Optimization of guanosine-based hydrogels with boric acid derivatives for enhanced long-term stability and cell survival
(Frontiers Media, 2023)
Tissue defects can lead to serious health problems and often require grafts or transplants to repair damaged soft tissues. However, these procedures can be complex and may not always be feasible due to ...
Comparison of the superelasticity of different nickel–titanium orthodontic archwires and the loss of their properties by heat treatment
(Springer Nature, 2016)
The aim of this work is to describe and compare mechanical properties of eight widely used nickel–titanium orthodontic wires under uniform testing conditions and to determine the influence of the heat ...
Corrosion resistance and ion release of dental prosthesis of CoCr obtained by CAD-CAM milling, casting and laser sintering
(MDPI, 2020)
Corrosion resistance and ion release behavior have been evaluated for thirty dental restoration samples obtained by three different manufacturing systems: computer-aided design and manufacturing (CAD-CAM), ...
Mechanical properties and corrosion behavior of Ti6Al4V particles obtained by implantoplasty: an in vitro study. Part II
(MDPI, 2021)
In the field of implant dentistry there are several mechanisms by which metal particles can be released into the peri-implant tissues, such as implant insertion, corrosion, wear, or surface decontamination ...
Tuning mesenchymal stem cell response onto titanium-niobium-hafnium alloy by recombinant fibronectin fragments
(ACS Publications, 2016)
Since metallic biomaterials used for bone replacement possess low bioactivity, the use of cell adhesive moieties is a common strategy to improve cellular response onto these surfaces. In recent years, ...
Influence of the CAD-CAM systems on the marginal accuracy and mechanical properties of dental restorations
(MDPI, 2020)
The aim of this study was to compare the quality of different computer-assisted-design and computer assisted manufacturing systems (CAD-CAM) generated by only one scanner, focusing on vertical fit ...
Resonance frequency analysis by the Osstell system, using the transducer screwed to different healings abutments
(Sociedade Portuguesa de Estomatologia e Medicina Dentária, 2017)
Objectives: compare the ISQ values obtained by the Osstell ISQ, screwing the Smarpeg directly to the implant or to the new designed healing abutments of 2, 3.5 and 5 mm of height. Methods: 60 rough ...
Citric acid in the passivation of titanium dental implants: corrosion resistance and bactericide behavior
(MDPI, 2022)
The passivation of titanium dental implants is performed in order to clean the surface and obtain a thin layer of protective oxide (TiO2) on the surface of the material in order to improve its behavior ...
Advances in surfaces and osseointegration in implantology. Biomimetic surfaces
(Medicina Oral, 2015)
The present work is a revision of the processes occurring in osseointegration of titanium dental implants according to different types of surfaces -namely, polished surfaces, rough surfaces obtained ...
Polyethylene glycol pulsed electrodeposition for the development of antifouling coatings on titanium
(MDPI, 2020)
Titanium dental implants are widely used for the replacement of damaged teeth. However, bacterial infections at the interface between soft tissues and the implant can impair the functionality of the ...
