“…The choice of sterilization methods was described in 8 studies, whereas it can affect the biocompatibility of the TiO 2 surface. UV irradiation was chosen in 5 studies [9,10,16,20,21] and appears to be the most appropriate technique since it maintains the bioactivity of the nanostructure [23,24].…”

“…In contrast, some protocols included less F-content: 0.3% [9,16], 0.15% [19], or more 1% [18]. Four studies resulted in the formation of a surface with nanopores (NP) [9,12,14,16] and ten studies resulted in the formation of nanotubes (NT) [8,10,11,15,[17][18][19][20][21]23]. Generally, the studies proposing a "short" anodization protocol with a time less than 30 min and the presence of a low amount of F-resulted in NP features.…”

Electrochemically anodized (EA) surfaces promise enhanced biological properties and may be a solution to ensure a seal between peri-implant soft tissues and dental transmucosal components. However, the interaction between the modified nano-structured surface and the gingival cells needs further investigation. The aim of this systematic review is to analyze the biological response of gingival cells to EA titanium surfaces in in vitro studies with a score-based reliability assessment. A protocol aimed at answering the following focused question was developed: “How does the surface integrity (e.g., topography and chemistry) of EA titanium influence gingival cell response in in vitro studies?”. A search in three computer databases was performed using keywords. A quality assessment of the studies selected was performed using the SciRAP method. A total of 14 articles were selected from the 216 eligible papers. The mean reporting and the mean methodologic quality SciRAP scores were 87.7 ± 7.7/100 and 77.8 ± 7.8/100, respectively. Within the limitation of this review based on in vitro studies, it can be safely speculated that EA surfaces with optimal chemical and morphological characteristics enhance gingival fibroblast response compared to conventional titanium surfaces. When EA is combined with functionalization, it also positively influences gingival epithelial cell behavior.

“…Surface modification technologies can diminish hydrocarbon contamination, increase the content of functional OH groups on the material surface, and endow titanium with superhydrophilicity without altering the surface topography ( Choi et al, 2016 ; Matsumoto et al, 2020 ). Furthermore, treatments, such as UV irradiation and plasma treatment, can directly inactivate bacteria and biofilms on the titanium surface while obtaining superhydrophilicity ( Koban et al, 2011 ; Guo et al, 2021 ), thereby creating a sterile environment for implantation. However, resistance to bacterial adhesion during or after implantation is also an aspect that cannot be ignored.…”

In recent years, the rate of implant failure has been increasing. Microbial infection was the primary cause, and the main stages included bacterial adhesion, biofilm formation, and severe inhibition of implant osseointegration. Various biomaterials and their preparation methods have emerged to produce specific implants with antimicrobial or bactericidal properties to reduce implant infection caused by bacterial adhesion and effectively promote bone and implant integration. In this study, we reviewed the research progress of bone integration promotion and antibacterial action of superhydrophilic surfaces based on titanium alloys. First, the adverse reactions caused by bacterial adhesion to the implant surface, including infection and bone integration deficiency, are briefly introduced. Several commonly used antibacterial methods of titanium alloys are introduced. Secondly, we discuss the antibacterial properties of superhydrophilic surfaces based on ultraviolet photo-functionalization and plasma treatment, in contrast to the antibacterial principle of superhydrophobic surface morphology. Thirdly, the osteogenic effects of superhydrophilic surfaces are described, according to the processes of osseointegration: osteogenic immunity, angiogenesis, and osteogenic related cells. Finally, we discuss the challenges and prospects for the development of this superhydrophilic surface in clinical applications, as well as the prominent strategies and directions for future research.

“…Nanoporous materials are categorized as an important class of nanostructured material that possess unique surface and structural characteristics, including high surface area, tunable pore sizes, tunable pore geometries, as well as surface topographies with porous architectures. These unique characteristics of nanoporous materials underline their applications in various fields, such as ion-exchange [ 1 ], separation [ 2 ], catalysis [ 3 ], sensors [ 4 ], water purification [ 5 ], CO 2 capture and storage [ 6 ], renewable energy [ 7 , 8 ], targeted drug delivery [ 9 ], tissue engineering [ 10 ], and implants [ 11 ]. For example, the presence of highly active low-coordinated atoms (i.e., atoms with lower numbers of bonds such as atoms on surfaces, steps, and kinks) on interconnected curved backbones of nanoporous structures make them suitable for catalytic applications.…”

Functional nanoporous materials are categorized as an important class of nanostructured materials because of their tunable porosity and pore geometry (size, shape, and distribution) and their unique chemical and physical properties as compared with other nanostructures and bulk counterparts. Progress in developing a broad spectrum of nanoporous materials has accelerated their use for extensive applications in catalysis, sensing, separation, and environmental, energy, and biomedical areas. The purpose of this review is to provide recent advances in synthesis strategies for designing ordered or hierarchical nanoporous materials of tunable porosity and complex architectures. Furthermore, we briefly highlight working principles, potential pitfalls, experimental challenges, and limitations associated with nanoporous material fabrication strategies. Finally, we give a forward look at how digitally controlled additive manufacturing may overcome existing obstacles to guide the design and development of next-generation nanoporous materials with predefined properties for industrial manufacturing and applications.
