Two different strategies to enhance osseointegration in porous titanium: inorganic thermo-chemical treatment versus organic coating by peptide adsorption
(MDPI, 2018)
In this study, highly-interconnected porous titanium implants were produced by powder sintering with different porous diameters and open interconnectivity. The actual foams were produced using high cost ...
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 ...
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; ...
Antibacterial properties of hLf1-11 peptide onto titanium surfaces: a comparison study between silanization and surface initiated polymerization
(ACS Publications, 2015)
Dental implant failure can be associated with infections that develop into peri-implantitis. In order to reduce biofilm formation, several strategies focusing on the use of antimicrobial peptides (AMPs) ...
All-in-one trifunctional strategy: a cell adhesive, bacteriostatic and bactericidal coating for titanium implants
(Elsevier, 2018-09)
Strategies to inhibit initial bacterial adhesion are extremely important to prevent infection on biomaterial surfaces. However, the simultaneous attraction of desired eukaryotic cells remains a challenge ...
Antifouling coatings for dental implants: PEG-like coatings on titanium by plasma polymerization
(American Vacuum Society, 2015-06)
Titanium dental implants are commonly used for the replacement of lost teeth, but they present a considerable number of failures due to the infection on surrounding tissues. The aim of this paper is the ...
Silver deposition on titanium surface by electrochemical anodizing process reduces bacterial adhesion of Streptococcus sanguinis and Lactobacillus salivarius
(Wiley, 2014-05-30)
Objectives: The aim of this study was to determine the antibacterial properties of silver‐doped titanium surfaces prepared with a novel electrochemical anodizing process. Material and methods: Titanium ...
Anhydride-functional silane immobilized onto titanium surfaces induces osteoblast cell differentiation and reduces bacterial adhesion and biofilm formation
(Elsevier, 2016)
Bacterial infection in dental implants along with osseointegration failure usually leads to loss of the device. Bioactive molecules with antibacterial properties can be attached to titanium surfaces ...
Determination of fluid leakages in the different screw-retained implant-abutment connections in a mechanical artificial mouth
(Springer, 2015-07-15)
This study shows the potential risk of microfiltration between two different types of implant-abutment connections screwed at 45 Ncm: external and internal. For the first time the use of a mechanical ...
Fracture and fatigue of titanium narrow dental implants: new trends in order to improve the mechanical response
(MDPI, 2019-11-12)
Sixty-four fractured commercially pure titanium (cp-Ti) narrow dental implants (NDIs) with similar macrogeometry and connection designs were studied after different implantation times in humans in order ...
