Mineralization of titanium surfaces: biomimetic implants
(MDPI, 2021)
The surface modification by the formation of apatitic compounds, such as hydroxyapatite, improves biological fixation implants at an early stage after implantation. The structure, which is identical to ...
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, ...
Biofunctionalization strategies on tantalum-based materials for osseointegrative applications
(Springer Nature, 2015)
The use of tantalum as biomaterial for orthopedic applications is gaining considerable attention in the clinical practice because it presents an excellent chemical stability, body fluid resistance, ...
Installing multifunctionality on titanium with RGD-decorated polyurethane-polyurea roxithromycin loaded nanoparticles: toward new osseointegrative therapies
(Wiley, 2015)
A novel class of polyurethane-polyurea nanoparticles (PUUa NPs) to install multifunctionality on biomaterials is presented. Biofunctionalization of titanium with roxithromycin loaded RGD-decorated PUUa ...
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 ...
Porous titanium-hydroxyapatite composite coating obtained on titanium by cold gas spray with high bond strength for biomedical applications
(Elsevier, 2019-04-24)
The lack of bioactivity of titanium (Ti) is one of the main drawbacks for its application in biomedical implants since it can considerable reduce its osseointegration capacities. One strategy to overcome ...
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 ...
Biological roles and delivery strategies for ions to promote osteogenic induction
(Frontiers Media, 2021-01-14)
Bone is the most studied tissue in the field of tissue regeneration. Even though it has intrinsic capability to regenerate upon injury, several pathologies and injuries could hamper the highly orchestrated ...
