“…This modification has been shown to increase the bone-to-implant contact. [67][68][69] Furthermore, several producers offer implants with chemically modified surfaces. A chemically altered surface based on the sandblasted and acid-etched Institute Straumann SLA ® surface has been shown to exhibit increased surface free energy and hydrophilicity (SLActive ® ), mainly due to reduced hydrocarbon contamination.…”

Cathodic polarization has been reported to enhance the ability of titanium based implant materials to interact with biomolecules by forming titanium hydride at the outermost surface layer. Although this hydride layer has recently been suggested to allow the immobilization of the broad spectrum antibiotic doxycycline on titanium surfaces, the involvement of hydride in binding the biomolecule onto titanium remains poorly understood. To gain better understanding of the influence this immobilization process has on titanium surfaces, mirror-polished commercially pure titanium surfaces were cathodically polarized in the presence of doxycycline and the modified surfaces were thoroughly characterized using atomic force microscopy, electron microscopy, secondary ion mass spectrometry, and angle-resolved X-ray spectroscopy. We demonstrated that no hydride was created during the polarization process. Doxycycline was found to be attached to an oxide layer that was modified during the electrochemical process. A bacterial assay using bioluminescent Staphylococcus epidermidis Xen43 showed the ability of the coating to reduce bacterial colonization and planktonic bacterial growth.

“…The most evaluated electrolytes are composed of calcium [ 11 , 12 ], sulfuric acid [ 13 ], acid [ 14 ], hydrogen fluoride [ 15 ], sodium hydroxide [ 16 ] and hydrofluoric acid [ 17 , 18 , 19 , 20 ]. The first anodized implant marketed with the most substantial number of cohort studies that aimed to evaluate implants success rates was TiUnite (Nobel Biocare, Zurich, Switzerland), whose surface has a moderately rough crystalline oxide layer with a high content of phosphorus [ 21 ].…”

Microbial Adhesion and Biofilm Formation on Bioactive Surfaces of Ti-35Nb-7Zr-5Ta Alloy Created by Anodization

et al. 2021

This study evaluated the microbial colonization (adhesion and biofilm) on modified surfaces of a titanium alloy, Ti-35Nb-7Zr-5Ta, anodized with Ca and P or F ions, with and without silver deposition. The chemical composition, surface topography, roughness (Ra), and surface free energy were evaluated before and after the surface modifications (anodizing). Adhesion and biofilm formation on saliva-coated discs by primary colonizing species (Streptococcus sanguinis, Streptococcus gordonii, Actinomyces naeslundii) and a periodontal pathogen (Porphyromonasgingivalis) were assessed. The surfaces of titanium alloys were modified after anodizing with volcano-shaped micropores with Ca and P or nanosized with F, both with further silver deposition. There was an increase in the Ra values after micropores formation; CaP surfaces became more hydrophilic than other surfaces, showing the highest polar component. For adhesion, no difference was detected for S. gordonii on all surfaces, and some differences were observed for the other three species. No differences were found for biofilm formation per species on all surfaces. However, S. gordonii biofilm counts on distinct surfaces were lower than S. sanguinis, A. naeslundii, and P. gingivalis on some surfaces. Therefore, anodized Ti-35Nb-7Zr-5Ta affected microbial adhesion and subsequent biofilm, but silver deposition did not hinder the colonization of these microorganisms.

“…Changing the properties of the implant surface belongs to the most common strategies to improve bone tissue integration . Traditionally, this has been achieved by altering the surface micro- and nanoscale topography (e.g., by grit-blasting and acid-etching), by coating the implant surface with calcium phosphates, or by anodizing the surface. − More recent approaches have focused on the immobilization of bioactive molecules, such as extracellular matrix proteins, RGD-containing peptides, growth factors, or antimicrobial agents, onto the implant surface to help evoking the desired implant–tissue interaction. − …”

In the quest for finding new strategies to enhance tissue integration and to reduce the risk of bacterial colonisation around endosseous implants, we report the application of auto-oxidative phenolic coatings made of tannic acid and pyrogallol to titanium surfaces. The functionalised surfaces were screened for their biological performance using cultures of primary human osteoblasts and biofilm-forming bioluminescent staphylococci S. epidermidis Xen43 and S. aureus Xen29. No toxic effect of the coatings on osteoblasts was detected. While tannic acid coatings seemed to induce a delay in osteoblast maturation, they revealed anti-inflammatory potential. Similar effects were observed for pyrogallol coatings deposited for 24 h. Thin pyrogallol coatings deposited for 2 h seemed to promote osteoblast maturation and revealed increased calcium deposition. The effects on osteoblast were found to be related to the release of phenolic compounds from the surfaces. While the phenolic coatings could not inhibit
