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 ...
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 ...
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 ...
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 ...
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 ...
The role of hardness and roughness on the wear of different CoCrMo counterfaces on UHMWPE for artificial joints
(Springer, 2011)
Wear tests were carried out to study the effect of the hardness and roughness with various counterface materials on UHMWPE wear behaviour. The materials used as counterfaces were based on varieties of ...
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 ...
Silver deposition on titanium surface by electrochemical anodizing process reduces bacterial adhesion of Streptococcus sanguinis and Lactobacillus salivarius
(John Wiley & Sons, 2015)
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 ...
