“…Titanium dioxide has been frequently used in dentistry, and its mechanical properties and antibacterial properties have been improved at the nanometer scale [ [57] , [58] , [59] , [60] ]. The applications of titanium are more focused on planting.…”

“…To seek the optimal surface wetting angle, an experimental team used modern fiber engraving laser method to modify the surface of Ti–6Al–4V dental implants at the micro-nano level as shown in Fig. 2 E, which reduced the adhesion of E. coli without affecting osteogenesis [ 59 ].…”

Microbial resistance to nanotechnologies: An important but understudied consideration using antimicrobial nanotechnologies in orthopaedic implants

“…Among all, laser ablation is accepted as the most cost-effective and versatile method to create patterned implant surfaces. Eghbali et al reported the excellent anti - E. coli performance (>90% inhibition) of a micro-groove patterned Ti–6Al–4V implants fabricated by nano-second laser ablation [ 279 ]. The surface-enabled bactericidal effects were found to scale with the increase of groove distance.…”

Influence of Laser Modification on the Surface Character of Biomaterials: Titanium and Its Alloys—A Review

“…Laser The references state that the laser treatment of titanium surfaces allows for controlling the roughness parameters, R a , R z , and R max , in a wide range [55]. The use of a modern fiber laser engraving method [64] allowed the achievement of a surface with a higher roughness than the Ti6Al4V native material. Meanwhile, comparing the results of the roughness measurements at different laser operating parameters, it was observed that with an increase in the laser operating parameters (e.g., groove distance and frequency), there was a decrease in the value of the roughness and an increase in the value of the wetting angle, which was associated with the determination of the surface of the samples as hydrophobic.…”
