Influence of Tapered and External Hexagon Connections on Bone Stresses Around Tilted Dental Implants: Three-Dimensional Finite Element Method With Statistical Analysis
(Amer Acad Periodontology, 2014-02-01)
Background: The purpose of this study is to analyze the tension distribution on bone tissue around implants with different angulations (0 degrees, 17 degrees, and 30 degrees) and connections (external hexagon and tapered) ...
Relationship between external technical assistance and vulnerable schools in Chile: How it influences the process of improvement and changeRelatiónship between external technical assistance and vulnerable schools in Chile: how it influences the process of improvement and change
(2010)
Thanks to the recent changes in the Chilean regulations for education, external technical assistance (ATE) has evolved from previous government programmes to become an important element in the policy for school improvement. ...
Finite element computational modeling of externally bonded CFRP composites flexural behavior in RC beams
(TECHNO-PRESS, 2009)
This paper focuses on the flexural behavior of RC beams externally strengthened with Carbon Fiber Reinforced Polymers (CFRP) fabric. A non-linear finite element (FE) analysis strategy is proposed to support the beam flexural ...
Near-optimal online multiselection in internal and external memory
(Elsevier, 2016)
We introduce an online version of the multiselection problem, in which q selection queries are requested on an unsorted array of nelements. We provide the first online algorithm that is 1-competitive with the offline ...
Biomechanical evaluation of internal and external hexagon platform switched implant-abutment connections: An in vitro laboratory and three-dimensional finite element analysis
(Elsevier B.V., 2012-10-01)
Objectives. The aim of this study was to assess the effect of abutment's diameter shifting on reliability and stress distribution within the implant-abutment connection for internal and external hexagon implants. The ...
