Influence of implant design and under-preparation of the implant site on implant primary stability: an In vitro study
(MDPI, 2020)
The aim of this study was to evaluate the effects of different implant sites an under-preparation sequence associated with two different implant designs on implant primary stability measured by two ...
Influence of different CoCrMo counterfaces on wear in UHMWPE for artificial joints
(Scientific Research Publishing, 2011)
Wear tests were carried out to study the effect of various counterface materials in the wear behaviour of Ultra High Molecular Weight Polyethylene (UHMWPE). The materials used as counterfaces were based ...
Relevant design aspects to improve the stability of titanium dental implants
(MDPI, 2020)
Post-extractional implants and immediate loading protocols are becoming much more frequent in everyday clinical practice. Given the existing literature about tapered implants, the objective of this paper ...
Biofunctionalization with a TGFβ-1 inhibitor peptide in the osseointegration of synthetic bone grafts: an in vivo study in beagle dogs
(MDPI, 2019-09-27)
Objectives: The aim of this research was to determine the osseointegration of two presentations of biphasic calcium phosphate (BCP) biomaterial—one untreated and another submitted to biofunctionalization ...
Do titanium mini-implants have the same quality of finishing and degree of contamination before and after different manipulations? An in vitro study
(MDPI, 2021)
Evaluate the quality of finishing and degree of contamination before and after handling and surface treatment of titanium (Ti) orthodontic mini-implants (OMIs). A scanning electron microscope (SEM) study ...
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 ...
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 ...
In vitro corrosion behavior of lingual orthodontic archwires
(Hindawi Publishing Corporation, 2011)
To investigate the in vitro electrochemical corrosive behavior of archwires used in lingual orthodontics and the effects on the phase transition temperatures. Materials and Methods. Six different types ...
Ion release from dental implants, prosthetic abutments and crowns under physiological and acidic conditions
(MDPI, 2021)
Ion release from dental implants and prosthetic restoration can affect osteointegration and implant viability over a long period of time. Therefore, the aim of this study was to study the ion release ...
