implants. Sensitivity analyses showed similar results when only the studies inserting implants in maxillae or mandibles were pooled. There were no statistically significant effects of turned implants on the MBL (mean difference‐MD 0·02, 95%CI −0·16–0·20; P = 0·82) in comparison to anodised implants. The results of a meta‐regression considering the follow‐up period as a covariate suggested an increase of the MD with the increase in the follow‐up time (MD increase 0·012 mm year−1), however, without a statistical significance (P = 0·813). Due to lack of satisfactory information, meta‐analysis for the outcome ‘post‐operative infection’ was not performed. The results have to be interpreted with caution due to the presence of several confounding factors in the included studies.
