Wear in two cases of ceramic on ceramic total hip arthroplasty after 30 years follow up
(Biomedical Research Network, 2018)
Background: Ceramic-on-ceramic (CoC) bearings have been in use in total hip replacement (THR) for more than 40 years, with excellent long-term survivorship but concerns over the ceramic-on-ceramic ...
Impedimetric antimicrobial peptide-based sensor for the early detection of periodontopathogenic bacteria
(Elsevier, 2016-12-15)
Peri-implantitis, an inflammation caused by biofilm formation, constitutes a major cause of implant failure in dentistry. Thus, the detection of bacteria at the early steps of biofilm growth represents ...
Antimicrobial peptides: powerful biorecognition elements to detect bacteria in biosensing technologies
(MDPI, 2018-07-10)
Bacterial infections represent a serious threat in modern medicine. In particular, biofilm
treatment in clinical settings is challenging, as biofilms are very resistant to conventional antibiotic
therapy ...
Synthesis and deposition of silver nanoparticles on cp Ti by laser ablation in open air for antibacterial effect in dental implants
(Elsevier, 2018-07-30)
Silver nanoparticles have been synthetized and deposited on cp Ti substrates in one-step process by the use of laser ablation in open air. The nanoparticles are produced by ablating Ag foil using two ...
Mimicking bone extracellular matrix: integrin-binding peptidomimetics enhance osteoblast-like cells adhesion, proliferation, and differentiation on titanium
(Elsevier, 2015-04-01)
Interaction between the surface of implants and biological tissues is a key aspect of biomaterials research. Apart from fulfilling the non-toxicity and structural requirements, synthetic materials are ...
A dual molecular biointerface combining RGD and KRSR sequences Improves osteoblastic functions by synergizing integrin and cell-membrane proteoglycan binding
(MDPI, 2019-03-21)
Synergizing integrin and cell-membrane heparan sulfate proteoglycan signaling on biomaterials through peptidic sequences is known to have beneficial effects in the attachment and behavior of osteoblasts; ...
Surface guidance of stem cell behavior: chemically tailored co-presentation of integrin-binding peptides stimulates osteogenic differentiation in vitro and bone formation in vivo
(Elsevier, 2016-10-01)
Surface modification stands out as a versatile technique to create instructive biomaterials that are able to actively direct stem cell fate. Chemical functionalization of titanium has been used in this ...
Comparison between sandblasted acid-etched and oxidized titanium dental implants: in vivo study
(MDPI, 2019-07-03)
The surface modifications of titanium dental implants play important roles in the
enhancement of osseointegration. The objective of the present study was to test two di erent
implant surface treatments ...
Mechanical and microstructural characterization of new nickel-free low modulus beta-type titanium wires during thermomechanical treatments
(Elsevier, 2015-06-11)
NiTi alloy is the only practical shape memory alloy (SMA) in biomedical use because of its excellent mechanical stability and functionality. However, it is estimated that between 4.5% and 28.5% of the ...
Mechanical and physicochemical characterization along with biological interactions of a new Ti25Nb21Hf alloy for bone tissue engineering
(SAGE Publications, 2015-03-23)
Nowadays, one of the main challenges in metal implants for bone substitution is the achievement of an elastic modulus close to that of human cortical bone as well as to provide an adequate interaction ...
