Accuracy of implant casts generated with conventional and digital impressions: an In vitro study
(MDPI, 2018)
Purpose: The aim of this study was to compare the accuracy of digital dental impressions with the accuracy of impressions obtained via conventional techniques. Methods: Two different master models were ...
Enhanced osteoconductivity on electrically charged titanium implants treated by physicochemical surface modifications methods
(Elsevier, 2019-06)
Biomimetic design is a key tenet of orthopedic device technology, and in particular the development of responsive surfaces that promote ion exchange with interfacing tissues, facilitating the ionic ...
Biofunctional polyethylene glycol coatings on titanium: an in vitro-based comparison of functionalization methods
(Elsevier, 2017)
Three methods for the production of Polyethylene glycol (PEG) coatings on titanium are compared, i.e. plasma polymerization, electrodeposition and silanization. The compared deposition methods presented ...
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 ...
Mechanical and microstructural characterization of new nickel-free low modulus beta-type titanium wires during thermomechanical treatments
(Elsevier, 2015)
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 ...
Functionalization of CoCr surfaces with cell adhesive peptides to promote HUVECs adhesion and proliferation
(Elsevier, 2017)
Biomimetic surface modification with peptides that have specific cell-binding moieties is a promising approach to improve endothelialization of metal-based stents. In this study, we functionalized CoCr ...
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 ...
Cell adhesive peptides functionalized on CoCr alloy stimulate endothelialization and prevent thrombogenesis and restenosis
(John Wiley & Sons, 2017)
Immobilization of bioactive peptide sequences on CoCr surfaces is an effective route to improve endothelialization, which is of great interest for cardiovascular stents. In this work, we explored the ...
NiTi superelastic orthodontic archwires with polyamide coating
(Springer, 2013-10-24)
Twenty orthodontic archwires with 55.2 % Ni and 44.8 % Ti (% weight) were subjected to a dipping treatment to coat the NiTi surface by a polyamide polymer. It has been selected a Polyamide 11 due to its ...
Influence of the elastic modulus on the osseointegration of dental implants
(MDPI, 2019-03-25)
The load transfer from metallic prosthesis to tissue plays an important role in the success
of a designed device. From a mechanical behavior point of view, the load transfer will be favored
when the ...
