“…Moreover, it has been demonstrated that modifying surface characteristics, such as topographical configuration and physicochemical properties, can influence the osteoconductivity of zirconia implants in a similar manner as has been reported for titanium implants [8,12,13,14]. Here, zirconia implants with roughened surfaces exhibit enhanced osteoconductive capacity, leading to improved osteogenesis and stronger biomechanical fixation when compared to smooth zirconia surfaces [14,15,16].…”

Objective: Improvements in the bioactivity of zirconia implants for accelerated healing and reduced morbidity have been of continuing interest in the fields of dentistry and orthopedic surgery. The aim of the present study was to examine whether UV treatment increases the osteoconductivity of zirconia-based materials. Materials and Methods: Smooth and rough zirconia-based disks and cylindrical implants were treated with UV light for 15 min and subsequently placed in rat femurs. Surface characterization was performed using scanning electron microscopy (SEM), atomic force microscopy (AFM), X-ray photoelectron spectroscopy (XPS) and contact angle measurements. Results: In vivo histomorphometry revealed that the percentage of bone-implant contact and the amount of bone volume, formed around UV-treated implants, increased by 3–7-fold for smooth surfaces and by 1.4–1.7-fold for rough surfaces compared to non-treated specimens at Weeks 2 and 4 of healing, respectively. A biomechanical test showed that UV treatment accelerated the establishment of bone-zirconia integration and enhanced the strength of the bone-implant interface by two-fold. Additionally, surface characterization of the zirconia disks revealed that UV treatment decreased the amount of surface carbon and converted the hydrophilic status from hydrophobic to superhydrophilic. Conclusions: This study indicates that UV light pretreatment enhances the osteoconductive capacity of zirconia-based materials.

“…Moreover, it was also reported that the deposition of the ZrO 2 film on the UHMWPE is strongly limiting its plastic deformation and creep phenomenon . We also demonstrated a wear decrease of UHMWPE when coupled with ZrO 2 ‐coated titanium component . In the present study, was investigated the surface chemistry of ZrO 2 stabilized with yttria and ZrO 2 –Al 2 O 3 composite thin films deposited by PPD.…”

Ceramic coatings are increasingly used for orthopaedic implants to improve the wear resistance and to enhance the integration into bone tissue, resulting in the long‐term stability of the implant. The innovative pulsed plasma deposition technique was used to deposit at room temperature different thin films with required mechanical parameters and good adhesion to the substrate. In this way, the films of nanostructured hydroxyapatite, magnetic hydroxyapatite, zirconia and zirconia ‐ alumina were produced and investigated by X‐ray diffraction, atomic force microscopy and XPS depth profiling techniques. Obtained results revealed the good stoichiometry, sufficient purity of chemical composition, very high uniformity in depth and thermal stability in ultra‐high vacuum of all investigated coatings.

“…PPD has also been tested for depositing YSZ coatings on metal substrates, such as AISI 316-L, titanium, and titanium alloys, to indirectly protect the UHMWPE inlay from wear by coupling it with a low-friction counterpart [42][43][44][45]. In a series of papers, where a range of deposition parameters was investigated, the authors reported the possibility to reduce the wear rate of UHMWPE by finely tuning of the working gas pressure [42].…”

The "pulsed electron deposition" (PED) technique, in which a solid target material is ablated by a fast, high-energy electron beam, was initially developed two decades ago for the deposition of thin films of metal oxides for photovoltaics, spintronics, memories, and superconductivity, and dielectric polymer layers. Recently, PED has been proposed for use in the biomedical field for the fabrication of hard and soft coatings. The first biomedical application was the deposition of low wear zirconium oxide coatings on the bearing components in total joint replacement. Since then, several works have reported the manufacturing and characterization of coatings of hydroxyapatite, calcium phosphate substituted (CaP), biogenic CaP, bioglass, and antibacterial coatings on both hard (metallic or ceramic) and soft (plastic or elastomeric) substrates. Due to the growing interest in PED, the current maturity of the technology and the low cost compared to other commonly used physical vapor deposition techniques, the purpose of this work was to review the principles of operation, the main applications, and the future perspectives of PED technology in medicine.
