“…It then generates lightweight but powerful alloys for the fabrication of oral implants or frameworks for fixed dental prostheses (FDPs) (21) . The Ti6Al4V alloy, often known as Ti64, is α-β titanium alloy that has good biocompatibility, high strength (16,22) , low density, high fracture toughness, and excellent corrosion resistance (23,24,25). In addition to its outstanding density, strength, corrosion resistance and biocompatibility, the Ti6Al4V alloy is an attractive material for dental applications, such as dental bridges and dental implants (23,26,27) .…”

Background: Titanium alloy (Ti6Al4V) is considered a promising material for prosthetic dental applications due to its superior density, high strength, improved corrosion resistance and superior biocompatibility. Due to the low strength and brittleness of the practicable denture foundation material in heat-cured acrylic resin, improving the strength properties is a crucial issue. The present study aimed to evaluate the influence of Ti6Al4V alloy particles on the tensile strength transverse strength, and the surface hardness of heat-cured PMMA as a base material. Materials and methods: A total of 75 specimens were prepared by combining heat-cured acrylic resin with Ti6Al4V additive particles (0.5, 1, 1.5, and 2 wt. % respectively). Each group was subdivided into three subgroups according to the samples subjected to the test (n = 25), tensile strength; transverse strength; and surface hardness. Results: The result showed a significant difference (P= 0.007) in all tested groups. The results showed that the addition of Ti6Al4V particles to heat-cured material considerably increased the tensile strength, transverse strength, and surface hardness-a compared to the untreated control specimens. Conclusion: It was found that increasing the weight concentration (wt.) of Ti6Al4V particles improved the tensile strength, transverse strength, and surface hardness of heat-cured PMMA specimens.

“…However, they are bioinert and cannot bond with living bone; thus, surface modification is necessary. Surface chemical treatment is a common modification method; acid treatment [3], alkali treatment [4], and anodization [5] are various types of surface chemical treatments. In addition, bioactive ceramic coatings, such as hydroxyapatite [Ca 10 (PO 4 ) 6 (OH) 2 ; denoted HA], can be prepared on the surface of a bioinert material.…”

Titanium and its alloys are extensively applied in artificial tooth roots because of their excellent corrosion resistance, high specific strength, and low elastic modulus. However, because of their biological inertness, their surface needs to be modified to improve the osteointegration of titanium implants. The preparation of biologically active calcium–phosphorus coatings on the surface of an implant is one effective method for enhancing the likelihood of bone integration. In this study, osteoinductive peptides were extracted from oyster shells by using acetic acid. Two peptide-containing hydroxyapatite (HA) composite coatings were then prepared: one coating was prepared by hydrothermally synthesizing an HA coating in the presence of peptides (HA/P/M), and the other coating was prepared by hydrothermally synthesizing HA and then immersing the hydrothermally synthesized HA in a peptide solution (HA/P/S). Characterization results indicated that the composite HA coatings containing oyster shell-based peptides were successfully prepared on the alkali-treated pure titanium surfaces. The HA/P/M and HA/P/S composite coatings were found to exhibit excellent hydrophilicity. Protein adsorption tests confirmed that the HA/P/M and HA/P/S coatings had an approximately 2.3 times higher concentration of adsorbed proteins than the pure HA coating.

“…The surface biofunctionalization of orthopedic implants has received much attention including antibiotic-releasing coatings that have been studied for some time and are shown to reduce infections in vivo [11][12][13]. Such coatings are, however, ineffective against antibiotic-resistant bacteria.…”

Additively manufactured (AM) porous titanium implants may have an increased risk of implant-associated infection (IAI) due to their huge internal surfaces. However, the same surface, when biofunctionalized, can be used to prevent IAI. Here, we used a rat implant infection model to evaluate the biocompatibility and infection prevention performance of AM porous titanium against bioluminescent methicillin-resistant Staphylococcus aureus (MRSA). The specimens were biofunctionalized with Ag nanoparticles (NPs) using plasma electrolytic oxidation (PEO). Infection was initiated using either intramedullary injection in vivo or with in vitro inoculation of the implant prior to implantation. Nontreated (NT) implants were compared with PEO-treated implants with Ag NPs (PT-Ag), without Ag NPs (PT) and infection without an implant. After 7 days, the bacterial load and bone morphological changes were evaluated. When infection was initiated through in vivo injection, the presence of the implant did not enhance the infection, indicating that this technique may not assess the prevention but rather the treatment of IAIs. Following in vitro inoculation, the bacterial load on the implant and in the peri-implant bony tissue was reduced by over 90% for the PT-Ag implants compared to the PT and NT implants. All infected groups had enhanced osteomyelitis scores compared to the noninfected controls.
