“…Ionescu et al reported an inhibitory effect of femtosecond laser treated titanium surface on bacterial biofilm development [30]. Doll et al demonstrated the effect of different topographies created by nanosecond laser ablation on the development of S. oralis biofilm, where some structures had an inhibitory effect while others did not [31]. The antibacterial effect of femtosecond laser modified titanium surface was also reported by other authors [32].…”

Titanium and its alloys are commonly used in modern implantology. Cell viability on the surface of titanium implants depends on the surface topography, roughness, and wettability. Laser treatment is a successful method to control the surface morphology.The aim of this study was to comprehensively investigate the effects of laser ablation on titanium surfaces and their interactions with cells and bacteria. Cell adhesion, proliferation, and bacterial retention on smooth and laser-textured samples of commercially pure and nanostructured titanium of two grades were evaluated. Femtosecond laser treatment effectively enhances the wettability. Titanium grade four exhibits superior adhesion and proliferation rates when compared to titanium grade two. The cytotoxicity of nanostructured titanium is significantly lower, regardless of the surface treatment. Laser treatment resulted in increased short-term cell proliferation on grade two titanium and long-term cell proliferation on nanostructured grade two titanium only. Although the laser ablation has a limited effect on bacterial adhesion, the coverage of less than 1% in most samples indicates that the material itself has an antibacterial effect on the bacterial strain S. oralis.These findings provide valuable insights into how different material structures and surface treatments can affect cellular response and antibacterial properties for potential use in dental implantology.

“…In our previous work (Doll et al 2021), the antibacterial effect of laser-induced oxide coatings of titanium oxide was demonstrated when they were irradiated at a wavelength 375 nm. Depending on the composition of the oxide lm, its thickness, wavelength of radiation and duration of exposure it is possible to control the intensity and duration of the antibacterial effect.…”

In modern dentistry dental implants are widely used to replace lost teeth. However, the placement of an implant may not be possible due to bone atrophy. One of the most modern ways to restore jawbone after atrophy is the use of barrier membranes. This paper proposes a method to design and create an improved barrier membranes using neural networks and laser technology. This development allows to obtain a personalized titanium membrane with a laser-induced antibacterial coating. At the first step the membrane is designed based on CT scan of the patient using 3D modeling software and convolutional neural network U-net, which allows us to reduce modeling time. The second step is to create membrane by micromilling from a titanium block. Finally, at the third step we create antibacterial membrane surface under laser oxidation and UV-activation of singlet oxygen production on the surface.

Bacterial biofilms pose serious problems in medical and industrial settings. One of the major societal challenges lies in the increasing resistance of bacteria against biocides used in antimicrobial treatments, e.g., via overabundant use in medicine, industry, and agriculture or cleaning and disinfection in private households. Hence, new efficient bacteria‐repellent strategies avoiding the use of biocides are strongly desired. One promising route to achieve bacteria‐repellent surfaces lies in the contactless and aseptic large‐area laser‐processing of technical surfaces. Tailored surface textures, enabled by different laser‐processing strategies that result in topographic scales ranging from nanometers to micrometers may provide a solution to this challenge. This article presents a current state‐of‐the‐art review of laser‐surface subtractive texturing approaches for controlling the biofilm formation for different bacterial strains and in different environments. Based on specific properties of bacteria and laser‐processed surfaces, the challenges of anti‐microbial surface designs are discussed, and future directions will be outlined.
