Relevant aspects of the dental implant design on the insertion torque, resonance frequency analysis (RFA) and micromobility: an in vitro study
(MDPI, 2023)
The major problems for the osseointegration of dental implants are the loosening of the screw that fixes the dental implant to the abutment and the micromovements that are generated when mechanical loads ...
Incidence of peri-implantitis and relationship with different conditions: a retrospective study
(MDPI, 2022)
Articles on the prevalence of peri-implant diseases showed that 90% of peri-implant tissues had some form of inflammatory response and a prevalence of peri-implantitis from 28% to 51% according to various ...
Evaluation and comparison of oral health status between spanish and immigrant children residing in Barcelona, Spain
(MDPI, 2022)
The present study aimed to evaluate and compare the level of oral health among Spanish and immigrant children residing in Barcelona, Spain. Oral health status was evaluated in 1400 children aged 3 to ...
In vitro comparison of the accuracy of four intraoral scanners and three conventional impression methods for two neighboring implants
(Public Library of Science, 2020)
Purpose: To determine whether the accuracy of two-implant model impressions taken with optical scanners was inferior to that of those taken with elastomeric materials. Materials and Methods: Impressions ...
Influence of static navigation technique on the accuracy of autotransplanted teeth in surgically created sockets
(MDPI, 2022)
The aim of this study was to analyse and compare the position of single-rooted autotransplanted teeth using computer-aided SNT drilling and conventional freehand (FT) drilling, by comparing the planned ...
Danger zone analysis using cone beam computed tomography after apical enlargement with K3 and K3XF in a manikin model
(Medicina Oral, 2016)
Background: The objective of the study was to evaluate and compare how apical enlargement with K3 and K3XF nickel-titanium (NiTi) rotary instruments reduces the root thickness in the danger zone and ...
Surgical-orthodontic approach for facial rejuvenation based on a reverse facelift
(Springer Nature, 2019)
Background: Orthodontic treatment combined with a maxillomandibular advancement (MMA) can be an effective option for patients who need not only corrected occlusion but also facial rejuvenation. In this ...
Clinical outcomes and associated factors in the treatment of peri-implant mucositis, combining mechanical debridement and prosthesis modification: a 30-month follow-up prospective case series
(John Wiley & Sons, 2022)
Aim: To evaluate the clinical outcome and the associated factors of a treatment protocol for peri-implant mucositis. Materials and Methods: Patients were evaluated 30 months after a treatment protocol ...
Mechanical and microstructural characterization of new nickel-free low modulus beta-type titanium wires during thermomechanical treatments
(Elsevier, 2015)
NiTi alloy is the only practical shape memory alloy (SMA) in biomedical use because of its excellent mechanical stability and functionality. However, it is estimated that between 4.5% and 28.5% of the ...
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 ...
