Evaluation of titanium dental implants after early failure of osseointegration by means of X-ray photoelectron spectoscopy, electron microscopy and histological studies
(Scientific Research Publishing, 2010-11)
In this work, we analysed 56 clinically failed and retrieved implants by means of scanning electron microscopy (SEM), X-ray photoelectron spectroscopy (XPS) and histological studies. The surface ...
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 ...
Antibacterial approaches in tissue engineering using metal ions and nanoparticles: from mechanisms to applications
(Elsevier, 2021-12)
Bacterial infection of implanted scaffolds may have fatal consequences and, in combination with the emergence of multidrug bacterial resistance, the development of advanced antibacterial biomaterials ...
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 comparison of three different commercial custom-made titanium meshes produced by SLM for dental applications
(MDPI, 2020)
The use of individualized titanium meshes has been referred to in scientific literature since 2011. There are many advantages to its use, however, the main complications are related to early or late ...
Mechanical characterisation and biomechanical and biological behaviours of Ti-Zr binary-alloy dental implants
(Hindawi, 2017)
The objective of the study is to characterise the mechanical properties of Ti-15Zr binary alloy dental implants and to describe their biomechanical behaviour as well as their osseointegration capacity ...
Direct extrusion of individually encapsulated endothelial and smooth muscle cells mimicking blood vessel structures and vascular native cell alignment
(IOP Science, 2020)
Cardiovascular diseases (CVDs) are considered the principal cause of worldwide death, being atherosclerosis the main etiology. Up to now, the predominant treatment for CVDs has been bypass surgery from ...
Early short-term postoperative mechanical failures of current ceramic-on-ceramic bearing total hip arthroplasties
(MDPI, 2020)
Although ceramic-on-ceramic (CoC) bearings have been shown to produce the smallest amount of wear volume in vitro as well as in vivo studies when used for total hip arthroplasties (THA), concerns about ...
Roughness and wettability effect on histological and mechanical response of self-drilling orthodontic mini-implants
(Springer Nature, 2016)
Self-drilling orthodontic mini-implants can be used as temporary devices for orthodontic treatments. Our main goal was to evaluate surface characteristics, roughness and wettability, of surface modified ...
Comparison of zirconia degradation in dental implants and femoral balls: an X-ray diffraction and nanoindentation study
(Springer Nature, 2021)
Background: New tetragonal zirconia polycrystal dental implants stabilized with yttria (Y-TZP) have appeared in the implantology market in the form of single piece or two-piece zircona implant system. ...
