Short implants (<8mm) versus longer implants (≥8mm) with lateral sinus floor augmentation in posterior atrophic maxilla: a meta-analysis of RCT`s in humans
(Medicina Oral, 2020)
Background: One of the greatest challenges that dentists face today is to rehabilitate severe atrophied alveolar ridges in partially and completely edentulous patients with implants. Despite the high ...
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, ...
Effect of stabilized martensite on the long-term performance of superelastic NiTi endodontic files
(MDPI, 2023)
One of the most used rotary files in endodontics is NiTi files due to their superelastic properties. This property means that this instrument has extraordinary flexion that can adapt to large angles ...
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 ...
Predictors of periapical bone healing associated with teeth having large periapical lesions following nonsurgical root canal treatment or retreatment: A cone beam computed tomography-based retrospective study
(Wiley, 2023)
Aim: Several factors influence the condition of the periapical tissues associated with root filled teeth. The primary objective of this study was to retrospectively evaluate the extent and speed of bone ...
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 ...
Evaluation of endovenous sedation using BIS monitoring in dentistry. A systematic review
(Medicina Oral, 2020)
Background: The aim of the present review was evaluate the utility and validity of the Bispectral Index (BIS) in dental treatment carried out under endovenous sedation, and compare its efficacy with ...
Biomimetic mineralized hybrid scaffolds with antimicrobial peptides
(Elsevier, 2021-08)
Infection in hard tissue regeneration is a clinically-relevant challenge. Development of scaffolds with dual function for promoting bone/dental tissue growth and preventing bacterial infections is a ...
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 ...
Effect of implantoplasty on roughness, fatigue and corrosion behavior of narrow diameter dental implants
(MDPI, 2023)
Implantoplasty (IP) is used in dental implants with peri-implantitis and aims to remove threads and polish rough surfaces in order to prevent bacterial colonization. As a result of this procedure, implant ...
