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 ...
Influence of the titanium implant surface treatment on the surface roughness and chemical composition
(MDPI, 2020)
The implant surface features affect the osseointegration process. Different surface treatment methods have been applied to improve the surface topography and properties. Trace of different elements may ...
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 ...
Development of biomimetic NiTi alloy: influence of thermo-chemical treatment on the physical, mechanical and biological behavior
(MDPI, 2016)
A bioactive layer, free of nickel, has been performed for its greater acceptability and reliability in clinical applications for NiTi shape memory alloys. In the first step, a safe barrier against Ni ...
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 ...
Effect of different implant designs on strain and stress distribution under non-axial loading: a three-dimensional finite element analysis
(MDPI, 2020)
Implant design evolved alongside the development of implant therapy. The purpose of this finite element analysis (FEA) study was to analyze the influence of different implant designs on the stress and ...
Mechanical properties of CoCr dental-prosthesis restorations made by three manufacturing processes: influence of the microstructure and topography
(MDPI, 2020)
The aim of this study is to compare the mechanical properties of three different dental restorations’ manufacturing processes (CADCAM milling, casting and laser sintering) generated by only one laboratory ...
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 ...
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 ...
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 ...
