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 ...
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 ...
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 ...
Use of porous titanium trabecular as a bone defect regenerator: in vivo study
(MDPI, 2022)
The application of porous materials is increasingly being used in orthopaedic surgery due to its good results. Bone growth within the pores results in excellent mechanical fixation with the bone, as ...
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 ...
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 ...
In vitro study of preload loss in different implant abutment connection designs
(MDPI, 2022)
The stability and integrity of the abutment-implant connection, by means of a screw, is fallible from the moment the prosthetic elements are joined and is dependent on the applied preload, wear of the ...
Roughness and wettability effect on histological and mechanical response of self-drilling orthodontic mini-implants
(Springer Nature, 2016)
Self-drilling orthodontic mini-implants can be used as temporary devices for orthodontic treatments. Our main goal was to evaluate surface characteristics, roughness and wettability, of surface modified ...
Mechanical characterisation and biomechanical and biological behaviours of Ti-Zr binary-alloy dental implants
(Hindawi, 2017)
The objective of the study is to characterise the mechanical properties of Ti-15Zr binary alloy dental implants and to describe their biomechanical behaviour as well as their osseointegration capacity ...
Two different strategies to enhance osseointegration in porous titanium: inorganic thermo-chemical treatment versus organic coating by peptide adsorption
(MDPI, 2018)
In this study, highly-interconnected porous titanium implants were produced by powder sintering with different porous diameters and open interconnectivity. The actual foams were produced using high cost ...
