Shear bond strength of nanohybrid composite to biodentine with three different adhesives
(MDPI, 2019)
Biodentine® is a bioactive dentin coating widely used for dental restoration; however, its adhesion to the substrate could limit its clinical success. The aim of this study was to evaluate the shear ...
Prospective clinical trial on the effectiveness of topical anesthetic in second stage surgeries of dental implants
(Peertechz Publications, 2017)
Objectives: The aim of this study is to evaluate the effectiveness of gel topical anaesthesia in second surgeries of dental implants according to the different treated areas of the oral cavity, as well ...
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 ...
Blood absorption capacity of different xenograft bone substitutes. An in-vitro study
(Medicina Oral, 2019-11)
Background: Commercially available xenograft blocks, claim to have adequate characteristics to interact with biological media and thus permitting biological fluid absorption. The objective of this in ...
Danger zone analysis using cone beam computed tomography after apical enlargement with K3 and K3XF in a manikin model
(Medicina Oral, 2016)
Background: The objective of the study was to evaluate and compare how apical enlargement with K3 and K3XF nickel-titanium (NiTi) rotary instruments reduces the root thickness in the danger zone and ...
Surgical-orthodontic approach for facial rejuvenation based on a reverse facelift
(Springer Nature, 2019)
Background: Orthodontic treatment combined with a maxillomandibular advancement (MMA) can be an effective option for patients who need not only corrected occlusion but also facial rejuvenation. In this ...
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 ...
