“…5(1)). The surface roughness of Ti has been reported to influence the osteoconductivity, 14,17,29) but this tendency was not seen in the region of Ra studied in this work, showing almost constant low R B-I value of 20%. Similar low R B-I values were also obtained for the samples with Ra/mm > 0:3 after anodizing in H 2 SO 4 aqueous solution.…”

The aim of this study was to elucidate the relationship between the surface roughness and osteoconductivity of anodized titanium surfaces. Before anodizing, titanium substrates with different surface roughness were prepared by wet-polishing. These substrates were anodized at various voltages in H 3 PO 4 , H 2 SO 4 , and NaOH aqueous solutions, and their surface roughness was controlled simultaneously at the micron level. Surface roughness of these coatings was expressed with the arithmetical means (Ra). The osteoconductivity of anodized samples was evaluated by in vivo tests. In in vivo tests, samples were implanted in rats' tibia for 14 d. Anatase type TiO 2 films were formed on all of the anodized samples for in vivo tests. It was newly found that TiO 2 film with small Ra value exhibited high osteoconductivity than that with high Ra value, especially when Ra value was <0:3 mm. In addition, the osteoconductivity of anodized samples with Ra/mm > 0:3 was not improved by anodizing, showing the same low osteoconductivity of as-polished samples. These tendencies were observed for all of the TiO 2 films regardless of the type of electrolytes.

Some implant manufactures use Al 2 O 3 instead TiO 2 powder to sandblast the machined dental implant, because Al 2 O 3 powder is commercially more easily available and is cheaper than TiO 2 powder. However, Al 2 O 3 powder usually leaves aluminum oxide contamination on the surface, which is potentially toxic. In this work, we subjected Ti discs previously sandblasted with Al 2 O 3 powder to 5 different acid etchings in order to verify which treatment is able to remove incorporated particles of Al 2 O 3 from the surface. One group of samples were only sandblasted and served as control. The samples were analyzed by electron microscopy (SEM, EDS), scanning probe microscopy, and grazing incidence XRD. The control group showed presence of Al 2 O 3 on the surface. Three acid etchings were efficient in removing the alumina from the tested samples. Almost all the tested samples showed higher roughness parameters values than the control samples. Titanium hydride was found in almost all test groups. Moreover, the results suggest that there is no incorporation of the whole Al 2 O 3 particle into the titanium surface after the collision, conversely a particle fragmentation occurs and what remains on the titanium surface are Al 2 O 3 residues.

“…Microspheres of diameter in the range 10-540 µm are typically accelerated toward the surface to be treated, using a compressed air or nitrogen blow. Most used grid materials include corundum (Al 2 O 3 ) [9,10], silicon carbide (SiC) [11], titania (TiO 2 ) [12], hydroxyapatite (HA) [13], zirconia (ZrO 2 ) [14], silica (SiO 2 ) [15] and aluminum powders [15]. The main effect of sandblasting is to change the morphology of the treated surface, substantially increasing its roughness.…”

Surface Treatments and Functional Coatings for Biocompatibility Improvement and Bacterial Adhesion Reduction in Dental Implantology

et al. 2016

Surface modification of dental implants is a key process in the production of these medical devices, and especially titanium implants used in the dental practice are commonly subjected to surface modification processes before their clinical use. A wide range of treatments, such as sand blasting, acid etching, plasma etching, plasma spray deposition, sputtering deposition and cathodic arc deposition, have been studied over the years in order to improve the performance of dental implants. Improving or accelerating the osseointegration process is usually the main goal of these surface processes, but the improvement of biocompatibility and the prevention of bacterial adhesion are also of considerable importance. In this review, we report on the research of the recent years in the field of surface treatments and coatings deposition for the improvement of dental implants performance, with a main focus on the osseointegration acceleration, the reduction of bacterial adhesion and the improvement of biocompatibility.
