Summary: The study evaluated the effectiveness of on-site benchtop modification technique for implants at time of placement using DBD plasma treatment to improve implant surface properties and cellular response. The results showed that plasma treatment enhanced the differentiation and activity of MSCs and osteoblasts without modifying surface chemical composition, indicating its potential in altering surface properties for improved integration.

Summary: The study discusses the influence of surface roughness frequencies and parameters on mixed wetting and its transitions. It was found that while all roughness frequencies contribute to net roughness parameters, not all of them affect wettability transitions. Parameters such as Rz and LSm were identified as predictors for spatial roughness frequencies that dictate transitions to different wettings states.

Summary: This study utilized laser ablation method in N-2 atmosphere to prepare TiN structure on Ti target, investigating the effects of different N-2 gas pressures and laser scanning cycles on TiN structure formation. It was concluded that increasing the laser scanning cycle had a greater impact on the quantity and quality of TiN structure compared to changing N-2 gas pressure.

Summary: Plasma electrolytic oxidation (PEO) was used to produce titanium oxide (TiO2) coatings, and the morphology, wettability, phase and chemical compositions were analyzed as a function of processing parameters. The bioactivity of the coating was evaluated through in-vitro experiments. The results showed that PEO treatment can generate porous and superhydrophilic TiO2 coatings, promoting cell adhesion and growth.

Summary: Titanium dental meshes have a wide application in regenerating bone tissue. This study aimed to optimize the roughness of the meshes to prevent bacterial colonization while maintaining a good biological seal. The results showed that sandblasting with alumina particles improved the behavior of the meshes with fibroblasts and reduced bacterial colonies. This treatment could be a promising surface treatment for dental meshes.

Summary: This study examined the use of laser micro-machining to create surface texture patterns on titanium specimens for controlling biofilm formation. The findings suggest that laser textured surfaces could potentially reduce biofilm development on surfaces, providing a non-toxic alternative to traditional chemical antifouling methods.

Summary: In this study, the adhesion strength of semi-clathrate hydrate to different solid surfaces was measured, and it was found that the adhesion strength is negatively correlated with the wettability of the surface. Additionally, low wettability and low surface roughness were found to effectively reduce the critical rate required to remove hydrate deposition, achieving self-removal of hydrates. This study holds significant theoretical implications for designing self-cleaning surfaces for oil and gas pipes.

Summary: The objective of this study was to evaluate the changes in the physical and chemical properties of titanium surfaces contaminated by a Nd:YAG laser with different levels of energy and the regulation of macrophage polarization. The results showed that the Nd:YAG laser increased the hydrophilicity and roughness of the titanium surface after decontamination, inhibiting M1-type macrophage polarization and promoting M2-type macrophage polarization.

Summary: This study investigates the wetting behavior and hydrophobic mechanism of 304 stainless steel surface and Ni-Cu-P coatings, showing that the water contact angle change is associated with surface area and surface roughness. The recovery of water repellency is influenced by a time constant related to micro-scale surface deformation or roughness. The research provides a theoretical basis for time-dependent wetting studies.

Summary: Through meta-analysis, we found that there were no significant differences in bond strength between erbium lasers and acid etching, but the Er,Cr:YAG laser group had lower shear bond strength (SBS) than the acid group. In addition, there were statistical significant differences between the erbium laser groups and the acid etching group in terms of adhesive remnant index (ARI) and ARI score.

Summary: By utilizing Er:YAG-SSP photoacoustic irrigation, biofilm removal rate on titanium surfaces can be significantly increased in non-contact mode without the use of abrasives or chemicals, while also decreasing the number of viable bacteria remaining on the surface.

Summary: The surface topography of titanium dental implants has a great influence on osseointegration. In this study, the osteoblastic behavior and gene expression of cells with different titanium surfaces were investigated and correlated with the physicochemical properties of the surface. The results showed that surface roughness and wettability have a significant impact on osteoblastic activity and gene expression.

Summary: The surface of the commercial CoCr28Mo alloy was textured using a 20W pulsed fiber laser with different beam scan strategies, resulting in a chaotic texture formation. The surface roughness ranged from 1 to 7 μm, while the surface topography significantly affected the wettability. The optimal parameters for the laser engraving process were determined using the Taguchi method.
