Tooth loss is common in patients struggling with dental cavities, periodontal diseases, and tumors, as well as those
who abuse tobacco or drugs. In this scenario, dental implants have become the primary treatment option for
complete or partial tooth loss. Dental implant failure can be caused by stress shielding phenomenon, poor
osseointegration, or to bacterial infections. In the present study, a joint solution to these limitations is proposed
using a variety of porous β-titanium substrates using powder Ti35Nb7Zr5Ta alloy and employing the spacer-holder
approach (ammonium bicarbonate) to obtain a variety of porosity percentage (30, 40, and 50 vol%), and pore
diameters in 100–200 μm, that has been characterized in terms of its size distribution, density, morphology,
chemical composition, compaction ability and Vickers micro-hardness. Furthermore, porosity, microstructure
(Archimedes and image analysis) and tribomechanical behavior (P-h curves and scratch tests) experiments were
performed to study and characterize the porous substrates. Polyvinyl alcohol (PVA)/poly-ε-caprolactone (PCL)
containing silver nanoparticles (AgNPs), as antibacterial composite, was employed to infiltrate β-Ti disks. Scanning
electron microscopy was used to determine the coating morphology, thickness, and infiltration of the porous
substrates. Wettability and SBF experiments were also carried out to investigate hydrophobicity and potential biofunctionality.
The results suggested how the porosity of the β-Ti alloy affects the mechanical characteristics and the
wettability of the substrate that was successfully infiltrated to exert an antimicrobial behavior
